Problems solved by technology

Studies have proved that high doses of BHA, BHT, and TBHQ have carcinogenic effects, so many countries restrict the use of synthetic antioxidants, and the United States and the European Union prohibit the use of synthetic antioxidants

Abstract

The invention discloses a peony seed oil composite natural antioxidant. The composite natural antioxidant is composed of tea polyphenol, a bamboo leaf antioxidant and ascorbyl palmitate according to a mass ratio of (0.5-2.5):(0.5-2.5):1. The tea polyphenol, the bamboo leaf antioxidant and the ascorbyl palmitate are compounded, and obvious synergistic effects are achieved among the three components; and when the three components are added into peony seed oil, the antioxidant effect is obviously higher than that of a pure single component, is superior to that of TBHQ (Tert-Butylhydroquinone), and is obviously higher than that of BHA (ortho-hydroxybenzoic acid), BHT (Butylated Hydroxytoluene) and other natural antioxidants. The composite natural antioxidant disclosed by the invention is green and non-toxic, has excellent thermal stability and obvious antioxidant effects, and can be used for oxidation resistance of the peony seed oil.

Description

technical field [0001] The invention relates to a compound natural antioxidant of peony seed oil. 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 seed oil during stor...
