Embodiment

[0031] A method for preparing a composition for relieving visual fatigue and preventing myopia, characterized in that the method comprises:

[0032] (1) Weigh each component according to the ratio, 60 parts of sorbitol, 50 parts of maltodextrin, 4 parts of blueberry powder, 2.5 parts of zeaxanthin, 1 part of lutein, 0.3 parts of β-carotene, fish oil microcapsules 0.2 parts of powder, 0.007 parts of vitamin A; the ratio of meso (3R, 3'S)-zeaxanthin and zeaxanthin is 1:35.

[0033] (2) Dissolve vitamin A with an appropriate amount of edible ethanol, and stir at a constant temperature of 35-45°C for 30 minutes; dissolve 10-20 parts of maltodextrin in distilled water to prepare a saturated solution for use; Evenly add vitamin A solution to the saturated maltodextrin solution at a rate of 1-2 drops per second, and stir at a constant temperature of 40-45°C for 1-2h, cool to room temperature, and filter after standing for 6-9h; wash with ether 2-3 times, spray drying to obtain vitam...

Abstract

The invention belongs to the field of healthy food and particularly relates to a food composition with effects of relieving asthenopia and preventing myopia and a preparation method of the food composition. The food composition is prepared from components as follows: sorbitol, maltodextrin, blueberry powder, zeaxanthin, lutein, beta carotene, fish oil microcapsule powder and vitamin A. The defectsthat the vitamin A is poor in stability and prone to oxidation are overcome, so that the vitamin A has stable property and good fluidity, and the effects of the composition on relieving asthenopia and preventing myopia can be well played.

Description

technical field [0001] The invention belongs to the field of health food, and in particular relates to a food composition capable of relieving visual fatigue and preventing myopia and a preparation method thereof. Background technique [0002] Eye fatigue, also known as visual fatigue, is a common eye disease. It causes dry eyes, eye astringency, eye soreness, blurred vision and even vision loss directly affects people's work and life. The main cause of visual fatigue is that the eyeball is in the state of searching and gazing for a long time, resulting in damage to the structure and function of visual cells, excessive consumption of visual cells, and insufficient supply of nutrients required by them, resulting in long recovery time for the macula and retina. Nutrients in the visual cells mainly include lutein and vitamin A. If the supply of these two substances is insufficient, the visual cells will not be able to function properly, resulting in rapid vision loss and metamo...
