Description

Technical Field

[0001] The present invention relates to the technical field of skin care and health care, and in particular to a composite protein peptide multidimensional nutritional composition and a preparation method thereof. Background Art

[0002] In today's society, with the rapid development of the economy and the significant improvement of people's quality of life, people's attention to personal care and health has reached an unprecedented level. In this context, skin care products are not only a basic need for daily beauty care, but also an important symbol of modern people's pursuit of high-quality life. The main functions of skin care products have evolved from traditional functions of protecting the skin from external damage and nourishing the skin to promote its health, to beautifying the skin and improving personal image, fully satisfying people's dual desire for beauty and health.

[0003] However, with the advancement of industrialization and the popularization of urban life, environmental pollution is becoming increasingly serious. External factors such as pollutants in the air and ultraviolet radiation pose a severe challenge to the skin. At the same time, the accelerated pace of modern life, the increase in work pressure, and the differences in personal eating habits and work and rest patterns have led to a trend of diversified skin problems. These skin problems include but are not limited to: dry skin due to water loss, skin sensitivity caused by damaged barrier function, accelerated skin aging due to oxidative stress, spots formed by pigmentation, and acne caused by unbalanced oil secretion. These problems not only affect the health of the skin, but also seriously reduce people's quality of life and self-confidence.

[0004] Collagen is the main structural protein of the skin. With age and the influence of the external environment, the collagen in the skin will gradually be lost, causing sagging skin and wrinkles. Collagen peptides, as the hydrolyzate of collagen, can replenish the collagen needed by the skin, thereby enhancing the elasticity and firmness of the skin, making the skin smoother and more elastic. However, there are many types of collagen, and different types of collagen have different effects. There is no relevant report in the field on how to identify and select collagen to cope with various skin problems and promote absorption.

[0005] Therefore, how to provide a composite protein peptide multidimensional nutritional composition and a preparation method thereof to achieve beauty and skin care, supplement collagen, increase the residence time in the body, and promote skin absorption is a difficult problem to be solved urgently in this field. Summary of the invention

[0006] In view of this, the present invention provides a composite protein peptide multidimensional nutritional composition and a preparation method thereof, so as to solve the problems that existing skin care products have single effects, low absorption and utilization rate of effective ingredients, and poor skin improvement effects.

The antioxidants in it can inhibit the deposition of melanin, improve skin tone, fade spots, and make the skin firmer and more elastic; antioxidants such as vitamin C, vitamin E, anthocyanins can neutralize free radicals in the body and reduce the damage of oxidative stress to cells.

[0017] Angelica is rich in vitamin C, vitamin E and flavonoids, and has excellent antioxidant effects, which can help the skin eliminate free radicals and reduce skin aging.

[0018] Lycium barbarum is rich in antioxidant active substances such as Lycium barbarum polysaccharides, carotenoids, vitamin E, selenium and flavonoids. These ingredients work together to make Lycium barbarum have a significant antioxidant effect. Lycium barbarum polysaccharides are an important antioxidant component in Lycium barbarum. They can also regulate the nervous system and play a calming and soothing role. Taking them before bed will make it easier for people to fall asleep and help improve sleep quality.

[0019] The main active ingredients of Schisandra chinensis are biphenylcyclooctenes, such as Schisandrin, Schisandrin B, Schisandrin C, etc. Schisandra chinensis can not only play an antioxidant role by capturing oxygen free radicals, but also increase the activity of antioxidant enzymes in cells to remove free radicals, and has a good protective effect on the skin. Schisandra chinensis can also improve the problems of palpitations, insomnia and dreaminess caused by Yin and blood deficiency, lack of nourishment to the mind, and lack of heart and kidney.

[0020] Pectinase can degrade pectin in plant cell walls and release nutrients encapsulated in the pectin, such as vitamins, minerals, etc., thereby improving the nutritional value of the product; the addition of pectinase helps these ingredients to be better released and absorbed.

[0021] Bovine collagen peptides can be absorbed and utilized by the human body and converted into collagen needed by the skin, thereby improving skin quality, enhancing skin elasticity and firmness, and reducing the formation of fine lines and wrinkles. It can also provide nutritional support for the skin, making it rosy and shiny.

[0022] Fish collagen peptides can nourish the skin, enhance the activity of collagen in the skin, keep the skin elastic and lustrous, and reduce the formation of wrinkles and fine lines; it can also inhibit the formation of melanin, promote skin metabolism to a certain extent, reduce spots, make the skin whiter, and achieve the effect of whitening and removing spots; it can also relieve body fatigue and help improve the overall state of the body.

[0023] The donkey-hide gelatin in donkey-hide gelatin peptides has a certain blood-tonifying effect, which can prevent pale complexion, improve sleep quality, and thus improve skin condition; the amino acid components in donkey-hide gelatin peptides can also promote the repair and regeneration of skin cells, improve skin quality, and make the skin smoother and more delicate. For problems such as rough and dry skin, donkey-hide gelatin peptides can also play a significant role in improving them.

[0024] Niacinamide can promote metabolism, inhibit the transfer of melanin to epidermal cells, reduce pigmentation, and at the same time reduce melanin production to achieve whitening and spot removal; it can also enhance the skin's barrier function, improve the skin's water retention capacity, and keep the skin hydrated; it can remove free radicals in the body, regulate the skin's oil secretion, and improve skin inflammation, improve skin texture, and make the skin smoother and more delicate.

[0025] GABA has a small molecular weight and can pass through the stratum corneum to bind to the GABA type A receptor, open the chloride ion channel, neutralize the potential difference, inhibit neuronal excitation, help reduce the stimulation of muscle cells, and achieve the effect of reducing wrinkles; it can also stimulate the synthesis of hyaluronic acid, increase the moisture retention and elasticity of the skin,

[0026] Sodium ascorbate and GABA also have the function of scavenging free radicals and can slow down skin aging.

[0027] Polydextrose is a dietary fiber that can enhance the number and activity of beneficial bacteria in the intestines, inhibit the excessive reproduction of harmful bacteria, and regulate the balance of intestinal microecology; by improving intestinal health and promoting metabolism in the body, polydextrose can affect the absorption of effective components.

[0028] It can be seen from the above technical solutions that, compared with the prior art, the present invention has the following beneficial effects:
