Description

Technical Field

[0001] The invention belongs to the technical field of pet food processing, and in particular relates to adult cat food with the function of beautifying fur and a preparation method thereof. Background Art

[0002] In recent years, with the increasing demand for pet health, pet foods with specific functionalities have become a hot topic in the market. For adult cats, cat food products tend to reduce fecal odor, beautify fur and skin, maintain ideal body shape, and promote intestinal hair excretion. A cat's skin and coat health is closely related to its nutrient intake, especially a balanced intake of omega-3 and omega-6 fatty acids, which can effectively improve dry hair, increased dandruff, and skin inflammation. However, traditional cat foods for beautifying fur often rely on single ingredients such as fish oil and flaxseed, which can suffer from drawbacks such as poor oxidative stability, limited palatability, or an unsatisfactory fatty acid ratio. Summary of the Invention

[0003] To address the aforementioned problems of the prior art, the present invention provides an adult cat food with a coat-beautifying effect and a method for preparing the same; the aim is to improve the quality of a cat's coat, reduce hair loss, and enhance skin health. To achieve the aforementioned objectives, the present invention provides the following technical solutions: In a first aspect, the present invention provides an adult cat food with a coat-beautifying effect, wherein the components thereof include, by weight: 40-70 parts of meat, 5-20 parts of animal offal, 2-6 parts of chicken fat, 0.5-4 parts of fish oil, 0.2-3 parts of krill oil, 2-10 parts of fruit and vegetable powder, 2-10 parts of sweet potato granules, 3-10 parts of egg yolk powder, 1-5 parts of krill meal, 0.5-4 parts of seaweed powder, 0.1-0.5 parts of yucca powder, 0.1-0.5 parts of vitamin premix, 0.1-0.4 parts of mineral premix, and 0.2-2 parts of additives.

[0004] Krill meal is rich in phospholipid-based omega-3s, which have significantly higher bioavailability than triglyceride-based fish oil. It also naturally contains astaxanthin, which acts as a synergistic antioxidant and slows lipid peroxidation. Seaweed powder is a highly effective source of plant-based DHA. When combined with krill meal, it optimizes the fatty acid profile while providing polysaccharides to enhance skin barrier function. This scientific combination not only enhances the stability and absorption of key nutrients but also overcomes the limitations of a single ingredient, providing a more effective solution for enhancing the coat-beautifying properties of cat food.

[0005] In some other embodiments of the present invention, the components include, by weight: 50-70 parts of meat, 5-10 parts of animal offal, 3-5 parts of chicken oil, 1-3 parts of fish oil, 0.5-1 part of krill oil, 2-10 parts of fruit and vegetable powder, 2-8 parts of sweet potato granules, 3-5 parts of egg yolk powder, 2-4 parts of krill meal, 1-3 parts of seaweed powder, 0.1-0.5 parts of yucca powder, 0.1-0.5 parts of vitamin premix, 0.1-0.4 parts of mineral premix, and 0.5-2 parts of additives.

[0006] In some other embodiments of the present invention, the components include, by weight: 45-65 parts of meat, 8-20 parts of animal offal, 2-5 parts of chicken oil, 0.5-3 parts of fish oil, 0.5-2 parts of krill oil, 2-8 parts of fruit and vegetable powder, 2-8 parts of sweet potato granules, 3-10 parts of egg yolk powder, 1-3 parts of krill meal, 0.5-2 parts of seaweed powder, 0.1-0.5 parts of yucca powder, 0.1-0.5 parts of vitamin premix, 0.1-0.4 parts of mineral premix, and 0.2-1.5 parts of additives.

