贵州不同地区红托竹荪不同部位的营养成分分析

Analysis of Nutritional Components in Different Parts of Dictyophora rubrovalvata from Different Areas of Guizhou

以贵州织金县和纳雍县的红托竹荪为研究对象,对其菌盖、菌柄、菌托中的各种营养成分进行比较分析。试验结果表明,2个地区的红托竹荪均含有糖、蛋白质、脂肪、纤维素、氨基酸和矿物质6种营养成分,具有较高的营养价值。红托竹荪各部位之间6种营养成分的含量差异显著(P<0.05),2个地区的红托竹荪相同部位中同种成分的含量也存在显著差异(P<0.05)。综合2个地区红托竹荪的检测结果发现,糖类是红托竹荪各部位中含量最高的成分,含量为26.91 g·100^(-1)g^(-1)~60.61 g·100^(-1)g^(-1);其次是蛋白质,含量为13.42 g·100^(-1)g^(-1)~27.08 g·100^(-1)g^(-1)。红托竹荪的菌托中均含有6种检测的营养成分,且菌托中的各营养成分含量与菌盖和菌柄中的含量差异不显著,因此红托竹荪菌托亦具有较高的利用价值。

Taking Dictyophora rubrovalvata from Zhijin county and Nayong county in Guizhou Province as the research objects,the nutritional components in the cap,stalk and volva of D.rubrovalvata were compared and analyzed.The experiment results showed that the D.rubrovalvata from two regions both contain six nutritional components,including sugar,protein,fat,cellulose,amino acids and minerals,and they both have high nutritional value.There are significant differences in the content of six nutritional components between the different parts of D.rubrovalvata(P<0.05),and the content of the same component in the same part of D.rubrovalvata from the two regions was also significantly different(P<0.05).The test results of D.rubrovalvata from the two regions showed that sugar was the highest content component in each part of D.rubrovalvata,with a content of 26.91 g·100^(-1)g^(-1)-60.61 g·100^(-1)g^(-1).The second was protein,which ranged from 13.42 g·100^(-1)g^(-1)-27.08 g·100^(-1)g^(-1).All the tested nutritional components were detected in the volva of D.rubrovalvata,and the content of each nutritional component in the volva was not significantly different from the content in the fruit body.Therefore,the volva of D.rubrovalvata also has a high utilization value.
