Role of Microorganism and Enzymes in Food Preservation by Pallavi Wani.pptxPallavi Wani
Food preservation?
Food preservation is a process in whichFruits and vegetables are prevented from getting spoilt. The color, taste, and nutritive values of food is also preserved. Food products lasts for a long period of time: shelf life of food product is increased
Role of Microorganism in Food preservation
As the human population is increasing, we need to adopt new techniques for producing qualitative and nutritious food. These microorganisms can be used to cope with the shortage of food supply.
Microorganisms are an important part of the food industry as these are helpful in food preservation and production.
Usually, microorganisms are used in making dairy products (yogurt and cheese), fermented vegetables (olives, pickles, and sauerkraut), fermented meats (salami), and sourdough bread.
These are also utilized for the production of wine and several other beverages.
Recently in the food industry, the use of microorganisms has started on a large scale for the production of chocolate, food color, from preserving fruits, vegetables and meat, and as probiotics which are helpful for human health.
Microorganisms contribute to the smell, texture and taste of the food
For example, bacteria are Lactobacilli that is used for the production of food as these bacteria ferment lactic acid
Lactobacilli are conventionally used to add aroma and texture to the food while preventing the spoilage of dairy products, meat and vegetables as well as silage.
Microorganisms that are present in the GI tract are known for producing health promoting compounds that are called probiotics
These probiotics in fermented products help in the preservation of milk products through the formation of lactic acid which adds to the flavor as well as nutritional value of the food

1. Role of Lactic Acid Bacteria
Lactic acid bacteria are being used in a number of food production and storage methods in the modern food industries.
Lactobacilli are commonly used for the storage of uncooked fermented sausages and sliced meats to avoid pathogenic
These bacteria have replaced the chemical additives such as sodium lactate and potassium acetate which were used for the safety and quality
Mechanism- of action of lactic acid bacteria in raw fermented sausages is the conversion of sugars to lactic acid through fermentation. This contributes to the unfavorable conditions for the growth of pathogenic and spoilage microorganism.

Health promotion and illness risk reduction require functional food components and dietary supplements. The demand for various food products is steadily growing as the world’s population grows. Consumers are becoming more health-conscious in buying nutraceutical and functional food products, and more people are turning to herbal supplements for their health. At the same time, global regulatory authorities are rigorously scrutinizing the quality, safety, and efficacy of nutraceutical components and final products.

2. • Flavour plays a crucial role in our everyday lives and is present in food products, beverages, dietary
supplements, and cosmetics.
• Flavour development is a complex process since it depends on using many ingredients for
developing a product and how our sensory perception of the ingredients provides the overall
flavour experience.
• Artificial flavours have been used for many years since they are relatively more economical.
However, they are associated with adverse effects like allergy, headaches, nausea, and
hyperactivity in children.
• In the long term, artificial flavours can cause kidney and brain damage and respiratory depression.
In addition, artificial flavours are also linked to the causation of certain types of cancers.
• The increasing consumer awareness has led them to seek natural alternatives to artificial flavours.
The shift towards natural flavours

3. M ic r oo r g a ni s ms f or f oo d fl a v our
d e v e l o p m e n t
• Natural flavouring compounds in food, beverages and dietary
supplements are used from plant extracts like plant essential oils.
Sourcing from plants may be resource and time-intensive.
• Biotechnological advances have made it possible to synthesise
flavour even more economically using enzymes. Microorganisms
are relatively easy to culture and can produce flavours de novo. The
subsequent section will elaborate on the mechanism of food flavour
development.
Contd...
4. Mechanism of microorganisms for food
flavour development
Microorganisms contribute to flavour development by the following
mechanisms
FERMENTATION
• Microorganisms such as bacteria and yeast are frequently used in
fermentation to convert ingredients into finished product.
• They digest complex carbohydrates, proteins, and lipids into simpler
components, producing a diverse range of flavour compounds as
metabolic by-products.
• Lactic acid bacteria, for example, convert lactose into lactic acid during
the fermentation of dairy products such as yoghurt and cheese, which
gives rise to the tangy flavour.
Contd...
5.
6. DEVELOPMENT OF VOLATILE FLAVOUR COMPOUNDS
• During their metabolic processes, microorganisms can produce volatile compounds like esters,
aldehydes, and ketones.
• For example, yeasts contribute to the distinct flavour of bread and alcoholic beverages.
Contd...
7. BIOCONVERSION
• Microorganisms facilitate the conversion of intermediate products or added precursors by a
process called bioconversion.
• An example is the conversion of sesquiterpene valencene, a component of orange oil, into
sesquiterpene nootkatone, an important aroma compound of grapefruit.
Contd...
8. FLAVOUR DEVELOPMENT BY AGEING AND MATURATION PROCESS
• Microorganisms can aid in flavour development during ageing and maturation processes.
• This is especially noticeable in foods such as cured meats, wines, and cheese, where the action of
specific microbes over time results in the production of complex and desirable flavours [1].
9. CONCLUSION
• Advances in biotechnology have led to the innovation in natural
flavour development. Microorganisms have been widely studied for this
purpose.
• They are simple to grow and can develop flavour development by
various methods that include fermentation, development of volatile
flavour compounds, bioconversion and ageing and maturation
process
10. How the Food Research Lab can help
• We are a team of food scientists and technologists who offer new product development services for food
and beverage start-ups.
• Our global contract R&D facility enables the development of a wide range of food and beverage products
using the most efficient technologies.
