Jeff Chilton Presents Ground Breaking Research at ISMS 2016

On June 1st, 2016, at the International Society for Mushroom Science Conference in Amsterdam, Jeff presented his groundbreaking beta-glucan research and new testing program for different functional 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

The AOAC Journal, just published a peer-reviewed paper by Dr. Barry 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. It has been found in shiitake, maitake, reishi and other species and has been shown to have anticarcinogenic activity. Without a good test to measure the amount […]
