The invention discloses a preparation method of cheddar cheese rich in gamma-
aminobutyric acid. The cheddar cheese comprises the following raw materials of
raw milk,
chymosin,
calcium chloride, a fermenting agent and the like. The cheddar cheese rich in gamma-
aminobutyric acid is made through the working procedures of
standardization of the
raw milk, sterilization, cooling, innoculating
streptococcus thermophilus and a commercial direct-vat type fermenting agent, generating acid, adding the
calcium chloride, adding the
chymosin for obtaining milk curds,
cutting the milk curds, cheddaring, crushing the milk curds,
salting, and maturing. The gamma-
aminobutyric acid has the effects of regulating the
blood pressure, stimulating the
insulin secretion, restraining
arteriosclerosis, improving the functions of the liver and the
kidney, activating
cerebral metabolism, calming and the like. According to the preparation method disclosed by the invention, the
streptococcus thermophilus and the commercial direct-vat type fermenting agent are compounded, so that the content of the gamma-aminobutyric acid is continuously accumulated in the making and maturing stage of the cheese, and the content of the gamma-aminobutyric acid in the cheddar cheese is 10-100mg / 100g. The cheese not only reserves the
nutrient value, but also increases the
physiology efficacies of the gamma-aminobutyric acid, so that the added value of products is increased.
