Description

Technical Field

[0001] This invention relates to an eye-protecting soft capsule containing a compound of lycopene and lutein, and its manufacturing process. It pertains to a process for compounding and encapsulating lycopene and lutein into soft capsules, belonging to the field of health food technology. Specifically, it relates to an eye-protecting soft capsule containing a compound of lycopene and lutein, which improves the bioavailability and stability of fat-soluble components by optimizing the ingredient ratio and manufacturing process, employing high-speed emulsification and antioxidant protection technologies to achieve more efficient retinal protection and relieve eye fatigue, and its manufacturing process. Background Technology

[0002] With the development of the information society, prolonged use of electronic devices such as computers and mobile phones has become the norm in people's daily lives and work, leading to increasingly common eye problems such as eye strain, dry eye syndrome, and macular degeneration. To meet public concerns about visual health, a large number of soft capsule nutritional supplements with eye protection as their main function have appeared on the market, with common ingredients including lutein, DHA algal oil, and vitamin E. Among them, lutein, as an important component of the macula of the retina, is widely used because it can filter blue light and reduce photo-oxidative damage to the retina. However, existing eye-protecting soft capsule products still have significant shortcomings in terms of formulation design and technological implementation. On the one hand, most products have a relatively simple ingredient structure and lack active substances such as lycopene, which can synergistically work with lutein to resist oxidation and protect the optic nerve, resulting in a limited mechanism of action. On the other hand, the solubility and bioavailability of fat-soluble components in conventional plant oil carriers are low, and optimized lipid systems such as MCT oil and algal oil have not been introduced to improve absorption efficiency. In addition, some products lack systematic design in the process links such as antioxidant protection, capsule forming, and drying control, resulting in poor product stability and consistency.

[0003] Publication No. CN117919190A discloses an eye-protecting lutein soft capsule. The soft capsule comprises contents and a capsule material. The contents are made from the following raw materials in parts by weight: 4-15 parts lutein oil; 1-5 parts blueberry powder; 0.5-3 parts bilberry extract; 1-5 parts taurine; 1-5 parts β-carotene; 1-5 parts zinc citrate; 40-80 parts vegetable oil; and 5-15 parts mono- and diglyceride fatty acid esters. The capsule material comprises 5-15 parts mono- and diglyceride fatty acid esters; 40-65 parts vegetable oil; 5-20 parts glycerin; and 30-50 parts purified water. The preparation method involves preparing a premix, the contents solution, and the capsule material, and then compressing the contents and capsule material into lutein soft capsules. The lutein soft capsule of this invention enhances the antioxidant effect of the product, improves the stability of easily oxidized components such as lutein, and better exerts its medicinal value. However, the aforementioned eye protection software package does not contain lycopene and lacks antioxidant components that work synergistically with lutein, which may result in a relatively simple mechanism of action. Secondly, its production process is relatively simple and does not mention antioxidant protection treatment or low-temperature drying and shaping processes, which may affect the stability and consistency of the product.

[0014] The difference between this embodiment and Embodiment 1 is as follows: The production process of the eye-protecting soft capsule containing a compound of lycopene and lutein involves weighing 6.0g of lutein ester, 3.0g of lycopene, and 0.3g of vitamin E, mixing them to form the oil phase; weighing 15.0g of gelatin and 12.0g of glycerin, adding them to 37.5g of deionized water, and dissolving them in a 50°C water bath to form the wall material solution; and then adding Tween-80. 0.4g was stirred evenly to obtain an aqueous phase. The oil phase was slowly added dropwise to the aqueous phase. The emulsifier was used to emulsify at 10,000 rpm for 10 minutes using a high-speed shear emulsifier. The emulsion was pre-cooled in an ice-water bath for 20 minutes while stirring to keep it stable. The emulsion was filled and shaped using a rotary soft capsule production equipment to ensure that each soft capsule weighs 600mg. During the drying process, the temperature was controlled at 25℃ and the relative humidity was controlled at 35%. The capsules were allowed to stand for 48 hours to ensure that the soft capsules were formed evenly and that the active ingredients remained stable. After inspection and approval, the product was packaged to obtain 30 eye protection soft capsules per bottle. Example 3

[0015] The difference between this embodiment and Embodiment 1 is as follows: The production process of the eye-protecting soft capsule containing lycopene and lutein is as follows: 5.5g of lutein ester, 2.8g of lycopene, 4.5g of DHA algal oil, and 0.4g of vitamin E are weighed and mixed to form an oil phase. 13.0g of gelatin and 10.4g of glycerin are weighed and added to 33g of deionized water. The mixture is dissolved in a 55°C water bath to form a wall material solution. 0.5g of Tween-80 is added and stirred evenly to obtain an aqueous phase. The oil phase is slowly added dropwise to the aqueous phase. The mixture is emulsified for 8 minutes at 9000rpm using a high-speed shear emulsifier. The emulsion is pre-cooled in an ice-water bath for 15 minutes. The emulsion is kept stable during stirring. The soft capsule is filled using a rotary soft capsule production equipment. Each soft capsule weighs 750mg. The design of lutein and lycopene in a mass ratio of 2:1 enables the synergistic effect of the two carotenoids, enhancing the antioxidant effect and comprehensively protecting the retina from photo-oxidative damage. The eye-protecting soft capsules contain 0.05% to 0.5% black pepper extract, which can enhance the eye-protecting effect by improving the bioavailability of carotenoids, promoting the absorption of fat-soluble components; The design of a DHA algal oil to medium-chain triglyceride mass ratio of 1:1-1.5 optimizes the lipid carrier system, improves the absorption efficiency of components such as lutein and lycopene, and enhances their bioavailability. The soft capsules are fortified with natural antioxidants, such as rosemary extract or tea polyphenols, which can effectively delay the oxidation of active ingredients, improve the storage stability of the product, and ensure that the product remains active for a long time. The addition of 1% to 3% taurine to the eye-protecting soft capsules provides additional protection for the optic nerve, relieves eye fatigue, and helps enhance the function and health of retinal cells. The eye-protecting soft capsules contain zinc, specifically zinc gluconate or zinc sulfate, which promotes the synthesis of rhodopsin and maintains normal visual function, especially improving night vision. By optimizing the ingredient ratios and production processes, and employing high-speed emulsification and antioxidant protection technologies, the bioavailability and stability of fat-soluble components can be improved, thereby achieving more efficient retinal protection and relieving eye strain.
