Peony seed oil compound natural antioxidant containing rosemary extract

Abstract

The invention discloses a peony seed oil compound natural antioxidant containing rosemary extract. The compound natural antioxidant is prepared from tea polyphenol, rosemary extract and ascorbyl palmitate in a mass ratio of (0.5-2.5): (1-3): 1. By compounding the tea polyphenol, rosemary extract and ascorbyl palmitate, an obvious synergistically facilitating effect is generated among the three, and the mixture is added into the rosemary extract, so that the antioxidant effect is remarkably higher than that of a pure single component, and the antioxidant effect is superior to that of TBHQ as well as BHA, BHT and other natural oxidants. The compound natural antioxidant disclosed by the invention is green and non-toxic, has good heat stability and a remarkable antioxidant effect 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 containing rosemary extract. 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 o...

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
