Description

Technical Field

[0001] The present application relates to the field of food processing, and more specifically, to a gel candy having the effects of relieving visual fatigue and protecting eyesight and a production process thereof. Background Art

[0002] Visual fatigue, also known as eye fatigue, is a common ophthalmological disease. Its main manifestation is visual impairment, such as blurred vision and double vision when using the eyes at close range, and a long time for the eyes to adapt when alternating between near and far objects. The surface symptoms of the eyes include drowsiness, fear of light, soreness or pain in the eyeball and around the eye socket, tearing, foreign body sensation, dry eyes, etc.

[0003] With the acceleration of modern life and the popularity of electronic products, people spend a long time in front of computer, mobile phone and other screens, which causes the eyes to be in a state of tension for a long time, which easily leads to problems such as visual fatigue, dryness, myopia, etc. In this context, people begin to seek various methods to relieve visual fatigue and protect eyesight. Although traditional eye protection methods such as doing eye exercises and looking into the distance have certain effects, they are difficult to meet the needs of modern people's fast-paced life.

[0004] For example, the Chinese patent application publication number CN1524448A discloses a nutritional health food for protecting eyesight, which includes 120-270 μg of retinol, 0.32-0.72 mg of riboflavin, 3.2-7.2 mg of vitamin E, 3.6-5.4 mg of zinc, 400-600 μg of β-carotene, and 32-48 mg of aminoethanesulfonic acid. This technical solution produces a product that relieves visual fatigue by supplementing nutrients from the outside. For another example, a Chinese patent application with publication number CN107050192A discloses a composition for protecting eyesight, including sodium vitamin C, vitamin A, lutein, taurine, scented tea fruit extract, etc. Lutein is added to the above technical solutions for protecting eyesight, and lutein is an important component of the retina. Supplementing lutein can protect eyesight, absorb and filter high-energy blue light, reduce damage to the eyes, and help improve visual fatigue. However, due to the highly unsaturated molecular structure of lutein, it is unstable to light, heat and ultraviolet rays, and is easily degraded during processing and storage; and the content of lutein in food is relatively low, which is difficult to meet large demands.

[0005] As people pay more and more attention to eye health and personalized consumption demand grows, it is of great significance to develop gel candies that are well absorbed, more stable, and can significantly relieve visual fatigue and protect eyesight. Summary of the invention

[0006] In order to obtain a gel candy with better stability and the ability to effectively relieve visual fatigue and protect eyesight, the present application provides a gel candy with the ability to relieve visual fatigue and protect eyesight and a production process thereof.

[0007] In the first aspect, the present application provides a production process of a gel candy having the efficacy of relieving visual fatigue and protecting eyesight, which adopts the following technical solution: A production process of a gel candy having the effects of relieving visual fatigue and protecting eyesight, comprising the following steps: S1. Prepare materials: prepare walnut oil, lutein ester oil suspension, gelatin, sweet orange oil, carotene, sweetener, fruit powder mixture, glycerin, taurine and vitamin C, and set aside; S2. preparing a colloid mixture: adding gelatin, a sweetener and glycerin into water, heating and stirring to dissolve, and preparing a colloid mixture; S3, mixing walnut oil, lutein ester oil suspension, sweet orange oil and carotene to prepare an oil phase solution; S4, mixing the fruit powder mixture, taurine and vitamin C to prepare a powder mixture; S5, adding the powder mixture prepared in step S4 to the colloid mixture prepared in step S2, and then adding the oil phase solution in step S3, stirring and mixing to obtain a syrup liquid; S6, heating the prepared syrup liquid to 75-85° C., stirring, to obtain a colloidal solution; S7, shaping the obtained colloidal solution into pellets to obtain a gel candy prototype, and then drying to obtain a gel candy.

