油茶饼粕中茶皂素醇提工艺条件优化
Optimization of alcohol extraction for tea saponin from oil-tea cake by response surface methodology
摘要
Abstract
Using oil-tea cake as raw material,the extraction processing of tea saponin by ethanol extraction method was studied in this paper.Based on single factor experiments,the effect of the extraction factors,such as liquid-solid ratio,extraction temperature and time on the tea saponin yield were analyzed emphatically by response surface methodology.The results showed that the optimum conditions by 70％ ethanol as solvent were as follows:concentration of ethanol was 70％,solid-liquid ratio was 1 ∶ 7(m ∶ V),extraction time was 110 min,extraction temperature was 60 ℃,and the tea saponin yield was 8.34％ under these conditions.关键词
