摘要
塔拉多糖是一种半乳甘露聚糖胶,对于我们具有非常重要的应用价值。本实验主要对塔拉提取物中的塔拉多糖进行脱色工艺化研究;在单因素实验的基础上,对活性炭颗粒质量、脱色时间、脱色温度以及脱色次数这四种因素进行正交优化实验,其最佳脱色实验参数为:活性炭颗粒0.6 g,脱色45 min,脱色温度45℃脱色次数3次,脱色率可以达到50.21%,同时多糖类保留率为90.39%。
Tara polysaccharide is a kind of galactose,which has a very important application value for us.We mainly studies the tara polysaccharide extract from tara seeds.By the single factor experiment,we optimized four factors including the activated carbon particle quality,decolorization time,decolorization temperature and decolorization times.The best optimum conditions were under activated carbon particles of 0.6 g,decolorization time of 45 min,decolorization temperature of 45℃,decolorization times of 3,the decolorization rate can be achieved 50.21%,at the same time,and the retention rate of polysaccharide was 90.39%.
