摘要
本文以纤维素得率和残余蛋白质含量为评价指标,研究氢氧化钠溶液质量分数、提取温度、提取时间3个因素对海带渣纤维素提取的影响.结果显示,在NaOH溶液质量分数为3.0%,提取温度为100℃,提取时间为 140 min的条件下,海带渣纤维素的得率为33.46%,残余蛋白质含量为0.98%,且红外分析显示提取物具有纤维素的特征峰.
Abstract
Using cellulose yield and residual protein content as evaluation indicators,the effects of NaOH concentration,temperature,and extraction duration on cellulose extraction were studied.The yield of cellulose from kelp residue is 33.46%,and the residual protein content is 0.98%when treated with a 3.0%NaOH solution at 100℃for 140 minutes.Additionally,FTIR analysis revealed that characteristic peaks attributed to cellulose were present in the extract.
