Technical Field

[0001] The invention relates to the technical field of pet additive processing, in particular to a functional food additive for beautifying pet hair and a preparation method thereof. Background Art

[0002] Pet feed, also known as pet food, was originally defined as high-end animal nutrition products specifically for pets, positioned between human diet and traditional livestock and poultry feed. The core function of this type of product is to provide pets with a comprehensive nutritional system required for basic physiological needs, growth support and health maintenance. Compared with traditional feeding methods, modern pet food has significant advantages: the use of scientifically proportioned nutrients, strict production standards and highly absorbable formula design not only ensures feeding convenience, but also effectively prevents specific diseases. It is worth noting that differentiated functional needs such as improving hair quality or enhancing immunity can be achieved by adding functional ingredients to products.

[0003] When people raise pets, the smoothness of the pet's hair is an important indicator. However, existing pet food additives do not have the function of beautifying hair. To ensure that the pet's hair is smooth, the pet needs to be bathed regularly, which increases the risk of the pet suffering from skin diseases. Summary of the invention

[0004] The purpose of the present invention is to provide a functional food additive for beautifying pet hair and a preparation method thereof, so as to solve the problem mentioned in the above background technology that in order to ensure that the pet hair is smooth, the pet needs to be bathed frequently, which increases the risk of the pet suffering from skin diseases.

[0005] To achieve the above object, the present invention provides the following technical solution: a functional food additive for pet hair beautification and a preparation method thereof, comprising:

[0006] The basic components of the composite additive include hair nutrients, synergistic enhancing ingredients and functional auxiliary materials, and the mass percentages thereof are: hair nutrients 50-65%; synergistic enhancing ingredients 25-35%; functional auxiliary materials 10-15%;

[0007] The hair nutrition agent includes fish oil extract, biotin, zinc chelate and vitamin B complex, and the mass ratio is: fish oil extract 15-20%; biotin 8-12%; zinc chelate 5-8%; vitamin B complex 10-15%;

[0008] The synergistic ingredients include methionine, cystine, green tea polyphenols and vitamin E, with the mass ratio being: methionine 10-15%; cystine 5-8%; green tea polyphenols 3-5%; vitamin E 3-5%;

[0009] The functional auxiliary materials include maltodextrin, silicon dioxide and pregelatinized starch, and the mass ratio thereof is: maltodextrin 6-10%; silicon dioxide 2-4%; pregelatinized starch 2-5%.

[0010] Preferably, the preparation method of the hair nutrition agent comprises the following steps:

[0011] ① Preparation of fish oil extract: select adipose tissue of deep-sea fish (such as salmon and sardines), remove impurities and chop into small particles, remove moisture through low-temperature freeze-drying to avoid high temperature destruction of active ingredients, keep the dried raw materials in a loose state for subsequent extraction, put the raw materials into an extraction kettle, introduce liquid CO2, adjust the pressure and temperature to a suitable range, make CO2 reach a supercritical state, continue extraction for several hours, reduce the pressure and temperature through a separation kettle, separate the fish oil and CO2, and collect high-purity Omega-3 fish oil;

[0012] ② Activation treatment of biotin: Mix high-purity biotin raw materials with a specific buffer solution and continuously stir in a constant temperature water bath to form a uniform colloidal solution. By controlling the reaction conditions, the biotin molecules are fully dispersed to enhance their biological activity. The colloidal solution is sent to the spray drying equipment, and the inlet and outlet temperatures are adjusted to quickly dry the solution into nano-scale particles. The final product is a loose powder, ensuring that the particle size is small and the water content is low;

[0013] ③Synthesis of zinc chelate: Dissolve zinc gluconate and lysine in deionized water in proportion, heat in a water bath and stir continuously to promote the chelation reaction, and judge the degree of reaction completion by observing the transparency of the solution. Centrifuge the reaction solution to remove unreacted impurities, collect the supernatant and freeze-dry it to obtain a white powdery zinc chelate;

[0014] ④ Preparation of vitamin B complex: Weigh multiple vitamin B ingredients in proportion, mix them evenly with anti-caking agents to ensure no caking, use a three-dimensional mixer to fully stir to make the ingredients evenly distributed, send the mixed powder into the fluidized bed equipment, spray the adhesive solution, and form fine particles in the flowing state. After granulation is completed, use light-proof sealed packaging to prevent the vitamins from oxidizing and becoming ineffective.

