The invention relates to Chinese wolfberry vinegar rich in
Monacolin K and gamma-
aminobutyric acid and a preparation method thereof. The Chinese wolfberry vinegar is prepared by the following steps of: preparing germinated rice by using glutinous rice, boiling and gelatinizing the germinated rice, cooling the obtained paste, inoculating the cooled paste with
lactic acid bacteria and
monascus, performing acidifying, liquefying and saccharifying at the same time to obtain saccharified mash, adding water into Chinese wolfberry fruits, performing pulping, mixing Chinese wolfberry pulp with the saccharified mash, inoculating the obtained mixture with
saccharomyces cerevisiae, carrying out alcoholic
fermentation, inoculating the fermented material with
acetic acid bacteria, and carrying out liquid deep ventilation
fermentation. In the
germination process of the glutinous rice, the content of gamma-
aminobutyric acid is remarkably increased, and the
aminobutyric acid has the activities of reducing
blood pressure, calming the mind, improving
kidney function and
liver function, promoting long-
term memory, promoting
growth hormone secretion and the like. The germinated rice is fermented by the functional
monascus, so that a large amount of
lovastatin substances can be generated and have the functions of blocking
cholesterol synthesis and regulating blood fat. In addition, the Chinese wolfberry fruits are rich in
lycium barbarum polysaccharides, polyphenols and flavonoids, and have a good
antioxidant effect. The Chinese wolfberry vinegar is red and bright in color, refreshing in taste,outstanding in ester fragrance and mellow in sour feeling.
