Abstract

The invention discloses a liquid oil-instant and stable rosemary antioxidant and a preparation method thereof. In the method, the rosemary material is adopted as raw material, edible oil is adopted as a carrier cosolvent to assist the supercritical carbon dioxide to strengthen and selectively extract the oxidation resistance active ingredients in the rosemary material, and then the liquid oil-instant and stable rosemary antioxidant and the rosemary essence oil are prepared by one step. The liquid oil-instant and stable rosemary antioxidant can be instant, stable, safe and highly-efficient, and can be directly used for edible oil, foods, health products, medicines, cosmetics and the like. The prepared rosemary essence oil can be directly used as natural perfumes.

Description

technical field [0001] The invention relates to a liquid oil instant and stable rosemary antioxidant and a preparation method thereof. Background technique [0002] Rosemary, native to Europe, is now planted on a large scale in Guizhou, Hunan, Guangxi and other places in my country. The active ingredients - rosemary essential oil and antioxidants - can be extracted from the leaves, flowers and other parts of the plant. Rosemary antioxidants can be divided into two categories: oil-soluble and water-soluble. The active ingredients of oil-soluble antioxidants are mainly terpene phenols such as carnosic acid and carnosol, which are used in animal and vegetable oils, dairy products, oil-rich foods, candies and baked goods, etc., because of their good thermal stability, they can be High temperature resistance of 190°C to 240°C, so it has strong applicability in foods that require higher temperature or high temperature sterilization during the processing of baked food, fried food...
