Abstract

The invention discloses a preparation method for black soyabean seed coat anthocryanin, which comprises following steps: 1. peeling the black soyabean seed coat as material; 2. smashing the seed coat into fine with micronizer to treat with microwave machine; 3. using 60~80% ethanol solvent to leach the said anthocryanin; 4. condensing the said condensing liquid in vacuum till the concentration of solid in extract liquid more than 40%; 5. degreasing, absorbing with macropore resin and desorbing with 65~75% ethanol, and obtaining the purified extract liquid; 6. repeating the vacuum condensation till the concentration of solid in extract liquid more than 60%, and freeze drying to obtain the objective product with well stability. This invention is simple.

Description

technical field [0001] The invention relates to a method for preparing black soybean seed coat anthocyanins. Background technique [0002] Black soybean is one of the traditional medicinal and edible agricultural resources. Since ancient times, folks have recorded that black soybean has been used to nourish blood, promote blood circulation and blacken hair, which suggests that black soybean has high research value and development potential. Modern nutritional research has further found that natural anthocyanins in black food have strong anti-active oxygen damage and anti-oxidation effects, can eliminate excessive free radicals produced during the body's metabolism, and can delay aging and prevent various diseases. and other functions. Black soybean seed coat is rich in anthocyanins, which is an important source of natural pigments. Predecessors have done a lot of research on the chemical structure and stability of black soybean seed coat pigment, see Xiao Xiang et al. Blac...
