Description

Technical Field

[0001] The invention relates to the technical field of pet dog food processing, and in particular to a processing method and a formula of chicken bone paste pet dog food. Background Art

[0002] Chicken bone paste is rich in protein and calcium and can be used as a high-quality raw material for pet dog food. The development of chicken bone paste pet dog food can effectively utilize the low-value scraps of the broiler processing industry (such as bone waste from boneless chicken feet, chicken frame bone waste after chicken breast meat is removed, etc.) to increase added value.

[0003] Since the protein and fat content in chicken bones are higher than those in pig bones, cattle bones, and sheep bones, the protein in chicken bones is a soluble full-price protein with high biological value. The protein content of chicken bones can reach 16.3%, which is equivalent to the same weight of chicken meat. Chicken bones are rich in amino acids and are a high-quality protein source. In addition, the ratio of calcium to phosphorus in chicken bones is 2:1, which is an appropriate ratio. Therefore, chicken bones have important comprehensive utilization and development potential.

[0004] Currently, the deep processing technology for chicken bones (residues) is imperfect and the technology is not yet mature. Most of them are directly discarded as kitchen waste or dried and then ground into powder and added to feed as a supplementary material. The overall added value is not high.

[0005] Therefore, a new processing method and formula of chicken bone paste pet dog food are urgently needed to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to provide a processing method and a formula of chicken bone paste pet dog food, which can optimize the deep processing technology of chicken bone paste, turn waste into treasure, and improve the economic value of chicken bone waste.

[0007] In order to achieve the above object, the present invention adopts such technical solution:

[0008] A method for processing chicken bone paste pet dog food is applied to the recycling of chicken bone waste, and the processing method at least comprises:

[0009] Get the main material parameters;

[0010] Determine the parameters of the main material. If the parameters of the main material are in the form of a slurry, classify and collect them for later use; if the parameters of the main material are in the form of a block and / or granules, perform slurry processing;

[0011] Material mixing: adding several auxiliary materials into the slurry-like main material according to a predetermined ratio, mixing the materials evenly to form a blank;

[0012] Cooking treatment, steaming the blank to obtain a preliminarily formed cooked product;

[0013] Modeling treatment, forming the cooked material into a regular structure;

[0014] The material after the shaping process is baked to produce Maillard reaction and caramelization reaction to obtain the finished product.

[0015] On the basis of the above technical solution, the slurry treatment at least includes:

[0016] Cleaning: washing, cleaning and draining the block and / or granular main material;

[0017] Dehydration and shaping: compress and shape the drained main material and collect the overflowing juice;

[0018] Crushing and grinding: the main material after dehydration and shaping is successively placed into the crushing equipment and the grinding equipment for processing to obtain the main material in a slurry state.

[0019] Based on the above technical solution, the working environment temperature of the slurry treatment is controlled not to exceed 15 degrees Celsius.

[0020] On the basis of the above technical solution, the main material is screened before dehydration and shaping to separate the block and granular main materials, and the granular main material is reciprocatingly rolled to obtain debris and mix it evenly with the block main material.

[0021] On the basis of the above technical solution, the juice collected during the dehydration and shaping is added during the mixing and / or maturation of the materials.

[0022] Based on the above technical solution, the juice is first concentrated after being collected.

[0023] On the basis of the above technical solution, during the baking process:

[0024] Get the color parameters of the material surface;

[0025] Determine the color parameter, compare the color parameter with the threshold parameter, if the color parameter is lighter than the threshold parameter, continue baking, or adaptively adjust the baking temperature; if the color parameter is equal to or darker than the threshold parameter, stop baking;

[0026] The threshold parameter is a reference color parameter obtained from a preliminary test.

[0027] On the basis of the above technical solution, the surface of the finished product is oiled.

[0028] On the basis of the above technical solution, the finished product is packaged.

