摘　　要：测定了四种碳源对虎奶菇菌核蛋白质营养价值的影响。结果表明 ,以玉米淀粉为碳源 ,虎奶菇菌核蛋白质的化学评分、必需氨基酸指数、生物价和营养指数分别为 11.6 3、6 9.80、6 4.4 0和 9.98,均居四种参试碳源的第一位 ;氨基酸评分和氨基酸比值系数分分别为 14 .5 5和12 .4 5 ,均居四种参试碳源的第二位。这些结果证实 ,以玉米淀粉为碳源 ,虎奶菇菌核蛋白质营养价值高 。Effects of 4 kinds of carbon sources on the nutrient value of protein in Pleurotus tuber regium sclerotium were investigated. The results showed that the chemical score (CS), essential amino acid index (EAAI), biological valence (BV) and nutritional index (NI) in the protein of P.tuber-regium sclerotium cultivated with corn starch as its carbon source were 11.63, 69.80, 64.40 and 9.98 resp, all held the first place in 4 carbon sources tested; and that its amino acid score (AAS) and score of ratio coefficient of amino acid (SRCAA) were 14.55 and 12.45 resp, all held the second place in 4 carbon sources tested. So it was confirmed in our experiment that P.tuber regium sclerotium cultivated with corn starch as its carbon source bore protein with high nutrient value, and corn starch should be extended as the carbon source of artificially cultivated P.tuber-regium.
