Butter is made by churning cream or milk to separate the solid butterfat from the liquid. It is composed of approximately 80% fat, 15% water, and 5% milk solids. The fat in butter is mostly composed of triglycerides of fatty acids like palmitic acid, oleic acid, stearic acid, and myristic acid. Butter is produced through processes of harvesting, aging, churning, washing, and salting cream or milk. It has various applications including use as a spread, in baking, for flavoring foods, and in hair and skin treatments. Butter must be refrigerated and kept away from light and odors to prevent spoiling.

1. BUTTER:
INTRODUCTION:
Definition: Margarine is water in oil emulsion that is an exceptionally consolidated type of liquid
milk got by agitating Its shading ranges from yellow to white. It liquefies just underneath body
temperature(32–35 °C)
• Biological name ___ Latin butyrum__ the word spread infers (by means of Germanic
dialects) from the Latin butyrum, which is the Latinization of the Greek βούτυρον (bouturon). This might be
a compound of βοῦς (bous), "bull, dairy animals" + τυρός (turos), "cheddar", that is "bovine cheddar".
• Chemical name ___ Phenol, 4, 4’-(1-methylethylidene) bis [2,3,5,6-tetrachloro- Description:
Butter acids is found in milk and milk products.
History:
The primary reference to spread in our recorded history was found on a 4,500-year-old limestone
tablet showing how margarine was made. It is for the most part accepted the word spread starts from the
boutyron, Greek for "cow cheddar", anyway it might have originated from the language of cows grouping
Scythians. The soonest margarine would have been from sheep or goat's milk; steers are not thought to have
been tamed for an additional thousand years. An antiquated technique for margarine making, despite
everything utilized today in parts of Africa and the Close East, includes a goat skin half loaded up with milk,
and expanded with air before being fixed. The skin is then hung with ropes on a tripod of sticks, and shook
until the development prompts the arrangement of margarine.
In the Mediterranean atmosphere, unclarified margarine ruins quickly unlike cheddar, it's anything but
a down to earth strategy for protecting the supplements of milk. The antiquated Greeks and Romans
appeared to have thought about spread as a food fit more for the northern brutes. In the Characteristic
history, pliny the Senior calls margarine "the most fragile of food among savage countries'', and proceeds to
portray its properties. Afterward, the doctor Galen likewise depicted margarine as a restorative specialist as
it were.
CHEMICAL COMPOSITION OF BUTTER:
The fat substance of spread extents from 80% to 86%, 15% water and 5% milk solids.
Spread likewise contains protein, calcium and phosphorous (about 1.2%) and fat-dissolvable nutrients and
vitamins A, D and E. Synthetically spread fat comprises basically of a blend of triglycerides, especially
those got from unsaturated fats, for example, palmitic, oleic, myristic, and stearic acids.

 Special Margarine:
This gathering incorporates some margarine that are not ordinarily accessible and those which are false spreads.
These include:
1. Whey Margarine: Whey is the fluid which isolates fromthe curd while making cheddar. The butterfat got from
the whey might be utilized to deliver spread, or it might be added to new cream/milk before it being prepared into
margarine. Because of its source,this margarine has a black out mushy flavor.
2. Milk mixed Margarine: Amounts of milk are mixed into spread, subsequently expanding the dampnesssubstance
to 24% (max.).
3. Powdered Margarine: This is splash dried spread containing 80% milk fat and non-greasy solids. It is created
for an enormous scope in Australia and is utilized basically in the Bread kitchen exchange.
4. Compound Spread: These are made by including a specific common flavor or shading to margarine, contingent
upon the kind of food with which it is served.It is commonly utilized as a backup for example Lobster Margarine,
Parsley Spread and so on.
5. Cocoa Spread: This is certifiably not a genuine margarine, rathergot by pounding the cocoa beans.It is the most
costly fixing utilized in chocolate making. Cocoa spread substitutes,utilizing palm oil, are likewise accessible.
6. Nutty spread: It is a glue like substance got by crushing simmered peanuts that might be additionally emulsified
and seasoned.
 MANUFACTURING OF MARGARINE:
The assembling of creamery margarine happens in fourprinciple stages, as referenced:
1. Holding: The cream(35%) is sanitized at 95°C (203°F) and held for 2 to 4 seconds.It is then cooled to 4.5°C
(40°F) and held there for a few hours to guarantee the uniformsolidifying of the fat globules.
2. Aging When the finished result will be a matured margarine orlactic spread, a "starter" (which is a lab culture of
corrosive delivering microbes) will be included during the Holding stage, in which the holding temperature will be
15.5-18.5°C (60-65°F)for 3 to 4 hoursbefore being cooled to 4.5°C(40°F). This gives the spread an a lot more full
flavor. Be that as it may, the flavor will in general blurand subsequently the matured creamspread has a shorter life
than the sweet creammargarines.This stage will be precluded when making the sweet creammargarine.
3. Stirring The agitating of creamis done in huge tempered steel beats that hold around 1000 gallonsof cream. The
temperature must not surpass more than 4°C. The stirs are turned while inside rollers go through the cream. This
breaks the envelope of non-fat particles/solids that encompass the little fat globulesand combine to shape bigger
gatherings of margarine fat.The envelope is scattered in the flimsy fluid piece of the creamto shape buttermilk. After
around 30 minutes of beating,the margarine isolatesout asgrains and buoys in the buttermilk.The buttermilk is
deliberately depleted away and utilized fordifferent purposes.

4. Washing and Salting The margarine grains are currently washed with ice water to evacuate any hints of
buttermilk left on the outside of each grain,so as to augment the keeping quality. Ice water additionally assists with
solidifying margarine grains.Salting should be possible in two different ways:
a. By including fine grains of dairy salt.
b. By absorbing a salt water answer for10-15 minutes and permitting the margarine to assimilate it.
The amount of salt included normally normal 1% for aged creammargarine and 1.5% fornew creamspread.Salt
adds to enhance and improves the keeping quality. The spread grains are then worked into a smooth strong mass by
turning the agitates gradually for10-15 minutes,at that point gauged and pressed.Shading (annatto) may likewise be
included at thisstage. On the off chance that unsalted spread is required,the salting stage is precluded.
 Applications of Margarine:
1. As a spread for bread,toast and scones.
2. As a fundamental fixing in cake making and cake-production.
3. Utilized as a backup (compound spread).
4. To improve the taste and kind of soups and sauces.
5. As a cooking medium(The smoke purpose of spread fat is just 127-130°C; so a vegetable oil ought to be utilized
when high cooking temperatures are required).
6. for spread models.Spread is accessible in 10 Gms, 100 Gms and 500 Gms packs in the market.
7. Use margarine to treat dry hair.
8. Expel sap fromskin utilizing margarine.
9. Use margarine to keep shape off cheddar.
 Storage:
Margarine is a transient itemand will in general free flavor and go rotten on delayed capacity. Introduction to
daylight can cause it to go malodorous quicker.
It must be put away at refrigerated temperatures (2°C), all around wrapped and away from solid enhanced
nourishments, for it assimilatessmells and flavors without any problem. Whenever bought in mass, it very well may be
solidified at - 25 to - 35°C.
A decent quality spread ought to have a perfect flavor and smell normal for the kind of margarine, have a nearby
body, a waxy surface, be of uniformshading, have a uniformconveyance of salt (wheneverincluded),be spotless in
appearance and have a nonappearance of any free dampness. Ghee is acquired by explaining margarine.Margarine
is warmed to vanish water. Unadulterated ghee hasa higherkeeping quality and is a decent cooking mediumand a
shortening specialist utilized in Indian Food.
