Description

Technical Field

[0001] The invention relates to the technical field of pet food processing and manufacturing, in particular to pet food with added vitamins, containing fish-derived raw materials and having the effects of beautifying hair and skin. Background Art

[0002] With the passage of time and improvements in living standards, more and more people are keeping pets. Furthermore, with the growth of the pet industry and increasing awareness among pet owners about their pet's health, people are beginning to pay attention to how pet food affects their pet's appearance, particularly the health of their skin and coat. The skin is a pet's largest organ, not only protecting it from environmental hazards but also affecting its comfort and appearance. Healthy skin and coat are crucial to a pet's overall health and well-being.

[0003] Nutritionally, skin and coat health is closely linked to specific nutrients. For example, omega-3 and omega-6 fatty acids are crucial for maintaining the skin's barrier function and promoting coat luster. Omega-3 fatty acids, particularly EPA and DHA, can reduce skin inflammation and improve dandruff and itching, while omega-6 fatty acids, such as linoleic acid, are equally important for coat growth and skin health. Therefore, pet foods containing these nutrients are needed to meet pets' coat and skin needs. These products often achieve this through the addition of fish oil, flaxseed oil, vitamins, and trace elements.

[0004] Existing pet foods typically utilize a traditional puffing process, namely hot-wet extrusion, one of the most common methods used in pet food production. This process involves heating and pressurizing the raw material mixture and extruding it through a specifically shaped die. The instantaneous release of heat and pressure causes the food to expand and form, and the product is then dried. While this process can provide pet food with a better taste and ease of storage and transportation, it can also result in a loss of nutrients.

[0005] Therefore, it is necessary to develop a pet food with a more reasonable ratio and a suitable production method. Summary of the Invention

[0006] To address the limitations of the prior art, the present invention provides a pet food containing fish-derived ingredients and vitamins, which has coat and skin beautifying properties, and a method for preparing the same. The present invention also provides a novel pet food production method that minimizes nutrient loss. The pet food not only meets the nutritional needs of pets but also provides excellent coat and skin care.

[0007] To achieve the above object, the present invention is realized through the following technical solutions: On the one hand, the present invention provides a pet food with the efficacy of beautifying hair and skin care containing fish-derived raw materials and added vitamins, comprising the following raw materials in parts by weight: 0.2-0.5 parts of vitamin E, 8-16 parts of salmon, 1-5 parts of salmon fish oil, 50-60 parts of chicken, 10-15 parts of chicken liver, 10-15 parts of chicken heart, 2-5 parts of sweet potato powder, 1-5 parts of brewer's yeast powder, 2-5 parts of chicken oil, 1-2 parts of plantain powder, 1-2 parts of chicory root powder, 1-2 parts of cellulose, 0.5-2 parts of egg yolk lecithin, 0.2-0.8 parts of polyglycerol fatty acid ester, 5-20 parts of water, and 0.05-0.1 parts of agar.

[0008] The present invention does not achieve the corresponding effect by adding a single hair-beautifying raw material, but realizes the effect of beautifying hair and skin care through a triple combination form, namely, the combination form of fish-derived fresh meat, the combination form of fresh salmon and salmon oil, and the combination form of prebiotics, and adds vitamin E to antioxidant.

[0009] Among them, in the combination form of fresh salmon and fresh chicken, the content of omega-6 in fresh chicken is relatively high, and its high content will cause inflammatory reactions, while the content of omega-3 in salmon is high, which can effectively balance the relationship between the two; and what is used in the market is salmon powder and frozen salmon, and a large amount of nutritional components such as unsaturated fatty acids are lost. The salmon added in this formula is fresh salmon cultured in Xinjiang glacier live water and transported by a 0-4°C cold chain throughout the process, which greatly retains the freshness and nutritional value of the raw materials.

[0010] The present invention also adopts the combination form of fresh salmon and salmon oil. Both salmon and salmon oil are rich in omega-3, which can effectively regulate the hair growth factor, promote hair growth; promote the repair of the epidermal barrier; prevent the oxidation and aging of hair follicles; promote the metabolism of saturated fatty acids and prevent fat deposition; and can also improve immunity, reduce the risk of inflammation and itching, and effectively care for the health of hair.

