Problems solved by technology

[0003] At present, there are two main sources of antioxidants: one is synthetic antioxidants, BHT, BHA, TBHQ and other mainstream antioxidants are widely used in the production of food and other industries due to their high antioxidant activity and low price. However, synthetic antioxidants will cause certain hidden dangers to human health, leading to increasing voices of opposition
The second is natural products with antioxidant properties. Due to their wide sources and high safety, they have received great attention. However, traditional natural antioxidants such as VE, VC, etc. Instability and other shortcomings have limited its application, such as VC is unstable and easily oxidized, VE is a fat-soluble vitamin and cannot be excessive in the body
[0006] For a long time, the oil extract of camellia oleifera has been known for its powerful antioxidant properties, but its application is limited due to the poor water solubility of oily substances and the feeling of use.
At the same time, in the production process of camellia oleifera oil extraction, the seed coat of camellia oleifera is hardly used effectively.

Abstract

The invention relates to a camellia oil seed coat extractive as well as a preparation method and application thereof. The preparation method thereof comprises the following steps: carrying out ungrease treatment on camellia oil seed coat; extracting the camellia oil seed coat after ungrease treatment in a solvent to obtain an extracting solution; and carrying out reduced pressure distillation on the extracting solution so as to obtain the camellia oil seed coat extractive. The camellia oil seed coat extractive extracted and obtained in the preparation method has the characteristics of good water solubility, high oxidation resistance and high stability.

Description

technical field [0001] The invention relates to the technical field of natural extracts, in particular to a camellia seed coat extract and its preparation method and application. Background technique [0002] With the development of the theory of free radicals, more and more scientific researchers such as Carocho point out that an important factor that causes aging and pathological changes in organisms is the peroxidation reaction. By taking an appropriate amount of antioxidants, the occurrence of the peroxidation reaction can be slowed down so that Significantly delay aging, the popularity of these ideas has led to the rapid development of the current antioxidant industry. [0003] At present, there are two main sources of antioxidants: one is synthetic antioxidants, BHT, BHA, TBHQ and other mainstream antioxidants are widely used in the production of food and other industries due to their high antioxidant activity and low price. However, synthetic antioxidants will cause ...
