What is Black Yeast Beta-Glucan?
Aureobasidium (black yeast)
What is β-glucan?
Aureobasidium (black yeast) β-glucan is a member of dietary fiber, a type of polysaccharide. There are substances on the cell wall such as yeast and filamentous fungi and β-glucans contained in mushrooms (agaricus, ganoderma, etc.). “Aureobasidium (black yeast) β-glucan” introduced here is obtained from black yeast (academic name: Aureobasidium). When black yeast is cultured under special conditions, gel-like substances are produced. It contains a lot of good quality β – glucans in its gel-like liquid.
In addition, the black yeast (Aureobasidium) culture broth was officially announced as “Ministry of Health and Welfare (current Ministry of Health, Labor and Welfare Notification No. 120)” in the Official Gazette issued by the Ministry of Finance on April 16, 1996 .
