Sterilized milk has advantages like long shelf life without refrigeration and a soft curd formation, but has disadvantages of increased production costs and some loss of vitamins. The detailed sterilization process involves clarifying, homogenizing, and heating milk to 108-111°C for 25-35 minutes in a batch or continuous sterilizer before cooling and storage.
This document discusses the industrial production of vinegar (acetic acid). Vinegar is produced through a two-step fermentation process - alcoholic fermentation followed by acetous or acetic acid fermentation. There are three main methods of vinegar production - Orleans process (slow process), Fringe process (quick process), and submerged fermentation process. The Fringe process uses fringe generators that are packed with wood shavings to provide a large surface area for bacterial film growth, allowing ethanol to be rapidly oxidized to acetic acid within 1-2 weeks. The generated vinegar is then aged, clarified, bottled and pasteurized for consumption.
INTRODUCTION:
BREAD is a dietary product obtained from the fermentation and the subsequent baking of a dough mainly made of cereal flour and water, made in many different ways and sometimes enriched with typical regional ingredients.
Ingredients of bread:
Flour is the bulking ingredient of bread, it forms the structure of the product,contains gluten which helps to form an elastic stretchy dough.
Yeast is a raising agent. Yeast produces gases to make the bread rise.
Salt is required to bring out flavour in the bread, it is used in small quantities.Too much of this ingredient will stop the yeast from growing.
Yeast needs energy to grow. Sugar provides the food for the yeast; it is needed to help the yeast grow.
Water is used to bind the flour together and helps to form the structure of the bread.
Fats or oils improve the texture of the bread, preventing it from going stale quickly.
Starter culture:
Baker's yeast is the common name for the strains of yeast commonly used as a leavening agent in baking bread and bakery products, where it converts the fermentable sugars present in the dough into carbon dioxide and ethanol. Baker's yeast is of the species Saccharomyces cerevisiae, which is the same species (but a different strain) commonly used in alcoholic fermentation which is called brewer's yeast.
Bread Making Process
Mixing has two functions: to evenly distribute the various ingredients and allow the development of a protein (gluten) network to give the best bread possible.
Once the bread is mixed it is then left to rise (ferment).
Any large gas holes that may have formed during rising are released by kneading.
Moulding the dough into desired loaf shape.
During the final rising the loaf fills with more bubbles of gas, and once this has proceeded far enough they are transferred to the oven for baking.
The loaf is then placed in a preheated oven to bake. Such a high heat will kill the yeast, thus stopping its process of rising and growth.
The whole loaf is cooled to about 35°C before slicing and wrapping can occur without damaging the loaf.
Types of Bread
1. White Bread
2. Brown Bread
3. Wholemeal bread
4. Rye bread
Apart from above there are several types like Crisp bread, Flatbread is often simple, made with flour, water, and salt.

Cheese making involves several steps:
1) Milk is acidified through the addition of starter cultures which produce lactic acid.
2) Rennet is added to further coagulate the milk into a solid curd.
3) The curd is cut and heated to separate the whey.
4) The curd is salted, shaped, and pressed to form the final cheese shape.
5) The cheese is aged/ripened through carefully controlling temperature, humidity, and introducing molds to develop flavor.
Microwave cooking generates heat within food using microwaves that penetrate up to 5 cm deep, heating the entire item quickly. Small pieces cook very fast as microwaves reach their centers, while larger pieces cook more slowly from the outside in. Microwave cooking is fast but requires careful time control and additional broiling to brown or crisp foods.
Condensed milk was invented in the 1850s by Gail Borden as a way to preserve milk for long periods. It involves evaporating water from milk to increase its concentration and shelf life. Sugar is often added to further preserve it. The processing involves standardizing, heating, condensing the milk in a vacuum, homogenizing, cooling and crystallizing it before packaging. Condensed milk can last up to a year unopened but only 2-3 weeks once opened. It is commonly used in desserts, drinks, ice cream and confectionaries due to its thickness and sweetness.

