On the other hand, methods for preventing oxidation of lipid components include freezing or refrigeration, vacuum packaging, gas replacement packaging, oxygen absorber-encapsulated packaging, and addition of antioxidants. Oxidation of lipid components causes changes in odor, color change, destruction of vitamins, and denaturation of proteins, so preventing oxidation of lipid components is extremely important to maintain quality and nutritional value. As mentioned above, there are various ways to prevent the oxidation of lipid components.
A simple and effective method is to use antioxidants. Various antioxidants are used, but
The antioxidant effect itself, the sustainability of the effect, and the effects on color and odor were not fully satisfactory from a comprehensive standpoint.
