Title:
LOW-IRRITATION γ-AMINOBUTYRIC ACID PRODUCT, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF FOR REDUCING IRRITATION
Document Type and Number:
WIPO Patent Application WO/2023/125330
Kind Code:
A1
Abstract:
Provided is a type of Saccharomyces cerevisiae, the preservation number thereof being CCTCC NO: M20211621. Further provided is a preparation method for a low-irritation γ-aminobutyric acid product. The preparation method comprises the following steps: inoculating yeast into a solution containing γ-aminobutyric acid and fermenting; upon completion of fermentation, crushing and filtering microorganism bodies in the fermentation liquid to obtain a filtrate containing γ-aminobutyric acid; and further adding an additive into the filtrate and spray drying to obtain a low-irritation γ-aminobutyric acid composition. It has been discovered by the present invention that a stabbing pain of γ-aminobutyric acid may be partially caused by impurities in a γ-aminobutyric acid product, and by means of a production process of the present invention, some irritating impurities can be consumed, and a soothing component can also be generated, thereby reducing discomfort caused by γ-aminobutyric acid.
