Description

Technical Field

[0001] The invention relates to the technical field of pet food, and in particular to cat food capable of improving cat tear marks and beautifying cat fur, and a preparation method thereof. Background Art

[0002] In recent years, with the rapid development of the pet economy, cats' health and nutritional needs have received increasing attention. Tear stains and hair problems are two common health issues that plague pet owners, seriously affecting their cats' quality of life and appearance. Tear stains are primarily caused by abnormal tear secretion or blocked tear ducts. They are common in cats with eye diseases (such as conjunctivitis and keratitis) or improper diets (such as high salt and high fat). Long-term presence of these problems can lead to eye infections. Meanwhile, problems such as rough, dull, or abnormal hair loss are often associated with unbalanced nutrition, insufficient intake of essential fatty acids, or poor skin health.

[0003] Currently, most cat foods on the market focus on basic nutrition. While some products claim to improve tear stains or beautify fur, their actual effectiveness is limited. Furthermore, most products are in the form of nutritional supplements or functional additives, which cannot meet daily feeding needs. Therefore, there is an urgent need to develop a complete cat food that can both improve tear stains and promote fur health. By scientifically formulating natural active ingredients, this food could regulate a cat's tear secretion and skin and fur health from the source of the diet, achieving long-term and stable improvements.

[0004] In response to the above-mentioned market demands and technical gaps, the present invention provides a cat food that can improve cat tear marks and has a hair-beautifying effect, and a preparation method thereof. This cat food synergistically regulates cat tear secretion and skin barrier function by optimizing protein sources, adding specific plant extracts (such as chrysanthemum, cassia seed, and other heat-clearing and eye-improving ingredients), and supplementing Omega-3 / 6 fatty acids and trace elements such as zinc. At the same time, a low-temperature baking process is used to retain nutrients and avoid high temperatures from destroying the activity of functional substances. This product is used as a daily staple food, not a short-term additive, and can safely and long-term improve cat tear marks and hair problems, and has significant market application value.

[0005] Patent CN 117122627A discloses a Chinese medicine composition and its use in preparing a pet nutritional supplement, comprising a Chinese medicine composition, corn starch, Cynanchum chinense extract, glutamine, mannitol, magnesium stearate, and carboxymethyl cellulose;

[0006] The additives include at least one of taurine, vitamin A, vitamin B1, vitamin B2, vitamin B6, vitamin B12, vitamin C, vitamin D3, vitamin E, vitamin K1, vitamin K2, folic acid, niacin, D-pantothenate calcium, and D-biotin; the composition containing traditional Chinese medicine includes marigold, chicory, astragalus, angelica, brewer's yeast powder, and defatted chicken liver powder; the additive is used as a food supplement and is claimed to improve the problems of dry, discolored, frizzy, and hair loss hair, and has a good whitening and skin care effect, while being able to enhance physical fitness, nourish the stomach and intestines, protect eyesight, and promote development.

[0007] Although the Chinese medicine composition and nutritional supplement disclosed in this patent have certain functional properties (such as possible anti-inflammatory, antioxidant or metabolic regulation effects), they still have the following problems and limitations when used as cat food additives or complementary foods:

[0008] As a supplement or additive, it's difficult to achieve long-term, stable improvement. Since it's not a staple food, compliance is low: This product is a nutritional supplement (supplement / additive) and requires additional feeding. However, cats may struggle to maintain consistent use due to palatability and feeding habits, resulting in inconsistent results. Pet owners may not be able to precisely control intake, and excessive or insufficient intake can compromise results and even lead to nutritional imbalances. This supplement contains multiple vitamins (such as A, D, and K). If used with the main food, it can lead to accumulation and toxicity of fat-soluble vitamins (such as A and D). Taurine is an essential nutrient for cats, but if sufficient amounts are already present in the main food, supplementing it offers no additional benefit. The traditional Chinese medicine ingredient, thistle, may affect blood clotting, posing a potential risk; long-term use requires caution. Tear stain improvement requires tear gland regulation or anti-inflammatory measures (such as omega-3s and zinc), while maintaining a healthy coat requires high-quality protein and essential fatty acids (such as fish oil and egg yolk powder). The Chinese herbal composition in this patent (such as astragalus and angelica) is more inclined towards immune regulation rather than directly targeting eye health or hair health.

