111. What role temperature plays in food preservation ?


 Food may be preserved for long in a frozen state because neither microbial enzymes in the food can act at low temperatures to cause its spoilage nor at very high temperatures, as enzymes are denatured. Therefore temperature can play a very important role in preservation.
