Yellow rice wine rancidity was induced mainly by lactobacillus fermentation.
The more unsaturated fatty acids (double bonds) the more susceptible the fat is to rancidity.
BHT also prevents oxidative rancidity of fats. It is used to preserve food odor, color, and flavor.
The nutritional function of oil, mechanism of oxidative rancidity, the effects of oxidized oil on animals, and oil oxidation prevention and control measures were discussed.
While it's understandable that many people have learned to enjoy off flavors in oils, there's a good reason to recognize staleness and rancidity for what they are and avoid them.
Compared with the control, the vacuum package or adding deoxidant package with materials of low venting quality can constrain the accelerating speed of PV and AV, and delay rancidity.
An example of irradiation causing an obvious chemical change in food is the inducement of rancidity in foods containing unsaturated fats when oxygen is present. The process is closely related to that which normally takes place when such foods are stored.