[0008] By adopting the above technical scheme, the gel candy raw materials provided by the present application are mainly added with walnut oil and lutein ester oil suspension. Walnut oil is rich in α-linolenic acid and Omega-3 fatty acids, has an antioxidant effect, can remove free radicals in the eyes, and protect the retina from oxidative damage. Walnut oil can also promote blood circulation, make the blood vessels of the eyes unblocked, and improve the sensitivity and clarity of the optic nerve, thereby relieving visual fatigue; and the lutein ester in the lutein ester oil suspension is an esterified form of lutein, which has higher bioavailability and stability. Lutein ester can also eliminate free radicals and prevent organ It can prevent age-related macular degeneration caused by aging, thereby protecting vision; more importantly, lutein esters are more stable than lutein at room temperature, and are not easily degraded by light, heat and oxygen, thereby maintaining the stability of its active ingredients during processing and storage; and lutein esters can be decomposed into lutein in the human body and absorbed and utilized, and the decomposition products of lutein esters are more easily utilized and absorbed by the human body, thereby improving their bioavailability. Lutein esters are widely present in marigold flowers and other plants, making the extraction and purification of lutein esters relatively easy and less costly; In addition, carotene and sweet orange oil are also added in the present application. Carotene is one of the important components of the photosensitive substances in the visual cells, which can enhance the sensitivity of the retina and improve vision. The supplement of carotene in candy can effectively relieve the visual fatigue caused by long-term use of the eyes; the components such as limonene and sabinene in sweet orange oil can relieve the tension of the eye muscles, thereby reducing visual fatigue and protecting vision; gelatin is the main molding agent of gel candy, and the sweetener gives the gel candy a sweet taste, while the fruit powder mixture is rich in vitamins and antioxidants, which helps to enhance the antioxidant stability and nutritional value of the product. Nutritional value, and taurine as a sulfur-containing amino acid can regulate the neurotransmitters in the retina, promote the metabolism and regeneration of retinal cells, and at the same time, taurine can enhance the antioxidant capacity of the eyes and protect the eyes from oxidative damage. Vitamin C as a powerful antioxidant can scavenge free radicals and protect the eyes from oxidative damage. Finally, the present application uses the addition of esterified lutein ester oil suspension in combination with walnut oil and other ingredients and antioxidant ingredients to relieve visual fatigue and protect vision, and the gel candy prepared in the present application has better stability and bioabsorption rate.

[0009] In addition, in the production process provided in the present application, the powder mixture containing taurine and vitamin C is first added to the colloidal mixture, so that the above active ingredients are evenly distributed in the candy. At the same time, the colloidal mixture containing gelatin provides a stable carrier for the above active ingredients, which helps to form a uniform continuous phase, making the candy more stable in taste and structure. After the colloidal mixture is mixed with the powder mixture, the oil phase mixture is added. The oil phase solution and the colloidal mixture form a tighter structure, which helps to prevent the candy from deformation or rupture during storage or transportation, and can also serve as a carrier to protect the active ingredients in the powder mixture from the external environment, thereby improving the stability of the candy.

[0010] Optionally, in step S5, when adding the oil phase solution, first add a total amount of 1 / 3-1 / 2 of the oil phase solution to form a preliminary emulsion, then ultrasonically treat the preliminary emulsion for 2-3 minutes, add the remaining oil phase solution, continue ultrasonicating for 3-5 minutes, and then stir to obtain a syrup liquid.

[0011] By adopting the above technical solution, when the oil phase solution is directly added, due to the poor compatibility of the oil phase solution with the water-soluble colloid mixture, a uniform dispersion system cannot be formed, resulting in difficulty in maintaining a stable form during the pellet forming process, irregular shape, uneven size, and subsequent stratification, water precipitation or deterioration, etc., resulting in reduced stability. Therefore, in the present application, part of the oil phase solution is first added to the colloid mixture to preliminarily disperse the oil phase to form a preliminary emulsion, thereby reducing the difficulty of subsequent mixing. After the preliminary emulsion is formed, ultrasonic waves are used to add the remaining oil phase solution. The cavitation effect of ultrasonic waves can generate strong microjets and shock waves, which effectively break up the agglomeration of oil droplets, promote the uniform dispersion of the oil phase in the colloid mixture, avoid the formation of large agglomerates of the oil phase in the colloid mixture, and improve the uniform dispersion of the final product.

[0012] Optionally, the lutein ester oil suspension is prepared by the following method: Lutein ester powder is added into epoxidized linseed oil, a dispersant is added and stirred, shearing and emulsification is performed, and then a suspending agent is added and homogenized to prepare a lutein ester suspension.

[0013] By adopting the above technical scheme, lutein esters will degrade under high temperature, strong acid, strong alkali and oxygen conditions. In the subsequent preparation steps of the gel candy in the present application, the gelling treatment is carried out at high temperature, resulting in the subsequent degradation of the lutein esters in the candy of the present application, a decrease in the content of active substances, and a decrease in the efficacy of relieving visual fatigue. Therefore, in the present application, lutein esters are added in the form of dispersion in epoxidized linseed oil. Epoxidized linseed oil, as a natural antioxidant and protective agent, effectively isolates the effects of adverse factors such as light, heat, and oxygen on lutein esters, thereby slowing down their degradation rate. In addition, epoxidized linseed oil can also be used as a carrier to disperse the lutein esters more evenly in the product, thereby improving its bioavailability.

[0014] Optionally, the suspending agent comprises hydroxypropyl β-cyclodextrin, hydroxyethyl cellulose and amino hydroxyethyl cellulose in a mass ratio of 1:(1.5-2):(0.6-0.8).

