German researchers Miriam Sari and Jan Lelley have recently published a new research paper in the Journal of Food Chemistry entitled “Screening of beta-glucan contents in commercially cultivated and wild growing mushrooms“. This paper looks at the beta-glucan content in commercially grown and wild mushrooms. Where possible they also looked at the beta-glucan content in the […]
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 […]
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 […]
A newly published research paper in the peer-reviewed Journal of American Association of Agricultural Chemists, AOAC, the organization that sets and validates the testing standards for all analytical testing, confirmed the findings in Jeff’s Redefining Medicinal Mushrooms, and validated the Megazyme method for beta-glucan testing. The paper is titled “Measurement of β-Glucan in Mushrooms and […]
A recent article at Total Health Magazine, entitled “What’s In Your Medicinal Mushrooms?”, by Dallas Clouatre, PhD, highlighted quality control issues in the supplement market. In it, Dr. Clouatre discusses the current issues facing the medicinal mushroom industry such as product adulteration and product mislabelling.
My recent guest contribution to HerbalGram (American Botanical Council), “Commercial Labeling of Medicinal Mushroom Products”, reveals how U.S. myceliated grain products are being sold as “mushroom”. These grainy products are not mushrooms, but actually a food product called Tempeh, yet they are being sold as mushroom supplements.
