微波辅助提取茶籽多糖工艺条件的研究

Study on the Conditions of Extracting Polysaccharides in Tea seed by Means of Microwave Assistant Extraction

利用微波结合正交试验的方法研究了微波对茶籽多糖提取条件的影响。结果表明:在试验条件限定的范围内,对浸出率影响的主次顺序为功率＞pH＞固液比＞时间。根据各因素不同水平均值多重比较(SSR)和多糖活性可知,方案:浸提功率400W、固液比1:30、pH为5、浸提时间30s最合适。而微波辅助提取对茶籽多糖清除·OH的能力影响不显著,而对茶籽多糖清除O_2-的能力有较好的增强作用。

By means of microwave assistant extraction orthogonaUy design, influence of microwave on extraction conditions of tea seed Polysaccharides were conducted by using tea seed Polysaccharides. Results showed that the extraction rate of tea seed Polysaeeharides was affected obviously in successive order of power, pH, ratio between tea and water and time in experiment range. Synthetically plan included power of extraction was 400W, ratio of solid to liquid was 1：30, pH was 5 and time of extraction was 30s by multi-comparison of experimental factors. Microwave assistant had no disadvantageous effects on tea seed Polysaccharides＂ cleaning effects of ＂OH and had advantageous effects on tea seed Polysaceharides＂ cleaning effects of 02.^-
