Abstract:
To establish a new method for the extraction of turmeric oil and curcumin by supercritical CO2 and microwave combined technique,turmeric powder was pre-treated with supercritical CO2 to obtain turmeric oleoresin,and then microwave was used to extract curcumin.Orthogonal experiment was applied to optimize the process parameters of the microwave assisted extraction,and the parameters about extraction condition,production yield,purity of different extraction technologies were compared.The optimum conditions of curcumin extracting were:temperature 45 ℃,ratio of material to liquor 1∶11,80% ethanol as extracting solvent,time 2 min,yield of 3.22%.
Key words: turmeric, curcumin, microwave assisted extraction, supercritical CO2 extraction
