| With refined high oleic acid rapeseed oil as the base oil, the special oil for frying was developed and a reasonable frying oil formula was designed. According to the frying characteristics, fatty acid composition and quality requirements of the common frying oils such as palm oil, cottonseed oil and high oleic acid rapeseed oil, formula oil with oleic acid content higher than 45%, linolenic acid content less than 4% and polyunsaturated fatty acid content less than 30%was obtained. Through the equation calculation and preliminary experiment, the optimal formula was obtained as follows: mass ratio range of high oleic acid rapeseed oil to 24?℃ palm oil to cottonseed oil 50%- 64%∶?0% - 36%∶?0% - 24%. Five kinds of formula oils were screened by computer, among which formula oil 5(mass ratio of high oleic acid rapeseed oil to 24?℃ palm oil 64∶?36) had good frying stability, long frying life and good sensory effect on fried foods, so it was a good choice for frying formula oil. |
