[0001] The invention belongs to the technical field of pet food, and in particular relates to a collagen pet tooth-cleaning bone and a preparation method thereof. Background Art

[0002] As people pay more and more attention to the health of pets, oral health issues have gradually become an important topic. The main oral problems of dogs include dental fungus, dental calculus, gingivitis, periodontitis and bad breath, which not only cause eating disorders and secondary respiratory infections in dogs, but are also related to a variety of systemic diseases, such as intestinal diseases, heart disease, kidney disease and diabetes, which seriously affect the quality of life of pets and the close relationship between people and pets. Clinically, in most cases, symptomatic treatment can only be carried out according to the more serious oral symptoms that have appeared, which not only brings pain to pets, but also generates a high cost of treatment. Therefore, it is of great significance to strengthen daily care and preventive measures for the oral health of dogs.

[0003] At present, there are various pet tooth cleaning products on the market, including tooth cleaning bones. Tooth cleaning bones are edible raw materials prepared into a hard, wear-resistant, food-resistant state suitable for pets to chew for a long time. Teeth are cleaned by chewing the tooth cleaning bones. At present, some tooth cleaning bone products, in order to increase the cleaning effect of the product, often maintain the hardness of the tooth cleaning bone at a very high level, or add a large amount of abrasive ingredients to the raw materials, but this often leads to more serious pet tooth wear problems, and may also cause pet gums to be scratched and bleed. Therefore, it is necessary to develop a new tooth cleaning bone product that can achieve the tooth cleaning function while avoiding tooth wear and gum injury. Summary of the invention

[0004] The present invention is intended to provide a collagen pet tooth cleaning bone to solve the problem that high-hardness tooth cleaning bones can cause serious wear of pet teeth.

[0005] In order to achieve the above-mentioned purpose, the scheme of the present invention is: a collagen pet tooth cleaning bone, whose raw materials include, by weight: 60-100 parts of collagen, 10-30 parts of meat, 0-20 parts of edible powder, 1-10 parts of glycerol, 1-3 parts of potassium sorbate, and 0.2-1 parts of vitamin E. Its raw materials also include seaweed extract and coconut oil. The amount of seaweed extract added is 0.1-0.5% of the quality of collagen, and the amount of coconut oil added is 1-5% of the quality of collagen.

[0006] Optionally, the raw materials include, by weight: 60 parts of collagen, 10 parts of meat, 10 parts of edible powder, 5 parts of glycerin, 2 parts of potassium sorbate, and 0.5 parts of vitamin E. The raw materials also include seaweed extract and coconut oil. The amount of seaweed extract added is 0.5% of the mass of collagen, and the amount of coconut oil added is 5% of the mass of collagen.

[0007] Optionally, the collagen is one or more of chicken collagen, bovine collagen, fish collagen, duck collagen and porcine collagen.

[0008] Optionally, the meat is one or more of chicken, duck, beef, fish, chicken meal, duck meal, beef meal and fish meal.

[0009] Optionally, the edible flour is one or more of tapioca starch, corn starch, sweet potato starch, potato starch, pea starch, wheat starch, tapioca flour, corn flour, sweet potato flour, potato flour, pea flour, wheat flour and peanut protein powder.

[0010] The present invention also intends to provide a method for preparing collagen pet tooth-cleaning bone, comprising the following steps:

[0011] S1. Raw material pretreatment: using flavor protease to enzymatically hydrolyze the collagen raw material at 50°C and pH 6.5 for 3 to 3.5 hours; after the enzymatic hydrolysis is completed, the temperature is raised to 100°C, maintained at a constant temperature for 1 hour, and then cooled to room temperature to obtain a treated material;

[0012] S2, mixing ingredients: meat, edible flour, glycerin, potassium sorbate, vitamin E, seaweed extract, coconut oil and the treated material obtained in step S1 are mixed and stirred, and water is added during the stirring process, and the amount of water added is 20-40% of the sum of the weight of each raw material to obtain a wet mixture;

[0013] S3, molding: the wet mixture obtained in step S2 is subjected to an extrusion molding process to obtain a molding material; or the wet mixture obtained in step S2 is subjected to an extruder to obtain a strip material and then manually molded to obtain a molding material;

[0014] S4, baking: the molded material obtained in step S3 is placed in 80-120°C and baked for 3-8 minutes to fix the shape, and then transferred to 35-65°C and baked for 10-20 hours. After cooling, a tooth cleaning bone product is obtained.

