[0037] Collagen peptide is 5-20%, natural antioxidant extract is 1-10%, plant melatonin is 0.1-2%, vitamin complex is 0.5-5% and the rest is other auxiliary ingredients;

[0038] Among them, the molecular weight of collagen peptides ranges from 2000-5000 Daltons;

[0039] Other supporting ingredients include prebiotics, dietary fiber and natural flavors.

[0040] In a specific embodiment of the present invention, collagen peptide is 5-20%, preferably 10-15%; natural antioxidant extract is 1-10%, preferably 3-7%; plant melatonin is 0.1-2%, preferably 0.5-1.5%; vitamin complex is 0.5-5%, preferably 1-4%; other auxiliary ingredients are the remainder, wherein the molecular weight range of collagen peptide is preferably 2000-5000 Daltons to ensure its good bioavailability and absorption efficiency. At the same time, the addition amount of natural antioxidant extract is intended to provide sufficient antioxidant capacity to support skin health, while plant melatonin helps to improve sleep quality, and vitamin complex can further enhance the comprehensive health care effect of the product. Other auxiliary ingredients include but are not limited to prebiotics, dietary fiber, natural flavors, etc., which are used to improve taste and increase functional ingredients.

[0041] For details, please refer to Figure 1, natural antioxidant extract uses green tea extract and grape seed extract mixed in a weight ratio of 1:1.

[0042] In this embodiment: the natural antioxidant extract is selected from one or more of green tea extract, grape seed extract, and blueberry extract. It is preferred to use green tea extract and grape seed extract mixed in a weight ratio of 1:1, because both extracts are rich in catechins and proanthocyanidins, have strong antioxidant properties, can effectively scavenge free radicals, and promote the renewal of skin cells, thereby achieving the effect of beauty and skin care.

[0043] For details, please refer to Figure 1 , plant-based melatonin uses oats from cereals.

[0044] In this embodiment: plant melatonin is in grains, seeds, mushrooms or other plant materials, preferably oats in grains, because oats are rich in melatonin precursors, which help regulate the body's biological clock and improve sleep quality. At the same time, oats are rich in vitamin B group and other minerals, which are beneficial to health; plant melatonin is a substance naturally present in grains, seeds, mushrooms and other plant materials, which plays an important role in regulating the body's biological clock and improving sleep quality. Among these plant sources, oats are the preferred ingredients because of their high content of melatonin precursors. Melatonin precursors in oats, such as tryptophan, are key components in melatonin synthesis, and melatonin helps improve sleep by regulating the body's sleep-wake cycle. Oats not only help regulate sleep, but also provide rich vitamin B group, including vitamin B1, B2, B3, B6 and B9, which are essential for the health of the nervous system, energy metabolism and the formation of red blood cells. In particular, vitamin B6, which plays an important role in the synthesis of melatonin, further enhances the effect of oats in promoting sleep. In addition, oats are also rich in minerals, including magnesium, zinc and iron, which are essential for maintaining good health. Magnesium helps relax muscles and relieve stress, zinc is essential for immune system function, and iron is an important component of hemoglobin, which helps prevent anemia. The high dietary fiber content in oats, especially the soluble fiber beta-glucan, not only increases satiety, but also has a positive effect on weight control and maintaining healthy eating habits. It can also lower cholesterol and is beneficial to cardiovascular health. Therefore, incorporating oats into your daily diet can not only help improve sleep quality, but also provide the body with necessary nutrients to help maintain overall health, especially in the fast-paced modern life and generally poor sleep quality. As a natural sleep assistant and nutritional treasure, the value of oats is self-evident.

[0045] For details, please refer to Figure 1, prebiotics use inulin, the added amount of inulin is 2-5%, dietary fiber uses apple fiber, the added amount of apple fiber is 1-3%, and natural flavor uses vanilla extract, and the added amount of vanilla extract is 0.1-0.5%.

[0046] In the present embodiment: In the formulation design of beauty and health food, in addition to the main active ingredients, other auxiliary ingredients also play an important role, which can enhance the overall effect and user experience of the product. These auxiliary ingredients include prebiotics, dietary fiber, natural spices, etc., each of which has a unique function. Inulin, as a preferred prebiotic, is added in an amount controlled between 2-5%, which can effectively promote intestinal health. Inulin is a natural fructan, mainly derived from chicory root, which can selectively stimulate the growth of beneficial intestinal flora, such as bifidobacteria and lactic acid bacteria, thereby improving the balance of intestinal microecology, enhancing intestinal barrier function, and helping to maintain the health of the digestive system. The addition of dietary fiber comes from apple fiber, and its addition amount is 1-3%, which has a positive effect on helping digestion. Apple fiber is a soluble fiber that can absorb water and swell, increase stool volume, thereby promoting intestinal peristalsis, helping to prevent constipation, and can also lower cholesterol, which is beneficial to cardiovascular health. In addition, the addition of natural flavors is also an important means to enhance the flavor of the product. The selected vanilla extract, added at a rate of 0.1-0.5%, can not only provide a pleasant taste, but also increase the naturalness of the product. Vanilla extract is extracted from vanilla beans and contains a variety of aromatic components. Its natural aroma can mask the unpleasant taste that may be brought by other ingredients, making the product more delicious and improving consumer acceptance and satisfaction. The careful selection and proportioning of these auxiliary ingredients can not only enhance the nutritional value of the product, but also enhance the market competitiveness of the product and meet consumers' dual pursuit of health and deliciousness. Through such a formula design, beauty and health foods can not only provide necessary nutritional supplements, but also bring better sensory experience while maintaining physical health.

