Abstract

The invention discloses a peony seed oil composite natural antioxidant containing paeonol. The composite natural antioxidant is prepared from tea polyphenol, paeonol and O-palmitoyl-L-ascorbic acid in the mass ratio of (0.5-2.5):(0.5-1.5):1. According to the antioxidant, tea polyphenol, paeonol and O-palmitoyl-L-ascorbic acid are compounded, an obvious synergistic effect is generated among the three components, and the antioxidant effect is remarkably higher than that of a pure single component after the three components are added into peony seed oil; the anti-oxidation effect is better than that of TBHQ and obviously higher than that of BHT, BHT and other natural antioxidants. The composite natural antioxidant is environmentally friendly, free of toxins, good in heat stability, remarkable in antioxidant effect and capable of being used for resisting oxidation of the peony seed oil.

Description

technical field [0001] The invention relates to a compound natural antioxidant of peony seed oil containing paeonol. Background technique [0002] Peony seed oil is rich in unsaturated fatty acids, its content is as high as more than 90%, polyunsaturated fatty acid α-linolenic acid exceeds 40%, and its nutritional value far exceeds that of olive oil, tea seed oil, and walnut oil. Therefore, peony seed oil was approved by the Ministry of Health as a new energy food in 2011, which is of great significance for vigorously developing woody oil crops and solving the grain and oil crisis in my country. However, due to its high degree of unsaturation, it is easily oxidized by factors such as light, heat, oxygen, and moisture during long-term storage, and produces peroxides, aldehydes, ketones and other compounds, resulting in discoloration and taste of oils and fats, reducing edible value. It can even endanger your health. In order to inhibit the oxidative deterioration of peony s...
