AI Technical Summary

Technical Problem

The existing camellia fermentation process lacks functional strains from special ecological environment sources, and fails to effectively improve the anti-saccharification and cellular aging effects of Yunnan camellia. The multi-stage fermentation process leads to high production costs and uncontrollable metabolites of compound bacterial strains.

Method used

The Candida railenensis strain Candida scrambled simplified fermentation was used to design a specific biofermentation process, and fermented Yunnan camellia extracted Yunnan camellia fermentation filtrate.

Benefits of technology

The antioxidant, anti-saccharification and anti-aging effects of the Yunnan Camellia fermentation filtrate are improved. The prepared Yunnan Camellia fermentation extract shows significant anti-oxidant, anti-saccharification and anti-aging effects when used in cosmetics, and the process is simple, environmentally friendly and economical.

Abstract

The present invention belongs to the field of microbial technology and discloses a strain of Candida and its application in the fermentation of Yunnan Camellia. Candida was isolated from Yunnan wild edible fungi (white boletus) Candida railenensis )BTN‑HB‑M5, which was deposited in the Guangdong Microbial Culture Collection Center on September 20, 2024, with the deposit number GDMCC No: 65164. The Yunnan Camellia flower fermentation extract can be obtained by using Candida BTN‑HB‑M5 through appropriate culture and collection processes. The overall fermentation process is green and efficient. The Yunnan Camellia flower fermentation extract prepared is obtained by using only Candida ( Candida railenensis The fermented product of Camellia sinensis (Yunnan Camellia) can be used in food and daily chemical products. It maximizes the preservation of the natural active ingredients of Camellia sinensis, without any added ingredients or irritating byproducts, making it suitable for use in daily chemical products. This Camellia sinensis fermented extract has excellent antioxidant, anti-glycation, and anti-aging effects, significantly alleviating skin aging indicators through antioxidant activity, and has great application prospects in the field of daily chemical products.
