Influence of pileus size on composition of biochemical parameters in milky mushrooms

Abstract

Calocybe indica, known as milky white mushroom is tropical in origin and is gaining commercial importance in Telangana state due to their nutritional, antioxidant and therapeutic values. In Telangana the market for the fresh mushrooms of Calocybe spp. is mainly based on the size of the pileus of mushroom. Keeping this in view the present study was conducted to see the effect of the size of pileus on its biochemical composition in the milky mushroom variety Calocybe indica. The fresh milky mushroom sporocarps of different sizes were selected for the studies which were oven dried at 40 0C ground into fine powder and estimated for their biochemical composition. The results revealed that the protein content increased with increase in size of pileus up to 4.3cm diameter and then declined with increase in size of pileus. Lipid analysis in mushroom showed that the per cent lipid content decreased with increase in size of the pileus. While there is no specific correlation between the quantity of carbhohydrates and size of the pileus, but there is a clear cut decrease in phenol quantity with increase in pileus size.
