Abstract: The present invention relates to a method of manufacturing fermented soybeans having increased gamma-aminobutyric acid (GABA) content, and more particularly, a method of manufacturing fermented soybeans having increased gamma-aminobutyric acid content which comprises the steps of: adding lactobacillus having glutamate decarboxylase (GAD) activity and glutamate (MSG) to soybeans; grinding and molding the mixture; and spraying starch powder mixed with seed malt onto the surface of the molded mixture. The present invention can provide a method of manufacturing fermented soybeans including GABA, which has been known to accelerate sodium ion discharge through urine, so that it may lower blood pressure hypertension which may be caused from excessive consumption of salts to prevent and can produce functional paste foods satisfying people's taste and desire for health.

Abstract: The present invention relates to a medium composition comprising fermented Korean hot pepper paste, undiluted solution of brewed soy sauce or acid hydrolyzed soy sauce, and a method for producing gamma-aminobutyric acid (GABA) using the medium. More precisely, the present invention relates to a medium composition for culturing lactobacillus having GAD activity, the composition comprising fermented hot pepper paste, brewed soy sauce or acid hydrolyzed soy sauce, and a method for producing a high concentration of gamma-aminobutyric acid from the medium additionally added with glutamic acid or glutamate. The present invention provides a method of producing a high concentration of gamma-aminobutyric acid using the above medium with low production costs. Since the by-products of pastes are used as medium compositions, this medium itself can be added to other pastes or foods to produce functional foods containing gamma-aminobutyric acid.

Abstract: A method for producing a koji of a hot pepper paste with reduced capsaicin and/or dihydrocapsaicin content through action of enzymes secreted from a koji fungus includes adding a koji fungus to starting material for preparation of koji of hot pepper paste, and adding a predetermined amount of hot peppers one or more times to the material during the cultivating step performed by enzymes secreted from the koji fungus. The method can reduce the hotness of a hot pepper paste, while maintaining the intrinsic colors of traditional hot pepper pastes. Accordingly, it is possible to prepare various hot pepper paste products satisfying customer's diverse needs.
