【摘要】 測(cè)定了真姬菇菇腳和菌糠中蛋白質(zhì)和氨基酸的含量,應(yīng)用模糊識(shí)別法和氨基酸比值系數(shù)法,以雞蛋蛋白為標(biāo)準(zhǔn)蛋白,以WHO/FAO的必須氨基酸參考模式為評(píng)價(jià)標(biāo)準(zhǔn),對(duì)真姬菇菇腳和菌糠的蛋白質(zhì)營(yíng)養(yǎng)價(jià)值進(jìn)行了全面評(píng)價(jià),并與真姬菇子實(shí)體的蛋白質(zhì)進(jìn)行比較。結(jié)果表明:真姬菇菇腳和菌糠蛋白質(zhì)中總氨基酸含量為71.50%和65.92%,氨基酸種類(lèi)齊全,必需氨基酸占總氨基酸量的40.16%和38.65%,相對(duì)于雞蛋蛋白(標(biāo)準(zhǔn)蛋白)的貼近度為0.8360和0.7520,第一限制性氨基酸均為蛋氨酸+胱氨酸,氨基酸比值系數(shù)分為76.77和70.13,雖然菇腳和菌糠的蛋白質(zhì)含量比均子實(shí)體低,但與子實(shí)體一樣具有較高的蛋白質(zhì)營(yíng)養(yǎng)價(jià)值。
【Abstract】 The contents of protein and amino acids of Hypsizygus marmoreus stembase and mushroom barn were determined,using fuzzy identification mode and ratio coefficient mode of amino acid.Using egg protein as standard protein,the nutritive value of protein of Hypsizygus marmoreus stembase and mushroom barn by the evaluation standard of must amino acid reference mode of WHO/FAO and comparison to the protein of fruitbodies of Hypsizygus marmoreus were evaluated.The results showed that the total amino acid...