Modern cheese making involves several key steps: 1) Milk intake and standardization including pasteurization; 2) Adding starter culture and rennet to coagulate the milk; 3) Cutting the coagulated curds and heating/stirring to separate the whey; 4) Curd transformation where the curds are piled and flipped to expel more whey; 5) Pressing to give the cheese its shape and complete curd formation; 6) Optional curing for aged cheeses to develop flavor and texture. The processes aim to safely transform raw milk into cheeses with varied flavors and textures through bacterial culture and enzyme additions, heating, draining, pressing, and sometimes curing.
Cheese ripening involves several key steps:
1) Conversion of liquid milk into a solid curd through the addition of rennet which causes casein micelles to coagulate into a network trapping milk fat.
2) Bacterial cultures are added which carry out fermentation, producing various flavors through proteolysis and lipolysis.
3) Ripening occurs through the action of enzymes from milk, starters, or those added, which further break down proteins and lipids over time, influencing texture and developing flavor.

Common cheeses produced in India include processed cheese, cheddar, mozzarella, and paneer. The organized cheese market is growing at around 18% annually but per capita consumption is still low compared to other countries. Further research is ongoing to develop new lower-fat and lower-salt cheese varieties suitable for the Indian population.
Cheese and kefir are the important spin -off from microbes. These products often get contaminate by various process. Due to large scale commercialization and consumerism many techniques are performed.
1. Cheese can be made from pasteurized or raw milk, with raw milk cheeses requiring aging of at least 60 days to reduce pathogens.
2. Cheese production involves using starter cultures like Lactococcus lactis to ferment the milk and adjunct cultures to provide flavor.
3. The general cheese making process includes standardizing milk, adding cultures, coagulating with rennet, cutting and cooking the curd, salting, pressing into blocks, and aging.
Cheese making is an ancient process that involves coagulating the casein in milk using rennet or lactic acid to produce curd. The curd is then pressed, shaped, and aged to produce different varieties of cheese. The document discusses the key steps in cheese making including preparation of milk, addition of starter cultures, coagulation, processing the curd, salting, and ripening. It also describes the major types of cheeses classified by moisture content and ripening method as well as the microorganisms involved and physical changes that occur during the ripening process.
This presentation involves with the fermented products of dairy items and their manufacturing procedures. This presentation includes production of cheese, buttermilk, yoghurt, kefir and sour cream
Cheese is made through a multi-step production process. Milk is standardized, pasteurized, cooled, and inoculated with starter bacteria. Rennet is added to coagulate the milk into a curd. The curd is cut, heated, drained, pressed, salted, and aged. The aging process can last from a few months to years depending on the cheese variety. The finished cheese is then packaged.

This document provides an overview of cheese production and types. It discusses the definition of cheese as a food derived from milk produced through coagulation. It describes the microorganisms used such as bacteria and fungi. The production process involves coagulation, cutting the curd, pressing, salting, and aging. Different types of cheeses are produced depending on origin of milk, processing, bacteria, mold and aging. Processed cheese is made from traditional cheese with added ingredients to make it melt smoothly.
Bakers yeast production and characteristicsHazem Hussein
The document summarizes the process for producing bakers' yeast. It begins with raw materials like molasses which are sterilized and supplemented with nutrients. The yeast is then grown through several fermentation stages in large tanks. It is processed by centrifuging and filtering to produce cream yeast or compressed granular and cake yeast. The finished yeast contains proteins, carbohydrates and other components that can vary depending on production methods and conditions.
Cheese is a very popular food produced worldwide from the milk of ruminants using a combination of physical treatments. Key milk components for the transformation of milk into curd are casein and calcium. The majority of cheese varieties are based on the curd of modified casein micelles that result from the enzymatic rennet clotting of milk in the presence of calcium ions. The remarkable ability of the spontaneous syneresis of rennet-induced curds can be adjusted to the desired level by biological acidification, cutting, stirring, heating, pressing and salting in order to achieve the desired level of water removal in the form of whey. The mode of curdling (acid or rennet coagulation), the conditions, and the combinations of curd treatments result in numerous cheese varieties with different appearances, textures, flavors and shelf lives. Moreover, most of them are kept under specific temperature and humidity conditions to ripen for a short or a considerable amount of time. The classification of cheese varieties is not unambiguous and can be based on various criteria. For example, cheeses can be classified according to their moisture content related to yield and shelf life or according to specific features related to the treatments applied during cheesemaking and ripening. During ripening, the main solid constituents of young cheese—fat and caseins—undergo changes that increase the concentration of small size compounds in cheese—such as peptides, amino acids, small volatile molecules—control moisture loss and configure textural properties. In particular, the compounds of mature cheese flavor result from complicated biochemical pathways that take place during cheese ripening or even storage.