[0015] By adopting the above technical scheme, the suspending agent in the present application selects a mixture of hydroxypropyl β-cyclodextrin, hydroxyethyl cellulose and amino hydroxyethyl cellulose in a specific ratio. The hydroxyl groups in hydroxypropyl β-cyclodextrin and hydroxyethyl cellulose can interact with the ester groups through hydrogen bonds to form hydrogen bonds, thereby increasing the stability of lutein esters in epoxidized linseed oil. On the other hand, the thixotropic property of hydroxyethyl cellulose forms a stable network structure in the oil suspension system. When subjected to force, the network structure is destroyed and its viscosity decreases, maintaining a certain fluidity, which is beneficial to subsequent processing. When standing still, the network structure will be reformed and the original stability will be restored. In this way, the hydrogen bond chemical action is combined to achieve The results show that lutein esters are stably suspended in epoxidized linseed oil; hydroxypropyl β-cyclodextrin has a cavity structure with internal hydrophobicity and external hydrophilicity. It is found that when hydroxypropyl β-cyclodextrin is added, its internal lipophilic part realizes the loading of lutein ester, and due to the interfacial tension between the hydrophilic part on the outside and the epoxidized linseed oil solution system, the lutein ester is stably suspended in the epoxidized linseed oil to form a more stable oil suspension. When the oil phase is subsequently mixed with the colloidal mixture, the hydrophilic end of the hydroxypropyl β-cyclodextrin is conducive to breaking the oil phase interface and mixing with the water phase, which is more helpful to improve the compatibility of the two phases and facilitate the subsequent uniform dispersion in the candy.

[0016] Optionally, the amino hydroxyethyl cellulose is prepared by the following method: Hydroxyethyl cellulose is dissolved in water, citric acid is added, and then spermidine is added, reacted at 45-55° C. for 2-3 hours, centrifuged and dried, and washed to obtain amino hydroxyethyl cellulose.

[0017] By adopting the above technical scheme, in the present application, spermidine is added to hydroxyethyl cellulose under acidic catalytic conditions as an amination agent, and spermidine contains multiple amino groups in its molecular structure, and its long-chain structure enables it to be used as an amination agent to achieve amino modification on hydroxyethyl cellulose. The long-chain structure of the formed amino-modified hydroxyethyl cellulose forms a network structure in the solution, providing steric hindrance for the lutein ester molecules to prevent them from aggregating and precipitating with each other; and the introduced amino functional groups form hydrogen bonds with the ester groups of the lutein ester molecules, which helps to stably adsorb the lutein ester molecules in the network structure of the amino-modified hydroxyethyl cellulose, thereby enhancing its suspension stability and protecting it from the adverse factors of high temperature and oxygen, which is beneficial to protecting its activity and can also be more evenly dispersed in the candy system to play a better role in protecting eyesight.

[0018] Optionally, the raw materials in step S1 are prepared according to the following weight parts: 45-60 parts of walnut oil, 30-45 parts of lutein ester oil suspension, 50-60 parts of gelatin, 20-30 parts of sweet orange oil, 5-15 parts of carotene, 15-20 parts of sweetener, 5-10 parts of fruit powder mixture, 20-30 parts of glycerin, 3-8 parts of taurine and 5-10 parts of vitamin C.

[0019] Optionally, in the step of preparing the lutein ester oil suspension, each raw material is added according to the following weight portions: 20-30 parts of lutein ester, 25-40 parts of epoxidized linseed oil, 2-5 parts of dispersant and 3-5 parts of suspending agent.

[0020] Optionally, in the preparation of amino hydroxyethyl cellulose, each raw material is added according to the following weight parts: 10-20 parts of hydroxyethyl cellulose, 15-25 parts of water, 3-5 parts of citric acid, and 1-3 parts of spermidine.

[0021] Optionally, the sweetener includes one or more of sorbitol, erythritol, and mogroside; The fruit powder mixture is selected from one or more of blueberry fruit powder, blood orange fruit powder and blackcurrant fruit powder.

[0022] Optionally, the sweetener comprises a mixture of sorbitol, erythritol and mogroside in a mass ratio of 1:(0.5-0.7):(0.1-0.2); The fruit powder mixture is a mixture of blueberry fruit powder, blood orange fruit powder and blackcurrant fruit powder in a mass ratio of 1:(0.6-0.8):(0.4-0.6).

[0023] By adopting the above technical solution and selecting the above sweetener and fruit powder mixture, the candy has a better taste and antioxidant performance, thereby having better stability and the effect of relieving visual fatigue and protecting eyesight.

[0024] In the second aspect, the present application provides a gel candy having the effect of relieving visual fatigue and protecting eyesight, which adopts the following technical solution: A gel candy with the effects of relieving visual fatigue and protecting eyesight is prepared by the preparation method.

