[Chemical composition of eight edible mushrooms]

A comparative analysis of crude protein, crude ash, phosphorus (P), potassium (K) and calcium (Ca) contents of 57 samples of eight common edible mushroom species was made. The most important protein sources were: Marasmius oreades and Lepista nebularis. Species of the Boletaceae formed an intermediate group, while relatively proteinless species were: Armillariella mellea and Cratarellus cornucopioides. The lowest crude protein content was established in Cantharellus cibarius. The ash contents varied more widely. The greatest P contents were measured in Lepista nebularis and Marasmius oreades but most mushrooms contained 6-7 gP/kg. The analysed mushroom samples contained 30-40 gK/kg dry weight and 0,2-0,3 gCa/kg. These analyses are important from the point of view of the nutritional role of mushrooms.
