AI Technical Summary

Technical Problem

Few research and products in the prior art involve fermented white tea, resulting in insufficient application in the field of plant cosmetics production, especially in obtaining high content of polyphenols and total flavonoids.

Method used

The white tea extract was obtained by ultrasonic extraction with airflow ultrasonic solution and aqueous butylene glycol, and fermented with Ganoderma lucidum seed liquid and liquid culture medium in a preferred ratio to prepare a white tea fermentation filtrate containing more polyphenols and total flavonoids.

Benefits of technology

It has achieved a significant increase in polyphenols and total flavonoids in the white tea fermentation filtrate, which has improved its antioxidant, anti-wrinkle and anti-photoaging effects, and provided better skin care effects, such as moisturizing, wrinkle removal and barrier repair.

Abstract

The invention relates to a preparation method of a white tea fermentation filtrate, a white tea fermentation filtrate product and a preparation method. The preparation method sequentially comprises the following steps: (1) obtaining a white tea extract; (2) obtaining a ganoderma lucidum seed solution; (3) obtaining a white tea fermentation product: sterilizing and cooling the white tea extract liquid obtained in the step (1), uniformly mixing the white tea extract liquid with the ganoderma lucidum seed liquid obtained in the step (2) and the liquid culture medium obtained in the step (2) according to the volume ratio of (800-1000): (10-100): (20-100), and fermenting for 48-96 hours under the conditions that the temperature is 30-40 DEG C and the pH value is 5.0-7.0; and (4) obtaining white tea fermentation filtrate. The method overcomes the defects that related reports for researching fermented white tea exist in the market and more products of the fermented white tea exist, and the white tea extract prepared by adopting optimal preparation steps and technological parameters, the ganoderma lucidum seed liquid and the liquid culture medium are fermented according to an optimal proportion, so that the white tea with more polyphenol, total flavonoids and the like can be obtained. The white tea fermentation filtrate has the advantages of excellent oxidation resistance, wrinkle resistance and light aging resistance.
