Description

Technical Field

[0001] The invention relates to the technical field of animal feed, and in particular to a composition with the function of beautifying pet hair, pet dry food and a preparation method thereof. Background Art

[0002] In today's society, pets have become an indispensable member of many families. With the steady improvement of residents' quality of life, people have invested more and more energy and resources in their pets. Among them, the appearance of pets, especially the hair condition, has attracted much attention from pet owners. In life, many pets suffer from severe hair loss and rough hair due to insufficient or unbalanced nutrition intake, which not only affects the appearance of pets, but also reflects the health status of pets to a certain extent.

[0003] The current pet dry food market continues to expand, and there are many types of products, but a pet food that can truly improve a pet's hair is very rare. In the field of pet health products, capsules and tablets are the dominant forms, but due to their poor taste and difficulty in swallowing, long-term regular feeding is difficult to achieve, and thus it is impossible to ensure that the hair-beautifying ingredients continue to act on the pet's body, and the hair-beautifying effect is greatly reduced. In the existing technology, most products only focus on one or two hair-beautifying ingredients, such as simply adding fish oil. But in fact, relying solely on the unsaturated fatty acids in fish oil to improve hair texture cannot meet the comprehensive nutrition of pet hair.

[0004] In addition, the current mainstream process uses surface spraying (such as direct spraying of fish oil) to enhance the hair of puffed dry food. This process has two inherent defects: (1) the oil sprayed on the surface of the dry food is prone to oil migration during storage, resulting in greasy surface, affecting the appearance and palatability of the product; (2) unsaturated fatty acids (such as EPA / DHA in fish oil) are in contact with air, and as the storage time increases, they accelerate oxidation and rancidity, reducing the nutrient absorption rate. Therefore, both the sensory and digestion absorption rates are affected.

[0005] It can be seen that the existing technology still needs to be improved and enhanced. Summary of the invention

[0006] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a composition having a pet hair beautifying effect, a pet dry food and a preparation method thereof, aiming to improve the hair beautifying function of pet health products or pet dry food.

[0028] The present invention provides a composition having the function of beautifying pet hair, a pet dry food and a preparation method thereof. In order to make the purpose, technical scheme and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] See also Figure 1 The present invention provides a first aspect of a composition having a pet hair beautifying effect, which comprises, by weight: 2 to 6 parts of safflower seed oil, 1 to 2 parts of fish oil, 0.5 to 4 parts of soybean oil, 0.5 to 2 parts of krill oil, and 0.02 to 0.05 parts of perilla seed extract.

[0030] Among the above components, safflower seed oil is rich in linoleic acid, which is an Omega-6 fatty acid. Taking cats as an example, from the skin level, linoleic acid is one of the basic substances that constitute the cell membrane of cat skin. It can maintain the stability of the skin cell structure, ensure the normal metabolism and renewal of the skin, and then strengthen the skin barrier function, resist external stimuli, and avoid skin dryness, inflammation and other problems. Going deep into the hair level, linoleic acid participates in the lipid metabolism in the cat's body, and the converted arachidonic acid and other substances can provide nourishment for hair fibers, making them tougher and less prone to breakage and splitting. At the same time, these nourishing ingredients make the hair surface smoother, showing a shiny, soft and smooth state, reducing the phenomenon of hair tangling from the root, and helping dogs and cats have beautiful hair.

[0031] Soybean oil is a high-quality energy source that can provide sufficient energy for pets' daily activities and meet the energy needs of active pets. Secondly, the aroma of soybean oil can improve the palatability of dry food, attract pets to eat, and ensure that they take in enough nutrition. In addition, soybean oil also contains a large amount of linoleic acid. In addition, soybean oil helps pet cats and dogs absorb fat-soluble vitamins, such as vitamin E, which are important for the growth and development, anti-oxidation and other aspects of cats and dogs, and are also indirectly beneficial to hair health.

[0032] Fish oil is rich in Omega-3 fatty acids, especially DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid). These fatty acids can improve the health of cats' skin, enhance the skin's barrier function, reduce the occurrence of skin inflammation, and make cats' skin healthier. In terms of hair care, Omega-3 fatty acids can penetrate deep into the hair follicles, nourish the hair, reduce the roughness and brittleness of the hair, and make the cat's hair shinier and smoother. In addition, DHA also has a certain promoting effect on the development of cats' brains and vision. It helps to improve cats' cognitive abilities, making them more sensitive when they are active and learning new things. At the same time, it is also beneficial to maintain cats' good vision and enhance their ability to perceive the environment. This is not only about beautiful hair, but also has a positive effect on the overall health and vitality of cats.

