Answer:
a)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), as well as slowing the oxidation of fats that cause rancidity. Food preservation may also include processes that inhibit visual deterioration, such as the enzymatic browning reaction in apples after they are cut during food preparation.
b)Improper food storage can lead to several problems, including bacteria and mold growth, food spoilage through natural decay, and even food waste, which costs billions of dollars annually worldwide. Below are some of the areas that are affected by improper storing of food.
c)Refrigeration helps in preserving fruits and vegetables by storing at low temperatures to slow down decay and natural metabolic processes. Meat, fish products and precooked foods also have limited life because of enzyme activities, bacteria attack and ageing.