This document provides information on cheese production. It discusses that cheese can be made from pasteurized or raw milk, with raw milk imparting different flavors. The main steps of cheese production include standardizing milk, heating it, inoculating it with bacterial cultures, adding rennet to coagulate the milk into curd, draining whey, pressing curd into blocks, and aging cheese. Key aspects are using starter cultures to lower pH and prevent spoilage, as well as adjunct cultures to enhance flavors. The document also outlines common cheese varieties and ingredients used in production.
According to legend, cheese was first made accidentally by a shepherd carrying milk in a pouch made from a sheep's stomach. The combination of heat and enzymes in the stomach lining caused the milk to separate into curds and whey. Cheese making allows milk nutrients to be preserved in a compact, nutritious, and palatable form. There are over 400 varieties of cheese made from different milks, using different manufacturing methods, ripening periods, and sizes. The characteristics of each cheese depend on factors like the type of milk used, temperature, acidity, humidity, coagulating agents, and microorganisms used during ripening.
This document presents information about cheese from a presentation given by Ankur Gupta. It defines cheese and describes its classification based on moisture content, including soft, semi-hard, hard, and very hard cheeses. The general manufacturing process for cheese is outlined involving steps like coagulation, curd preparation, pressing, salting, and ripening. Specific methods for making cottage cheese and cheddar cheese are also summarized. Common defects in cheddar cheese and their causes are listed. Popular cheese brands in India are noted along with Amul being a major brand. The conclusion restates that cheese is obtained from milk through coagulation and draining and that acceptability remains a concern for some due to the use of rennet.

The conclusion restates that cheese is obtained from milk through coagulation and draining and that acceptability remains a concern for some due to the use of rennet.
The key steps in the cheese making process are:
A. Curdling the milk using rennet or an acidifying culture. This causes the milk proteins to coagulate and separate from the whey.
B. Cutting the coagulated curd into smaller cubes to allow more whey to drain off.
C. Heating, pressing, salting and aging the curds, during which acidification and bacterial/fungal cultures further develop the characteristics of the specific cheese variety.

3. FLAVOR DEVELOPMENT
IN CHEESEMAKING
Many factors influence cheese flavor,
but there are PIVOTAL STEPS that explain
why a cheese tastes the way it does.
These steps are the FOCUS of our
presentation today
4. KEY FACTORS SHAPING CHEESE
FLAVOR DEVELOPMENT
1. CHEESEMAKER SKILL
2. MILK TYPE & QUALITY
3. TERROIR INFLUENCES
4. STARTER CULTURE
5. CURD STRUCTURE DEVELOPMENT
6. SALT MANAGEMENT
7. RIND TYPE
8. RIPENING PRACTICES
9. STORAGE & HANDLING
5. 1. CHEESEMAKER SKILL
Cheesemaker skill is the SINGLE MOST IMPORTANT
FACTOR determining the quality and flavor of the cheese.
A skilled cheesemaker can compensate for the shortcomings in the
milk, the facility and the environment, but high quality milk and ideal
circumstances will not compensate for shortcomings in the
cheesemaker’s skill
6. THE ART OF CHEESEMAKING
Good cheesemaking is the result of GOOD CHOICES
by the cheesemaker in terms of:
Milk selection
Flavor complexity
Terroir influence
Make process consistency
Ripening practices
7. 2. MILK AND FLAVOR
Milk choice is an IMPORTANT CREATIVE CHOICE for the
cheesemaker and one dictated by a number of factors
8. UNDERSTANDING MILK
Milk contributes to CHEESE FLAVOR depending on:
Animal used cow, sheep or goat
Breed used Holstein vs. Jersey
Feed given to the animal
Overall quality of the milk
Blended with other milks
Skimmed, partially skimmed or has cream added
Raw or pasteurized
9. 3. ENVIRONMENT AND FLAVOR: TERROIR
Much is said about “terroir” today. Terroir can significantly influence
cheese flavor. But for it to do so the cheesemaker must carefully
PLAN it into the cheesemaking process.
