preservation. Mention the food that can be preserved using those techniques
Answers
Answer:
Food preservation prevents the growth of microorganisms (such as yeasts), or other microorganisms (although some methods work by introducing benign bacteria or fungi to the food), and slowing the oxidation of fats that cause rancidity.
Physical methods of food preservation include dehydration, refrigeration and freezing, controlled atmosphere storage, modified atmosphere packaging, vacuum packaging, various forms of heat treatment, ultraviolet radiation, ionizing radiation and high hydrostatic pressure (Farkas, 1997).
Among the oldest methods of preservation are drying, refrigeration, and fermentation. Modern methods include canning, pasteurization, freezing, irradiation, and the addition of chemicals. Advances in packaging materials have played an important role in modern food preservation.
