Green phenol koji with whitening function and preparation method thereof

Abstract

The invention discloses a green phenol koji with whitening function and a preparation method thereof, the preparation method comprises the following steps: S1, selecting mung bean leaves, mung bean flowers and mung bean seeds, drying and crushing the mung bean leaves and the mung bean flowers, drying and grinding the mung bean seeds, and mixing the crushed mung bean leaves, the crushed mung bean flowers and the ground mung bean seeds in equal mass; S2, mixing lactic acid bacteria powder and bifidobacterium powder according to an equal ratio, dissolving the mixture in purified water to obtain mixed strain fermentation liquor, spraying the mixed strain fermentation liquor into the mixture obtained in the step S1 in layers, and ferment in a fermentation chamber for 3-5 days; S3, mixing the fermented mixture of the step S2 with ethanol according to the solid-liquid ratio of 1: (12-15) (g / ml) and extracting for 1-2 hours at the temperature of 45-50 DEG C, and the volume fraction of the ethanol is 55-60%; and S4, evaporating and concentrating the extracted liquid obtained in S3 to 1 / 3-1 / 5 of the volume at 45-55 DEG C, and freeze-drying the concentrated liquid to obtain the green phenol koji. The mung bean leaves, mung bean flowers and mung bean seeds are used as preparation raw materials, the utilization rate of the raw materials is improved, and the yield of the mung bean koji is improved by adopting a first-fermentation and second-extraction technology.

Description

Technical field [0001] The present invention relates to the field of skin care technology, and more particularly to a green phenolic curvature having a whitening function and a preparation method thereof. Background technique [0002] Mung beans are also known as green beans, soybeans and beans. It is a cultivation species of the bean butterflyfettum subcivil cuisine beans plant. In my country has been cultivated for more than 2,000 years of cultivation, most of the country is planting. Yield is rich. In addition to the human body necessary nutrient protein, fat, amino acids, and vitamins containing the human body, there are many biologically active ingredients, such as tannins, coumarin, alkaloids, polysaccharides, saponins, and phytosterols, such as these active substances and mung beans Care and pharmacological effects such as blood lipids, antioxidants, anti-tumor and detoxification. [0003] Mung beans have a high medicinal value and good health function, but the machining o...

Problems solved by technology

However, the existing technology only uses mung bean seeds as raw materials to extract phenolic substances, resulting in waste of resources

Moreover, the soaking method is often used to extract the phenolic positions in mung beans, which not only has a low extraction amount and takes a long time, but also has a complicated extraction process, which is not convenient for large-scale production