10. UNDERSTANDING
TERROIR
A French expression meaning OF THE SOIL
Refers to diverse environmental influences on a
food’s flavor development such as soil composition,
microclimate and native microbiology
11. TERROIR HAS A LONG
TRADITION IN EUROPE
Terroir is the result of a well-established PARTNERSHIP
between the government and the farmers to steward the
environment.
12. TERROIR PRACTICES ARE
TAKING HOLD IN U.S.
Diversify local flora in feed
Graze herd on natural grasses
Use seasonal milk
Use batch culture process that
captures indigenous microorganisms
Add locally grown herbs to
cheese
Foster unique aging room
microenvironment
We are creating our own tradition. There are several methods
cheesemakers can use to INTRODUCE TERROIR
13. 4. THE ROLE OF STARTER
CULTURE
STARTER CULTURE is added to the milk in the vat and
determines the type of cheese being produced, influencing both
flavor and texture.
14. STARTER CULTURE
“Vat culturization” produces consistent flavor
“Batch culturization” can add terroir to cheese flavor
Beneficial LIVING BACTERIA impart flavor and texture through
fermentation and release enzymes that shape flavor
Starter culture
is alive with
bacteria
Starter culture
15. COMPLEXITY AND CHEESE
COMPLEXITY determines how we experience a cheese. It’s
important to note that complexity starts IN THE VAT. The
cheesemaker cannot later develop cheese qualities – such as
during aging – that are not created in the vat.
16. CULTURE VS. COAGULANT
Main coagulant used today is Microbial (chymosin)
Less impact on flavor than starter culture
Coagulation adds ENZYMES causing the milk to thicken and
separate into solids and liquids – CURDS AND WHEY
17. 5. CURD STRUCTURE
Flavor follows structure. Creating a good structure gives a cheese
the potential to develop great flavor.
Curd structure development is the heart of cheesemaking. How the
curds develop in the vat shapes the STRUCTURE of the cheese
and determines flavor and texture potential
18. STRUCTURE AND FLAVOR
Determined when the whey is drained from the curd
This is the point WHEN MILK BECOMES CHEESE
Structure of the curd forms a MATRIX OF PROTEINS
Matrix of
proteins
23. 6. SALT AND FLAVOR
Salt is more than a seasoning agent. It is an essential tool for
the cheesemaker to CONTROL flavor development and
ripening
24. THE ROLE OF SALT
SALT has three functions. It serves as a preservative, a way
to inhibit the growth of undesirable bacteria, and as a means
for determining how much moisture will remain in the
cheese.
25. ADDING SALT
There are THREE METHODS of salting cheese:
Salt added to fresh curd
Dry salt rubbed on cheese rind surface
Immersing cheese in salt brine
26. 7. RINDS & FLAVOR
Rind influences enzymatic activity in the cheese and
moisture loss during ripening. Rind also directly influences
flavor if it is consumed as part of experiencing the cheese.
The type of rind on the cheese, or whether the cheese has a rind at
all, directly affects FLAVOR DEVELOPMENT during ripening.
31. SURFACE RIPENED RINDS
Andante Soft-Ripened Mt. Tam
Triple Crème Brie
White or Bloomy Rind
Mold is added to the curd
or sprayed on the surface
32. SURFACE RIPENED RINDS
Schloss Liederkranz
Red Hawk
Washed Rinds
Surface is washed with whey,
brine or flavored liquid
33. 8. RIPENING AND FLAVOR
Proper ripening is a necessary step in bringing many cheeses to the
peak of flavor, but only if the cheese possesses the STRUCTURAL
QUALITIES that will be improved by further aging.
34. CHEESE RIPENING
Fermentation continues during the life of a natural cheese,
making changes that affect cheese flavor over time. The
cheesemaker can influence these changes by carefully
controlling the ripening environment
Success in ripening actually started back in the VAT and is
completed in the AGING ROOM
35. TERROIR IN THE
AGING ROOM
The cheesemaker can control the the ripening
environment to encourage terroir and influence flavor
development
Add indigenous influences such as local herbs
Cultivate microflora in the aging room over time
Age different cheeses in the same room
Manage airflow that brings in local bacteria
36. 9. STORAGE, HANDLING
AND FLAVOR
Generally speaking, the aim of good storage and handling is to
help PROTECT cheese quality and flavor, and not really improve
it, but that is an important reason why it must be done correctly.