[0047] For details, please refer to Figure 1 , the molecular weight of collagen peptides ranges from 2500-4000 Daltons.

[0048] In this embodiment: collagen peptide is a small molecule peptide extracted from collagen by a specific technology, and its molecular weight range is usually between 2000-5000 Daltons, and the preferred molecular weight range is 2500-4000 Daltons. This preferred molecular weight range is based on scientific research and human absorption efficiency, because collagen peptides within this range can be more effectively absorbed and utilized by the human body. Collagen is the main structural protein of tissues such as skin, bones and joints. With the increase of age, collagen in the human body is naturally lost, causing the skin to lose elasticity and luster, and wrinkles and relaxation. By supplementing collagen peptides, the collagen required by the skin can be effectively supplemented, thereby improving skin elasticity and gloss. The smaller molecular weight makes collagen peptides easier to be decomposed and absorbed in the digestive system, can directly enter the blood circulation, transport to the dermis of the skin, stimulate fibroblasts to synthesize new collagen, enhance the supporting structure of the skin, and reduce the formation of wrinkles and fine lines. In addition, collagen peptides in this molecular weight range can also increase the water content of the skin, maintain the moist state of the skin, and further enhance the overall appearance of the skin. Studies have shown that collagen peptides with a molecular weight of 2500-4000 Daltons have the highest bioavailability and can maximize their beauty and skin care effects. Therefore, when choosing collagen peptide products, consumers should pay attention to the molecular weight of the product and choose products within this preferred range to ensure the best absorption and skin care benefits. At the same time, the supplementation of collagen peptides should also be combined with a healthy lifestyle and eating habits to achieve a beauty effect that improves both the inside and the outside. Supplementing collagen peptides through scientific methods can help people slow down the skin aging process and keep the skin young.

[0049] For details, please refer to Figure 1 , also includes trace elements zinc and selenium, with zinc content of 0.5-2mg / 100g and selenium content of 0.1-1mg / 100g.

[0050] In the present embodiment: the trace elements zinc and selenium contained in food are important nutrients for maintaining skin health and improving body immunity. Zinc is a multifunctional trace element, which is essential for human health. Its content in food is 0.5-2mg / 100g, and the preferred content range is 1-1.5mg / 100g. Zinc participates in the activity of multiple enzymes in the body and is a key factor in cell growth, division and repair. Especially for skin health, zinc can promote wound healing, maintain skin barrier function, and reduce the occurrence of skin inflammation and acne. In addition, zinc is also involved in the synthesis of collagen, which helps to maintain the elasticity and firmness of the skin and prevent skin aging. Selenium is a powerful antioxidant that can help resist the damage of free radicals and protect cells from the influence of oxidative stress. The selenium content in food is 0.1-1mg / 100g, and the preferred content range is 0.3-0.8mg / 100g. Selenium is equally important for maintaining skin health. It can protect the skin from environmental factors such as ultraviolet rays and reduce the risk of skin sunburn and photoaging. At the same time, selenium can also enhance the function of the immune system and improve the body's resistance to disease, which is essential for maintaining overall health. Scientific studies have shown that the right amount of zinc and selenium intake can significantly improve the health of the skin, enhance the skin's natural defenses, and reduce the occurrence of skin problems. Therefore, in the daily diet, it is necessary to ensure that the food contains appropriate levels of zinc and selenium. By properly matching food, these trace elements can be effectively supplemented to keep the skin healthy and young. When choosing health foods, consumers should pay attention to the zinc and selenium content in the product and choose those products with content within the preferred range to ensure that they can get enough trace elements to play their role in maintaining skin health and improving immunity. Through such nutritional supplements, you can effectively support the health of the body and improve the quality of life.

[0054] S3, add other auxiliary ingredients, adjust the pH value to 6.5-7.5, and the pH value is 6.8-7.2;

[0055] S4. Sterilize at 100-120°C for 10-20 minutes;

[0056] S5. Pack after cooling. Pack after the temperature drops to room temperature to avoid heat damage.

