Preparation process for astaxanthin microcapsule

Abstract

The invention discloses a preparation process for an astaxanthin microcapsule. The process comprises the following steps: adding water into a wall material, carrying out mixing to obtain a wall material solution and then adding an emulsifier with a concentration of 6% so as to prepare a wall material emulsifier solution; then adding an astaxanthin oil solution with a concentration of 3% and carrying out violent stirring so as to prepare an astaxanthin emulsifier; then carrying out secondary dispersion stirring at a speed of 30000 r / min for 1 min and then ternary dispersion stirring at a speed of 30000 r / min for 1 min; and finally carrying out spray drying so as to prepare the astaxanthin microcapsule. According to the invention, since the water-soluble wall material is used for microencapsulation of astaxanthin, stability is effectively improved, loss is reduced, the utilization rate of astaxanthin is substantially increased, and an application scope is broadened.

Description

[0001] technical field [0002] The invention belongs to the technical field of microcapsules, and in particular relates to a preparation process of astaxanthin microcapsules. [0003] Background technique [0004] Astaxanthin is a red ketone carotenoid with a strong ability to capture free radicals, which can effectively prevent oxidative damage to tissues, cells, and DNA, and has a strong activity of scavenging free radicals and quenching active oxygen , has a super antioxidant effect, and is the strongest antioxidant found in nature by humans so far, and its antioxidant activity far exceeds the existing antioxidants. Its antioxidant capacity is 6000 times that of vitamin C; 550-1000 times that of natural VE; 10 times that of natural β-carotene; therefore, it is known as "super vitamin E" and "healthy soft gold". Astaxanthin also has various physiological functions such as inhibiting tumor occurrence and enhancing immunity, and is widely used in the fields of feed additi...
