Chemical composition and nutritive value of the cultivated (Agaricus bisporus) and wild mushrooms grown in Turkey

The chemical composition (moisture, ash, protein, fat, total sugars, water soluble vitamins - vitamin B-1, B-2, C, folic acid, pantothenic acid and vitamin PP, and minerals - Zn, Cu, K, Na, Fe, Ca, Cr and P) of cultivated mushrooms (Agaricus bisporus) obtained from three different commercial firms and wild mushrooms grown in Turkey have been determined. Some chemical constituents of the cultivated mushrooms are as follows (as mean values of three different samples; %): moisture 92.43; protein 2.39; total sugars 0.23; fat 0.56; ash 0.76. Mineral contents (ppm) of samples were found to be: Zn 41.23; Cu 7.10; K 1513.61; Na 49.94; Fe 7.90; Ca 30.45; Cr trace; P 923.2. Vitamin contents of samples were (mg/100 g): B-1 0.077; B-2 0.417; folic acid 0.058; C 5.60; pantothenic acid 2.07; PP 5.32. The results for some edible wild mushrooms (Morchella esculanta and Lactarius deliciosus) showed that variation in chemical constituents were mainly dependent on the type of mushroom.