[0011] The present invention also adds prebiotics, which can effectively regulate the intestinal health of pets and better digest and absorb nutrients.

[0012] As a preferred embodiment, the salmon is fresh salmon; the chicken is fresh chicken. As a preferred embodiment, the chicken liver is fresh chicken liver; the chicken heart is fresh chicken heart.

[0013] On the other hand, the present invention also provides a preparation method of the foregoing pet food with the efficacy of beautifying hair and skin care containing fish-derived raw materials and added vitamins, specifically comprising the following steps:

[0014] (1) Preparation of meat paste: Beat salmon, chicken, chicken liver, and chicken heart into meat paste respectively, then mix them evenly, and cook and gelatinize them to obtain meat paste;

[0015] (2) Preparation of the sandwich layer: Take a part of the meat paste, cool it, and mix it with chicory root powder, psyllium powder, a part of water, egg yolk lecithin, and polyglycerol fatty acid ester. After rapid stirring, it is freeze-dried to obtain Carrier 1.

[0016] Add the salmon fish oil and vitamin E mixture to Carrier 1 so that Carrier 1 fully adsorbs the salmon fish oil and vitamin E to obtain Carrier 2.

[0017] Spray the agar aqueous solution onto Carrier 2 and let it stand to obtain the sandwich layer.

[0018] (3) After cooling the remaining meat paste and fully mixing it with the remaining raw materials, a mixed meat paste is obtained. Then, first spread a layer of the mixed meat paste in a mold, then place the sandwich layer on the mixed meat paste, and then spread a layer of the mixed meat paste on the sandwich layer. Optionally, repeat the above steps of laying the mixed meat paste and the sandwich layer. After molding using the mold, it is sterilized to obtain the pet food.

[0019] Salmon fish oil is rich in Omega-3 fatty acids. Especially, the two main components, EPA and DHA, contain a large number of unsaturated bonds. These unsaturated bonds are extremely unstable and are easily affected by environmental factors such as air and light and undergo oxidation reactions. Once the oxidation process starts, hydroperoxides will be rapidly formed and further decomposed to produce aldehydes and ketones, resulting in the fish oil having a rancid odor and taste changes. At the same time, free radicals and peroxidized lipids are produced, which may have an adverse impact on cardiovascular health. Therefore, in order to solve the problem that salmon fish oil in pet food is easily oxidized, the present invention specifically designs the above sandwich layer.

[0020] In the above sandwich layer of the present invention, take a part of the meat paste, cool it, and mix it with chicory root powder, psyllium powder, a part of water, egg yolk lecithin, and polyglycerol fatty acid ester. After rapid stirring, a large number of bubbles will be generated in the above mixed system. Then, freezing the above mixed system containing a large number of bubbles will produce Carrier 1 with a rich pore structure. Using the pore structure of Carrier 1, the vitamin E and salmon fish oil mixture can be adsorbed in large amounts, so that the vitamin E and salmon fish oil mixture is limited in Carrier 1 to form Carrier 2. Spraying agar solution on the outer layer of Carrier 2 can form an agar shell, thus preventing the vitamin E and salmon fish oil mixture from flowing out of Carrier 1, effectively solving the problem that salmon fish oil is easily oxidized in pet food.

[0021] In addition, the egg yolk lecithin and vitamin E in the sandwich layer also have antioxidant properties. Limiting them together with the salmon fish oil in the sandwich layer is also beneficial to preventing the oxidation of the salmon fish oil.

[0022] As a preferred embodiment, in step (2), the mass ratio of meat puree, chicory root powder, psyllium powder, part of water, egg yolk lecithin, and polyglycerol fatty acid ester is 3-6: 1-2: 1-2: 12: 0.5-2: 0.2-0.8.

[0023] As a preferred embodiment, in step (2), the rate of rapid stirring is 2000-2800 revolutions per minute; the time of rapid stirring is 0.5-2 hours.

[0024] As a preferred embodiment, in step (2), the temperature of freeze-drying is -20 to -30 °C; the time of freeze-drying is 40-80 minutes.

