Title: Comparison and Optimization of Extraction Process of Canthaxanthin Produced by Gordonia sp.
Abstract: The extraction method of canthaxanthin produced by Gordonia sp was researched.The pigment was extracted with five different kinds of methods such as dimethyl sulfoxide(DMSO) extraction,combing hydrochloric acid(HCl) with heating method,snail enzyme treatment and freeze-thaw method.Furthermore,L9(34) orthogonal test was used to optimize the technology with extraction temperature,extraction time,ratio of material to solvent as influence factors.The results showed that DMSO method was suitable for extraction of canthaxanthin and the canthaxanthin concentration could reach 197.88 mg/L.According to the orthogonal experiment,the best optimization technology for getting dimethyl sulfoxide was extraction time of 1h,extraction temperature at 25℃,and solid to liquid at ratio of 1: 20.Under these conditions,the concentration of canthaxanthin could rise to 291.9 mg/L and increased by 47.51% compared to that before optimization.
