Abstract: The present invention provides a method for producing ?-aminobutyric acid by fermenting a rice medium from the preparation of a Cordyceps species and the application thereof. Firstly, water and an appropriate amount of rice medium are mixed together to form a fermentation broth. Secondly, add lactic acid bacteria to the fermentation broth. Then, the fermentation broth is fermented by both of the Cordyceps species retained in the rice medium and the lactic acid bacteria. Consequently, the ?-aminobutyric acid is produced. Moreover, the fermentation broth prepared by this method can be applied to a health food or drink.

Abstract: The present invention provides an isolated Saccharomyces pastorianus No 54, which is found to be effective in regulating blood glucose levels and fat or its related disease. Therefore, not only could it control the high blood sugar levels in type 1 diabetic patients, but also it would help to control both of the high blood glucose levels and fat of type 2 diabetic patients.

Abstract: The present invention relates to chrome-free fermentation products, which are obtained by the fermentation of Saccharomyces cerevisiae. The fermentation products of the invention may effectively control the level of blood sugar, and useful to improve the normal metabolism of glucose and increase glucose tolerance when administered to non-insulin-dependent diabetes (NIDD) patients.
