Abstract

The invention belongs to the technical field of pigment extraction, and particularly relates to a method for extracting haematochrome from mulberry red. The method comprises the following steps of (1) preprocessing; (2) preparing a separating medium through a freezing wall-breaking method; (3) extracting an extracting solution through distilled water; (4) degumming through an enzymic method; and (5) recycling haematochrome through distilling. The method has the beneficial effects that natural biological activity pigment component in the mulberry pulp is furthest reserved due to the freezing wall-breaking method, and the natural edible haematochrome prepared by the method has strong water solubility, is amaranth, reserves maximum nutritional ingredients of the mulberry, and can be used in food, beverage, cosmetics and the like.

Description

technical field [0001] The invention belongs to the technical field of pigment extraction, and in particular relates to a method for extracting red pigment from mulberries. Background technique [0002] Mulberry is the near-ripe flowering fruit of the Moraceae Morus plant mulberry, common things mulberry jujube, mulberry, and mulberry is the mature ear of the perennial deciduous tree mulberry tree of the family Moraceae. Mulberry is not only delicious, but also has many health care functions. Since ancient times, mulberry has been used Used as Chinese herbal medicine. There are records in "Shen Nong's Materia Medica", "Compendium of Materia Medica" and other books, and it is believed that mulberry "relieves thirst, sharpens the five internal organs and joints, clears the blood, keeps people hungry after long-term use, makes people smart, black and not old..."; , detoxification of alcohol poisoning, wine brewing, diuresis and swelling"; "beneficial ...