38. PROPER CHEESE STORAGE
The goal is to keep cheese at the peak of flavor. Storage
and handling practices should mimic the cheesemaker’s
ripening room to help the cheese RECOVER from the
traumas experienced during shipping
Since natural cheese is a living food, with proper HANDLING
it usually can be coaxed back to its full flavor potential.
39. THE AFFINEUR
Until recently a European practice, affineurs
are now starting to appear in the U.S.
A skilled affineur can bring a cheese to the PEAK of
flavor just before sale

40. THE CHEESEMAKER’S ART
The cheesemaker creates and
manages an ECOSYSTEM of
living microorganisms and
their byproducts.
His or her SKILL in managing
the process is ultimately the
single most important factor
determining cheese quality
and flavor.
Editor's Notes
We are going to watch a short video demonstrating how fresh and dry jack are made at the Vella Cheese Company in Sonoma. It will help you follow when we dive into the vat to take a close look at how flavor gets in cheese.
As Lynne so ably explained, knowing the qualities of their milk, Cheesemakers then must decide what kind of cheese to make, their cheesemaking vision.
All other choices follow from that first choice. But some choices are more important to flavor than others and the choice of starter culture may be the most important of all because it determines complexity.
What is Starter Culture? It is a soup of many different kinds of beneficial, milk-sugar loving, living bacteria and their enzymes. They are carefully selected according to the kind of cheese a cheesemaker wishes to make. All cheeses, except a few fresh varieties, need culture.
Through the magic of fermentation, in this case, lactic fermentation, the living culture ferments milk sugar, lactose, into lactic acid, lending cheese its tartness and preserving the life-promoting nutrients of milk. It also releases enzymes that define flavor and texture.
How the starter is added to the vat also affects the flavor– if added directly to the vat in frozen or freeze-dried form, it creates consistency; if added as a batch, like sour dough bread, it adds a bit of local flavor to the cheese, a little “terroir.”
The more building blocks of flavor available in milk, the more potential flavors a cheesemaker has to work with. We call this Complexity.
Complexity starts in the vat with the starter culture. A cheesemaker can’t later develop qualities that aren’t there initially. It is a front end loaded process.
But more complexity isn’t always better. A fresh cheese or a young cheese need to be simple. It is the cheesemaker’s choice.
Either way, To nurture flavor you have to be skilled at managing complexity. Starter culture is alive, and working with it can be unpredictable. Many variables, like the weather are out of a cheesemakers control. To succeed cheesemakers follow a consistent make-process, the steps you take to make the cheese.
The difference between Starter Culture and Coagulant used in cheesemaking confuses some people. A coagulant is added to the vat around the same time as the starter to separate the gel-like curds from the liquid whey. It adds little to the flavor of cheese, unless too much is added, making cheese bitter.
There is also a misconception that animal based rennet is widely used as a coagulant. While a handful of cheeses are still made with animal rennet, most cheesemakers use microbial coagulants.
How curds develop in the vat shapes the structure of the cheese, determining the flavor and texture.
As it says on the slide, “Flavor follows structure.”
So lets consider cheese structure for a minute.
The enzymes released during the fermentation of the milk build a matrix of proteins we call Structure, the essential foundation of any cheese.
The structure determines what nutrients will be trapped in the cheese, defining potential flavors and texture. Whether fresh, sweet and moist– pungent, hard and dry, or tart, nutty and crumbly.
Traditionally, cheesemakers touched the curd in the vat to judge the progress of a cheese. In today’s sanitary cheese rooms, cheesemakers accomplish the same thing by monitoring the level of acidity in the vat, knowing the exact moment to drain the whey for the cheese he wants to make.
This brings up a key point, the moment when the whey is drained from the vat is the defining moment in making cheese– the moment when milk becomes cheese.
To illustrate the concept of structure we are going to show you some graphic proof that cheese is a living food. If the following slides seem a bit too graphic to you, please remember, they are the naked truth of how great cheese is formed.
