Nutritional values and antioxidant potential of some edible mushrooms of Kashmir valley.

Metadata-grounded summary

Citation abstract

Mushrooms are considered rich in proteins, carbohydrates and other nutrients. The present study was carried out to evaluate some edible mushrooms of Kashmir valley for their protein, carbohydrate and lipid contents. The highest protein content was found in Boletus edulis (2.20g) followed by Agaricus bisporus (1.80g), Pleurotus ostreatus (1.68g), Morchella esculenta (1.62g) and Pleurotus sajor caju (1.6g). Carbohydrate content also showed variation in all the five tested edible mushroom species, the highest carbohydrate content observed in Boletus edulis (6.0g) followed by Agaricus bisporus (4.85g), Pleurotus ostreatus (4.30g), Morchella esculenta (4.25g) and Pleurotus sajor caju (3.35g) respectively. Similar results were observed for lipid content. The present study was also investigated for the antioxidant potential of aqueous extract of mushroom species by the methods of DPPH radical scavenging activity, hydroxyl radical scavenging activity and superoxide radical scavenging activity. All these in vitro antioxidant activities were concentration dependent, which were compared with standard antioxidant Catechin.
