Optimizing Conditions for Microwave-assisted Extraction of Cochineal Dye Using Response Surface Method
摘要
Abstract
Cochineal (Dactylopius coccus Costa) dye was extracted by microwave-assisted extraction with water. Effects of single-factor test on the yield of cochineal dye was carried out. The results show that for 5 g cochineal, the suitable conditions for extraction of dye are cochineal sample soaked in water for 40min before microwave treatment, ratio of liquid to material 7:1 (g: mL) , microwave power 700 W, microwave treatment time 60 s, and extract with water-bath at 75℃ for 40 min after microwave treatment. According to the single-factor test, the microwave-assisted extraction process parameters for extraction of cochineal dye were optimized using response surface method. The results show that the optimum parameters should be as follows; cochineal 5 g, ratio of liquid to material 7.5, microwave power 714 W, microwave treatment time 73 s. The extraction yield of conchineal dye is up to 7.30%. Under this conditon the reasonable extracting times is 12, the total yield of conchineal dye is 29.95 % and extraction yield is 95.13 %.关键词