[0029] A formula of chicken bone paste pet dog food is prepared by the above processing method, and the formula comprises at least 20 parts of chicken bone paste, 15 parts of fish meat, 10 parts of chicken liver, 23 parts of puffed corn flour, 10 parts of soybean meal, 5 parts of egg yolk powder, 10 parts of kelp powder, 0.5 parts of chicken fat and 0.1 parts of yeast nucleotide in parts by weight.

[0030] Compared with the prior art, the present invention has at least the following advantages:

[0031] 1. By recycling and utilizing chicken bone waste, the shortcomings of the existing deep processing technology for chicken bone waste can be overcome, which not only reduces the impact of waste on the environment, but also increases the economic value of chicken bones.

[0032] 2. By adding auxiliary materials, the taste and nutritional value of chicken bone paste pet dog food are improved, making it more in line with the needs of pets.

[0037] In order to make the purpose, technical scheme and advantages of the present invention clearer, a detailed description is given below in conjunction with the accompanying drawings and specific embodiments. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific implementation disclosed below.

[0038] Embodiment 1:

[0039] A processing method for chicken bone paste pet dog food is used for recycling chicken bone waste, specifically for pre-food chicken bone waste such as bone waste stripped from boneless chicken feet and chicken frame bone waste after chicken breast meat is removed, generated by broiler processing plants and chicken feet processing plants. Among them, the bone waste stripped from boneless chicken feet is mainly in a granular structure, and the chicken frame bone waste after chicken breast meat is removed is mainly in a block structure.

[0040] The processing method comprises: obtaining main material parameters, judging main material parameters, material mixing, aging treatment, shaping treatment and baking treatment.

[0041] The obtaining of the main material parameters in this embodiment refers to: manually observing the state of the main material to be processed.

[0042] Furthermore, the main material parameters are judged. If the main material parameters are in a slurry state (a semi-finished product that has been processed from chicken bone waste into a slurry-like chicken bone paste, which is a paste of chicken bones or chicken bone residue that has been ground into a certain particle size by a bone paste machine, also called bone paste), they are classified and collected for later use; if the main material parameters are in a block and / or granular state (pre-food chicken bone waste), a slurry treatment is performed, and the purpose of the slurry treatment is to make a slurry-like chicken bone paste.

[0043] The pulping process includes: cleaning, dehydration, shaping, and crushing and grinding.

[0044] The cleaning refers to washing and draining the block and / or granular main material, the purpose of which is to remove impurities on the surface of the main material. Specifically, the block and / or granular main material is placed in a clean water tank and stirred and rinsed.

[0045] The dehydration and shaping refers to: compressing and shaping the drained main material and collecting the overflowed juice. The main purpose is to remove excess water entrained on the main material after cleaning and to shape the main material into a smaller and relatively regular structure. During the shaping process (with the help of stamping equipment), the parts with more disordered structures and excessively accumulated structures can be broken or disassembled first to facilitate subsequent crushing processing.

[0046] It should be noted that the main material is screened before the dehydration and shaping, the block and granular main materials are separated, the granular main material is reciprocated and rolled (rolling is achieved by a roller module) to obtain debris and mix it evenly with the block main material. The main purpose of this step is to crush the granular chicken bones (mainly chicken feet bones) in advance. Chicken bones with this structure are relatively easy to crush, and the nutrients such as bone marrow and protein inside are relatively high. They can be exposed after being crushed in advance, and when they are subsequently mixed with the block main material and compressed and shaped, they can be discharged in large quantities along with the juice overflowing from other parts, thereby increasing the nutrient content in the juice. From another perspective, it is to give priority to collecting the main nutrients in advance to avoid the loss of nutrients caused by a large amount of nutrients adhering to the crushing equipment during subsequent crushing, resulting in difficulty in collection.

[0047] The working environment temperature of the pulping treatment is controlled to be no more than 15 degrees Celsius. Working in a low temperature environment is beneficial to insuring the materials and preventing the main materials from deteriorating.

[0048] In other embodiments, the juice is concentrated after being collected, specifically by boiling or adding a thickener, which is conducive to concentrating the essence and facilitating subsequent mixing, thereby preventing the material from being too thin after mixing, making it difficult to shape or having poor shaping quality.