[0015] Preferably, the hair nutrient comprises fish oil extract, biotin, zinc chelate and vitamin B complex, and the mass ratio thereof is: fish oil extract 15-20%; biotin 8-12%; zinc chelate 5-8%; vitamin B complex 10-15%.

[0016] Preferably, the synergistic ingredients include methionine, cystine, green tea polyphenols and vitamin E, and the mass ratio thereof is: methionine 10-15%; cystine 5-8%; green tea polyphenols 3-5%; vitamin E 3-5%.

[0017] Preferably, the functional excipients include maltodextrin, silica and pregelatinized starch, and their mass ratio is: maltodextrin 6-10%; silica 2-4%; pregelatinized starch 2-5%.

[0018] Preferably, the zinc chelate is a stable complex formed by chemically combining zinc ions with organic ligands (such as amino acids). The zinc chelate is formed by chelating zinc gluconate and lysine in a molar ratio of 1:2 to form a zinc-lysine chelate, which directly participates in the synthesis of pet hair keratin, improving hair strength and luster.

[0019] Preferably, during the preparation of the vitamin B complex, 0.5-1% of the total amount of microcrystalline cellulose is added as an anti-caking agent, and it is stored in light-proof aluminum foil packaging.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: The additive of the present invention contains a hair nutrient, a synergistic component and a functional excipient. The active ingredients are significantly improved by fish oil and biotin. The zinc chelate is protected by amino acid coordination to avoid being destroyed by gastric acid, ensuring the synthesis efficiency of hair keratin. Methionine and cystine provide sulfur elements to promote keratin cross-linking. The vitamin B complex regulates the hair follicle metabolic cycle, supplemented by green tea polyphenols to scavenge free radicals and reduce hair loss caused by oxidative damage. Pregelatinized starch and maltodextrin optimize the fluidity of particle forming. Freeze-drying and light-proof packaging maintain the activity of vitamins, improving the luster and toughness of pet hair, reducing breakage and shedding. At the same time, the zinc chelate and the antioxidant system extend the healthy cycle of hair. After being eaten by pets, it can effectively improve the hair quality of pets, reduce the number of times pets take baths, and thus reduce the risk of pets suffering from skin diseases.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] An embodiment provided by the present invention: A functional food additive for beautifying pet hair and its preparation method, including,

[0023] The basic components of the composite additive include a hair nutrient, a synergistic component and a functional excipient, and their mass percentages are: hair nutrient 50-65%; synergistic component 25-35%; functional excipient 10-15%;

[0024] The hair nutrition agent includes fish oil extract, biotin, zinc chelate and vitamin B complex, and the mass ratio is: fish oil extract 15-20%; biotin 8-12%; zinc chelate 5-8%; vitamin B complex 10-15%;

[0025] The synergistic ingredients include methionine, cystine, green tea polyphenols and vitamin E, with the mass ratio being: methionine 10-15%; cystine 5-8%; green tea polyphenols 3-5%; vitamin E 3-5%;

[0026] The functional auxiliary materials include maltodextrin, silicon dioxide and pregelatinized starch, and the mass ratio thereof is: maltodextrin 6-10%; silicon dioxide 2-4%; pregelatinized starch 2-5%.

[0027] Furthermore, the preparation method of the hair nutrition agent comprises the following steps:

[0028] ① Preparation of fish oil extract: select adipose tissue of deep-sea fish (such as salmon and sardines), remove impurities and chop into small particles, remove moisture through low-temperature freeze-drying to avoid high temperature destruction of active ingredients, keep the dried raw materials in a loose state for subsequent extraction, put the raw materials into an extraction kettle, introduce liquid CO2, adjust the pressure and temperature to a suitable range, make CO2 reach a supercritical state, continue extraction for several hours, reduce the pressure and temperature through a separation kettle, separate the fish oil and CO2, and collect high-purity Omega-3 fish oil;

[0029] ② Activation treatment of biotin: Mix high-purity biotin raw materials with a specific buffer solution and continuously stir in a constant temperature water bath to form a uniform colloidal solution. By controlling the reaction conditions, the biotin molecules are fully dispersed to enhance their biological activity. The colloidal solution is sent to the spray drying equipment, and the inlet and outlet temperatures are adjusted to quickly dry the solution into nano-scale particles. The final product is a loose powder, ensuring that the particle size is small and the water content is low;

