Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gel candy preparation, and particularly relates to a multi-layer core natural polyphenol algal gel candy with antioxidant capacity for pets. BACKGROUND

[0002] With the development of society, the demand for healthy food in various fields is increasing. Compared with simple supplements or health drugs, obtaining health ingredients from food is a more popular health care method for consumers. Free radicals are harmful substances produced during the body's metabolism. They can attack cell membranes, proteins, DNA and other biological molecules, leading to cell damage and aging. Antioxidants can react with free radicals and neutralize their activity, thereby protecting cells from damage and slowing down the aging process. In addition, antioxidants can enhance the activity of immune cells and enhance the immune function of the body, helping the body to resist various diseases. For example, antioxidants can reduce the oxidative stress response of blood vessel walls and prevent arteriosclerosis. Antioxidants can also protect the eyes from damage caused by harmful light such as ultraviolet light and prevent eye diseases. At the same time, antioxidants can delay skin aging by reducing oxidative damage to skin cells and maintain skin health. Studies have shown that antioxidants can also reduce oxidative stress damage to the nervous system, helping to alleviate psychological problems such as anxiety and depression, and improve mental health. In summary, antioxidants are of great importance to maintaining the health of the body. By consuming foods rich in antioxidants, supplementing antioxidants or using antioxidant products, the body can effectively resist the invasion of free radicals and protect the body from various diseases.

[0003] At the same time, as people pay more and more attention to the health of their companion pets, pet antioxidant / aging food has become a new research and development direction for pet food. For example, Chinese patent CN107006714A provides a compound antioxidant formula milk powder for old dogs and a preparation method thereof. The antioxidant formula milk powder for old dogs adds natural plant extracts and VC with antioxidant activity to the formula milk powder for old dogs, and VC and VE can be complementary and coordinated, synergistic, to remove free radicals in the body of the old dog, slow down the aging of the old dog, and reduce oxidative damage, so that the old dog can live a comfortable old age. Therefore, the development of antioxidant pet food has important practical significance.

[0004] Gelatin candy is a kind of candy with high water content, softness, elasticity and toughness, which belongs to soft candy. The main characteristics of gelatin candy are transparent appearance, smooth and soft taste, and high elasticity, which is deeply loved by consumers. For example, a composite anti-aging gelatin candy for human body and its preparation method provided in Chinese invention patent (CN 112753838A) comprises white granulated sugar 40-60 parts, starch syrup 50-90 parts, composite food gum 20-35 parts, skimmed milk powder 5-15 parts, honey 10-15 parts, concentrated fruit and vegetable juice 10-15 parts, edible essence 10-15 parts, edible colorant 5-15 parts, plant polyphenol extract 5-10 parts, xylitol 8-13 parts, sweet-sour degree regulator 5-10 parts, and sugar powder 30-50 parts. The invention contains skimmed milk powder, which can supplement nutrients for the human body, and cooperate with multiple vitamins and minerals in the concentrated fruit and vegetable juice to clean the gastrointestinal tract, remove toxins, and enrich the taste of gelatin candy. The plant polyphenol extract and honey added in the formula have strong antioxidant effect, good health care effect, and can achieve the effects of weight loss and whitening.

[0005] In addition, gelatin candy can be mixed or combined with pet supplements that are difficult to dry, and then mixed with dry pet food (such as cat and dog food), and not easy to dirty the container, so as to enrich the taste of pet food and supplement health elements.

[0006] In the preparation method of the gel candy in the above-mentioned patent, the plant polyphenol extract is directly mixed with other raw materials, which is not conducive to the preservation and full effect of antioxidant ingredients. Plant polyphenols are a class of compounds widely present in plants and have various biological activities, such as antioxidant activity. In the food field, plant polyphenol extract is widely used to improve the quality and function of products. However, when the plant polyphenol extract is mixed with raw materials, there may be some disadvantages, as follows: stability problem: after mixing with some raw materials, the plant polyphenol extract may undergo chemical reactions, resulting in decreased stability. This may shorten the shelf life of the product or cause deterioration during use. Compatibility problem: the compatibility between different raw materials is an important factor to consider. When the plant polyphenol extract is mixed with some raw materials, compatibility problems may occur, resulting in uneven mixture, layering or precipitation, affecting the appearance and performance of the product. The applicant designs a multi-layer core natural polyphenol alginate gel candy for pets, which allows the natural polyphenol to be wrapped in the skin material prepared from alginate gel as a multi-layer core material, ensuring good preservation and rich taste of the candy. Alginate gel belongs to polysaccharide compounds, which can stimulate the differentiation, maturation and reproduction of various immune active cells (such as macrophages, T lymphocytes, B lymphocytes, etc.), restore and strengthen the immune system of the body. At the same time, they can also remove excess free radicals and have the effect of anti-lipid peroxidation, thereby improving the body's antioxidant and anti-free radical damage ability. Therefore, the synergistic effect of polysaccharides in the skin material and natural polyphenols in the core material can further enhance the antioxidant benefits. SUMMARY