In this first slide, we are seeing the curds right after the whey is drained. We see the protein fibers beginning to form a structure, easy to see in contrast to the plump round bits of butterfat.
As the bacteria in the culture release their enzymes the proteins change. This is a young feta, already having a clearly defined matrix.
Since this is a young cheese, the culture is still quite active. Notice the rod shaped, milk-sugar loving, beneficial, living bacteria trapped in the matrix.
Not exactly cuddly, but the flavors they create in cheese make them seem so.
In this slide you see a fully developed structure, that of an aged gouda, with the fat removed in order to take the picture. Notice how the structure has created spaces to hold the nutrients that make up the flavor and food value of the cheese.
As I mentioned earlier, the particular structure of this cheese and all others was determined by the level of acidity when the cheesemaker drained the whey.
Once the curd is drained, the next step is to add salt. Salt is more than just a seasoning agent in cheese.
Salt has 3 functions: First, it serves as a preservative, inhibiting the growth of undesirable bacteria. Second, it controls the rate a culture flourishes inside a cheese. And third, it helps control moisture content.
Think of salt as a chaperone whose job it is to slow the milk-sugar loving bacteria down so the don’t run out of food during ripening.
Cheese is salted in one of three ways, or in combination.
By adding salt to the fresh curd in the vat right after draining.
By rubbing salt on the surface.
Or by immersing the cheese in a salt bath called a brine.
Once the wheel is salted we move from the cheeseroom to the aging room. Our cheesemaker next creates the type of rind the cheese will have.
Rind is important to flavor. The rind controls moisture loss during ripening and, if eaten with the body of the cheese, it can have a profound influence on flavor.
There are four types of cheese rinds:
Rindless
Natural
Smooth
And Surface Ripened.
We will be tasting an example of each type as we discuss… (set up tasting)
At the risk of stating the obvious, rindless cheese is cheese without a rind.
They include most fresh cheeses, most blue cheeses as well as a cheddar or jack that is vacuum sealed in plastic. Since there is no rind the affect on flavor is neutral.
To head off a confusion, sealing in plastic doesn’t stop flavor development. It changes it subtly though as it continues to ripen in a vacuum.
When wrapped in foil, as in blue cheese or in a tub, like fresh cheese, or sealed in plastic, the wrapping takes the place of a rind to seal in moisture and keep unfriendlies out.
Lynne, what will we be tasting?
Natural rinds seal in moisture and flavor and keep unfriendlies out by working in harmony with nature rather than acting as a barrier. Many cheeses sport natural rinds. A common form is a natural rind cheddar.
The rind is formed most often by rubbing the surface with fat, encouraging molds in the ripening room to colonize the surface of the cheese, sealing the cheese and creating the rind.
To anticipate a possible question, the bandage in bandaged wrap cheeses is not about the rind, its about holding a larger wheel of cheese together so the curds can knit.
Lynne, what are we tasting?
Smooth rind cheeses are similar to Natural Rinds, only the surface of the cheese is kept scrupulously clean by frequent wiping. In the case of Gouda, which is wiped with vinegar, the rind is kept so pristine it is often called a “Perfect Rind.”
Surface ripened white or bloomy rinds directly affect flavor, especially if eaten with the cheese. White mold spores, cousins to penicillin, are added to the milk with the culture. sprayed on the surface, or allowed to develop naturally in the aging room. Ripened in humid conditions the cheese develops a pillowy white coating which helps ripen the cheese from the outside in. That is why you may notice a softer texture closer to the rind and a firmer one in the center.
And what tasty cheese are we going to sample this time, Lynne?
Surface ripened washed rinds are made by washing the surface of a cheese with whey, brine, wine, beer or spirits.
In a humid ripening room this moist surface is colonized by beneficial bacteria and yeasts. It develops a pungent reddish rind which both protects the cheese and profoundly affects the way the cheese ripens. The pungent flavor is quite pronounced if you eat the rind. And much more subtle and nutty if you just eat the body of the cheese.
Lynne, what lovely treasure are we going to taste?
With the choice of a proper rind, the first stage of cheesemaking is complete and it is ready to be ripened.
With proper guidance, adolescence leads to maturity, in people and in cheese. In cheese we call this process ripening. The relation of ripening to flavor is often misunderstood.
