作物节木代料香菇与纯木屑代料香菇蛋白质营养比较研究

COMPARATIVE RESEARCH ON PROTEIN NUTRITIONAL VALUE IN FRUIT-BODIES OF LENTINULA EDODES CULTIVATED WITH SAWDUST-SAVING SUBSTITUTES

采用国际通用的蛋白质营养评价方法,对2种作物节木代料和纯木屑代料(CK)香菇子实体蛋白质的营养价值进行了比较研究。结果表明,2种作物节木代料香菇子实体蛋白质的NI指标低于纯木屑代料香菇,而CS、AAS、EAAI、BV、SRCAA等指标均高于纯木屑代料香菇。结论:作物节木代料香菇子实体和纯木屑代料香菇子实体蛋白质均具有较高营养价值,且二者之间无显著差异。

The protein nutritional value of L. edodes fruit-bodies cultivated with two kinds of crop sawdust-saving substitutes and sawdust were studied with the international protein assessment method .The results showed that： NI （nutritional index） in Lentinula. edodes fruit-bodies cultivated with two kinds crop sawdust-saving substitutes lower than that of sawdust cultivation, whereas CS （chemical score）, AAS （amino acid score）, EAAI （essential amino acid index）, BV （biological value）, SRCAA （score of ratio coefficient of amino acid） were higher, the result suggested that the nutritional value of L edodes fruit-bodies cultivated either by crop sawdust -saving substitutes or sawdust was higher and had no significant difference between them.
