以桑枝屑和杂木屑为试材,采用标准及实验室常用方法对香菇营养成分进行测定,研究桑枝屑和杂木屑2种培养料对香菇产量和营养成分(蛋白质、氨基酸、脂肪、多糖、纤维、部分矿质元素)含量的影响。结果表明:桑枝屑栽培的单袋香菇产量比杂木屑的低6.4%,但生物转化率比木屑的高1.7%,粗蛋白质含量是杂木屑栽培的1.03倍,但总氨基酸含量和必需氨基酸含量都比杂木屑香菇中的略低一些;脂肪含量是杂木屑栽培的1.82倍,纤维含量是杂木屑栽培的1.01倍,多糖含量是杂木屑栽培的1.34倍;重金属铅含量仅为杂木屑的11.3%,均达到国家绿色食品标准;矿质元素除钾元素外,钙、镁、铁、锌均高于杂木屑栽培的香菇。可见,用桑枝屑栽培的香菇子实体的营养性和药用保健性优于杂木屑栽培的香菇。
Using mulberry leaf chips and miscellaneous sawdust as test materials, the nutritional components of Mushrooms were determined by standard and laboratory methods. The effects of mulberry chips and miscellaneous sawdust on the yield and nutrition of mushrooms (protein, amino acids, fat, polysaccharides , Fiber, some mineral elements) content. The results showed that the yield of single-bag mushrooms with mulberry branchlets was 6.4% lower than that of the wood chips, but the bioconversion rate was 1.7% higher than that of the wood chips and 1.03 times of the crude protein. The total amino acid content and essential amino acid content Is slightly lower than the miscellaneous sawdust mushrooms; fat content is 1.82 times the cultivation of sawdust, fiber content is 1.01 times the cultivation of sawdust, polysaccharide content is 1.34 times the sawdust cultivation; heavy metal lead content of only sawdust 11.3 %, All reached the national green food standards; mineral elements in addition to potassium, calcium, magnesium, iron, zinc were higher than the mushrooms cultivated by sawdust. It can be seen that the nutrition and medicinal health care of the fruiting bodies of mushrooms cultivated with Morus alba are superior to the mushrooms cultivated with the sawdust.
