Analysis and Comparison on the Nutrients in Pleurotus nebrodensis and Pleurotus eryngii

[Objective] The study aimed to compare the nutritional components contents in the fruiting body of Pleurotus nebrodensis and Pleurotus eryngii.[Method] With the fresh P.nebrodensis and P.eryngii purchased from the market as the tested material,the amino acid and conventional nutritional components contents in dry fruiting body of P.nebrodensis and P.eryngii were determined by micro-Kjeldahl method and Hitachi model 835-50 amino acid analyzer.[Result] The total amino acid content of P.nebrodensis was 167.2 g/kg,in which,the essential amino acid,sweet taste amino acid and delicious amino acid accounted for 40.47%,20.81% and 19.20% of totle amino acid resp.Total amino acid content of P.eryngii was 140.8 g/kg in which,the essential amino acid,sweet taste amino acid and delicious amino acid accounted for 40.06%,19.39% and 24.64% of total amino acid resp.The contents of protein,crude fiber and polysaccharide in the fruiting body of P.nebrodensis were 2.91%,4.11% and 1.28% higher than that in the fruiting body of P.eryngii resp.The ash content in P.eryngii fruiting body was 0.92% higher than that in P.nebrodensis.[Conclusion] According to the requirement of high protein content for food,the nutritional value of P.nebrodensis was higher than P.eryngii.According to the requirement of flavor for food,P.eryngii is better than P.nebrodensis.
