This study was undertaken to investigate the rancidity of various frying oils from fried snack shops.
The Results obtained were as follows;
1) Free fatty acid contents of 3 sample frying oils of 6 sample frying oil tested were more then A.V 5, and all frying oils used in frying were more than legal standard contents of free fatty acids.
2) all frying oils tended to encrease in the Iodine Value and Iodine values of 3 sample frying oils were more than 90.
3) all fryins oils tended to increase in the viscosity and mean molecular waight of frying oil owing to polymerization of various radicals each other.
4) It was assumed that alcohols, Carbonyl, Compounds besides polymers of frying oil existed in the Diethyl ether fraction from investigation of I. R-Spectrum for Dietly1 ether-fraction.
5) Various frying oils was generally tended to increase in the Free fatty acid contents comparable to fresh oil.
