Abstract

The invention discloses a method for efficiently removing peculiar smell of astaxanthin by applying a supercritical technology, belonging to the technical field of astaxanthin production. The method comprises the following steps: S1, analyzing peculiar smell substances of astaxanthin oil through a solid-phase micro-extraction method; S2, based on the types of the peculiar smell substances, employing a supercritical method deodorization technology for deodorization, adding astaxanthin oil to be deodorized into supercritical equipment, and conducting pressurization through a pressurization unit of equipment, and then conducting heating through microwave heating equipment. According to the invention, the to-be-deodorized astaxanthin oil in a liquid state is firstly deodorized through a supercritical CO2 solvent by the supercritical method, then the astaxanthin oil is dried into the astaxanthin powder, and the astaxanthin oil in a solid state is deodorized again through supercritical CO2 gas by the supercritical method, and various measures are combined, so the effect of removing the peculiar smell of the astaxanthin is greatly improved; and the problems that an existing supercritical technology is single in peculiar smell removing measure, not ideal in effect and prone to damage caused by astaxanthin are solved.

Description

technical field [0001] The invention belongs to the technical field of astaxanthin production, in particular to a method for efficiently removing the peculiar smell of astaxanthin by applying supercritical technology. Background technique [0002] Astaxanthin is a ketone carotenoid, red solid powder, fat-soluble, insoluble in water, soluble in organic solvents, it widely exists in the biological world, especially in aquatic animals such as shrimp, crab, fish and birds In the feathers of species, it plays the role of coloration. [0003] Astaxanthin is a chain-breaking antioxidant with strong antioxidant capacity. It can remove nitrogen dioxide, sulfide, disulfide, etc., and can also reduce lipid peroxidation, effectively inhibiting free radicals. At the same time, it has various physiological effects such as inhibiting tumor occurrence, enhancing immunity, and eliminating free radicals in the body. It has a good therapeutic effect on skin cancer caused by ultraviolet rays, ...
