Embodiment 1

[0060] Example 1 Preparation of rice composite fermentation puree

[0061] 1. Activation of strains: Pick Lactobacillus delbruechiisubsp. Bulgaricus colonies in two loops and inoculate them into a test tube of 100 mL MRS liquid medium, and activate at 35°C for 24 hours.

[0062] 2. Purification of bacterial strains: After gradient dilution of the above-mentioned liquid bacterial strains, 200 μL was inoculated and spread on MRS solid medium plate, and cultured at 35° C. for 48 hours.

[0063] 3. Liquid culture: Take 3 rings of single colonies from the above plate, inoculate them in 100 mL of MRS liquid medium, and activate at 35°C for 48 hours.

[0064] 4. Expanded culture: Take the above liquid test tube with 10% of the inoculum, insert it into 100 mL MRS liquid medium, and cultivate at 37°C for 12 hours. When the bacterial volume reaches 10 8 At CFU / mL, seed liquid was obtained.

[0065] 5. Preparation of fermentation substrate: take 0.05 g of pomegranate fruit extract (10:...

Embodiment 2

[0069] Example 2 Application of Rice Compound Fermented Puree as Cosmetics

[0070] 1. Safety testing of rice compound fermented puree

[0071] Human patch test is mainly used to detect the irritation of final cosmetic products or raw materials. According to the "Hygienic Standard for Cosmetics" (2015), the present disclosure conducts a human closed patch test on the rice composite fermented puree obtained in Example 1, in order to evaluate its potential skin irritation.

[0072] 1. Test object:

[0073] 30 suitable volunteers were selected for this trial, and the age range was 18-60 years old.

Abstract

The disclosure provides a rice composite fermentation product and its preparation method and application, the preparation method comprising: inoculating fermentation bacteria into a fermentation substrate composed of rice, pomegranate fruit extract, Hedyotis diffusa, and water for fermentation and cultivation , and then carry out sterilization treatment to obtain the rice compound fermentation product. The rice compound fermented product prepared by the preparation method has a strong ability to inhibit the activity of tyrosinase, and has good whitening effect and skin feeling.

Description

technical field [0001] The present disclosure relates to the technical field of fermentation, in particular to a rice composite fermentation product and a preparation method and application thereof. Background technique [0002] Rice is a finished product made of rice after cleaning, hulling, milling and finishing. Rice contains nearly 64% of the nutrients in rice and more than 90% of the nutrients needed by the human body. the main food of the people. Rice also has skin care functions, with rice extract as the main component (which is rich in y-oryzanol, rice furfur sterol and proanthocyanidins and other ingredients), mild and safe in nature, has a strong whitening effect, and can replenish the skin's missing moisture , make the skin smooth and delicate, full of elasticity. my country is rich in rice resources, which provides favorable conditions for the development and application of rice. With the rapid development of the rice cultivation industry and the widening of t...
