| Abstract: | In this paper,shrimp and crab waste was used as raw material for extraction of astaxanthin.The subcritical fluid extraction process was optimized by method of single-factor and orthogonal experiments.The results show that the best extraction reagent,temperature,pressure,static time and static cycle were dichloromethane,100 ℃,9.31~11.72 MPa,15 minutes and 2 times,respectively.Under the above optimum condition,the extraction ratio is 0.037 3%.Compared with the results of the traditional organic solvent extraction process,the extraction ratio in the subcritical fluid extraction process is 33.2% higher than that of the traditional process,and the processing time is reduced by 82.8%. |
