Abstract

The invention discloses an antioxidant health rice bran oil, which comprises the following raw materials by weight: 50-70 parts of rice bran oil, 10-20 parts of camellia oil, 10-20 parts of canola oil, 3-6 parts of Chinese wolfberry, 5-10 parts of garlic, 6-9 parts of licorice, 3-5 parts of a ginkgo leaf extract, 2-4 parts of a rhodiola extract, 3-6 parts of a herba epimedii extract, 5-9 parts of grape seed, 3-9 parts of walnut kernel, 3-5 parts of Schisandra chinensis, 5-9 parts of peanut, and 6-10 parts of pinenut kernel. The invention also discloses a preparation method of the antioxidant health rice bran oil. The method includes the steps of: S1. Chinese wolfberry pretreatment; S2. garlic pretreatment; S3. licorice pretreatment; S4. squeezing oil making; and S5. mixing. The antioxidant health rice bran oil provided by the invention has strong antioxidant capacity, can delay aging, reduce blood fat, balance nutrition and enhance body immunity, and has the characteristics of health care, simple operation, good antioxidant effect, and an average DPPH free radical scavenging rate up to 99.69%.

Description

technical field [0001] The invention relates to the technical field of oils and fats, in particular to an antioxidant health-care rice bran oil and a preparation method thereof. Background technique [0002] Rice bran oil is rich in unsaturated fatty acids, mainly oleic acid and linoleic acid, and the ratio of the two is close to 1:1. It is called "healthy nutritional oil" abroad. Rice bran oil also contains some special active ingredients, such as oryzanol, tocopherol, squalene, sterol, etc. There will be no allergic reaction when eating rice bran oil. Rice bran oil can increase the content of high-density cholesterol protein and reduce the content of low-density cholesterol lipoprotein. [0003] At present, the process of refining rice bran oil in my country is not perfect. When storing rice bran, a large amount of unsaturated fatty acids will be decomposed; when refining rice bran oil, a large amount of active ingredients such as oryzanol, tocopherol, squalene, and stero...