[0007] The purpose of the present application is to overcome the shortcomings and deficiencies of the prior art and provide a multi-layer core natural polyphenol alginate gel candy for pets with antioxidant capacity. The technical solution adopted by the present application is as follows: In a first aspect, a multi-layer core natural polyphenol alginate gel candy for pets with antioxidant capacity is provided, which comprises a skin material and three layers of core material wrapped inside the skin material. By weight, the formula of the skin material includes: alginate gel (80-90%), coconut powder (1-5%), and potassium sorbate (0.05-0.1%); the structure and formula of the core material include: inner layer, middle layer, and outer layer, each layer is prepared by mixing only one of apigenin, quercetin, and luteolin (1-3%) with coconut powder (1-5%), and the natural polyphenols contained in the inner layer, middle layer, and outer layer are different from each other; For example: the inner layer core material contains apigenin (1-3%) and coconut powder (1-5%); the middle layer core material contains quercetin (1-3%) and coconut powder (1-5%); and the outer layer core material contains luteolin (1-3%) and coconut powder (1-5%).

[0008] Since each polyphenol affects the antioxidant pathway of the body differently, as a preferred, the ratio of polyphenols in the inner layer, the middle layer, and the outer layer is: apigenin: quercetin: luteolin = 1:1:1.

[0009] The gel candy is safe and has no side effects, and also gives the candy good mouthfeel and shape stability, facilitating consumption; and the raw materials used are all natural ingredients, without adding any chemical synthetic substances, harmless to the body, safe and reliable, without sucrose, and more easily accepted by consumers.

[0010] Among the above raw materials, apigenin, as a very strong metal ion chelator, can reduce the participation of metal ions in free radical reactions by chelating metal ions, thereby blocking the generation reaction of oxygen free radicals and reducing the generation of oxygen free radicals. In addition, apigenin can also inhibit lipid peroxidation reaction, further exerting its antioxidant effect. This antioxidant effect helps to reduce the damage of oxygen free radicals to the body and delay the aging of the body.

[0011] Quercetin can complex with superoxide anion, iron ions, etc., reducing the generation of free radicals, thereby achieving a strong antioxidant effect. Increasing the intake of foods rich in quercetin, such as apples, green tea, oranges, pears, and various green vegetables, can supplement the body's need for antioxidant substances.

[0012] Luteolin is a natural flavonoid compound, which exists in the form of glycoside in many plants, such as whole leafed chenopodium, chili pepper, wild chrysanthemum, honeysuckle, perilla, etc.

[0013] In the antioxidant process, apigenin, quercetin, and luteolin in the natural composite polyphenol interact with catalase (KatA and C694_02495), cytochrome P450 family (CYP3A4, CYP1A1, CYP1B1, CYP3A5, CYP1A2), hydroxylase (Solyc11g066580.1.1), and monooxygenase (Solyc03g115220.2.1).

[0014] Catalase and Antioxidation: Catalase is a key enzyme in the antioxidant defense system of organisms, playing a crucial role in the process of eliminating hydrogen peroxide to avoid oxidative stress. Catalase is a marker enzyme of peroxisomes, protecting cells from the toxicity of H2O2 and preventing the further production of highly toxic hydroxyl radicals. Therefore, catalase plays an important role in the antioxidant process and is an important part of the body's antioxidant defense system. It can reduce the formation of free radicals and peroxidized lipids, playing an important protective role in the body. This protective effect not only helps maintain normal cell function, but also helps prevent various diseases related to oxidative stress, such as cardiovascular disease, cancer, etc. In summary, catalase and antioxidant are closely related, and it provides effective antioxidant protection for the body by decomposing hydrogen peroxide and reducing the formation of free radicals.

[0015] Cytochrome P450 and Antioxidation: Cytochrome P450 is a group of heme-coupled monooxygenase superfamily, which plays a variety of important roles in the body, one of which is involved in the antioxidant process. When the oxidative stress state in cells is too high, cytochrome P450 enzymes can reduce the degree of oxidative damage to cells through their antioxidant effect. This means that cytochrome P450 can neutralize free radicals, reduce their damage to cell structure and function, and thus protect cells from oxidative stress. On the other hand, when the oxidative stress state in cells is low, cytochrome P450 enzymes can increase the degree of oxidative reactions in cells through pro-oxidation. This balance is crucial for maintaining the stability of cell metabolism and physiological function. In maintaining human health and preventing disease, the antioxidant effect of cytochrome P450 cannot be ignored.