[0025] As a more preferred embodiment, in step (2), the freeze-drying of the present invention is first carried out at normal pressure at -20 to -30 °C; the freeze-drying time is 5-20 minutes, then it is treated in an ultrasonic wave with a power of 40-60 w for 1-2 minutes; then it is placed under a vacuum of 10-12 KPa at -20 to -30 °C and dried for 5-10 minutes, and then at normal pressure at -20 to -30 °C and dried for 30-40 minutes.

[0026] The present invention further optimizes the above freeze-drying process for the sandwich layer. The present invention finds that first, in the first-stage normal-pressure freezing, carrier one is shaped first, and based on the bubble structure inside carrier one, certain pores will be generated inside it. Then, under the action of ultrasonic waves in the second stage, the bubbles in carrier one will overflow. The process of bubble merging and overflowing will form new pore diameters in carrier one. Then, in the third-stage vacuum freezing, under the decompression effect, the bubbles will escape faster, and at this time, new pore diameters will be formed in carrier one. Finally, it is frozen and shaped at normal pressure and dried. In this way, the freeze-drying after the above optimization will make the sandwich layer have richer pore diameters, and it is also more conducive to adsorbing more vitamin E and salmon fish oil mixture, thus better avoiding the problem that salmon fish oil is easily oxidized in pet food.

[0027] As a preferred embodiment, in step (2), in the agar aqueous solution, the mass ratio of agar to water is 1: 80-100.

[0028] As a preferred embodiment, in step (2), after cooling carrier two to 2-6 degrees, the agar aqueous solution is then sprayed onto carrier two and left standing for 30-50 minutes.

[0029] As a preferred embodiment, in step (2), sterilization is carried out by ultraviolet light irradiation sterilization.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] (1) The formula of the present invention is reasonable. The prepared pet food can not only meet the nutritional needs of pets, but also play a good role in fur care and improve the skin condition of pets.

[0032] (2) The sandwich layer made by the freeze-drying process in the present invention enables pets to chew when eating and maintain the taste for a long time, improving their satiety.

[0033] (3) The sandwich layer made by the freeze-drying process in the present invention adopts a clever structural design, which can effectively avoid the problem of fish oil oxidation, greatly retain the original nutrients of the raw materials, and reduce nutrient loss. Specific Embodiments

[0063] Example 5

[0064] Compared with Example 1, the difference is only that first under normal pressure, at -25°C; the freeze-drying time is 15 minutes, then it is treated in ultrasonic waves with a power of 50w for 2 minutes; then it is placed under a vacuum of 10KPa, at -25°C, dried for 8 minutes, and then under normal pressure, at -25°C, dried for 35 minutes.

[0065] Comparative Example 1

[0066] It adopts a preparation method basically the same as that of Example 1, the difference is only that the mass ratio of meat paste, chicory root powder, plantain powder, part of water, egg yolk lecithin, and polyglycerol fatty acid ester is different from that of Example 1, and the mass ratio of its meat paste, chicory root powder, plantain powder, part of water, egg yolk lecithin, and polyglycerol fatty acid ester is 2:3:3:12:1:1.

[0067] Comparative Example 2

[0073] Among them, the mass of the vitamin E and salmon fish oil mixture adsorbed by carrier one = the total mass of the vitamin E and salmon fish oil mixture - the mass of the remaining vitamin E and salmon fish oil mixture after carrier one adsorbs the vitamin E and salmon fish oil mixture.

[0074] The overflow rate refers to applying pressure to carrier two and calculating the overflow rate of the liquid in carrier two. The calculation formula for the overflow rate of the liquid in carrier two is: the mass of the overflowed liquid in carrier two / the mass of the vitamin E and salmon fish oil mixture adsorbed by carrier one;

[0075] Among them, the mass of the vitamin E and salmon fish oil mixture adsorbed by carrier one = the total mass of the vitamin E and salmon fish oil mixture - the mass of the remaining vitamin E and salmon fish oil mixture after carrier one adsorbs the vitamin E and salmon fish oil mixture.

[0076] Adsorption time: refers to the time when carrier one adsorbs the vitamin E and salmon fish oil mixture.
