Nutritional and antinutritional content of Macrocybe gigantea (Massee) Pegler & Lodge, another edible mushroom of commercial importance

The objective of this work was to assess nutritional and antinutritional content of Macrocybe gigantea cultivated on different locally available agrowastes. Assessment of nutritional content showed maximum moisture content (85.6%) and ash content (8.6 g 100g ) in the sporophores cultivated on pearl millet stalk -1 , whereas maximum fat content (2.3 g 100g ) and protein content (22.6 g 100g ) were detected from the -1 -1 sporophores cultivated on wheat straw. Highest crude fiber content (19.5 g 100g ) was recorded from the -1 sporophores cultivated on maize stalk. A total of nineteen amino acids were detected from the sporophores, which included nine essential and ten non-essential aminoacids. In addition, some of the essential minerals like potassium, sodium, copper, calcium, magnesium and zinc were also recorded from the sporophores of M. gigantea, indication the presence of essential nutrients and can be included in the diet of people belonging to the developing and under developed countries. Two antinutritional components i.e. tannins and phytic acid were detected which ranged from 0.13 mg g to 0.21 mg g and 0.06 mg g to 0.10 mg g -1 -1 -1 -1 respectively. These findings revealed that the cultivated sporophores of M. gigantea can be utilized as an accessible source of nutrients with very low antinutritional components..
