Description

Technical Field

[0001] The present invention relates to the field of pet food, and more particularly, to a complete pet food and a preparation method thereof. Background Art

[0002] Existing canned meat products, such as meat chunks and shredded meat for pets, are usually made by heating the meat and then processing it into a specific shape, then adding concentrated juice to mix, and finally sealing and sterilizing. Currently, this type of product can only be made into an ordinary canned snack product and cannot add mineral elements. If mineral elements are to be added, the iron, manganese, copper, zinc and other elements will accelerate the Maillard reaction of the protein in the meat, producing dark black substances or discoloration due to high-temperature oxidation, causing the overall color of the product to be black, affecting the appearance of the product, which is difficult for consumers to accept.

[0003] In view of this, we propose a complete pet food and a preparation method thereof. Summary of the invention

[0004] In order to solve the problem that the overall color of meat blocks and shredded meat cans becomes darker after sterilization, the present invention provides a complete pet food and a preparation method, which can not only ensure that the meat blocks and shredded meat cans are added, but also ensure that the color change phenomenon caused by chemical reaction will not occur after the addition of mineral elements.

[0040] Special mineral element materials provide metal elements, among which protein enzymes decompose proteins to form peptides, which chelate part of the full-valent metal ion solution, reducing the use of chelating agents. The peptides and metal ion chelation products also have nutritional value, which are easy for animals to decompose into peptides and metal ions, and can provide amino acids for pets. Chelating agents also chelate with full-valent metal ion solutions to improve the bioavailability of minerals and prevent metal ions from interacting with other nutrients. Full-valent metal ion solutions provide essential mineral elements; participate in the maintenance of enzyme system activity; support bone and tooth development; and maintain normal metabolism. Water is used to adjust the moisture content of the product, dissolve and disperse other nutrients, ensure the appropriate physical properties of the product, and help digestion and absorption. Vitamin premix: Provide comprehensive vitamin supplements; support energy metabolism; maintain fur health; enhance immune function. Among them, calcium carbonate or calcium hydrogen phosphate; supplement calcium, support bone development; regulate acid-base balance; participate in blood coagulation; maintain neuromuscular function.

[0073]

[0074] Example 4

[0075] A method for preparing complete pet food comprises the following steps:

[0076] S1. Pretreatment of high-quality protein: adding high-quality protein, water and protease into a blender for stirring, hydrolyzing the protease to obtain hydrolyzed protein,

[0077] S2. Initial chelation treatment: Put the full-valent metal ion solution into a blender and mix it with the hydrolyzed protein to ensure that the materials are fully mixed and evenly for initial chelation;

[0078] S3, secondary chelation treatment: adding the chelating agent into the mixer and continuing to stir, so that the chelating agent and the remaining metal ions are chelated to obtain a special material for mineral elements;

[0079] S4, aging treatment: boil and aging the fresh meat, and then cut it into meat cubes or shredded meat;

[0080] S5, mixing process; mixing the soup and the special material of mineral elements with the meat chunks to obtain a semi-finished product; using a filling machine to quantitatively fill and seal the semi-finished product.

[0081] According to one aspect of the embodiment of the present application,

[0082] In step S1, the pH value of the high-quality protein pretreatment is 2-8, and the high-quality protein pretreatment temperature is 36-60°C.

[0083] According to one aspect of the embodiment of the present application,

[0084] The pH value of the primary chelation treatment and the secondary chelation treatment is 6.2-6.5, and the chelation temperature is 35-40°C.

[0085] According to one aspect of the embodiment of the present application,

[0086] The following steps are also included:

[0087] S6. Place the sealed semi-finished products into a sterilizer for high-temperature sterilization, and accelerate pressurized cooling after sterilization; place the sterilized semi-finished products into an insulation warehouse for insulation, and package and store them after insulation; the sterilization temperature is 118℃~121℃, and the sterilization time is 30~50min; the insulation temperature is 40±2℃, and the insulation time is 7-10 days.

[0088] In the S1 step, under specific pH and temperature conditions, the protease can reach its optimal activity state. When the protein and the protease are fully in contact in the blender, the protease will hydrolyze the large molecular protein and break it down into small molecular peptides and amino acids that are easier for animals to absorb.

[0089] Step S2 utilizes the good chelating ability of small molecule peptides and amino acids produced after hydrolysis. When the full-valent metal ion solution is mixed with the hydrolyzed protein, the amino and carboxyl groups in the amino acid molecules will form coordination bonds with the metal ions, thereby generating stable amino acid-metal chelates, which are more easily absorbed by the organism.

[0090] The S3 step is a supplement and optimization of the S2 step. The addition of professional chelating agents can combine with metal ions that are not fully chelated with amino acids in the S2 step to form a more stable chelate structure, thereby maximizing the bioavailability of metal elements and preventing metal ions from being oxidized during subsequent storage.

[0091] Step S4 mainly processes fresh meat. Under high temperature conditions of 90-100°C, the protein in the meat is denatured and the fiber tissue is softened, which not only improves the digestibility of meat protein but also kills potential harmful microorganisms. At the same time, the operation of cutting or slicing increases the surface area of ​​the meat, which is conducive to subsequent mixing with other raw materials.

[0092] Step S5 integrates the products of all previous steps. The soup contains water-soluble nutrients and flavor substances, and the mixture with mineral element special materials and meat blocks ensures the uniform distribution of nutrients; the final quantitative filling and sealing ensures the uniformity of product specifications, and can prevent the loss of nutrients and microbial contamination, providing protection for the storage and transportation of the product.

[0093] Step S6 includes two important subsequent processing links. First, high-temperature sterilization treatment at 118-121°C is carried out in the sterilizer. This temperature range can effectively kill heat-resistant spores and microorganisms in the product. The treatment time of 30-50 minutes ensures thorough sterilization. Pressurized cooling is carried out immediately after high-temperature sterilization. This rapid cooling can prevent the product from being continuously heated and affecting the nutritional components, and prevent the heat-resistant bacteria from reviving during the cooling process; the subsequent 40±2°C constant temperature insulation link lasts for 7-10 days. This stage is actually a safety verification process. Long-term observation at a temperature suitable for microbial growth can effectively test the sterilization effect and ensure the sterility and stability of the product. If there is no deterioration at this stage, it can be proved that the product has met the requirements of commercial sterility. The final packaging and warehousing are preparations for the storage and transportation of the product.

[0094] The above embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or changes made by those skilled in the art based on the present invention are within the protection scope of the present invention. The protection scope of the present invention shall be subject to the claims.