Ripening, some call it aging, is an important step in bringing cheese to the peak of flavor, but only if the cheese has the potential for flavor trapped in its structure.
Since Cheese is a front end loaded process, success in ripening starts in the vat, and is completed in the ripening room.
Because fermentation continues over time in natural cheese, a cheesemaker can manage the environment of the ripening room and turn flavor potential into delicious reality, but he can’t nurture flavors that don’t already exist in the cheese.
Controlling the ripening environment provides another opportunity to sneak into the cheese a bit more local flavor, a measure of terroir.
By
• Opening up the ripening room to local influences where allowed
• Or ripening different cheeses in the same room
• Or creating her own microclimate by cultivating microflora in the ripening room, depending on what local officials will allow. This is a photograph of the ripening room at Marin French Cheese. It has been in use since 1865. The microbes that have developed over time contribute to the special flavors of the cheeses ripened there.
And now we move from what a cheesemaker does to create flavor in Cheese to what you must do to maintain it. Once a cheesemaker deems their cheese ready it enters the distribution chain. Proper storage and handling throughout this chain will help protect cheese flavor, but not really improve it.
To paraphrase the great Chef Auguste Escoffier, the secret to good cooking is to start with good ingredients and not ruin them!
A cheese goes through many hands on its journey to your tummy. From the dairy, where the cheese is produced, ripened and wrapped [slide] by truck to Distributor [slide] where it is stored, cut, wrapped and distributed to the restaurant, retailer or final user. [slide] Cheeses are kept very cold, by law, so cold, it is at best in a state of suspended animation.
For example, the best temperature range for cheese flavor is 42 to 50 degrees, and an average humidity of 70-80%. Much higher temperature and humidity than is allowed during a cheese’s journey. As it lurches from too cold to too warm, it can be traumatized.
Therefore to keep cheese at its peak, its important to know the best way to store and handle it.
And what better way than to mimic the way a cheesemaker keeps his cheese as best you can?
That completes our presentation, but I would be remiss if I didn’t mention affinage, and the Affineur. Until recently only found in Europe, the affineur is a cheese professional skilled in best ripening practice, affinage. More and more we are finding cheesemongers who are practicing affinage in their stores. Buying some cheeses while young, other cheeses already somewhat ripened, and providing the ideal conditions for each cheese to develop its flavor, like a master winemaker.
While this contradicts my statement that you can’t improve a cheese in storage, we hope the practice of Affinage continues to grow in California and across the US so I can be proven wrong more regularly.
We have covered a lot of territory in our exploration of flavor in cheese.
Here we again have a picture of Ig Vella, master cheesemaker. He and his fellow cheesemakers are Scientists and Craftsmen who create and manage an ecosystem of living microorganisms and their byproducts. When they do it well they elevate cheesemaking to an artfor.
An unskilled cheesemaker may make good cheese one day, mediocre the next, both from the same high quality milk. A master like Ig Vella makes great cheese consistently, every batch, every wheel. All other factors are important, but I want to leave you with the thought that Cheesemaker Skill is the THE most important factor in making consistently great cheese.
How cheese is stored during the journey from dairy to consumer can make all the difference. I will now demonstrate a couple of strategies Professionals can use to keep cheese better, and some ways for the consumer.
.
Professionals know that wrapping cheese in plastic for long term storage is not a good idea as it can suffocate the cheese and encourage mold to grow. But consumers can do it if they are going to consume right away.
Professionals will unwrap aged cheeses and store in sealed food bins by family of cheese, using a dry paper towel to decrease humidity, or a corner of a wet one to increase it as needed. If keeping for more than a week to a week and a half they rub the surface of all but fresh, washed rind and white rind cheeses with olive or vegetable oil to protect against mold as well, as the mold will consume the easily available fat on the surface and not enter the cheese. It can then just be rubbed off. Each time they cut the cheese, they rub the cut face with a bit of oil. Once in awhile, at least every two weeks, they pop the top of the container to refresh the air, turn the cheese to balance the affect of gravity, and change the paper towel and the container.
For consumers we recommend wrapping in wax paper or aluminum foil instead of plastic, and storing in a plastic container and consuming right away. For a more long term storage, or with finer cheese, you can apply some of the professional techniques oultined above as well.