[0009] Drug extracts may affect palatability. For example, Cynanchum indica and Cyperus rotundus have a distinctive odor that may cause cats to refuse to eat. Excipients such as magnesium stearate and carboxymethyl cellulose are not necessary: these ingredients are mainly used for molding (such as tablets), but cat food additives should be kept as simple as possible to avoid non-nutritional additives.

[0010] Pet owners are more inclined to choose functional staple foods (such as hypoallergenic foods and hair-beautifying foods) rather than adding supplements. This has led to the development of complete nutritional cat foods that can more stably and safely improve tear stains and hair-beautifying problems, and thus have a wider market demand. Summary of the Invention

[0011] In view of the defects and shortcomings of existing cat food, the present invention proposes a cat food that can improve cat tear marks and has a beautifying effect on cat fur and a preparation method thereof. The cat food is used for daily feeding of cats, effectively improving the problem of cat tear marks and having a beautifying effect on cat fur.

[0013] A cat food for improving tear stains and beautifying cat fur, comprising the following ingredients in parts by weight: 30-70 parts of poultry meat, 5-20 parts of fish meat, 2-22 parts of poultry offal, 2-5 parts of vegetables, 0.5-5 parts of fish oil, 1.6-4.5 parts of plant extracts, and 1-3 parts of egg yolk powder; supplementary ingredients include 0.1-0.5 parts of taurine, 0.5-2 parts of lecithin, 0.1-0.5 parts of yucca extract, 0.05-0.1 parts of choline chloride, 0.1-0.2 parts of sodium chloride, 0.1-0.3 parts of fructooligosaccharides, and 0.2-2 parts of additive premix feed;

[0014] The plant extracts are cranberry, marigold and cassia seed extracts; wherein the cranberry extract is 0.5-2 parts, the marigold extract is 0.5-1 parts, and the cassia seed extract is 0.5-1 parts.

[0015] Preferably, the plant extract is a product obtained by drying the plant after solvent extraction; when the plant is cranberry or marigold, the solvent is ethanol, and when the plant is cassia seed, the solvent is water.

[0016] Preferably, the plant extract extraction process is as follows: a solid-liquid ratio of 1g:2-10ml, 1-3 extractions; the extracts are combined and dried to obtain the plant extract; the drying temperature is 60-90°C; when the extract is Cassia seed, each extraction is boiled for 30-50 minutes; when the extract is cranberry or marigold, the ethanol concentration in the extraction process is 50-70wt%, and each ultrasonic extraction is performed for 30-50 minutes. The preparation process of yucca extract is the same as that of cranberry or marigold.

[0017] Preferably, the poultry meat is one or more of chicken breast, chicken thigh and duck breast; the fish meat is one or more of salmon, tuna, bonito and Spanish mackerel.

[0018] Preferably, the poultry offal is one or more of chicken heart, chicken liver and chicken gizzard; and the vegetables are one or more of carrot, pumpkin, broccoli and spinach.

[0019] Preferably, the additive premix feed is vitamin A, vitamin B1, vitamin B2, vitamin B6, vitamin B12, vitamin D3, niacin, D-biotin, folic acid, glycine iron complex, glycine copper complex, methionine zinc complex, methionine manganese complex and calcium pantothenate in a mass ratio of 0.3-0.6:0.5-2:0.1-0.3:0.1-0.3:0.1-0.3:0.3-0.7:0.1-0.3:0.1-0.3:0.1-0.3:1-3:1-3:1-3:1-3:1-3.

[0020] Preferably, the method for preparing the cat food that can improve cat tear marks and has the effect of beautifying cat fur comprises the following steps:

[0021] (1) Steam poultry, fish, and poultry offal, and clean and chop vegetables;

[0022] (2) chopping the poultry, fish, and poultry offal steamed in step (1) into a meat paste, and uniformly mixing the vegetables processed in step (1) and the remaining raw materials with the meat paste to obtain a mixture;

[0023] (3) The mixture of step (2) is filled and sealed, sterilized at high temperature, and cooled to obtain a cat food product.