[0030] ③Synthesis of zinc chelate: Dissolve zinc gluconate and lysine in deionized water in proportion, heat in a water bath and stir continuously to promote the chelation reaction, and judge the degree of reaction completion by observing the transparency of the solution. Centrifuge the reaction solution to remove unreacted impurities, collect the supernatant and freeze-dry it to obtain a white powdery zinc chelate;

[0031] ④ Preparation of vitamin B complex: Weigh multiple vitamin B ingredients in proportion, mix them evenly with anti-caking agents to ensure no caking, use a three-dimensional mixer to fully stir to make the ingredients evenly distributed, send the mixed powder into the fluidized bed equipment, spray the adhesive solution, and form fine particles in the flowing state. After granulation is completed, use light-proof sealed packaging to prevent the vitamins from oxidizing and becoming ineffective.

[0032] Furthermore, the hair nutrient includes fish oil extract, biotin, zinc chelate and vitamin B complex, and their mass ratios are as follows: fish oil extract 15-20%; biotin 8-12%; zinc chelate 5-8%; vitamin B complex 10-15%. The fish oil extract can promote blood circulation in hair follicles, enhance hair luster and flexibility, and improve skin health by regulating sebum secretion. Biotin directly participates in keratin synthesis, accelerates the hair growth cycle, and alleviates hair loss problems. The vitamin B complex regulates the metabolism of hair follicle cells, promotes melanin production, and delays hair fading. Fish oil, biotin and zinc chelate directly act on hair growth and structural strengthening.

[0033] Furthermore, the synergistic components include methionine, cystine, green tea polyphenols and vitamin E, and their mass ratios are as follows: methionine 10-15%; cystine 5-8%; green tea polyphenols 3-5%; vitamin E 3-5%. Methionine provides sulfur elements to participate in keratin cross-linking and enhances hair strength. Cystine directly constitutes the hair keratin skeleton and improves the tensile strength of hair. Green tea polyphenols scavenge free radicals and reduce the damage of ultraviolet rays and oxidative stress to hair follicles. Vitamin E protects the integrity of cell membranes and synergistically with fish oil delays oxidative rancidity. Methionine and cystine strengthen keratin, and green tea polyphenols and vitamin E resist oxidative damage.

[0034] Furthermore, the functional excipients include maltodextrin, silicon dioxide and pregelatinized starch, and their mass ratios are as follows: maltodextrin 6-10%; silicon dioxide 2-4%; pregelatinized starch 2-5%. Maltodextrin improves the fluidity of additives and entraps sensitive components. Silicon dioxide adsorbs moisture, prevents particle adhesion, and ensures uniform mixing. Pregelatinized starch enhances particle formability and improves the tableting or granulation efficiency of products. Maltodextrin and pregelatinized starch optimize physical properties, and silicon dioxide ensures storage stability.

[0035] Furthermore, the zinc chelate is a stable complex formed by chemically combining zinc ions with organic ligands (such as amino acids). The zinc chelate is chelated from zinc gluconate and lysine in a molar ratio of 1:2 to form a zinc-lysine chelate, which directly participates in the synthesis of pet hair keratin, enhances hair strength and luster. The zinc chelate, as a cofactor of keratinase, strengthens the structural stability of hair and reduces breakage. Zinc deficiency may lead to loss of appetite, and also affect growth and development, causing slow hair growth. Therefore, zinc element needs to be supplemented to promote hair growth. The zinc chelate can improve the stability and bioavailability of zinc, thereby improving the absorption and utilization of zinc, and further improving the hair growth rate and hair quality.

[0036] Further, during the preparation process of the vitamin B complex, 0.5 - 1% of the total amount of microcrystalline cellulose is added as an anti-caking agent, and it is stored in light-proof aluminum foil packaging. The vitamin B complex is very sensitive to ultraviolet light and needs to be stored in the dark to prevent ingredient loss caused by direct sunlight. Microcrystalline cellulose is a white or off-white powder, odorless and tasteless, with a particle size usually between dozens of micrometers and hundreds of micrometers. It has good fluidity and compressibility. It is insoluble in water, dilute acids, organic solvents and oils, but can be hydrolyzed in concentrated acids under certain conditions. Microcrystalline cellulose has a certain hygroscopicity, but can maintain good stability in different humidity environments, thus ensuring the uniformity and fluidity of the product.
