摘要
以柑桔皮粉为原料,对乙醇-纤维素酶溶液提取柑桔皮总黄酮工艺进行系统地研究。通过单因素试验,确定影响提取率的主要工艺参数,即浸提时间、浸提温度、pH值和酶用量,并在此基础上采取L9(34)正交优化试验。结果表明:最佳的工艺条件为酶用量0.5%、时间130 min、pH4、温度50℃。在此条件下,所得总黄酮含量为3.46%。
It used the citrus peel powder to investigate the total flavonoids with ethanol-cellulose treatment solution. The main influence factors （extraction time, extraction temperature, pH value and the ratio of celMase to material） were ascertained by single factor experiments. And the orthogonal test design Lg（34）was used to optimize the conditions of cellulose-assisted extraction. Based on the mathematical analysis, the optimum conditions were obtained as follows： the additived ratio of cellulose was 0.5%, the time was 130 min, pH value was 4 and the temperature was 50 ℃. Under the best extraction conditions, the total content of flavonoids was 3.46%.