[0024] Preferably, the process for steaming the poultry meat, fish meat and poultry offal in step (1) is steaming at normal pressure for 30-60 minutes.

[0025] Preferably, the temperature of the high temperature sterilization in step (3) is 110-130° C. and the time is 40-60 min.

[0026] Preferably, the mixture is placed at room temperature for 5-9 days after warming.

[0027] Cranberry Extract: Contains polyphenols such as anthocyanins and flavonoids, which have powerful antioxidant effects and can reduce tear secretion; taurine is an important component of the retina and can promote eye health. It can also promote skin and hair health, making hair smoother and more beautiful.

[0028] Cassia seed extract contains a variety of active ingredients, including emodin, chrysophanol, physophanol methyl ether, cassia, cassia bark and its glycosides, as well as flavonoids, vitamin A, and carotene. It helps improve ocular microcirculation, clears heat and improves eyesight, reduces inflammation and inhibits bacteria, and has a protective effect on the liver. It also promotes intestinal motility, effectively prevents constipation, and helps enhance immunity. It also helps prevent cardiovascular diseases such as hypertension and atherosclerosis. Cranberry (proanthocyanidins) and cassia seed (chrysophanol) work synergistically to effectively inhibit tear gland secretion.

[0029] Marigold extract: Its main active ingredient is lutein, a natural antioxidant that can increase the density of retinal macular pigment, protect the macula, and inhibit oxidative damage to tissues such as the lens and macula. In addition, lutein is a type of carotene and has the function of inhibiting and scavenging free radical activity.

[0030] Yucca extract is rich in yucca saponins, yucca polysaccharides, yucca polyphenols, resveratrol, antioxidants such as vitamin C, vitamin E, beta-carotene and other effective ingredients. These ingredients can work synergistically and have significant effects in deodorizing and reducing ammonia, promoting intestinal health, enhancing immunity, anti-inflammatory and cleansing, and reducing the risk of heart disease.

[0031] Fish oil is rich in Omega-3 fatty acids, which can enhance the skin barrier function, lock in moisture, prevent dryness, and make hair smoother and softer. At the same time, the EPA in fish oil can reduce skin inflammation, relieve itching and hair loss.

[0032] Taurine is an important component of the retina and can promote eye health. It can also promote skin and hair health, making hair smoother and shinier.

[0033] Choline chloride regulates fat metabolism and conversion, effectively preventing and treating fat deposition and tissue degeneration in the liver. It can be used to treat fatty liver disease and cirrhosis. As a methyl donor, choline chloride promotes the reformation of amino acids and improves their utilization. Choline chloride is a key nutrient for the synthesis of the neurotransmitter acetylcholine, promoting normal nerve function. Choline chloride also activates α7 nicotinic receptors, exhibiting analgesic and anti-inflammatory properties, and has a certain impact on liver disease, atherosclerosis, and neurological diseases.

[0034] Fructooligosaccharides (FOS) promote the proliferation of bifidobacteria and help regulate the balance of intestinal flora, thereby improving a cat's digestive health. Furthermore, FOS is rapidly fermented by coliform bacteria in the colon, helping to increase the number of beneficial bacteria and inhibit the growth of harmful ones. When combined with yucca extract, FOS can more precisely regulate intestinal flora, promoting intestinal health and reducing fecal odor.

[0035] Beneficial effects of the present invention:

[0036] 1. The cat food provided by the present invention can improve cats' tear marks and has the effect of beautifying their fur. The various raw materials and components work synergistically to improve the cats' tear marks while also beautifying their fur. The meats selected are fish, poultry, and offal, which are rich in high-quality protein, multiple vitamins, and minerals, and are more in line with cats' tastes. Adequate and high-quality protein can promote hair growth, making the hair thicker and more lustrous. It is also rich in dietary fiber, which is beneficial to the cat's gastrointestinal health.

[0170] Test Case

[0171] Fifty Garfield cats with tear marks were selected (Garfield cats generally have tear marks) and randomly divided into 10 groups, with 5 cats in each group.

