Technical Field

[0001] The invention relates to the technical field of pet food production, and in particular to a method for producing pet food by utilizing reconstituted poultry by-product meat. Background Art

[0002] With the improvement of people's living standards and the change of pet-raising concepts, pets have become important members of many families. The pet food market has therefore shown a rapid growth trend. Consumers are also increasingly demanding the quality, nutrition and safety of pet food.

[0003] With the rapid development of the poultry farming industry, the amount of poultry by-products produced has also increased. These by-products include minced meat, scraps, and offal. If not properly handled, they will not only cause a waste of resources, but may also pollute the environment. Therefore, the development of poultry by-product reconstituted meat production pet food technology can effectively utilize these resources, reduce waste, and reduce environmental pollution, which meets the requirements of sustainable development.

[0004] Restructured meat technology is a technology that reassembles minced meat, scraps, etc. into complete meat blocks or minced meat by adding adhesives. This technology has been widely used in the field of livestock and poultry product processing, but its application in the field of pet food is still in its infancy. Carrying out relevant technical research and development can promote technological innovation and industrial upgrading in the pet food industry and improve the added value and market competitiveness of products.

[0006] To achieve the above object, the present invention adopts the following technical solution: A method for producing pet food using reconstituted poultry by-product meat comprises the following steps: (1) Raw material collection and processing: Collect by-product raw materials generated during poultry slaughtering and pre-treat the raw materials to ensure their hygiene and safety; (2) Component extraction: Extract nutrients from poultry by-products using biotechnology; purify and modify the extracted ingredients by physical or chemical methods; (3) Protein Recombination: The extracted nutrients are reorganized to form a fibrous structure with meat characteristics; the taste and texture of the recombinant protein are improved by adding food additives; (4) Molding and processing: The mixture of recombinant protein and seasoning is processed into the shape of pet food through extrusion and molding processes; the product's maturity is improved through heat treatment processes, while sterilization is achieved at the same time.

[0007] Preferably, in step (1), the frozen livestock and poultry by-products are thawed at low temperature, washed, and then crushed using a 0.5 cm hole.

[0008] Preferably, in step (2), the minced meat is added with plasma protein powder and then placed in a meat grinder and stirred until it becomes a meat paste.

[0009] Preferably, in step (2), the meat grinder adopts an intermittent working mode to prevent excessive temperature from damaging the protein structure, and the mixer stops for 5-6 seconds after every 10-15 seconds of working.

[0010] Preferably, in step (3), yeast extract, heme peptide and sodium caseinate are added to the meat paste prepared in step (2) in sequence, the mixture is thoroughly mixed and stirred, and the mixture is placed in a molding mold to shape the meat paste into a meat patty.

[0011] Preferably, the meat patties formed in step (3) are placed in an ice water bath, and the probe of an ultrasonic cell disruptor is inserted 20-25 mm below the water surface of the ice water bath for ultrasonic treatment.

[0012] Preferably, in step (4), the product is cooked in a steamer at a temperature above 100° C. to obtain the product.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention not only solves the problem of poultry by-product treatment and reduces environmental pollution, but also meets the The pet market has a demand for high-quality and diversified food. The research results are expected to promote the sustainable development of the pet food industry and promote the formation of a circular economy and green production model. DETAILED DESCRIPTION

[0014] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the preferred embodiments.

[0015] A method for producing pet food using reconstituted poultry by-product meat of the present invention comprises the following steps: (1) Raw material collection and processing: Collect by-product raw materials generated during poultry slaughter, such as feathers, bones, and viscera, thaw the frozen livestock and poultry by-products at low temperature, clean, disinfect, remove impurities, and then crush them using a 0.5 cm hole.

[0016] (2) Component extraction: Use biotechnology to extract nutrients such as protein, fat, minerals, etc. from poultry by-products; purify and modify the extracted ingredients through physical or chemical methods.

[0017] Specifically, the minced meat is added with plasma protein powder and then placed in a meat grinder and stirred until it is in a meat paste state. The meat grinder adopts an interval working mode to prevent the excessive temperature from damaging the protein structure, and the mixer stops for 5-6 seconds every 10-15 seconds.

[0018] (3) Protein Recombination: The extracted protein is reorganized through physical methods such as heating, shearing, pressure, or biological methods such as enzyme treatment to form a fibrous structure with meat characteristics; the taste and texture of the recombinant protein are improved by adding appropriate amounts of food additives (such as emulsifiers, stabilizers, etc.).

[0019] Specifically, yeast extract, heme peptide and sodium caseinate are added to the meat paste prepared in step (2) in sequence, the mixture is thoroughly mixed and stirred, and the mixture is placed in a molding mold to form the meat paste into a meat patty. The formed meat patties are placed in an ice water bath, and the probe of an ultrasonic cell disruptor is inserted 20-25 mm below the water surface of the ice water bath for ultrasonic treatment.

[0020] (4) Flavor modulation Analyze the needs of pets for different flavors, and add appropriate amounts of seasonings and flavor enhancers, such as amino acids, nucleotides, etc., to enhance the flavor of reconstituted meat.

[0021] (5) Molding and processing: The mixture of recombinant protein and seasoning is processed into the shape of pet food through extrusion, molding and other processes; the product's maturity is improved through heat treatment processes such as baking and steaming, while sterilization is achieved at the same time.
