Problems solved by technology

These studies are mainly aimed at the yield of total polyphenols (determined by Folin method), and there is no solvent selection and condition optimization with avenanthramide as the target.
And from the study of extraction methods, there is a common problem that emphasis is placed on yield and purity is underestimated.

Abstract

The invention relates to an avenanthramide extract as well as an extraction method and application thereof. The extraction method of the avenanthramide extract comprises the following steps of pretreating oat, performing oat germination, performing treatment on germinated oat, performing ultrasonic extraction, performing purification and the like. Avenanthramide is enriched through germination promoted with cinnamic acid, the effect is notable, the avenanthramide extract in which the content of the avenanthramide is 6.7-13.3% can be obtained, a useful way is provided for efficient enrichment of a natural antioxidant, the avenanthramide has favorable oxidation-resisting effect in edible oil, an advisable antioxidant source is increased for the edible oil industry and economic benefits are considerable.

Description

【Technical field】 [0001] The invention belongs to the technical field of processing and application of cereal functional components. More specifically, the present invention relates to a kind of oat anthramid extract, also relate to the extraction method of described oat anthraamide extract, also relate to the purposes of described oat anthraamide extract. 【Background technique】 [0002] Oats belong to the family Poaceae. Oats are annual herbaceous plants. According to the characteristics of lemma, they can be divided into two types: lemma type and naked type. The oats planted in my country are mainly naked oats. At present, there are three main consumption forms of oats: (1) pure oat products: oat flakes, oat flour, diced oats, etc.; (2) processed oat products: instant oatmeal, oat bread, oat biscuits, oat drinks, etc.; (3) Oat functional food: bioactive substances extracted from oats such as β-glucan products, etc. For details, see Zhou Sumei, Shen Ruiling, "Nutrition and...
