Recombinant antifreeze proteins and fermentation are the methods of food preservation that are examples of biotechnology.

Pasteurization is a process in which pathogenic microorganisms are destroyed or killed in certain foods and beverages by providing specific amount of heat.

The main advantages of Fermentation is that it helps to break down nutrients that is present in food, make it easier to digest than unfermented food substances.

The cheese making process consist of six important steps i.e. acidification, coagulation, separating curds, salting, shaping, and ripening.

Yeast uses the sugars and oxygen that is present in dough in order to produce more yeast cells which releases more carbon dioxide gas. The carbon dioxide cause rise in the dough which gives the bread a light and spongy texture.

Different food preservation methods develop in different regions of the world because the environment as well as different types of pathogens are present which needs different method for its removal.
