摘要:
选定福建茶叶分选碎屑为原料进行了提取水溶性物质的实验,研究了提取工艺中料水比、浸提时间对水提物提取率的影响.经过蒸发浓缩和冷冻干燥处理得到了浅色的干粉.以福建茶叶分选碎屑的干品为基准,水提物提取率达47.6%.以葡萄糖为标准、蒽酮硫酸法于620 nm处比色,测得干粉中多糖含量5.05%,考马斯亮蓝法测得蛋白质含量5.58%,105 ℃恒重法测得水分6.61%,550 ℃高温灰化法测得灼烧残留物14.75%,重量法测得果胶含量18.09%.
Abstract:
The effect of time and ratio of tea to water(W/V)on the yield of tea polysaccharides from Fu jian tea tailings were researched in this paper. The powder of aqueous extract were obtained through evaporate concentration and refrigerate desiccation. The extraction rate was 47.6% based on the dry powder. The absorbance was measured by anthronesulfuric colorimetry at 620 nm while glucose was used as the standard. The content of polysaccharides in the dry powder was 5.05% by this method as well as 5.58% of protein by Coomassie brilliant blue method, 6.61% of water by constant weight method of 105 ℃, 14.75% of ash by high temperature carbonization of 550 ℃, 18.09% of pectin by gravimetric method, respectively.
