Study on Extraction of Xylan from Bamboo Shoot Shell

摘要

Using bamboo shoot shell as raw material, the experiment utilized the method of alkali extraction after bamboo shoot shell was pretreated. Effects of alkali concentration,extraction temperature, ratio of solid to liquid, and extraction time on yield of xylan were analyzed. The conditions of alkali extraction were: alkali concentration 5 %, ratio of solid to liquid 1:10 (g:mL),extraction time 3 h, extraction temperature 120 °C. The yield of xylan from bamboo shoot shell reached 24.77 %,which shows that:bamboo shoot shell is a good raw material with the content of 35.08 % hemicellulose in it.
