蝉花菌质主要营养成分和活性成分分析

蝉花是寄生在蝉幼虫上的一种虫草菌,蝉花菌质是指由蝉花的营养菌丝和经发酵的培养基质组成的营养物质。通过对蝉花菌质营养成分和活性成分的研究和分析,结果表明:蝉花菌质蛋白含量为16.17%、总糖含量为38.87%、脂肪酸含量为1.43%,其中不饱和脂肪酸含量达1.18%。通过对蝉花菌质氨基酸的分析,在FAO/WHO的评分模式中,其第一限制氨基酸是赖氨酸。蝉花菌质VE和VC的含量分别达1 833mg/kg和239mg/kg。此外,蝉花菌质中还有腺苷、甘露醇等虫草类真菌的活性成分。该研究结果为蝉花菌质的进一步开放利用奠定了理论基础。

Analysis of nutritional and bioactive components of solid-state fermented substrate of Isaria cicadae

In the present work, the nutritional and bioactive components of the solid-state fermented substrate of I. cicadae were studied. And the results indicated that the contents of protein, total sugar and fat acid were 16.17%, 38.87% and 1.43%, respectively. The unsaturated fat acid content was 1.18%. The amino acid profile was analyzed and lysine was the first restrictive amino acid in the FAO/WHO model. The contents of vitamin E and C were 1 833 mg/kg and 239 mg/kg, respectively. Furthermore, the fermented substrate contained adenosine, mannitol and polysaccharide. This work provided basic information for the further development of Fermented Substrate of I. cicadae.