[0016] Hydroxylases and Antioxidation: Hydroxylases have some relationship with antioxidant; this relationship is mainly reflected in the contribution of hydroxylases to antioxidant mechanisms in metabolic processes. In terms of antioxidant, the role of hydroxylases may not be directly neutralizing free radicals, but indirectly achieving antioxidant effect by regulating the metabolism of bioactive substances. For example, some hydroxylases are involved in the synthesis and decomposition of hormones, which may have antioxidant or pro-oxidant effects. By regulating the levels of these hormones, hydroxylases can affect the redox state of the body and thus resist oxidative stress. It should be noted that the role of hydroxylases in antioxidant may vary depending on the specific enzyme species, substrates and biological environment. In summary, there is a certain relationship between hydroxylases and antioxidant.

[0017] The relationship between monooxygenases and antioxidant mainly lies in that monooxygenases can catalyze the monooxygenation of some substances, thereby playing a certain role in the antioxidant process. Monooxygenases are a class of enzymes that can catalyze the addition of an oxygen atom to the substrate molecule, and are widely involved in various metabolic processes in organisms. In terms of antioxidant, some monooxygenases can catalyze the synthesis or activation of some antioxidant substances, thereby enhancing the antioxidant capacity of organisms. These antioxidant substances can scavenge free radicals in the body, reduce oxidative stress, and protect cells from damage. In addition, monooxygenases can also be involved in some metabolic pathways related to antioxidant. For example, some monooxygenases can catalyze the oxidative metabolism of fatty acids, cholesterol and other substances, preventing the excessive accumulation of these substances in the body and triggering oxidation reactions. By regulating these metabolic pathways, monooxygenases help maintain the redox balance in organisms and protect cells from oxidative damage. In summary, there is a certain relationship between monooxygenases and antioxidant.

[0018] As a preference, the algal gel is an algal gel of kelp or an algal gel of porphyra, or a mixture of both.

[0019] Among the above raw materials, kelp polysaccharide is a widely existing natural high molecular polysaccharide. In Asia, artificial breeding of kelp is very common, and the yield is also very large. Therefore, artificial breeding of kelp in Asia has become the main raw material for extracting algal gel, so that kelp polysaccharide has the advantages of economy and easy availability compared with other algal gels. Kelp gel has excellent thickening, stability, water retention, gelation, emulsification, film formation and other properties.

[0020] Porphyra polysaccharide can be used as thickening agent, adhesive, stabilizer, etc., and has the characteristics of low fat, high dietary fiber, etc. Therefore, it has been favored in the field of food processing for a long time.

[0021] In a second aspect, a multi-layer core natural polyphenol algal gel candy for pets with antioxidant capacity is also provided, which includes the above-mentioned multi-layer core natural polyphenol algal gel candy for pets. The pet includes small and medium-sized mammals such as cats, dogs, and mice. The polyphenol (core material) can supplement the antioxidant components in the pet diet, avoid insufficient intake of nutritional components, and delay the aging of pets and improve the life quality of pets.

[0022] The pet multi-layer core natural polyphenol algal gel candy provided by the present application combines natural polyphenol as a multi-layer core material with algal gel and other raw materials as a skin material to prepare a gel candy with smooth taste and rich nutrition. The candy has strong antioxidant capacity, the skin (polysaccharide) plays a physical barrier role, can reduce the direct effect of adverse factors in the external environment on the active groups of phenolic substances, effectively reduces the contact of phenolic substances with the outside world, thereby reducing the damage to the active groups; secondly, the skin (polysaccharide) has a stabilizing effect: the interaction between polysaccharide and phenolic substances can form a stable complex, which can enhance the stability of phenolic substances and prevent the decomposition or oxidation of the active groups due to environmental changes; finally, the skin (polysaccharide) can adjust the release speed of phenolic substances: the wrapping effect of polysaccharide can also adjust the release speed of phenolic substances, by controlling the release speed, the action time of phenolic substances in the body can be prolonged, and the active groups can be prevented from being damaged due to rapid release.

[0023] On the other hand, the multi-layer core material avoids the compatibility problem that may occur, avoids uneven mixture, stratification or precipitation, and the combination of the above-mentioned skin and multi-layer core material can effectively remove free radicals in the body and delay aging.
