Abstract

The invention discloses a preparation method of astaxanthin and resveratrol-containing self-microemulsion particles. The preparation method comprises the following steps: at a temperature of 40-60 DEG C, carrying out mixed dissolving on a surfactant, caprylic / capric triglyceride and a co-emulsifier, so that a blank self-microemulsion is obtained; adding resveratrol and astaxanthin into the blank self-microemulsion, and uniformly stirring, so that an astaxanthin and resveratrol-containing self-microemulsion is obtained; adding hydroxypropyl methylcellulose into the astaxanthin and resveratrol-containing self-microemulsion, and uniformly stirring, so that a mixed suspended astaxanthin and resveratrol-containing self-microemulsion is obtained; and finally, adding microcrystalline cellulose, so that the astaxanthin and resveratrol-containing self-microemulsion is changed into solid granular powder, namely, astaxanthin and resveratrol-containing self-microemulsion particles. Through the way, the preparation method disclosed by the invention is simple, and no special high-energy-consumption production equipment is required in the process of preparation; obtained products effectively increase the solubility of astaxanthin and resveratrol in water, and improve the influence of stomach scattering and intestinal lipolysis; and the effective bioavailability is high.

Description

technical field [0001] The invention relates to the field of biopharmaceuticals, in particular to a method for preparing self-microemulsion particles containing astaxanthin and resveratrol. Background technique [0002] In ancient times, "immortality" was the dream pursued by countless people. In modern times, there are still countless people who hope to "stay young forever". In the field of life sciences, everyone calls the exploration of this issue "research on anti-aging" , it can be seen that people's research on anti-aging has never stopped from ancient times to the present. This is an eternal topic. As we all know, only by knowing what it is, can we know why it is, and only by knowing the mechanism of aging can we better study anti-aging. [0003] Aging is a multifactorial and complex comprehensive physiological change process, and it is an inevitable stage in the growth process of individuals. Studies have shown that after the age of 30 in humans, various organs, ce...
