In this study, factors affecting the extraction yield of carotenoids from dried shrimp waste by organic solvents have been studied. The results showed that the solvent ratio hexane: acetone = 3: 1 gave the highest carotenoid yield. At this ratio of solvent’s mixture, the carotenoid yield reached highest at temperature 60 C after 2 hours extraction, which was µg/g raw shrimp waste (.) (ratio of solvent to raw material 3/1). Ultrasound or vortexing gave higher extraction yield than in static conditions, which was fold to fold increase, respectively. At the ratio of solvent: dried shrimp waste = 4: 1, the amount of carotenoids recovered at 60 C for 2 hours with vortexing increased to µg/g. However, if the shrimp waste was hydrolyzed with Alcalase at 50 C for 4 hours before extraction by solvent, the amount of recovered carotenoids achieved µg/g of raw material. | Optimization of conditions for carotenoid extraction from shrimp waste using organic solvent
