In this study, ultrasonic- and microwave-assisted extraction was performed to recover astaxanthin (ASX) from samples of F. merguiensis shrimp and P. maeoticus Gammarus using three solvents: organic solvent, vegetable oil and ionic micro emulsion. The microemulsions were evaluated in terms of density, conductivity and particle size. The microemulsion had a density of 0.9715 g/cm, a conductivity of 312 µSiemens and an average particle size of 15.8 nm. The results showed that for both samples, the ionic microemulsion solvent performed better in ASX extraction and the F. merguiensis shrimp produced more total carotenoids compared to the other sample. In both methods, the recovery efficiency of ASX increased with increasing amount of solvent. Ultrasonic-assisted extraction better preserved the structure and antioxidant properties of ASX, but the microwave method showed higher extraction efficiency.
在本研究中，采用超声和微波辅助萃取法，使用三种溶剂（有机溶剂、植物油和离子微乳液）从墨吉对虾和梅奥蒂克钩虾样本中回收虾青素（ASX）。对微乳液的密度、电导率和粒径进行了评估。该微乳液的密度为0.9715 g/cm，电导率为312微西门子，平均粒径为15.8纳米。结果表明，对于两个样本，离子微乳液溶剂在虾青素萃取方面表现更好，并且与另一个样本相比，墨吉对虾产生的总类胡萝卜素更多。在两种方法中，虾青素的回收效率均随溶剂量的增加而提高。超声辅助萃取能更好地保留虾青素的结构和抗氧化性能，但微波法显示出更高的萃取效率。