[0007] The meat is one or two of chicken, duck, and salmon; The animal offal is one or more of chicken heart, chicken liver, duck heart, and duck liver; The fruit and vegetable powder is one or more of carrot powder, pumpkin powder, blueberry powder, cranberry powder, and spinach powder; The additives are taurine, choline chloride, fructooligosaccharide, and mannooligosaccharide; The vitamin premix includes vitamin A, vitamin D3, vitamin B1, vitamin B6, vitamin B 12 , calcium D-pantothenate, vitamin B2, D-biotin, niacin, dl-α-tocopheryl acetate, L-ascorbic acid or two or more of folic acid; The mineral premix comprises two or more components of methionine iron complex, methionine copper complex, methionine zinc complex, methionine manganese complex or yeast selenium.

[0008] Carrot powder is rich in beta-carotene, which can be converted into vitamin A in the animal body. It has the function of regulating sebaceous gland secretion and improving hair dryness. It is also rich in carotenoids, vitamin C and other vitamins, has antioxidant effects, can reduce free radical damage, and delay hair aging; the plant sterols in pumpkin powder can balance skin oil secretion and reduce the problem of "oily hair". The dietary fiber in pumpkin can regulate the pet's gastrointestinal tract, improve digestion and absorption, and reduce abnormal hair loss caused by indigestion; the main active ingredients in cranberry powder and blueberry powder are proanthocyanidins and polyphenols, which can reduce skin inflammation, inhibit bacterial attachment, and reduce skin redness and swelling caused by allergies; spinach powder contains chlorophyll, which can remove toxins from the body and reduce problems such as dry and dull hair caused by excessive liver burden. At the same time, spinach powder is rich in iron. Iron is a key component for hemoglobin synthesis. Adequate iron can promote blood circulation and enhance the nutrient supply to hair follicles, making hair more shiny and resilient.

[0009] Taurine is an essential amino acid for cats. Its core function is to support heart and brain health. Its deficiency can lead to dilated cardiomyopathy or retinal degeneration. In addition, taurine can promote bile acid synthesis and promote the digestion and absorption of fat; choline chloride, as a precursor of acetylcholine, can synthesize neurotransmitters, support brain memory, maintain cell membrane integrity, and promote skin and hair health; fructooligosaccharides and mannan oligosaccharides have prebiotic effects, which can improve the balance of intestinal flora. They also have immunomodulatory effects, stimulate intestinal immune cells, and enhance the body's immune capacity. The synergistic use of the two can also relieve cats' soft stools.

[0010] In a second aspect, the present invention provides a method for preparing the cat food with hair beautifying effect as described in the first aspect, comprising the following steps: (1) performing a first mixing process on meat, animal offal, fruit and vegetable powder, sweet potato granules, egg yolk powder, yucca powder, vitamin premix, mineral premix, and additives to obtain a first mixture; (2) sequentially subjecting the first mixture to steam conditioning, extrusion granulation, cutting, and drying to obtain dried initial granules; (3) Evenly mixing chicken oil and fish oil in a certain proportion to obtain a first oil spraying material, and evenly spraying the first oil spraying material onto the initial particles under vacuum conditions to obtain first sprayed particles; (4) seaweed powder, krill powder and krill oil are mixed evenly in proportion to obtain a second spraying material, and the second spraying material is evenly sprayed onto the first spraying particles under vacuum conditions to obtain secondary spraying particles, which are cooled and solidified to obtain the cat food.

[0011] In some other embodiments of the present invention, in step (1), the mixing time is 5-10 minutes, and the mixing temperature is 40-50°C.

[0012] In some other embodiments of the present invention, in step (2), the steam pressure of the steam conditioning is 0.1-0.4 MPa, the steam temperature is 80-100° C., and the conditioning time is 60-120 seconds.

[0013] In some other embodiments of the present invention, in step (2), the extrusion granulation is carried out in an extrusion puffing machine, and the puffing parameters are: screw speed 250-350 rpm, puffing temperature 120-150°C, time 8-12 seconds, and pressure 0.8-1.2 MPa.

[0014] In some other embodiments of the present invention, in step (2), the drying temperature is 80-90° C. and the drying time is 20-30 minutes.

