Problems solved by technology

However, fucoxanthin has the problems of low absorption rate and poor stability, and taking it directly leads to a significant reduction in its vision protection effect
At present, the improvement of fucoxanthin's targeted transport to optic organs through protein self-assembly and its application in vision-protecting functional foods have not yet been reported.

Abstract

The invention belongs to the field of food, and specifically discloses a functional food for improving the antioxidant capacity of visual organs and a preparation method thereof. The functional food for improving the antioxidant capacity of visual organs contains 10 to 50 parts by weight of fucoxanthin-protein complex, 5 to 30 parts by weight of polyphenol extract, 1 to 5 parts by weight of clematis extract, and 1 to 5 parts by weight of abalone shell extract. 1-5 parts by weight of compound, 0.1-1 part by weight of zinc gluconate, 0.1-1 part by weight of degraded sulfated polysaccharide, and the rest are water and / or solid filler auxiliary materials. The functional food for improving the antioxidant capacity of visual organs provided by the present invention contains fucoxanthin-protein complexes, polyphenol extracts, clematis extracts, abalone shell extracts, zinc gluconate, and degraded sulfated polysaccharides. It can promote the targeted transportation of fucoxanthin metabolites (fucoxanthol) in the visual organs, and the above components are designed according to the proportion, which can play a synergistic protective effect on the visual organs, thereby significantly improving the visual organs. Anti-oxidative stress capacity.

Description

technical field [0001] The invention belongs to the field of food, and specifically discloses a functional food for improving the antioxidant capacity of visual organs and a preparation method thereof. Background technique [0002] The eye is the most active organ of human physiological metabolism. Due to the need for vision, the eye (especially the retina) is exposed to high oxygen pressure, high polyunsaturated fatty acids, and high light concentration for a long time, and is extremely vulnerable to oxidative stress damage. At the same time, due to the needs of modern life and work methods, video terminal equipment such as broadband mobile phones, computers, and TVs have become very popular. Long-term exposure to light radiation environments has further aggravated eye fatigue and stress damage to visual organs. As the myopia rate of children and adolescents and the incidence of eye diseases such as cataract and age-related macular degeneration continue to rise, visual heal...
