Nutrient composition of two strains of shiitake mushrooms grown on sweetgum logs soaked in three different solutions |
N. A. DEHKORDI1, H. Legodi, and C. Sabota. (1) Nutrition & Hospitality Management, Alabama A&M University, POBox 639, Normal, AL 35762 The purpose of this study was to analyze and compare the nutrient composition of shiitake mushrooms grown on sweetgum logs inoculated with two different shiitake mycelia/strains (WW44 and WR46) and to compare the nutrient composition of shiitake mushrooms harvested from sweetgum logs soaked in three different soaking solutions of nitrogen, sugar, and regular water. The mushrooms were grown at the Alabama A&M Winfred Thomas Research Station. Proximate analysis was conducted on each sample for the content of the following nutrients: carbohydrates, crude fiber, protein, moisture, fat, ash, magnesium, calcium, zinc, potassium, phosphorus, chromium, iron, copper, sodium, vitamin D, and amino acids. An analysis of variance was done to compare the levels of different nutrients. Shiitake mushrooms from sweetgum logs inoculated with strain WW44 had significantly higher fat, moisture, zinc, potassium, and phosphorus content than mushrooms from WR46 inoculated logs. Mushrooms from logs soaked in a sugar solution and those from nitrogen solution soaked logs had significantly higher magnesium content. Mushrooms from logs soaked in a sugar solution had the highest zinc and potassium content. Mushrooms from logs soaked in regular water had significantly higher carbohydrate content and lower potassium content. Strain WW44 mushrooms had a relatively high nutrient content and mushrooms harvested from the sugar solution soaked sweetgum logs had relatively high levels of more nutrients than mushrooms from logs soaked in regular water and nitrogen solution. Strain types and soaking treatments used to initiate fruiting in sweetgum logs inoculated with shiitake mycelia have an effect on the nutrient content in shiitake mushrooms.
