秦巴地区栽培赤芝营养成分的分析

目的]较为系统地分析秦巴地区人工栽培赤芝子实体的营养成分。方法]以采自陕西省略阳县人工栽培赤芝基地的赤芝子实体为试材,测定了秦巴地区栽培赤芝子实体中的5种营养成分。结果]在测定的18种氨基酸中,人工栽培赤芝子实体的8种必需氨基酸含量占氨基酸总量的42%;达到FAO/WHO提出的40%的要求;矿质元素Ca、Cu、Zn、Na、Fe、Mg和Mn含量分别为151.92、6.69、26.27、89.53、19.80、494.69和7.66 mg/100g,其中Zn、Mg、Mn、Cu含量均高于薄盖灵芝菌粉;多糖、粗蛋白和粗脂肪含量分别为19.65%、15.38%和6.81%,均高于野生灵芝,粗纤维含量为45.43%,远高于液体培养的泰山赤灵芝;菌盖中各营养成分含量均高于菌柄。结论]该研究为秦巴地区人工栽培赤芝的开发利用提供指导意义。

Analysis of Nutrition Components in Fruiting Bodies of Cultivated Ganoderma lucidum in Qinba District

Objective] The aim of the study was to analyze the nutrition components in fruiting bodies of cultivated Ganoderma lucidum in Qinba district.Method] The fruiting bodies of G.lucidum selected from the base of artificially cultivating G.lucidum in Luoyang county in Shaanxi province were taken as the tested materials to determine 5 kinds of nutrition components in fruiting bodies of cultivated G.lucidum in Qinba district.Result] Among 18 kinds of determined amino acids,the 8 kinds of essential amino acid contents in the fruiting bodies of artificially cultivating G.lucidum was 42% of total amino acid contents,which reached the requirement of 40% put forward by FAO/WHO.The contents of mineral elements such as Ca,Cu,Zn,Na,Fe,Mg and Mn were 151.92,6.69,26.27,89.53,19.80,494.69 and 7.66 mg/100g resp.,in which,the contents of Zn,Mg,Mn and Cu were higher than that in mycelia powder of G.capuse.The contents of polysaccharide,crude protein and crude fat were 19.65%,15.38% and 6.81% resp.,being higher than that in wild Ganoderma spp.and the crude fiber content was 45.43%,being higher than that in Tanshan G.lucidum.The various nutrition components in pileus was higher than that in stipe.Conclusion] This study prodide the guidance meaning for the development and utilization of artificially cultivating G.lucidum in Qinba district.