[0049] The crushing and grinding means: putting the dehydrated and shaped main material into the crushing equipment and the grinding equipment successively for processing to obtain the slurry-like main material. It is the existing technology, and the specific structure and the working principle based on the structure during operation will not be repeated here.

[0050] The material mixing means: adding several auxiliary materials into the slurry-like main material according to a predetermined ratio, mixing the materials evenly, and making a blank. When the materials are mixed, the juice collected in the dehydration and shaping is added.

[0051] In this embodiment, the auxiliary materials include fish meat, chicken liver, puffed corn flour, soybean meal, egg yolk powder, kelp powder, chicken fat and yeast nucleotides.

[0052] Fish meat contains a lot of protein, which is essential for the growth and development of pet dogs. It not only provides energy, but also maintains the normal functioning of body tissues and hormones, and regulates acid-base balance, playing an important role. Bone-in fish meat increases the taste and flavor of the product and improves the protein and calcium content of the product.

[0053] Chicken liver is rich in amino acids, trace minerals and some fat-soluble vitamins, and serves as a high-quality attractant.

[0054] Puffed corn flour and soybean meal are rich in carbohydrates and are important sources of energy for pet dogs. Generally, plant-based feeds contain more carbohydrates, such as corn, soybean meal, etc.

[0055] Egg yolk powder is rich in lecithin, which is about 9.76% of egg yolk. Adding lecithin can increase the fat reserves in animals, provide beneficial nutrients such as choline, linolenic acid and linoleic acid, increase nutritional value, promote the digestion and absorption of lipids by pet dogs, and improve the hair and skin condition of pet dogs.

[0056] Kelp powder can also improve the immunity of pet dogs and promote their healthy growth. It also contains bioactive hormones that can regulate the body's metabolism and promote the digestion and absorption of nutrients.

[0057] Chicken oil can increase the oily taste of the product and improve the palatability of the product for pet dogs. In addition, chicken oil can also promote the fat digestion rate and growth performance of pet dogs and improve the quality of fur.

[0058] Yeast nucleotides have a great impact on the development, damage repair and intestinal immunity of the gastrointestinal tract of pet dogs.

[0059] The ripening process refers to: steaming the raw material to obtain a preliminarily formed ripened product. In this embodiment, the raw material is a mass, which is ripened after steaming, and has a relatively more stable structure, similar to a cake.

[0060] The shaping process refers to forming the cooked material into a regular structure, which can be achieved by cutting, pressing with a mold, granulating with a granulator, etc., to obtain a granular, rod-shaped, block-shaped or sheet-shaped structure.

[0061] The baking process refers to baking the material after the shaping process to produce Maillard reaction and caramelization reaction to obtain the finished product.

[0062] It should be noted that during the baking process: first obtain the color parameters of the material surface; then judge the color parameters, compare the color parameters with the threshold parameters, if the color parameters are lighter than the threshold parameters, continue baking, or adjust the baking temperature adaptively; if the color parameters are equal to or darker than the threshold parameters, stop baking. The threshold parameters are the reference color parameters obtained in the preliminary test. Specifically, they are benchmarked according to the data with better taste and flavor in the test results, and a color card for judgment and comparison is made, and one of the colors is used as the better benchmark for the end of baking. This is conducive to basically ensuring the standardization of the baking process, so that the taste and flavor of each batch of products remain basically the same, and the consistency of product quality is maintained stable.

[0063] During the baking process, spraying an appropriate amount of the juice collected during the dehydration and shaping onto the material is beneficial to preventing the product from drying and hardening after baking, and is also beneficial to improving the nutritional value of the product.

[0064] In other embodiments, the surface of the finished product is coated with oil, which can be animal oil, vegetable oil or synthetic oil. This is conducive to forming a wrapping on the outer surface of the product, reducing the contact between the internal structure and the external air, thereby extending the shelf life. In addition, the outer layer of oil can volatilize the fragrance and enhance the attractiveness of the product to pets.

