Jeff Chilton Presents Ground Breaking Research at ISMS 2016

On June 1st, 2016, Jeff presented his research at the testing program of different medicinal mushroom products. In one example, he highlights reishi to clearly demonstrate the differences in beta-glucans for whole reishi mushrooms and reishi mycelium grown on grain. The results were as follows: The testing results illustrate that residual grain from mycelium products increases […]

Mushroom Growers Newsletter Weighs in on Beta-Glucan Testing

recent peer-reviewed paper from Dr. McCleary titled “Measurement of β-Glucan in Mushrooms and Mycelial Products”.  In it they state the following: A key medicinal compound in mushrooms is 1,3:1,6-β-glucan.
