What is beta-glucan


Aureo's black yeast beta-glucan


Black yeast beta-glucan is categorized as dietary fiber and a type of polysaccharide. Beta-glucan is present in the cell wall of yeasts and filamentous fungi, as well as in mushrooms (Agaricus sp., Ganoderma lucidum, etc.). The black yeast beta-glucan described here is obtained from black yeast (Latin name: Aureobasidium pullulans).
If black yeast is cultured under special conditions it forms a gel. The gel is rich in quality beta-glucan. Aureobasidium (black yeast) cultured solution was officially given food additive status in Notification No. 120, Ministry of Health and Welfare of Japan 1 (current Ministry of Health, Labour and Welfare)1 on April 16, 1996. (The notification was published in the gazette issued by the Ministry of Finance of Japan.)
