Abstract

The invention discloses a preparation method of a compound containing mulberry anthocyan. The preparation method comprises the following steps of mixing partly-acylate konjac glucomannan with the mulberry anthocyan in a certain proportion to obtain a mulberry anthocyan compound product, wherein in the mulberry anthocyan compound product, the weight ratio of the partly-acylate konjac glucomannan tothe mulberry anthocyan is (20 to 1) to (400 to 1). According to the preparation method of the compound containing mulberry anthocyan, fade of the mulberry anthocyan caused by being too hot is effectively restrained, and the stability of the mulberry anthocyan is greatly improved; and color of the compound containing mulberry anthocyan is enriched and increased, and the preparation method has excellent application value. The preparation method is simple and convenient, easy to operate, safe, and environmental-friendly, and realization of industrial enlarged application is facilitated.

Description

technical field [0001] The invention relates to the technical field of natural pigments, in particular to a preparation method of a compound containing mulberry anthocyanins. Background technique [0002] Mulberry is the mature fruit of the mulberry tree. It is bright in color and rich in nutrition, and is very popular among consumers. my country has a large area of ​​mulberry tree planting, rich mulberry varieties, and its output ranks first in the world. Modern research shows that mature mulberries are rich in anthocyanins, mainly cyanidin-3-O-glucoside and cyanidin-3-O-rutinoside. Anthocyanins in mulberry have small molecular weight, simple structure and easy absorption, and are a good source of natural pigments. The color of mulberry anthocyanins will vary depending on the environment, and can provide a variety of color changes. And mulberry anthocyanins have a strong ability to scavenge free radicals, which can resist oxidation, inhibit cardiovascular diseases, and d...
