The invention relates to the field of foods, and particularly relates to a blueberry eye-protecting biscuit containing lutein and a preparation method thereof.

Background

The eye is the most important organ in human sense, and about 80% of the knowledge in the brain is acquired by the eye. The eye includes tissues such as the wall of the eyeball, the lumen and contents of the eye, nerves, blood vessels, and the like. The eyeball wall is mainly divided into an outer layer, a middle layer and an inner layer. The outer layer is composed of cornea and sclera and is also called fibrous layer. 1/6 is a clear cornea, and the rest 5/6 is a white sclera, commonly known as "white eye". The outer layer of the eyeball plays a role in maintaining the shape of the eyeball and protecting intraocular tissues. The cornea is a transparent portion of the anterior portion of the eyeball through which light is injected into the eyeball and is transmitted as a transparent wafer. The ciliary body is anterior to the root of the iris, posterior to the choroid, lateral to the sclera, and medial to the equator of the lens by zonules. The choroid is located between the sclera and the retina. The blood circulation of the choroid nourishes the outer retina, which contains abundant pigments that act as a light-blocking dark chamber, the inner retina.

In recent years, with the wide application of various electronic products and the change of living habits and environments of people, the incidence of eye diseases rises year by year, which seriously affects the eye health of people and is also more and more concerned by people in wide society. The long-term watching of a computer screen, the frequent movement of a watching point, the flickering of pictures and the long-term maintenance of one operation posture are main causes of visual fatigue of office workers.

In addition, it is not easy for people to actively supplement components or food with the effects of improving eyesight and protecting eyes on the dietary structure, because people always choose the components or food with the effects of improving eyesight and protecting eyes according to the eating habits and preferences of people when eating meals, and the importance of the components or food intake with the effects of improving eyesight and protecting eyes is not the same, therefore, the inventor thinks that the components or food with the effects of improving eyesight and protecting eyes are made into attractive biscuits or snacks with rich taste and rich nutrition to be a skillful concept, so that people are not forced to change the life or the eating habits, and the components or food with the effects of improving eyesight and protecting eyes which people do not want to actively eat is introduced into the daily diet of people.

Blueberries, also known as Vaccinium uliginosum, black bean (great Khingan), Diospyros kaki (great Khingan, Illicun), Diguo, dragon fruit, clam fruit (Jilin), Naja (Mongolian language), Giere, Uygur (Orenchun), and the like, are perennial low shrubs of Vaccinium of Ericaceae, and are one of the five healthy fruits recommended by world food and agricultural organizations. The blueberry fruit contains rich nutrient components, especially anthocyanin, and has good nutrition and health care effects, and also has the functions of preventing cranial nerve aging, strengthening heart, resisting cancer, softening blood vessels, enhancing human immunity and the like. The anthocyanidin in fructus Myrtilli can promote regeneration of rhodopsin in retinal cell, prevent severe myopia and retinal detachment, and improve vision. Meanwhile, the anthocyanin has the capability of accelerating the regeneration of the rhodopsin, which is an indispensable component for ensuring good vision.

Vitamin B1 is converted into thiamine pyrophosphate (also known as a co-carboxylase) in vivo, and is involved in the metabolism of sugars in vivo. Thus, in the absence of vitamin B1, sugar oxidation in the tissue is affected. Vitamin B1 also has the effect of inhibiting cholinesterase activity, and in the absence of vitamin B1, the enzyme activity is too high, so that acetylcholine (one of neurotransmitters) is largely destroyed to affect nerve conduction, which may cause gastrointestinal diseases, hair dryness, hypomnesis, cramp (muscle spasm), and considering the fusion effect of vitamin B, it should be added properly.

Vitamin B2, also called riboflavin, is directly related to energy generation, promotes growth and development and cell regeneration, improves vision, participates in vivo biological oxidation and energy generation, in vivo redox reaction and energy generation, participates in the process of converting tryptophan into nicotinic acid and converting vitamin B2 into pyridoxal phosphate, participates in vivo antioxidant defense system, and improves the adaptive capacity of the organism to environmental stress. In view of the fusion of vitamin B, appropriate addition is also required.

Vitamin B6 binds to phosphate in vivo to pyridoxal phosphate or pyridoxamine phosphate. Vitamin B6 can also be used as a coenzyme of various enzymes, participate in the metabolism of various amino acids, promote the absorption of amino acids and the synthesis of proteins, is a substance essential for cell growth, can also promote the metabolism of fat, participate in the synthesis of neurotransmitters and the synthesis of hemoglobin, and has an influence on normal reproductive function.

Vitamin B9: when the cell proliferates, the DNA is used as a raw material for DNA replication, participates in cell proliferation, reproduction, heme synthesis and the like, and is beneficial to generating new cells.

Vitamin B12 is also called cobalamin and is the only vitamin containing metal in human body. Take part in the metabolism of carbon units in vivo in the form of coenzymes. Nucleic acid and protein synthesis can be affected by increasing the availability of folic acid, thereby promoting the development and maturation of red blood cells. Vitamin B12 is also involved in choline synthesis, and the absence of choline affects fat metabolism and produces fatty liver. Vitamin B deficiency 12: causing megaloblastic anemia, nervous system damage, and hyperhomocysteinemia.

Vitamin C: can be used for preventing cataract. Cataract is a common eye disease of the old at the present stage, and can cause complete blindness and reading disorder when the cataract is serious, thereby affecting daily life. The formation of cataract is caused by oxidation of crystal, and vitamin C can inhibit the oxidation, and has protective effect when taken daily. In addition, administration of vitamin C can protect the liver.

Optionally, the vitamin comprises at least one of vitamin a, vitamin B1, vitamin B2, vitamin B3, vitamin B5, vitamin B6, vitamin B9, vitamin B12, vitamin C, vitamin E, vitamin P.
