阿魏菇与白灵菇蛋白质的营养评价

The Nutritional Assessment of the Proteins from the Fruiting Bodies of Pleurotus ferulae Lanzi and P.eryngii var.nebrodensis

采用国际上通用的营养价值评价方法,比较全面地评价了阿魏菇和白灵菇子实体的营养价值。阿魏菇和白灵菇子实体蛋白质的氨基酸评分(AAS)、化学评分(CS)、必需氨基酸指数(EAAI)、生物价(BV)、营养指数(NI)、和氨基酸比值系数分(SRCAA)分别为51．4、52．1、71．9、66．7、11．30、74．40和60．0、42．9、70．4、65．0、10．35、68．39,阿魏菇6项指标中有5项高于白灵菇,这说明阿魏菇是较好的蛋白源。

The nutritional value of the fruiting bodies of Pleurotus ferulae and P. nebrodensis were assessed using the method adopted internationally. The amino acid score （ AAS）, chemical score （CS） , essential amino acid index （ EAAI ）, biological value（ BV ）, nutritional index（ NI） and score of ratio coefficient of amino acid （ SRCAA ） of the proteins from fruiting bodies of P. ferulae and P. nebrodensis were 51.4,52.1,71.9,66.7,11.30,74.40 and 60.0,42.9,70.4,65.0,10.35 and 68.39 ,respectively. Five of the six indexes of P. ferulae were higher than those of P. nebrodertsis. The results showed that the protein nutrient value of P. fertdae was much higher. P. ferulae could be, therefore, considered as a good source of the proteins.
