竹笋壳化学成分分析

Analysis of Chemical Constituents of Bamboo Shell

按照GB5888—86《苎麻化学成分定量分析方法》,对所选湖北咸宁的竹笋壳原料进行化学成分定量分析。分别确定了竹笋壳的脂腊质含量为1.33%,水溶物含量为7.73%,果胶含量为0.82%,半纤维素含量为28.12%,木质素含量为20.34%,纤维素含量为41.66%,与苎麻﹑亚麻﹑竹原纤维相比,竹笋壳中的纤维素含量偏低,而半纤维素和木质素含量则偏高。

According to GB5888-86 ＂Quantitative Analysis Methods of Chemical Constituents of Ramie＂,the quantitative analysis of chemical constituents of bamboo shell from Xianning County of Hubei Province indicates that the content of waxy fat is 1.33%,water soluble is 7.73%,pectin is 0.82%,hemicellulose is 28.12%,lignin is 20.34% and cellulose is 41.66%.Compared with ramie,flax and bamboo fiber,the content of cellulose in bamboo shell is on the low side while the content of hemicellulose and lignin in bamboo shell is on the high side.