[0015] In some other embodiments of the present invention, in step (3), the first oil spraying material is vacuum sprayed, the vacuum pressure is 20-50 kPa, and the spraying temperature is controlled at 50-70°C; moderate vacuum pressure can help the oil penetrate the surface of the particles and avoid excessive adsorption leading to particle adhesion.

[0016] In some other embodiments of the present invention, in step (4), the second spray material is vacuum sprayed with a vacuum pressure of 40-60 kPa, and the spraying temperature is controlled in the range of 25-45°C. Lower vacuum degree and spraying temperature can reduce the loss of heat-sensitive components in seaweed powder and krill meal.

[0017] The moisture content of the final cat food is less than 10wt%.

[0018] In a third aspect, the present invention provides use of the adult cat food with hair beautifying effect described in the first aspect in preparing pet food.

[0019] All ingredients in this invention are derived from natural substances with a wide range of sources and are nutritious. The specific formula of this invention, particularly the specific ratio of krill meal to seaweed powder, can achieve a synergistic effect, significantly improving hair beautification through nutritional complementarity and functional enhancement. It can also specifically improve hair health issues, effectively reducing skin inflammation, promoting hair follicle vitality, and enhancing hair gloss. The specific ratio of krill meal to seaweed powder in this invention ranges from 1:1 to 2.5:1, more preferably from 2:1 to 2.5:1. Within this range, the omega-3 fatty acids in krill meal and the omega-6 fatty acids in seaweed powder form an ideal ratio, synergistically regulating cortical secretions and improving pet hair problems. Furthermore, the natural flavor compounds in krill meal can increase cats' food intake, and the umami components in seaweed powder can provide a complementary and enhancing effect. However, if the krill meal ratio is too high, the high phosphorus content in the krill meal may burden the cat's liver. If the seaweed powder ratio is too high, the iodine content in the seaweed powder may cause hyperthyroidism in pets. The synergistic mechanism between the two has the following effects: (1) Fatty acid complementation: Krill powder provides omega-3 fatty acids with high absorption efficiency, which inhibits skin inflammation and reduces hair loss; seaweed powder contains omega-6 fatty acids, which form an ideal ratio with omega-3, synergistically regulating cortical secretion and enhancing hair gloss; (2) Antioxidant synergy: Krill powder contains astaxanthin, which can effectively remove free radicals, slow down the damage of free radicals to hair follicles, and delay hair aging; the active substances in seaweed powder, such as seaweed polysaccharides, can enhance the antioxidant capacity of astaxanthin, prolong the duration of astaxanthin's action, and also reduce the fading of pet hair caused by ultraviolet rays or changes in the external environment; (3) Strengthening of minerals and trace elements: Seaweed powder is rich in trace elements such as iodine, selenium, zinc, and copper, which can participate in hair metabolism and accelerate hair growth. Iodine supports thyroid function, and thyroid hormone directly affects the hair growth cycle. Zinc and copper can promote the production of keratin; krill powder supplements selenium, calcium, phosphorus and other trace elements, which complement the trace elements of seaweed powder and provide more comprehensive nutrients.

[0020] (4) Synergistic effect of vitamins: Seaweed powder provides natural B vitamins and vitamin E, and krill powder is rich in fat-soluble vitamins (vitamin A, vitamin C, vitamin D). The combination of the two can cover fat-soluble vitamins and water-soluble vitamins, reducing hair thinning or breakage caused by vitamin deficiency.

[0021] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides an adult cat food with a hair-beautifying effect. The cat food uses krill powder and seaweed powder as the core functional combination of the cat food formula. Through precise ratio and process optimization, synergistic efficiency is achieved, and it has significant advantages in improving hair gloss, reducing abnormal hair loss and maintaining skin health. After pets are fed with the product of the present invention, the quality of their hair is improved to a certain extent, indicating that the product has a significant hair-beautifying effect and has outstanding technical innovation and market application value.