[0065] In other embodiments, the finished product may also be packaged, such as by using a packaging bag, a paper box, etc.

[0066] Embodiment 2:

[0067] This embodiment discloses a method for processing chicken bone paste pet dog food, which is applied to a scenario where the main material is a semi-finished chicken bone paste. The processing method specifically includes:

[0068] (1) Thawing the raw materials: Thaw the chicken bone paste at room temperature until it becomes soft.

[0069] (2) Grinding: Put the bone-in fish meat into a grinder and grind it roughly, then grind it a second time to a particle size of about 50 mesh, and put it into a bowl for later use.

[0070] (3) Mixing and kneading: Use an electronic balance to weigh the raw materials and auxiliary materials in accordance with the test ratio and put them into a mixing bowl. Knead: Under room temperature, add 20% water and knead the chicken bone paste with each auxiliary material to fully blend them. Knead for 10 minutes and then put them into a steaming tray.

[0071] (4) Steaming: Place the kneaded mixture into a steamer and steam for 10 minutes to mature and initially shape it.

[0072] (5) Granulation: The cooked mixture is placed into a granulation mold and extruded into 6×6 mm granules, which are spread flat on a baking tray, with the distance between the granules being well controlled.

[0073] (6) Baking: The granulated mixture is baked in an oven at 180°C for 25 min to remove moisture, and Maillard reaction and caramelization reaction occur to release aromatic substances, making the product more flavorful.

[0074] (7) Cooling packaging: Packaging is performed after cooling to room temperature.

[0075] Embodiment 3:

[0076] A formula of chicken bone paste pet dog food is made by the above processing method. The formula comprises, by weight: 20g chicken bone paste, 15g fish meat, 10g chicken liver, 23g puffed corn flour, 10g soybean meal, 5g egg yolk powder, 10g kelp powder, 0.5g chicken fat and 0.1g yeast nucleotide.

[0077] Embodiment 4:

[0078] A formula of chicken bone paste pet dog food is prepared by the above processing method. The formula comprises, by weight: 10g chicken bone paste, 7g fish meat, 5g chicken liver, 10g puffed corn flour, 5g soybean meal, 3g egg yolk powder, 5g kelp powder, 0.2g chicken fat and 0.05g yeast nucleotide.

[0079] Based on the above examples, a single factor experiment was conducted to study the effects of water addition, cooking time, and baking time on product quality. Figure 1-Figure 3 . and get:

[0080] (1) Effect of water addition on product quality

[0081] The amount of water added affects the degree of integration between chicken bone paste and other auxiliary materials. If the amount of water added is too little, the mixture will be too dry, the granules will be cracked, and the color will be uneven due to insufficient integration. If the amount of water added is too much, the mixture will be too watery and wet and difficult to form. The product quality is best when the amount of water added is 20%.

[0082] (2) Effect of cooking time on product quality

[0083] If the cooking time is too short, the mixture is not formed and is not conducive to granulation. If the cooking time is too long, the corn flour of the product is more likely to age after being compounded with other materials, and the texture of the mixture after cooking is too hard, which is not easy to form during granulation. When the cooking time is 10 minutes, the sensory indicators of the product perform best under this condition.

[0084] (3) Effect of baking time on product quality

[0085] Baking time will affect the color, hardness and taste of the product. The possible reason is that the Maillard reaction during baking changes the color and flavor of the product. It may also be because the chicken fat in the product is easily burnt by the high temperature during baking. Dogs are very resistant to the smell of burnt, especially dogs with a more sensitive sense of smell. If the baking time is too short, the Maillard reaction is not sufficient, which will cause the product to be too light in color, soft in hardness, and soft in taste. If the baking time is too long, the Maillard reaction is excessive, which will cause the product to be too brown in color, too hard in hardness and taste. It is best to bake in an oven at 180℃ for 25 minutes.

[0086] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
