Abstract

The invention provides a deep eutectic solvent microemulsion extraction system and a method for extracting astaxanthin. The deep eutectic solvent microemulsion extraction system is prepared from, by mass, 10-50% of a deep eutectic solvent, 45-80% of a compound surfactant and 5-40% of cyclohexane. The method for extracting the astaxanthin comprises the following operation steps of preparing the deep eutectic solvent microemulsion extraction system; adding shrimp shell powder into the deep eutectic solvent microemulsion extraction system, and carrying out a reaction for extraction; conducting solid-liquid separation to obtain a liquid supernatant; adding a back-extractant into the liquid supernatant for back-extraction; conducting solid-liquid separation; cleaning an obtained solid, and thenconducting drying to obtain the astaxanthin powder. The deep eutectic solvent microemulsion extraction system has a high solubility to the astaxanthin, and the structure of the astaxanthin cannot bedamaged; the operation of extracting the astaxanthin from shrimp shells through the deep eutectic solvent microemulsion extraction system is simple, the extraction time is short, and the extraction rate is high.

Description

technical field

[0001] The invention relates to the technical field of chemical extraction, in particular to a deep eutectic solvent microemulsion extraction system and a method for extracting astaxanthin. Background technique

[0002] The antioxidant activity of astaxanthin has been proven to be 10 times that of zeaxanthin, lutein, canthaxanthin and beta-carotene, and 100 times that of alpha-tocopherol. In addition, astaxanthin quenches a single oxygen molecule and scavenge free radicals inside the cell membrane, thereby resisting lipid oxidation, improving the function of the immune system and the order of gene expression. Not only that, astaxanthin also has significant anti-inflammatory, anti-diabetic, cardiovascular disease prevention, immune regulation and anti-cancer functions. In addition, astaxanthin also has the effect of improving the rhythm regulation and hypoglycemic effect of hepatic metabolic disorder caused by high fat. The superior biological activity and o...