[0022] 2. The present invention provides a method for preparing adult cat food with coat-beautifying properties. This method utilizes a post-spraying process (coating technology) to dissolve seaweed powder and krill meal in krill oil and then atomize and spray the powder onto the pellet surface, forming a uniform, functional coating. This process effectively protects the active ingredients, preventing damage to heat-sensitive ingredients from high temperatures and high pressures, thereby preserving their biological activity. Furthermore, quantitative spraying ensures a uniform distribution of the active ingredients across the pellet surface, avoiding metering errors caused by uneven mixing. Krill oil, as a natural lipid carrier, effectively encapsulates the seaweed powder and krill meal, preventing oxidative degradation and extending the shelf life of the active ingredients. Low-temperature spraying minimizes the loss of heat-sensitive nutrients (such as astaxanthin and DHA), maximizing their biological activity. Furthermore, this process seamlessly integrates with existing puffed food production lines, making it suitable for industrialized production. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Example 1 A cat food for adult cats with the function of beautifying fur, comprising the following components in parts by mass: 46.5 parts chicken, 15 parts salmon, 6 parts chicken liver, 5 parts chicken fat, 2 parts fish oil, 0.5 parts krill oil, 8 parts sweet potato granules, 6 parts egg yolk powder, 1.8 parts carrot powder, 1.8 parts pumpkin powder, 1 part cranberry powder, 1 part blueberry powder, 2.5 parts krill meal, 1 part seaweed powder, 0.2 parts yucca powder, 0.3 parts vitamin premix, 0.2 parts mineral premix, 1 part additive; The additives are 0.3 parts of taurine, 0.3 parts of choline chloride, 0.2 parts of fructooligosaccharide, and 0.2 parts of mannooligosaccharide; The vitamin premix includes 0.03 parts of vitamin A, 0.03 parts of vitamin D3, 0.025 parts of vitamin B1, 0.025 parts of vitamin B6, and 0.03 parts of vitamin B 12 0.025 parts, D-calcium pantothenate 0.025 parts, folic acid 0.02 parts, D-biotin 0.025 parts, niacin 0.025 parts, dl-α-tocopheryl acetate 0.02 parts, L-ascorbic acid 0.025 parts, vitamin B2 0.025 parts; The mineral premix comprises 0.04 parts of methionine iron, 0.04 parts of methionine copper, 0.04 parts of methionine zinc, 0.04 parts of methionine manganese, and 0.04 parts of yeast selenium; A method for preparing adult cat food with hair-beautifying effect, such as Figure 1 As shown, the following steps are included: Step 1: Raw material pretreatment and mixing Thaw the chicken, salmon, and chicken liver naturally, clean them, remove the fat, and mince them. Pass the fruit and vegetable powder through an 80-mesh sieve. Add the processed meat and fruit and vegetable powders, egg yolk powder, vitamin premix, mineral premix, and additives according to the formula ratio into a double-blade mixer and mix them evenly to obtain a first mixture. Maintain the mixing temperature at 40-50°C, the mixing time at 5-10 minutes, and the speed at 20-30 rpm.

[0030] Step 2: Tempering and puffing Add the first mixture to the conditioner and steam condition it to promote starch gelatinization; control the steam pressure to 0.1-0.4 MPa, steam temperature to 80-100°C, and conditioning time to 60-120 seconds. Use a twin-screw extruder to extrude and granulate the tempered mixture, and set the expansion parameters to: screw speed to 250-350 rpm, The barrel temperature is 120-150°C, the die pressure is 0.8-1.2 MPa, and the residence time is 8-12 seconds to obtain expanded particles.

[0031] Step 3: Drying The expanded particles were dried using a multi-layer belt dryer with the drying parameters set at 80-90°C for 20-30 minutes to obtain initial particles.

