高温高压条件制备石榴皮鞣花酸的试验研究
Study on preparation of ellagic acid from pomegranate peel by high temperature and high pressure
摘要
Abstract
Objective:To explore a new method of preparation of pomegranate ellagic acid.Methods:The effect of hydrolysis temperature(pressure),hydrolysis time and sulfuric acid concentration (v/v)on ellagic acid yield were studied respectively with high pressure steam sterilizer as the reactor,and also the process parameters were optimized.Results:The highest ellagic acid yield was 3.09 ％ under the optimum conditions of hydrolysis temperature (pressure) of 115 ℃ (169 kPa),hydrolysis time of 2 h,sulfuric acid concentration of 5％ (v/v),and was increased by 25.10％ compared with the atmospheric pressure.Conclusion:Under the condition of high temperature and high pressure,granatanine extracten by hydrolysis method of preparation of ellagic acid efficiency was higher.It provided technical basis for the improvement of production process.关键词
