The mushroom, Hericium erinaceus, has received attention for its functional properties. Some of those properties may be related to phenolic and flavonoid compounds, which are believed to promote positive health outcomes. The objective of this study was to determine the effect of production system on the phenolic and flavonoid content of the gourmet mushroom, Hericium erinaceus . Mushrooms were grown in an indoor commercial system, on a prepared substrate or in a forest farming system, outdoors, on a wooden log substrate. Concentrations of phenolic compounds were determined using a Folin‐Ciocalteu based assay. Flavonoid concentrations were determined through a sodium borohydride/chloronil based assay. Units are expressed, based on the standard, in gallic acid equivalents (GAE) for phenols, catechin equivalents (CE) for flavonoids, ascorbic acid equivalents for antioxidant capacity. All measurements are adjusted for moisture content and based on 100 g samples. Commercial mushrooms were (34.17 +/− 1.19 mg GAE & 108.95 +/− 6.98 mg CE) significantly less than forest farmed mushrooms that were harvested in the spring (240.61 +/− 12.80 mg GAE & 595.33 +/− 22.03 mg CE) and fall (313.2±16.8 mg GAE & 1162±108 mg CE) of 2011. Data indicates that mushrooms grown in a more ecologically based production system may contain greater concentrations of potentially health promoting compounds. Grant Funding Source : McIntire‐Stennis