[0032] Step 4: Vacuum spraying Mix chicken oil and fish oil in a ratio of 5:2 to create the first spraying material. Use a vacuum sprayer to vacuum-coat the dried initial pellets with grease to create the first sprayed pellets. Control the spraying parameters: vacuum pressure 20-50 kPa, oil temperature 25-40°C, spray volume 5-8% of the pellet weight, atomization pressure 0.3-0.5 MPa, and control the temperature of the first sprayed pellets at 50-70°C. This first spraying process aims to form a grease layer on the pellet surface, enhancing the flavor and palatability of the dry food while also forming a protective layer to prevent subsequent processing from damaging the active ingredients within.

[0033] Krill powder, seaweed powder and krill oil are mixed evenly according to the ratio of the formula to obtain the second spraying material, and a second spraying is performed. The spraying amount is controlled at 1-3% of the particle weight to obtain the second spraying particles.

[0034] Step 5: Cooling and packaging The secondary sprayed particles are transferred to a cooler for cooling to solidify the grease layer, and the moisture content and particle integrity of the final product are tested. The moisture content should be less than 10% and the breakage rate should be less than 3%.

Chicken oil, fish oil, and krill oil are mixed uniformly according to the formula ratio, and the dried initial granules are vacuum-sprayed with oil using a vacuum sprayer. The sprayed granules are transferred to a cooler for cooling, and finally packaged to obtain the product.

[0041] Performance testing: In order to verify the hair-beautifying effect of the cat food prepared by the present invention, the following experiment was conducted: During the experimental period, 30 healthy cats were randomly assigned to three groups of 10 cats each. Each group was fed the diets described in Comparative Example 1 (a commercially available adult cat food brand), Example 1, Example 2, and Example 3 for 45 consecutive days. Each cat was housed individually in a pet cat cage (1.6 m × 0.7 m × 0.7 m). Pre-experimentation with necessary immunizations and deworming was performed. Cat litter was changed daily, and the enclosures were cleaned and maintained.

[0042] On the 45th day of the experiment, the pet cats were subjected to fur sensory evaluation (hair brightness, hair smoothness, skin elasticity), coat length, coat fineness, coat color difference (L*, a*, b*), coat elastic recovery rate, coat elongation, hair loss weight, skin moisture, skin oil, skin pH and other indicators.

[0043] Coat sensory evaluation Three professionals conducted a randomized double-blind sensory evaluation of the animal coats, and the scoring criteria were as shown in Table 1 below.

[0045] The results of hair luminance, smoothness and skin elasticity are shown in Table 2, the results of hair length, hair fineness, hair brightness value and yellow-blue value are shown in Table 3, the results of hair elastic recovery rate, elongation and weight loss are shown in Table 4, and the results of skin moisture, oil content and skin pH are shown in Table 5.

[0046] Table 2

[0047] From the analysis of Table 2, it can be seen that in terms of hair luminescence brightness, the hair luminescence brightness scores of the embodiments are significantly higher than those of the comparative examples, among which the hair luminescence brightness score of Example 2 is the highest, indicating that the formula of Example 2 is the best in improving hair luminescence brightness; the hair luminescence brightness scores of Comparative Examples 1, 2, and 3 are relatively low, among which Comparative Example 1 has the lowest score. It can be seen that compared with cat food containing no seaweed powder and krill meal, or feeding cat food containing only krill meal or only seaweed meal, feeding cat food containing both seaweed powder and krill meal, the hair luminescence brightness of the cats is better than that of the cat food containing only krill meal or only seaweed meal. Cat food containing seaweed powder and krill meal has the best effect on improving the brightness of pet hair; in terms of hair smoothness, the hair smoothness scores of all examples are higher than those of the comparative examples, among which Example 3 has the highest hair smoothness score and is significantly higher than that of Comparative Examples 1, 2 and 3, indicating that compared with cat food without seaweed powder or krill meal, cat food containing seaweed powder and krill meal has the best effect on improving the smoothness of pet hair, and the two have a synergistic effect in improving the brightness and smoothness of pet hair.

