Method for co-fermenting red date and coix seed vinegar with high gamma-aminobutyric acid content through combination of monascus, lactic acid bacteria and spore bacteria

Abstract

The invention belongs to the technical field of table vinegar production, and provides a method for co-fermenting red date and coix seed vinegar with high gamma-aminobutyric acid content through combination of monascus, lactic acid bacteria and spore bacteria. The method comprises steps as follows: mixing germinated coix seeds, coix seed bran, enzymatically decomposed red date juice and L-sodium glutamate, and carrying out alcohol fermentation by mixed bacteria of monascus with high yield of GABA, saccharomycetes and lactic acid bacteria; after the fermentation is finished, supplementing sugar, red date juice, L-sodium glutamate, lactic acid bacteria, spore bacteria and acetobacter pasteurianus, and carrying out aerobic acetic acid and lactic acid fermentation; and after the fermentation is finished, adding lactic acid bacteria for anaerobic secondary lactic acid fermentation. The red date and coix seed vinegar with high gamma-aminobutyric acid content is prepared through raw material optimization, strain optimization proportioning, multiple times of fermentation enrichment, ageing, blending, sterilization and filling. In a final product, the content of non-volatile acid is larger than or equal to 2.0 g / 100 mL, the content of flavone is larger than or equal to 120 mg / 100 mL, the content of GABA is larger than or equal to 280.0 mg / 100 mL, the content of Monacolin K is larger than or equal to 120 mg / 100 mL, and the effects of resisting oxidation, lowering cholesterol and lowering blood pressure are achieved.

Description

technical field [0001] The invention belongs to the technical field of vinegar production, and in particular relates to a method for co-fermenting high-γ-aminobutyric acid jujube barley vinegar with monascus, lactic acid bacteria and spores. Background technique [0002] Jujube is a rare food with the same origin of medicine and food that is loved by people. Its vitamin content is very high, and it has the reputation of "natural vitamin pill". Compounds and cyclic adenosine monophosphate have the function of inhibiting the growth and reproduction of cancer cells; the rich flavonoid compound ‒ rutin can maintain the normal resistance of capillaries, reduce permeability, and reduce fragility, and can prevent capillary hair loss. Hemorrhagic disease caused by brittleness, used for diseases such as hypertension, thrombocytopenia and sepsis; the polysaccharide contained is an important physiologically active substance, which has obvious anti-complement activity and promotes lymph...

Problems solved by technology

However, there is no follow-up measurement on the GABA enrichment effect in the fermentation process from raw materials to the final product; there is even a lack of fermentation research experiments on GABA enrichment such as strain optimization, combination ratio, and combination method; resulting in long fermentation time and low enrichment efficiency. low level problem

In addition, the fermentation raw materials are single, mainly brown rice and millet, resulting in monotonous product flavor and lack of layering
