Abstract

The invention discloses a paeonol-containing peony seed oil composite natural antioxidant. The composite natural antioxidant consists of tea polyphenols, paeonol and ascorbyl palmitate in a mass ratio of (0.5-2.5):(0.5-1.5) :1 composition. In the present invention, by compounding tea polyphenols, paeonol and ascorbyl palmitate, there is an obvious synergistic promotion effect between the three, and the anti-oxidation effect added to peony seed oil is significantly higher than that of the pure single component, and the anti-oxidation The effect is better than TBHQ, significantly higher than BHA, BHT and other natural antioxidants. The compound natural antioxidant of the invention is green and non-toxic, has good thermal stability and remarkable antioxidation effect, and can be used for antioxidation of 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...