[0033] Krill oil is also rich in Omega-3 fatty acids, especially EPA and DHA. In addition, krill oil also contains astaxanthin. Astaxanthin can resist the damage of free radicals to the pet's body, including damage to skin and hair cells, and help delay the aging process of skin and hair. At the same time, it can also enhance the immunity of pets, making pets healthier and more lively.

[0034] Perilla seed extract is rich in alpha-linolenic acid, an omega-3 fatty acid. Alpha-linolenic acid can improve the health of cats' skin, reduce skin inflammation, enhance the skin's barrier function, and reduce itching and hair loss caused by skin problems. In terms of hair care, alpha-linolenic acid can nourish hair follicles, making cats' hair thicker, shinier and more elastic, and helping to improve hair quality.

[0035] Moreover, perilla seed extract also has certain antioxidant properties, which can help cats' bodies remove free radicals and slow down the aging of cells. This is not only beneficial to skin and hair cells, but also can enhance the overall immunity of cats to a certain extent, make cats grow healthier, reduce the probability of disease, and keep cats' hair in good condition for a long time.

[0036] Preferably, the mass ratio of safflower oil, fish oil, soybean oil and krill oil is 4:2:2:1.

[0037] Preferably, the linoleic acid content of safflower seed oil is not less than 67.8% (mass fraction), the acid value (KOH) is not higher than 4 mg / g, the moisture and volatile matter are not higher than 0.5% (mass fraction), and the peroxide value is not higher than 7.5 mmol / kg;

[0038] The acid value (KOH) of soybean oil shall not exceed 2.5 mg / g, the moisture and volatile matter shall not exceed 0.5%, and the peroxide value shall not exceed 2.5 mmol / kg;

[0039] The total content of docosapentaenoic acid EPA and docosahexaenoic acid DHA in fish oil is not less than 20%, the acid value (KOH) is not higher than 1 mg / g, the moisture and volatile matter are not higher than 0.1%, the iodine value is not lower than 140g / 100g, the peroxide value is not higher than 6mmol / kg, and the content of unsaponifiable matter is not higher than 3%.

[0040] By means of the above definition, the effectiveness of the hair beautifying function of the composition can be ensured.

[0041] The second aspect of the present invention provides the use of the composition having the effect of beautifying pet hair in pet dry food, pet wet food or pet health products.

[0042] The third aspect of the present invention provides a pet dry food with the function of beautifying fur. The raw materials for preparing the pet dry food include, by mass percentage, 8% to 12% of the above-mentioned composition, and the rest are basic raw materials and additives.

[0043] Preferably, the raw materials for preparing the pet dry food include, by mass percentage: 87% to 91% of the basic raw materials, 0.5% to 3% of the additives, and 8% to 12% of the above-mentioned composition.

[0044] Preferably, the basic raw materials include: fresh chicken, chicken powder, chicken hydrolyzed powder, sweet potato powder, potato powder, frozen chicken liver, cellulose, egg yolk powder, chicken liver powder, yam, cranberry powder, pumpkin powder, psyllium, chicory inulin, and glucosamine hydrochloride.

[0045] Preferably, the additives include multiple types of vitamins, trace elements, taurine, oligofructose, galacto-oligosaccharides, and rosemary extract.

[0046] Preferably, a pet dry food with the function of beautifying fur comprises, by weight percentage, the following raw materials:

[0047] Basic raw materials: fresh chicken 20%-40%, chicken powder 12%-20%, chicken hydrolyzed powder 3%-20%, frozen chicken liver 2%-5%, chicken liver powder 2%-4%, sweet potato powder 8%-12%, potato powder 2%-10%, cellulose 2%-4%, egg yolk powder 1%-5%, yam 0.3%-3.5%, cranberry powder 0.2%-1.5%, pumpkin powder 0.2%-1.5%, psyllium 0.5%-1%, chicory inulin 0.5%-1%, glucosamine hydrochloride 0.02%-0.08%;

[0048] Additives: vitamins 0.1% to 0.3%, trace elements 0.1% to 0.3%, taurine 0.1% to 0.3%, oligosaccharides 0.1% to 0.3%, galacto-oligosaccharides 0.1% to 0.3%, rosemary extract 0.1% to 0.3%;

[0049] The composition having the effect of beautifying pet's hair is 8.5% to 9.5%.

