Dehydration is a method of food preservation that involves removing water from food to prevent microbial growth. This can be done through various techniques such as sun-drying, oven-drying, or freeze-drying.

Pasteurization is a food preservation method that involves heating food to a high temperature for a short period to kill microorganisms and inactivate enzymes. This process is commonly used for milk and other dairy products.

Freezing is a food preservation technique that involves the use of low temperatures to slow down microbial growth and enzymatic reactions. This process is commonly used for a variety of foods, including fruits, vegetables, and meats.

Curing is a food preservation method that involves the addition of salt or sugar to food to inhibit microbial growth. This process is commonly used for meats, fish, and vegetables.

Fermentation is a food preservation technique that involves the use of beneficial microorganisms to convert food components into desirable products. This process is commonly used for a variety of foods, including yogurt, cheese, bread, and beer.

Modified Atmosphere Packaging (MAP) is a food preservation method that involves the use of controlled atmospheres, such as modified atmosphere packaging (MAP) or vacuum packaging, to inhibit microbial growth.

Irradiation is a food preservation technique that involves the use of irradiation to kill microorganisms and extend the shelf life of food.

The primary role of food additives in food preservation is to prevent microbial growth and extend the shelf life of food products.

High-Pressure Processing (HPP) is a food preservation method that involves the use of high pressure to inactivate microorganisms and enzymes in food.

The main purpose of using starter cultures in food fermentation is to accelerate the fermentation process and ensure the desired characteristics of the fermented product.

Pulsed Electric Field Processing (PEF) is a food preservation technique that involves the use of pulsed electric fields to inactivate microorganisms in food.

The primary role of antioxidants in food preservation is to inhibit oxidation and prevent the deterioration of food products.

Antimicrobial Peptide Technology is a food preservation method that involves the use of antimicrobial peptides to inhibit the growth of microorganisms in food.

The primary role of enzymes in food biotechnology is to accelerate chemical reactions and facilitate the production of desired compounds in food products.

Microbial Fermentation is a food biotechnology technique that involves the use of genetically modified microorganisms to produce food ingredients or additives.
