The Functional Mushroom Label Problem, and Three Questions That Settle It

Manuel Gonzales, co-founder of Mushroom Compadres, highlights a labeling issue in the functional mushroom market where products labeled under the same species name can contain different materials, with grain-grown mycelium often standing in for dried fruiting bodies. Lab testing has revealed varying beta-glucan and starch levels in these products, with many containing a significant amount of residual grain. The industry's reliance on total polysaccharide figures obscures the true fungal content, leading to confusion for consumers. Gonzales proposes three questions that buyers can ask to differentiate between products: whether it contains fruiting body or mycelium, the beta-glucan figure, and the starch figure.

The functional mushroom market has seen a surge in interest in recent years, with search data showing a significant increase in demand for mushroom-related products. Gonzales emphasizes the importance of defining terms and using accurate metrics to differentiate between products, similar to the plant-based meat category. By asking key questions and focusing on key indicators like beta-glucan and starch levels, consumers can make more informed decisions when purchasing functional mushroom products.