[0050] A fourth aspect of the present invention provides a method for preparing dry pet food, which is used to prepare the above-mentioned dry pet food with a hair-beautifying effect, and comprises the following steps:

[0051] S01. Prepare safflower oil, fish oil, soybean oil, krill oil according to the formula, and then prepare an oil composition emulsion by an emulsification process;

[0052] By using an emulsification process to emulsify the oil, the oil is formed into tiny oil droplets that are evenly dispersed in the system, which greatly increases the contact area between the oil and the pet's digestive enzymes, making the nutrients in the oil, such as fatty acids, easier to absorb, thereby providing the necessary nutritional support for hair growth and repair, making the hair more shiny and tougher.

[0053] S02. The perilla seed extract is embedded by an embedding process to form microcapsules;

[0054] For the heat-sensitive substance Perilla seed extract, the embedding process can isolate the heat, moisture and oxygen invasion during the processing process, and achieve intestinal targeted release to ensure that the nutrients are efficiently absorbed in the pet's intestines;

[0055] S03. Fresh chicken, chicken meal, chicken hydrolyzed powder, sweet potato powder, potato powder, frozen chicken liver, cellulose, egg yolk powder, yam, cranberry powder, pumpkin powder, psyllium, chicory inulin, glucosamine hydrochloride, and additives are crushed and fully mixed to form base particles through a puffing process;

[0056] S04. Spraying the oil composition emulsion onto the base particles, and then mixing the microcapsules and chicken liver powder and spraying them onto the base particles to obtain the pet dry food with the effect of beautifying hair.

[0057] Preferably, the step S01 comprises: preparing safflower oil, fish oil, soybean oil and krill oil according to the formula, mixing them evenly, adding the emulsifier soybean lecithin while stirring; then adding the aqueous phase while stirring to complete the preliminary emulsification, homogenizing and obtaining the oil composition emulsion.

[0058] Specifically, safflower oil, fish oil, soybean oil, and krill oil are weighed according to the formula, and then added to a stirring container, and low-speed stirring (the speed is 50 to 100 rpm) is started, and preliminary mixing is performed, and stirring is continued for 5 minutes to ensure that the oil phase is evenly mixed; the emulsifier soybean lecithin is slowly added to the stirred oil phase (the mass ratio of the emulsifier to the oil phase is 1.5:100 to 3:100), and stirring is continued while adding to allow the emulsifier to be fully dispersed in the oil phase;

[0059] Add the aqueous phase, which can be deionized water or a specially formulated aqueous solution (the mass ratio of the aqueous phase to the oil phase is set to 1:1-2:1), and slowly add it in a thin stream into the oil emulsification system that is being stirred at high speed (speed of 2000-4000 rpm). The speed of water addition must be strictly controlled to prevent the system from demulsifying. After adding water, continue to stir at high speed to promote the formation and stability of the emulsion.

[0060] After the initial emulsification is completed, the homogenization stage begins, and the emulsion is transferred to a high-pressure homogenizer. The high pressure further refines the oil droplets in the emulsion and makes the particle size distribution more uniform. After three cycles of homogenization, the stability and fineness of the emulsion are greatly improved.

[0061] Preferably, step S02 comprises: weighing maltodextrin and gelatin in a mass ratio of 4:1, adding deionized water to prepare a mixed solution with a total mass concentration of 15%, and stirring at 45-55°C until completely dissolved; slowly adding perilla seed extract to the wall material solution in a mass ratio of wall material: core material = (5-10):1, stirring at 200-400 rpm for 5-15 minutes to form an oil-in-water emulsion; spraying the emulsion into a low-temperature cooling medium, and forming microcapsules through rapid solidification.

[0062] This method has a very fast cooling speed, which almost does not give the heat-sensitive perilla seed extract a chance to be heated, thus retaining its activity to the greatest extent, while also ensuring that the perilla seed extract is not affected by heat. Finally, screening equipment can be used to screen out microcapsule products with qualified particle sizes, and then stored in a cool and dry environment to ensure the effectiveness of the product.

[0063] The present invention is further described with reference to the following examples and comparative examples.

[0064] Example 1

[0071] After the initial emulsification is completed, the homogenization treatment stage is entered, and the emulsion is transferred to a high-pressure homogenizer and homogenized three times to obtain a grease composition emulsion;

[0072] S02. The perilla seed extract is embedded by an embedding process to form microcapsules;

[0073] S03. Fresh chicken, chicken meal, chicken hydrolyzed powder, sweet potato powder, potato powder, frozen chicken liver, cellulose, egg yolk powder, yam, cranberry powder, pumpkin powder, psyllium, chicory inulin, glucosamine hydrochloride, and additives are crushed and fully mixed to form base particles through a puffing process;

[0074] S04.

