摘要
原木灵芝孢子粉堆积密度为0.22～0.25g/cm^3,每克含有0.97～1.15 × 10~10个孢子,其水分含量为8.39％～8.92％。分析结果表明,孢子粉含粗蛋白14.26％～17.80％,粗脂肪3.57％～4.35％,总糖8.37％～9.32％,水溶性多糖1.43％～1.90％,粗纤维2.36％～3.52％,灰分3.44％～4.01％孢子粉中Pb、Cd、Hg、As等重金属含量合乎卫生指标。提取结果表明,孢壁主要成分几丁质含量为52.08％～57.64％,并采用红外光谱分析比较了孢子与蟹壳几丁质成分。
The stacked density of log-cultivated Ganoderma lucidum spores is 0.22-0.25g/cm9 with 0.97-1.15×1010 spores per gram, and its moisture content is about 8.39%-8.92%. The analytic results showed that the content of crude protein, crude fat, total carbohydrate, soluble polysaccharide, crude fiber and ash was 14.26% - 17.80%, 3.57%-4.35%, 8.37%-9.32%, 1.43%-1.90%, 2.36%-3.52% and 3.44%-4.01% resp., that the content of heavy metal Pb, Cd and Hg was coincided with the hygienic standard, and that the content of chitin, main component of spore-wall, was about 52.08% - 57.88%. while the component of chitin obtained from G. lucidum spores and crab-shell was analysed and compared by infra-red spectrum in this study
