Description

Preparation method of Sanhuang eye-protecting candy tablet
Technical Field
The invention belongs to the technical field of preparation of eye-protecting candy pieces, and particularly relates to a preparation method of a Sanhuang eye-protecting candy piece.
Background
In recent years, the aging process of population in China is aggravated, the number of netizens is rapidly increased, the problems of dry eyes, acid distension, blurred vision, vision degradation, pathological changes, blindness and the like are highlighted, people are enabled to pay more attention to eye health, and meanwhile, the demands of people on eye health supplements are also accelerated.
Children and teenagers can prevent myopia. The incidence rate of myopia of teenagers in China reaches 67%, and the deficiency of nutrition for vision development is removed from the influence of the increase of academic pressure and electronic equipment, and is also an important factor for influencing the vision of teenagers.
Executive and mobile phones can relieve asthenopia. The crowd is exposed to high-energy blue light such as mobile phones and computers for a long time every day, so that the problems of eye fatigue, itching, ache, digital vision syndrome and the like are easily caused, and further symptoms such as deepening myopia, double vision and incapacity of concentrating attention are caused.
The eye health is not neglected in the silver hair family. China gradually walks into an aging society, and age-related macular degeneration becomes one of important reasons affecting the eye health of the aged, so that serious vision damage and even blindness are caused, and the age-related eye health diseases can be killed in a cradle in early stage through timely nutrition intervention.
Tagetes, carrots, pumpkin and the like are recognized as "eye protection golden partner", and are rich in carotenoid bioactive substances such as lutein, zeaxanthin and beta-carotene. The combination of lutein and zeaxanthin can filter harmful blue light, protect eyes from oxidative stress and free radical injury, reduce macula damage, and play roles in maintaining normal vision of retina, preventing senile maculopathy, preventing retinitis pigmentosa, etc.; beta-carotene is absorbed and converted into vitamin A (also known as retinol or anti-xerophthalmia factors) through the small intestine in the human body, and the vitamin A has the function of maintaining normal visual functions in dark places, is beneficial to relieving the influence of ultraviolet rays and high-energy visible light, and simultaneously stabilizes the transportation of lutein and zeaxanthin to eyes and indirectly promotes the health of retina and macular area. The human body cannot synthesize lutein, zeaxanthin and beta-carotene by itself and must be supplemented by food.
