摘要
为探究富硒香菇营养成分和挥发性风味物质与普通香菇的差异,以湖北随县施硒肥栽培的富硒香菇和未施硒肥的普通香菇为研究对象,对2种香菇的帽和柄的营养成分(总硒、水分、蛋白质、粗纤维、灰分、粗多糖、脂肪和氨基酸)和挥发性风味物质进行了分析。结果表明,富硒香菇的帽和柄总硒含量分别为1.34 mg/kg和1.13 mg/kg,富硒香菇帽和柄的蛋白质、粗纤维、总灰分、粗多糖、脂肪和总氨基酸含量均高于普通香菇。气相离子迁移色谱(GC-IMS)结果表明,富硒香菇较普通香菇含有更多的挥发性风味物质,可为富硒香菇进一步作为功能性食品开发和应用提供理论依据。
In order to study the differences in nutritional components and volatile flavor compounds between selenium-rich Lentinus edodes and common Lentinus edodes,the selenium-rich Lentinus edodes cultivated and the common Lentinus edodes without selenium fertilizer in Sui county,Hubei province,were used as the research objects,the nutritional components(total selenium,water,protein,crude fiber,ash,crude polysaccharide,fat and amino acid)and volatile flavor compounds in the cap and stalk of two Lentinus edodes were analyzed.The results showed that the total selenium content in cap and stalk of selenium-rich Lentinus edodes was 1.34,1.13 mg/kg,respectively.The contents of protein,crude fiber,total ash,crude polysaccharide,fat and total amino acid in the cap and stalk of selenium-rich Lentinus edodes were higher than those in the cap and stalk of common lentinus edodes.The results of GC-IMS showed that the selenium-rich Lentinus edodes contained more volatile flavor substances than the common Lentinus edodes,which could provide a theoretical basis for the further application and development of the selenium-rich Lentinus edodes as a functional food.
