Description

Technical Field

[0001] The invention belongs to the technical field of food, and in particular relates to a preparation method and application of an eye-protecting oral liquid. Background Art

[0002] Eye fatigue is a common eye disease. It causes dry eyes, sore eyes, blurred vision and even decreased vision, which directly affects people's work and life. Eye fatigue is mainly caused by people's reduced blinking frequency when they concentrate on watching TV, computers or mobile phones and other electronic products, resulting in a corresponding decrease in tear secretion. Eye fatigue can also cause and aggravate various eye diseases. Common causes include abnormal refraction, excessive eye convergence and abnormal eye development.

[0003] The closest existing patent is a red wolfberry blueberry effervescent tablet and its preparation method (CN201711461090.4). The raw materials of this patent are wolfberry powder, blueberry powder, sea buckthorn powder and grapefruit powder. Ginger extract and soy protein are not used, but auxiliary materials such as maltodextrin, sorbitol, oligofructose, xylitol and PEG are added.

[0004] The present invention adopts modern high-tech means, and combines Guizhou's original ecological edible and medicinal high-quality green materials such as blueberry, sea buckthorn and ginger, with blueberry as the main material, to produce a modern industrial food that provides balanced and comprehensive nutrition to eye cells, maintains eye health, and promotes the healthy growth of children, thereby filling the gap in market demand. Summary of the invention

[0005] The purpose of the present invention is to provide a preparation method and application of an eye protection oral liquid, which is a modern industrial food that provides balanced and comprehensive nutrition for eye cells, maintains eye health, and promotes the healthy growth of children. The liquid is suitable for people with visual fatigue, especially for teenagers with visual fatigue.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The invention discloses an eye protection oral liquid, which is prepared by weight components: 3.5 to 7.0 parts of blueberry liquid, 1.5 to 6.0 parts of roxburghii liquid and 0.5 to 2.5 parts of ginger extract.

[0008] The aforementioned eye protection oral liquid is calculated by weight components: 4.5 to 6.5 parts of blueberry liquid, 2.5 to 4.5 parts of sea buckthorn liquid and 0.7 to 1.2 parts of ginger extract.

[0009] Specifically, the aforementioned eye protection oral liquid is calculated by weight components: 5.0-6.0 parts of blueberry liquid, 3.0-4.0 parts of sea buckthorn liquid and 0.7-1.0 part of ginger extract.

[0010] The preparation method of the aforementioned eye protection oral liquid is carried out according to the following steps:

[0011] (1) taking blueberries, washing them, squeezing the juice at room temperature, filtering them, and pasteurizing and sterilizing them to obtain a liquid, that is, a blueberry liquid, which is refrigerated for later use;

[0012] (2) taking the original fruit of Rosa roxburghii, cleaning it, squeezing the juice at room temperature, filtering it, and pasteurizing and sterilizing it to obtain a liquid, that is, Rosa roxburghii liquid, which is refrigerated for later use;

[0013] (3) taking ginger, washing it, and then squeezing the juice at room temperature, separating it by gravity centrifugation to obtain ginger extract, and refrigerating it for later use;

[0014] (4) Weigh blueberry liquid, roxburghii liquid, and ginger extract according to the formula ratio, first mix the blueberry liquid and roxburghii liquid, then add the ginger extract, mix well, bottle, pasteurize, and package to obtain the finished product.

[0015] In the above step (1), the pasteurization temperature is first kept at 80°C for 20 minutes, then raised to 100°C and kept for 10 minutes, and the refrigeration temperature is -4 to -10°C.

[0016] In the above step (2), the pasteurization conditions are: keeping at 80°C for 20 minutes, then heating to 100°C for 10 minutes, and the refrigeration temperature is -4 to -10°C.

[0017] In the aforementioned step (3), the centrifugal speed is 3000 to 4000 r / min; and the refrigeration temperature is -4 to -10°C.

[0018] In the above step (4), after bottling, the pasteurization sterilization conditions are as follows: keeping the temperature at 80°C for 8 to 12 minutes, then heating to 90°C for 3 to 8 minutes, and finally heating to 95°C for 3 to 8 minutes;

[0019] Specifically, in the aforementioned step (4), the pasteurization sterilization conditions after bottling are as follows: keeping the temperature at 80°C for 10 minutes, then heating to 90°C for 5 minutes, and finally heating to 95°C for 5 minutes;

[0020] The application of the above-mentioned eye protection oral liquid in the preparation of food for preventing and treating children's visual fatigue.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) In the present invention, blueberries are rich in anthocyanins, which have an effect on eye protection, can effectively remove free radicals, effectively inhibit enzymes that damage eye cells, promote blood circulation in the eyes, protect eyesight, and relieve dry eyes; while roxburghii is rich in vitamin C, vitamin P and SOD, it can effectively remove free radicals in the body while supplementing vitamin C in the body, blocking the attack of free radicals on the eyes. Ginger extract is a nutrient absorption promoter, which can promote cerebral blood flow and oxygen metabolism, promote adolescents to absorb anthocyanins in blueberry liquid and vitamin C in roxburghii liquid, help activate retinal function, promote rhodopsin regeneration in retinal cells, improve eye microcirculation, and relieve visual fatigue. The characteristic of the eye protection oral liquid is that for adolescent students and people who use computers and mobile phones more often, each person can supplement a certain amount of blueberry roxburghii eye protection oral liquid every day to supplement anthocyanins and play a certain eye protection role.

[0023] (2) Blueberry juice, sea buckthorn juice, and ginger extract are used to make an eye protection oral liquid. The oral liquid can meet the needs of different groups of people and avoid the use of unnecessary additives. It ensures a sweet and sour taste and avoids the sandy feeling of chewing tablets.

[0024] (3) The processing and purification of blueberry juice, sea buckthorn juice, and ginger extract are performed at room temperature, which is sufficient to ensure the presence of the active nutritional functional components and proteins in the above raw materials.

[0025] (4) In order to ensure the product quality of the oral liquid, the food GMP standards are adopted in production conditions, and the specifications are strictly implemented, clean operations are carried out, single-bottle packaging is used, and the product can be consumed immediately after opening to eliminate contamination and ensure safety.

[0026] (5) Synergistic effect

[0027] Blueberry is the protagonist of this formula. It is the king because blueberry is high in anthocyanins, a type of polyphenol that can activate retinal function, promote the regeneration of rhodopsin in retinal cells, improve eye microcirculation, and relieve visual fatigue.

[0028] Seabuckthorn is the assistant to blueberry, and is the king of VC, VP and SOD native to my country. It has a more powerful antioxidant function, and when combined with blueberry, it can assist and ensure that blueberry can promote the regeneration of rhodopsin in retinal cells and relieve visual fatigue. Ginger is rich in gingerol and other ingredients, which can promote cerebral blood flow, increase oxygen supply, and promote the body's absorption of the effective functional ingredients of blueberry and seabuckthorn. It also has the function of refreshing the brain and improving learning and work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
