Optimization of Ultra High Pressure-assisted Extraction of Tea-polyphenols by Response Surface Methedology
摘要
Abstract
To obtain the optimum ultra high pressure-assisted extraction technology of tea-polyphenols from low value tea.On the basis of single-factor test,the mathematical regression model is established about the dependent variable(extraction yield of tea-polyphenols) and independent variables (alcohol concentration,time of maintain pressure and extraction pressure) through Box-Benhnken center composite design and response surface methodology.The results indicated that the optimal extraction conditions were alcohol concentration of 60％,processing time of 1.5 rain,extraction pressure of 300 MPa.Under these conditions,the predictive maximum yield of tea-polyphenols from low value tea was 31.07％,the validation value was 30.87％.The relative error between them was 2.59％.The standardized regression equation was Y1=776.3561-1.3356X1+ 123.093X2+163.7406X3-274.2023X1X1-145.2251X2X2.关键词
