a Effect of solvent to sample ratio and power on carotenoid extracted from shrimp with ionic microemulsion, b Effect of solvent to sample ratio and power on carotenoid extracted from shrimp with organic solvent), c Effect of solvent to sample ratio and power on carotenoid extracted from shrimp with oil solvent, d Effect of solvent to sample ratio and power on carotenoid extracted from gammaros with ionic microemulsion, e Effect of solvent to sample ratio and power on carotenoid extracted from gammaros with organic solvent, f Effect of solvent to sample ratio and power on carotenoid extracted from gammaros with oil solvent. Red color indicates the highest and blue color indicates the lowest amount of carotenoids.
