【中文摘要】 采用國際上通用的營養(yǎng)價值評價方法,對不同碳氮比培養(yǎng)料栽培的豬肚菇第二潮子實體進行蛋白質(zhì)營養(yǎng)價值評價。結(jié)果表明,子實體蛋白質(zhì)中,必需氨基酸含量以培養(yǎng)料Ⅲ(碳氮比為35:1)的最高,之后依次為培養(yǎng)料Ⅳ、Ⅱ、Ⅰ、Ⅴ、Ⅶ和Ⅵ;而蛋白質(zhì)營養(yǎng)綜合評價結(jié)果則以培養(yǎng)料Ⅰ(碳氮比為25:1)的最高,其次為培養(yǎng)料Ⅲ,再次為培養(yǎng)料Ⅱ、Ⅴ、Ⅶ、Ⅵ和Ⅳ。

【英文摘要】 Protein from Panus giganteus fruit bodies cultivated using substrates with different C:N ratios was assessed in terms of essential amino acid content and six nutritional quality indices--Amino Acid Score (AAS),Chemical Score (CS),Essential Amino Acid Index (EAAI),Biological Value (BV),Nutritional Index (NI) and Amino Acid Ratio Coefficient Score (A.ARCS).The highest content of essential amino acids was recorded in protein from fruit bodies cultivated using substrateⅢwith a C:N ratio of 35:1.Protein from fruit bodies cultivated using substrateⅠ(C:N ratio 25:1) had a superior nutritional value,and was ranked highest in terms of three protein quality indices (CS,AARCS and NI),second highest in the case of EAAI and BV,and had the third highest AAS.Protein from fruit bodies cultivated using substrateⅢ(C:N ratio 35:1) was ranked highest in terms of two indices (EAAI and BV) and second,third,fourth and seventh in the case of AAS,NI,CS and AARCS,respectively.
