- 摘要:
- 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。
- Abstract:
- Taking mulberry sawdust and wood sawdust as test materials,using the national standard and commonly laboratory methods for the determination of nutritional components in Lentinus edodes，the effect of mulberry sawdust and wood sawdust on mushroom yield and nutrient composition (content of protein，amino acid，fat，carbohydrate，fiber，mineral element) were studied. The results showed that，the yield of per bag cultivated with mulberry sawdust was 6.4% lower than that of cultivated with wood sawdust,but the biological efficiency was higher 1.7%.The content of crude protein of cultivated with mulberry sawdust was 1.03 times than that of cultivated with wood sawdust,the total amino acid content and essential amino acid content of cultivated with wood sawdust were higher than that of cultivated with mulberry sawdust.The content of fat,fibre,polysaccharides of cultivated with mulberry sawdust were 1.82,1.01,1.34 times than that of cultivated with wood sawdust.The content of heavy metal plumbum was only 11.3% of the cultivated with wood sawdust,and all met the national green food standards.The contents of mineral elements were higher than cultivated with wood sawdust except the content of potassium.Altogether,the nutrient composition of Lentinula edodes cultivated with mulberry sawdust was not inferior to that cultivated with wood sawdust.
