Question

can rancidity retarded by storing foods away from light

Answer 1

Rancidity is primarily the hydrolysis and auto-oxidation of fats and lipids. The product of these process, such as ketones and aldehydes, are vastly responsible for the foul smell and unpleasant taste of rancid food. 

Factors that influence auto-oxidation of fats include light and and heat, among others, as they accelerate the speed at which the fats present in food act with oxygen. Light provides energy that speeds the oxidation of fat.

Hence it is true that storing foods in dark places can slow the process of food rancidness.

Answer 2

Answer:

Rancidity- it is the complete or incomplete oxidation or hydrolysis of fats and oils when exposed to air, light, moisture or by bacterial action, resulting in unpleasant taste and odour.

Rancidity can be prevented by:-

Storing foods away from light, In the absence of light the oxidation process of fats and oils slows down and thus rancidity is retarded.

Storing foods away from light, In the absence of light the oxidation process of fats and oils slows down and thus rancidity is retarded. Adding antioxidants to foods containing fats and oils.