Test group 1 was fed with pet dry food according to Example 1, test group 2 was fed with pet dry food according to Example 2, test group 3 was fed with pet dry food according to Example 3, test group 4 was fed with pet dry food according to Example 4, test group 5 was fed with pet dry food according to Example 5, test group 6 was fed with pet dry food according to Comparative Example 1, test group 7 was fed with pet dry food according to Comparative Example 2, test group 8 was fed with pet dry food according to Comparative Example 3, test group 9 was fed with pet dry food according to Comparative Example 4, test group 10 was fed with pet dry food according to Comparative Example 5, test group 11 was fed with pet dry food according to Comparative Example 6, test group 12 was fed with pet dry food according to Comparative Example 7, and other conditions were kept consistent in each group. Three professionals were designated on the 0th day and the 25th day of the test to score the hair condition of each cat according to the scoring criteria and summarize the statistics.

[0125] Table 1 Pet cat hair scoring standards

[0126] Points Evaluation content 1 point The hair is very rough, dry and dull, with noticeable tangles and knots. 2 points The hair is relatively rough, less shiny, and has some slight tangles. 3 points The hair has a certain luster and no obvious tangles, but it is rough and split. 4 points The hair is shiny, tangle-free and smooth. 5 points The hair is very shiny, without any tangles, and extremely soft and smooth.

[0127] Depend on Figure 1 It can be seen that there is no significant difference in the hair score of each group of cats at 0d. Among them, the average score of Example 1 is 2.94, the average score of Example 2 is 2.89, the average score of Example 3 is 2.83, the average score of Example 4 is 3, the average score of Example 5 is 2.94, the average score of Comparative Example 1 is 2.94, the average score of Comparative Example 2 is 2.89, the average score of Comparative Example 3 is 2.78, the average score of Comparative Example 4 is 3.06, the average score of Comparative Example 5 is 3.11, the average score of Comparative Example 6 is 3.11, and the average score of Comparative Example 7 is 3.06;

[0128] After 25 days of feeding, the average score of Example 1 was 4.28, the average score of Example 2 was 4, the average score of Example 3 was 3.94, the average score of Example 4 was 4, the average score of Example 5 was 3.94, the average score of Comparative Example 1 was 3.33, the average score of Comparative Example 2 was 3.39, the average score of Comparative Example 3 was 3.5, the average score of Comparative Example 4 was 3.44, the average score of Comparative Example 5 was 3.44, the average score of Comparative Example 6 was 3.67, and the average score of Comparative Example 7 was 3.72;

[0129] Embodiment 1, embodiment 2, embodiment 3, embodiment 4, and embodiment 5 all have the effect of significantly improving the hair score, and are better than the hair scores of each comparative example. Among them, the effect of embodiment 1 is the best. It means that after feeding the pet dry food with compound oil and perilla seed extract, the hair of the pet cat has a better hair beautification effect than the other comparative example groups, and the brightness and smoothness of the hair are improved.

[0130] Compared with Example 1, Comparative Examples 1 to Comparative Examples 6 respectively reduced at least one of safflower seed oil, fish oil, soybean oil, krill oil and perilla seed extract. From the results, it can be seen that after reducing some components, the hair beautifying effects were reduced.

[0131] Compared with Example 1, the hair beautifying effect of Comparative Example 7 is not as good as that of Example 1. The reason is that the difference in preparation process leads to less actual digestion and absorption of the hair beautifying composition by cats, thus resulting in worse hair beautifying effect.

[0132] Test 2: Cat hair scanning electron microscope evaluation

[0133] In order to directly measure the effect of pet dry food on the hair quality of pet cats, this test example designed a 25-day feeding test to explore the specific effect of the composition with pet hair beautification effect of the present invention on the hair quality of cats.

[0134] 20 healthy adult ragdoll cats were selected and randomly divided into 2 test groups, each with 10 cats. Test group 1 was fed with the cat food of comparative example 1, and test group 2 was fed with the cat food of example 1, and other conditions of each group remained the same.

[0135] 2.1 Body weight, feed intake and feces scores

[0136] Each cat was weighed on an empty stomach on the 0th day and the 25th day of the experiment, and the cat's food intake and fecal score were recorded every day. A 5-point fecal scoring method was used: 1≤FS<2 indicated constipation, 2≤FS≤3 indicated normal, 3<FS≤4 indicated soft stools, and 4<FS≤5 indicated diarrhea.

[0137] 2.2 Determination of fur indexes

[0138] On the 0th day and the 25th day of the experiment, three professionals were assigned to score the hair and skin condition of each cat according to the scoring criteria and summarize the statistics.

