19个平菇品种子实体蛋白质和多糖含量研究
Study on Contents of Protein and Polysaccharide in 19 Pleurotus ostreatus Strains
摘要
Abstract
[ Objective ] The research aimed to compare the difference of the nutritional value of 19 Pleurotus ostreatus strains. [ Method ] The tested 19 strains of P. ostreatus were first cultured for their fruiting bodies, and then the first batch of fruit bodies were collected and the contents of protein and polysaccharide in fruiting bodies were determined by bicinchoninic acid ( BCA ) method and phenol-sulphuric acid method after pretreating the samples. [ Result] Among 19 strains, the protein content of Heifeng 268 was the highest, accounting to 5.99％ of fresh weight of the fruiting body and that of Xinyu 2000 and Pinggu 9906 were the next, accounting to 5. 453％ and 4.594％ of fresh weight of the fruiting body resp. , and 3 strains had significant differences when compared with other strains and they were the advantage strains in the selection for the protein content; the polysaccharide contents of Ping 82 and Ping 12 were the highest, accounting to 2.806％ and 2.274％ of dry weight of fruiting body resp. , and the 2 strains all had significant differences when compared with other strains and they were the advantage strains in the selection for the polysaccharide content. [ Conclusion ] The contents of protein and polysaccharide in different strains of P. ostreatus were significantly different. They should be developed in food processing area due to its different value.关键词
