CHEMICAL AND SENSORIAL ANALYSIS OF PLEUROTUS OSTREATUS CULTIVATED ON COCONUT (COCOS NUCIFERA LINN.) HUSK SUPPLEMENTED WITH WHEAT AND/OR RICE BRAN

ABSTRACT

An assay on cultivatedmushrooms (Pleurotus ostreatus) was carried out on coconut bark ground with 0, 20 and 40% supplementation of rice and/or wheat bran. The samples obtained from the crops were frozen and dehydrated, and submitted to chemical and sensorial analysis. Protein levels ranged from 8.33 to 19.98%. Ashes ranged from 5.5 to 9.7% and lipid content was 0.23 to 4.4%. The average iron content was 15.53mg/100 g, and ascorbic acid ranged from 24.28 to 27.61 mg/ 100 g. The chemical composition was influenced by the supplementation and by the isolates tested. The acceptance of the mushrooms in regard to flavor and appearance was influenced by the type of substratum and the isolates tested.