[0015] In step S1, the amount of flavor protease used is 2-2.5% of the amount of collagen.

[0016] Optionally, in step S4, the water content of the tooth cleaning bone product is 8-15%.

[0017] The working principle and beneficial effects of this scheme are: collagen is used as the main raw material in this scheme, supplemented with seaweed extract and coconut oil, and the obtained tooth cleaning bone product is like rubber, soft but tough, and the pet will not seriously wear out the teeth during the chewing process. Moreover, in the process of pet chewing the tooth cleaning bone, the friction between the pet's teeth and the tooth cleaning bone can effectively slow down the formation of tartar and dental plaque. In addition, seaweed extract contains minerals such as calcium, potassium, magnesium, etc., which can help strengthen teeth, reduce the occurrence of tooth decay, inhibit oral bacteria, reduce tartar and bad breath, and reduce gingivitis; coconut oil is rich in lauric acid, which can kill oral bacteria and reduce dental plaque and bad breath. In this way, in this scheme, collagen is used as the main raw material, and seaweed extract and coconut oil are used in combination to enhance the tooth cleaning effect of the tooth cleaning bone, thereby effectively reducing pet bad breath, slowing down the formation of tartar and dental plaque, and avoiding serious wear of pet teeth.

[0070] Experimental example

[0071] All dogs were given blood routine and biochemical tests to ensure that they were in good health. The dogs were anesthetized and then cleaned with an ultrasonic dental scaler. After cleaning, the Halimeter bad breath detector was used to measure VSC (Volatilesulfur compounds, dog breath is mainly caused by volatile sulfides) as the dog's breath value. After the breath value was measured, the dogs were scored for dental plaque and calculus, so that the dog's dental plaque and calculus score was 0. The scoring operation and scoring criteria for dental plaque and calculus are as follows:

[0072] 1) Plaque score

[0073] a) Scoring procedure: Use dental plaque coloring solution to evenly smear the surface of the dog's teeth. After staining for 2 minutes, record the stained area.

[0074] b) The scoring criteria are shown in Table 1.

[0075] Table 1 Dental plaque scoring criteria

[0076] Coverage Score (Cs) Plaque staining area 0 No plaque 1 Staining area <25% 2 25%<Staining area≤50% 3 50%<stained area≤75% 4 Staining area>75%

[0077] 2) Dental calculus scoring

[0078] a) Scoring procedure: Brush off the plaque developer and plaque, rinse the teeth with pure water and air-dry them, and record the tartar coverage area on the tooth surface.

[0079] b) The scoring criteria are shown in Table 2.

[0080] Table 2 Scoring criteria for dental calculus

[0081] Coverage score (Cs) Tartar coverage area 0 No tartar 1 Coverage 1-24% 2 Coverage 25-49% 3 Coverage 50-74% 4 Coverage>75%

[0082] The dogs were randomly divided into a control group and four experimental groups, with 5 dogs in each group. The dogs were fed with two meals of staple food at regular intervals every day. 2 hours after feeding the staple food, the dogs in the control group and the four experimental groups were fed with 30 g of the pet tooth-cleaning bone in Comparative Example 1 and the collagen pet tooth-cleaning bone in Examples 1-4, respectively. The experiment lasted for 30 days, during which the dogs were allowed to drink water freely. The health status of the dogs was checked and the weight was recorded by a veterinarian every 10 days.

[0083] After the experiment, the dogs in the control group and the experimental group were tested for breath value and dental plaque and calculus scores. The results are shown in Table 3.

[0084] Table 3 Breath score, dental plaque score and dental calculus score of dogs in the control group and each experimental group

[0085]

[0086] As shown in Table 3, the experimental group is significantly lower than the control group in terms of breath value, dental plaque score and dental calculus score, which indicates that the collagen pet tooth cleaning bone in the present invention has a better oral cleaning effect, can effectively reduce pet bad breath, and effectively slow down the formation rate of dental plaque and dental calculus. Moreover, by comparing the data of the four experimental groups, it can be found that the effect of experimental group 2 is the best, which indicates that the optimal addition amount of seaweed extract is 0.5% of the collagen protein quality, and the optimal addition amount of coconut oil is 5% of the collagen protein quality.
