Abstract

Rancidity is the process which causes a substance to have unpleasant smell or taste. It is a biochemical reaction between fats and oxygen which causes oxidation of fats turning the substance rancid. There are three types of rancidity namely oxidative, ketonic, and hydrolytic rancidity. Consuming rancid substances may be slightly toxic and the harmful free radicals may cause cellular damage and digestive distress. In this analysis 30 samples were collected from different stores of KalyanTaluka and studied for oxidative rancidity using method prescribed by International Fragrance Association IFRA. The result showed oxidative rancidity values for 30 oil samples were between 0.11 to 1.66 mEq/Kg range which is considered under the lower oxidative rancidity range i.e.<10mEq/Kg. Mustard oil showed highest mean peroxide value i.e. 1.028 mEq/Kg followed by sunflower oil with 0.636 mEq/Kg. where as palm oil and Castor oil showed least peroxide values which was 0.13 mEq/ Kg. This study concluded that all oil samples collected from KalyanTaluka were less rancid and within permissible limit.
