Abstract:

Glycgrrhizauralensis fisch extract, Rosmarinus officinalis extract, tea polyphenol and vitamin E were selected to prepare natural antioxidant compound for edible oil due to their predominant antioxidation contribution to soybean oil. A orthogonal test design was adopted to optimize the formula of the antioxidant compound. According to the range analysis of obtained test results, the contributions of 4 natural antioxidants to antoxidation were ranked in turn as: Rosmarinus officinalis extract > Glycgrrhizauralensis fisch extract > tea polyphenol > vitamin E, and the optimum formula of the natural antioxidant compound was as follows: Rosmarinus officinalis extract 0.08%, tea polyphenol 0.06%, Glycgrrhizauralensis fisch extract 0.08%, and vitamin E 0.01%. The antioxidant capacity of this compound was weaker than that of TBHO but stronger than that of BHA and BHT.

Key words: natural antioxidant compound, antioxidant capacity, edible oil