[0025] By adopting the above technical scheme, the gel candy prepared by the production process of the present application retains more active ingredients, has better effects on eye fatigue and protecting eyesight, and has better stability.

[0026] In summary, this application has the following beneficial effects: 1. The present invention uses esterified lutein ester oil suspension in combination with walnut oil and antioxidants to relieve visual fatigue and protect eyesight, and the gel candy prepared in the present invention has better stability and bioabsorption rate; 2. Walnut oil and lutein ester oil suspension are mainly added to the raw materials of the gel candy provided by the present application.

Walnut oil can also promote blood circulation, make the blood vessels of the eyes unblocked, and improve the sensitivity and clarity of the optic nerve, thereby relieving visual fatigue; and the lutein ester in the lutein ester oil suspension is an esterified form of lutein, which has higher bioavailability and stability. Lutein ester can also eliminate free radicals, prevent the body from aging-induced It can prevent age-related macular degeneration of the retina, thereby protecting vision; more importantly, lutein esters are more stable than lutein at room temperature and are not easily degraded by light, heat and oxygen, thereby maintaining the stability of its active ingredients during processing and storage; and lutein esters can be decomposed into lutein and absorbed in the human body, and the decomposition products of lutein esters are more easily utilized and absorbed by the human body, thereby improving their bioavailability. Lutein esters are widely present in marigold flowers and other plants, making the extraction and purification of lutein esters relatively easy and less costly; 3. In the production process provided in the present application, a powder mixture containing taurine and vitamin C is first added to a colloidal mixture so that the above active ingredients are evenly distributed in the candy. At the same time, the colloidal mixture containing gelatin provides a stable carrier for the above active ingredients, which helps to form a uniform continuous phase, making the candy more stable in taste and structure.

[0038] Performance Testing 1. First, gel candies were prepared according to the methods in the examples and comparative examples of the present application, and the time for the colloid solution prepared in step S6 to undergo stratification or sedimentation was observed. The statistical results are shown in Table 1 below.

[0039] Table 1: Performance Testing Example 1 Example 2 Example 3 Example 4 Example 5 Stability / h 76 73 75 68 55 Test items Example 6 Example 7 Example 8 Comparative Example 1 Comparative Example 2 Stability / h 60 62 66 67 48 2. The gel candies prepared in the examples and comparative examples of the present application were tested for their effects on improving visual fatigue symptoms on subjects. Subjects aged between 20 and 40 were selected and divided into 10 groups, with 50 subjects in each group. The subjects ate the gel candies prepared in the present application twice at a specified time every day, one capsule each time, for one month. Statistics were collected based on the improvement effects of the gel candies of the present application on blurred vision, soreness or pain around the eyeballs and eye sockets, foreign body sensation, and dry eyes after long-term viewing. The statistical results are shown in Table 2 below.

[0040] Table 2: Combined with the test results in Table 1 and Table 2 above, the gel candies prepared in Examples 1-3 of the present application have a good improvement efficiency for eye fatigue, have the effect of relieving eye fatigue and protecting eyesight, and when the colloidal solution prepared in step S6 is relatively stable, it means that the oil phase solution in the colloidal solution and the colloidal mixture are mixed and dispersed more evenly, the raw material system is uniform, and the prepared gel candies are more stable. Referring to the test results of Example 1 and Example 4, when the oil phase solution is added to the colloidal mixture in Example 4, when it is directly added without adding in batches and with ultrasonic dispersion, the obtained colloidal solution system has poor compatibility with the colloidal mixture, and the final stability is poor, which is not conducive to the uniformity and stability of the product, and its effect of relieving visual fatigue is also reduced. Combined with the test results of Examples 5-8, when no suspending agent was added in Example 5, the lutein ester may be unevenly dispersed in the epoxidized linseed oil, resulting in a significant decrease in the stability of the final product. Referring to the test results of Examples 6 and 7, when hydroxypropyl β-cyclodextrin was not added to the suspending agent, its stability was poor. Combined with the test results of Example 8, when hydroxypropyl β-cyclodextrin was added to the suspending agent, its stability was improved. Referring to the test results of Comparative Example 1, when the lutein ester oil suspension in Comparative Example 1 was directly replaced with lutein ester, due to the influence of high temperature and oxygen environment in subsequent operations, the lutein ester was degraded, resulting in a decrease in the active ingredient, and the efficiency of relieving visual fatigue was significantly reduced. On the other hand, it may be due to the lack of the effect of the suspending agent, and the stability of the colloidal solution finally obtained was also reduced. When the colloidal solution was obtained by directly mixing and stirring the colloidal mixture with other raw materials in Comparative Example 2, its stability was also significantly reduced, and the effect of improving eye fatigue was also reduced.

[0041] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed. However, as long as it is within the scope of the claims of the present application, it shall be protected by the patent law.