[0139] Table 2 Pet cat fur scoring standards

[0140]

[0141] Note: Skin elasticity refers to how quickly the skin on the back recovers after being raised to a certain height.

[0142] On the 0th and 25th days of the test, the back hair was combed with a pet hair comb, and the combing was repeated 10 times. The fallen hair was collected and weighed and recorded using an analytical balance.

[0143] Hair samples were collected from the same part of each cat on the 0th and 25th days of the experiment. The hair on the back of each cat was shaved close to the skin with a pet-specific electric clipper, and the hair was placed in a sealed bag and numbered for storage. After that, the hair diameter, hair scale length and hair scale thickness of each sample were accurately measured using a scanning electron microscope, and the hair electron microscope images were saved for subsequent analysis.

[0144] Data Analysis:

[0145] The experimental data were subjected to independent sample t-test using SPSS26.0, and the results were expressed as "mean ± standard deviation". P < 0.05 indicated a significant difference, and P < 0.01 indicated an extremely significant difference.

[0146] 2.3 The results are as follows:

[0147] Body weight, food intake and feces scores

[0148] Table 3 Test results of Example 1 and Comparative Example 1 on pet cat weight, food intake and feces scores

[0149] project Comparative Example 1 Example 1 P-value Body weight on day 0 of the experiment (kg) 3.45±0.82 3.53±0.53 0.810 Body weight on the 25th day of the experiment (kg) 3.64±0.93 3.67±0.54 0.936 Average daily feed intake (g / d) 64.84±17.71 65.38±14.03 0.690 Fecal scoring 2.32±0.50 2.34±0.48 0.543

[0150] As shown in Table 3, during the test period, there was no significant difference in body weight, average daily feed intake and feces score between the cats of Comparative Example 1 and Example 1 on the 0th and 25th days (P>0.05). The body weight and feces score reflect the health status of the cats, indicating that the cats maintain a good healthy weight and feces. The average daily feed intake reflects the palatability of the pet dry food, indicating that the pet dry food has good palatability and cats like to eat it.

[0153]

[0154]

[0155] Note: Different lowercase fonts in the upper right corner indicate significant differences between the two groups.

[0156] As shown in Table 4, on the 0th day of the experiment, there was no significant difference in the fur condition of the cats of Example 1 and Comparative Example 1 (P>0.05). On the 25th day of the experiment, compared with Comparative Example 1, the hair luminance, hair smoothness, and skin elasticity of the cats fed with the pet dry food of Example 1 were significantly improved (P<0.01), which were 27.34%, 26.00%, and 18.05% higher, respectively, and the hair loss was significantly reduced (P<0.05), which was reduced by 25.64%.

[0157] See also Figure 2 , Figure 2 In the table, a represents "Comparative Example 1", b represents "Example 1", 0 represents the 0th day of the test, and 25 represents the 25th day of the test. Figure 2 It can be seen that after feeding the cat food for 25 days, the cats fed with the pet dry food of Example 1 had significantly more lustrous hair and were softer to the touch than the cats fed with the pet dry food of Comparative Example 1.

[0158] The results show that the cats in Example 1 have improved hair brightness, smoothness, and skin elasticity, and reduced hair loss. This means that cats get better nutrition, and receive and absorb better quality and more balanced hair-beautifying nutrients, such as beneficial essential fatty acids. These nutrients are essential for hair health and help hair grow healthier. The results can also reflect the improvement of the cat's overall health, such as good endocrine function and healthy skin condition.

[0159] 2.5 Analysis of hair-light microscope indicators

[0160] See also Figure 3 and Figure 4 , Figure 3 In the figure, a represents "Comparative Example 1", b represents "Example 1", 0 represents the 0th day of the test, and 25 represents the 25th day of the test.

[0161] It can be found through the hair scales (also called stratum corneum scale layer) of cat hair that the cats fed with the pet dry food of Example 1 have thinner hair scales than the cats fed with the pet dry food of Comparative Example 1. Thinner scales mean that the friction coefficient of the hair is smaller and the hair surface is smoother. This is manifested in the smooth and soft feel that the pet owner feels when stroking the cat's hair.

[0162] In summary, the present invention first adopts an emulsification process to combine safflower seed oil, fish oil, soybean oil and krill oil to form a composite oil, and then adopts an embedding process to process the perilla seed extract. The combination of the composite oil and the perilla seed extract can reduce cat hair loss, improve the softness and smoothness of cat hair, reduce the thickness of hair scales, help cats beautify their hair and skin, improve hair quality, and improve hair problems.
