响应面法优化微波辅助提取姜黄中姜黄素工艺的研究

Optimization of microwave-assisted extraction of curcumin from turmeric by response surface methodology

摘要: 采用微波辅助提取技术提取姜黄中的姜黄素,以姜黄素提取率为指标,通过响应面优化实验,考察了料液比、处理时间、微波功率、乙醇浓度等因素对提取率的影响。结果表明,微波提取的最佳工艺参数是:料液比为1:43、微波功率为540W,处理时间为30s,溶剂为73%乙醇溶液,在此参数下,姜黄素提取率为0.2045%。

Abstract: The optimization of extraction technology of curcumin from turmeric with microwave-assisted method was examined by curcumin yield, using ethanol as extracting solvent based on response surface methodology.Results showed that the optimum microwave extraction parameters were:solid-liquid ratio of 1:43, microwave power for 540W, microwave treatment time for 30s and solvent 73% ethanol solution.Under these conditions, curcumin yield was 0.2045%.