[0172] Feeding and management of test cats: Test cats are raised in indoor cages, and each cat occupies an area of about 2m 2The room was kept well ventilated. During the experiment, the test cats were allowed to drink water freely. Each group was fed the cat food of Examples 1-5 and Comparative Examples 1-5 (10 g / kg / day) in a fixed amount every day. The Schirmer test was performed on the 0th day, the 7th day, the 14th day, the 21st day, the 28th day, and the 35th day, and the tear marks were recorded. The test results are shown in Table 1. The smoothness of the cat's fur was tested using the method in Table 1 of TSDPIA06-2022. The test results are shown in Table 2:

[0173] Table 1

[0174]

[0175] Table 2

[0176]

[0177] It can be seen from Table 1 and Table 2 that the cat food of the present invention can effectively remove tear marks and has the effect of beautifying the cat's fur.

[0178] By comparing Example 1 with Comparative Example 1, it can be seen that the cat food of the present invention contains key ingredients for removing tear marks. Adding it to a pet nutritional supplement can significantly improve the effect of removing tear marks, and the cranberry, marigold and cassia seed extracts in the traditional Chinese medicine composition have a significant synergistic effect in removing tear marks.

[0179] Comparison of the results of Example 2 and Comparative Example 2 shows that the addition of excipients improves the health of cats, thereby having a beautifying effect on their fur. The lecithin, fructooligosaccharides (prebiotics) and probiotics in the excipients work together to reduce the absorption of food allergens, reduce tear secretion caused by allergies, alleviate skin and periocular inflammation, and relieve irritation-type tear marks. Yucca extract improves the intestinal environment and may indirectly reduce allergic reactions. Choline chloride promotes sebum metabolism, reduces dry skin and dandruff. Taurine is an essential amino acid for cats, maintaining the function of the retina, myocardium and immune system. It can synergistically improve the health of cats, thereby improving tear marks and having a beautifying effect on their fur.

[0180] Comparison of the results of Example 3 and Comparative Example 3 shows that poultry offal has a special aroma that can mask the special taste of Chinese medicinal ingredients, increase palatability, and increase the willingness to eat, while deep-sea fish meat has Omega-3 fatty acids (EPA / DHA) and anti-inflammatory ingredients, which help regulate the health of the skin and hair follicles and reduce dandruff or itching caused by inflammation. Omega-3 can relieve inflammation of the skin or lacrimal glands around the eyes and reduce tear marks caused by excessive tear secretion. Some tear marks are caused by food allergies, and the hypoallergenic protein of deep-sea fish may reduce the risk of allergies. Improve hair gloss, Omega-3 and Omega-6 fatty acids can strengthen the skin barrier, reduce dryness and dandruff, and make hair soft and shiny. It has high-quality protein, provides essential amino acids, supports hair keratin synthesis, and promotes hair growth and toughness. It is rich in multiple vitamins A, D, and B12. Vitamin A maintains the health of the eyes and skin mucosa and reduces the increase in tears caused by infection or irritation; Vitamin D promotes calcium absorption; and B12 supports metabolism. Contains multiple minerals (iodine, selenium, and zinc). Zinc and selenium contribute to antioxidant activity and reduce skin inflammation; iodine supports thyroid function (indirectly impacting hair quality). High-quality protein provides nutrients necessary for hair growth, while zinc and B vitamins reduce hair brittleness and breakage. Anti-inflammatory ingredients alleviate skin problems caused by eczema, parasites, or allergies, indirectly improving hair condition. Comparative Example 3, where the main ingredient is solely poultry, is nutritionally unbalanced, resulting in a rough, matted cat's coat.

[0181] Comparing the results of Examples 4-5 with Comparative Examples 4-5 demonstrates that the present invention further enhances the tear stain removal efficacy of marigold extract by combining cranberry and cassia seed, improving tear stain removal effectiveness. Cranberry contains polyphenols such as anthocyanins and flavonoids, which have potent antioxidant properties and can reduce tear secretion. Cassia seed extract, whose main active ingredient is free anthraquinones, has heat-clearing, eye-improving, anti-inflammatory, and antibacterial effects in animals. The combined use of these components creates a synergistic effect, not only improving tear stains on cats but also enhancing fur beautification.

[0182] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