[0057] In this embodiment: the collagen peptide is mixed with water, heated to 60-80°C and stirred evenly, preferably the heating temperature is 65-75°C, and the stirring time is 10-15 minutes; natural antioxidant extract, plant melatonin and vitamin complex are added, and stirring is continued for 5-10 minutes; other auxiliary ingredients are added, and the pH value is adjusted to 6.5-7.5, preferably the pH value is 6.8-7.2; sterilization treatment is carried out at 100-120°C for 10-20 minutes, preferably the treatment time is 15 minutes; packaging is carried out after cooling, and the cooling temperature is preferably reduced to room temperature before packaging to avoid thermal damage.

[0058] For details, please refer to Figure 1 In step S3, a stabilizer is added, wherein food grade potassium sorbate is used as the stabilizer, and the addition amount of food grade potassium sorbate is 0.05-0.1%.

[0059] In the present embodiment: in the production process of beauty and health food, it is crucial to ensure the stability of the product and extend the shelf life. Therefore, in step S3, in addition to the main active ingredients and auxiliary ingredients, a stabilizer is also added to increase the shelf life of the product. The selection and use of stabilizers have a significant impact on preventing the product from deteriorating during storage and maintaining product quality and effect. In this step, food-grade potassium sorbate is preferably used as a stabilizer, and its addition amount is controlled between 0.05-0.1%. Potassium sorbate is a widely used food additive with excellent preservative properties. It can effectively inhibit the growth of molds, yeasts and aerobic bacteria, and prevent the product from being corrupted and deteriorated due to microbial activity. The antibacterial mechanism of potassium sorbate is to inhibit its growth and reproduction by interfering with the metabolic process of microorganisms, especially affecting the absorption of amino acids by microorganisms. Since the antibacterial effect of potassium sorbate is not affected by pH value, it can maintain good stability in acidic, neutral and alkaline environments, so it is suitable for various types of health foods. When adding potassium sorbate, it is crucial to strictly control the amount added to ensure that the preservative effect can be achieved without affecting the health of consumers. The addition amount of 0.05-0.1% is within the food safety standard range, which can effectively extend the shelf life of the product while ensuring the safety of consumers. In addition, as a food-grade stabilizer, the safety of potassium sorbate has been widely scientifically studied and recognized by food safety agencies. Consumers can safely eat health foods containing an appropriate amount of potassium sorbate. By adding potassium sorbate to the product, it can not only extend the shelf life of the product, but also maintain the stability of the product during storage and transportation, ensuring that consumers can obtain the expected nutritional supplements and beauty effects when purchasing and using the product. Therefore, in the production process of beauty and health foods, adding an appropriate amount of potassium sorbate as a stabilizer is a key step to improve product quality and market competitiveness.

[0060] For details, please refer to Figure 1 After step S5, the method further includes performing secondary packaging under aseptic conditions, wherein the packaging uses vacuum packaging technology.

[0061] In the present embodiment: in the production process of beauty and health food, the secondary packaging after step S5 is completed is a key link, which directly affects the stability and shelf life of the product. In order to further enhance the stability of the product and ensure that the quality of the product during storage and transportation is not affected, step S5 is followed by secondary packaging under aseptic conditions. In this step, vacuum packaging technology is preferably used to effectively extend the shelf life of the product by reducing the contact between the product and oxygen. Vacuum packaging technology is an efficient packaging method that creates a low oxygen or oxygen-free environment by extracting the air in the packaging container, thereby slowing down the oxidation process of the food and the growth rate of microorganisms. Vacuum packaging under aseptic conditions can minimize the risk of contamination of the product during the packaging process and maintain the purity and nutritional value of the product. During the packaging process, the product is first filled into a pre-sterilized container, and then the air in the container is extracted by a vacuum packaging device, and it is quickly sealed to prevent oxygen and other external factors from adversely affecting the product. This packaging method is particularly important for health foods containing easily oxidizable ingredients, such as products containing sensitive ingredients such as unsaturated fatty acids and vitamins. Vacuum packaging can effectively prevent the oxidation of these ingredients and maintain the activity of the product. In addition, vacuum packaging can prevent the growth and reproduction of microorganisms, because most microorganisms need oxygen to survive, and the vacuum environment can inhibit their activity, thereby extending the shelf life of the product. The preferred vacuum packaging technology not only improves the stability of the product, but also reduces the use of preservatives, which meets consumers' pursuit of natural and healthy food. Through this packaging method, the product can better maintain its original color, aroma, taste and nutritional value during storage and transportation, providing consumers with higher quality products. Therefore, in the production of beauty and health foods, the use of vacuum packaging technology under sterile conditions is an important measure to improve the overall quality of the product and enhance market competitiveness.
