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 bulk density of log fungus spore powder is 0.22 ~ 0.25g / cm ~ 3, containing 0.97 ~ 1.15 × 10 ~ 10 spores per gram, and its moisture content is 8.39% ~ 8.92%. The results showed that spore powder contained 14.26% ~ 17.80% of crude protein, 3.57% ~ 4.35% of crude fat, 8.37% ~ 9.32% of total sugar, 1.43% ~ 1.90% of water-soluble polysaccharide, 2.36% ~ 3.52% of crude fiber, % ~ 4.01% Spore powder Pb, Cd, Hg, As and other heavy metals content in line with health indicators. The results showed that the main components of the spore wall chitin content of 52.08% ~ 57.64%, and the infrared spectrum analysis of spores and crab shell chitin composition.