[0048] Table 3

[0049] As can be seen from Table 3, after feeding the product of this example, there are significant differences in the physical and chemical indicators of pet hair, including the coat L* value and b* value. The L* value represents the hair brightness value, and the higher the value, the brighter the hair. The b* value represents the yellow-blue value, and its positive value represents the yellow value, indicating hair oxidation or pigmentation, etc., and a decrease in its value represents a decrease in hair oxidation. As can be seen from Table 3, the coat L* value of Example 2 is the highest, and the L* value of Comparative Example 1 is the lowest, indicating that the cat food formula of Example 2 is the best in terms of hair brightness. At the same time, it is consistent with the sensory indicator hair luminescence brightness result, indicating that the ratio of krill meal and seaweed powder in Example 2 is the most effective in improving hair brightness. In addition, the coat b* value of Example 2 is the lowest, significantly lower than that of Comparative Examples 1, 2, and 3, indicating that feeding the cat food of Example 2 can effectively reduce the oxidation and yellowing of pet hair. Comprehensive analysis of Table 2 shows that the ratio of krill meal and seaweed powder in Example 2 can effectively improve the glossiness of pet hair and reduce hair yellowing.

[0050] Table 4

[0051] As can be seen from Table 4, compared with the comparative example, the elastic recovery rate of the coat of all the embodiments is significantly increased, and the weight of hair loss is significantly reduced. Among them, the elastic recovery rate of Example 1 is the highest, and the weight of hair loss is the smallest. The higher the elastic recovery rate of the coat, the less damaged the hair is and the better the structural integrity is. Compared with the comparative example, although the coat elongation of the embodiments does not show significant difference, it tends to increase. It can be seen that after feeding the product of this embodiment, the elasticity of the cat's hair can be improved, the risk of hair breakage is reduced, and the hair loss phenomenon of the cat can be improved. Among them, the addition effect of seaweed powder and krill powder according to the ratio of Example 1 is the best.

[0052] Table 5

[0053] As shown in Table 5, compared with the comparative example, Examples 1, 2, and 3 all significantly increased skin moisture, with Example 3 having the highest moisture content. Skin oil content and hair pH values remained within healthy ranges, indicating that none of the products disrupted the skin's microecological balance. This indicates that feeding the product of the present invention can maintain the skin's water and oil balance, keeping the skin moisturized and protecting it from damage from the external environment.

[0054] In addition, in order to evaluate the stability and shelf life of the products using the inventive process, high temperature and high humidity accelerated tests were performed on Example 1 and Comparative Example 4: The test temperature was set at 40°C ± 2°C and the test humidity was set at 75% ± 5% RH. Example 1 and Comparative Example 4 were placed at this temperature and humidity for 30 days to observe the stability of the two products. The physical and chemical indicators (peroxide value, acid value) and nutritional indicator retention rate (astaxanthin, vitamin E) of Example 1 and Comparative Example 4 were measured on the 1st, 15th, and 30th days of the test. The test results are shown in Table 6: Table 6

[0055] It can be seen from the analysis of Table 6 that after 30 days of accelerated testing, the astaxanthin retention rate of Example 1 was 87%, which was 39.2% higher than that of Comparative Example 4; the vitamin E retention rate of Example 1 on the 30th day was 85.4%, while that of Comparative Example 4 was only 60.1%, which was 29.6% lower than that of Example 1, indicating that the post-spraying process of the effective ingredients can effectively reduce the loss of heat-sensitive components; the Omega-3 content of Example 1 decreased from 0.24% to 0.19% after 30 days of accelerated testing, a loss of 20.8%, while the Omega-3 of Comparative Example 4 decreased from 0.24% to 0.12%, a loss of 50%, indicating that compared with the traditional puffing process, the process of the present invention can effectively protect the hair-beautifying effective ingredients and extend their shelf life.

[0056] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
