Abstract

The invention provides a method for controlling monascus to produce a monascus pigment by utilizing tea polyphenols. The method comprises the following steps of strain activation, seed liquid preparation and fermentation, wherein tea polyphenols are added to a fermentation medium. The pigment production in a fermentation broth can be obviously improved by adding the tea polyphenols, and the content of citrinin is not increased.

Description

technical field [0001] The invention belongs to the field of microbial fermentation, and more specifically, the invention relates to a method for using tea polyphenols to regulate the pigment production of Monascus. Background technique [0002] Monascus is a small filamentous saprophytic fungus, which can produce secondary metabolites with physiological activity during the fermentation process, including monascus pigment, lovastatin compounds (Monacolin K), γ-aminobutyric acid ( GABA), ergosterol, bioflavonoids, etc., have many health benefits. The most unique and functionally rich component among these secondary metabolites is monascus pigment. It has bright colors and strong ability to color proteins. A large number of research data show that Monascus pigment has physiological activities such as antibacterial and antiseptic, anti-oxidation, anti-inflammation, lowering blood fat, regulating blood sugar, and preventing arteriosclerosis. [0003] Tea polyphenols, also know...
