Description
Technical Field
The invention relates to the technical field of pet tooth cleaning products, in particular to a pet tooth cleaning bone with an oral cavity cleaning function.
Background
With the continuous development of society, the oral cavity problem of pets gradually becomes the focus of attention of pet breeders, because the health of the oral cavity of pets directly influences the health and the living quality of pets. In the face of the requirements, the tooth cleaning product for the pet is produced, wherein the tooth cleaning bone is formed by preparing edible raw materials into a state that the tooth cleaning bone is hard, wear-resistant, high in food tolerance and suitable for being chewed by the pet for a long time, and the pet can bite the tooth cleaning bone to clean teeth. The teeth cleaning bone can promote salivary secretion through the chewing process of pets, and in addition, the teeth cleaning bone contains some antibacterial substances and abrasives, so that the teeth cleaning bone can resist oral bacteria, clean teeth and protect teeth.
In order to increase the cleaning effect of the existing tooth cleaning bone products, the hardness of the tooth cleaning bone is maintained at a higher level or a large amount of an abrasive component is added into the raw materials. The above operation causes a problem of more serious tooth abrasion of the pet. If the pet chews the clean tooth bone with high hardness and high content of the abrasive for a long time, teeth are abraded greatly and cannot regenerate, and symptoms such as periodontitis, gingivitis and the like are easy to appear. In the above situation, the quality of life of the pet is greatly compromised. In addition, if the hard bone is accidentally swallowed by the pet in pieces, the edges of the pieces may be sharp, and the esophagus and the oral cavity may be damaged during swallowing, so that oral and esophageal diseases are caused. Especially for old dogs, the dogs are easy to suffer from periodontal diseases, and serious dogs even die of pet dogs. In view of the above problems and needs, there is a need to develop a bone product for cleaning teeth, which has good oral cavity cleaning ability and can greatly reduce the oral cavity abrasion and oral diseases of pets.
Disclosure of Invention
The invention aims to provide a pet tooth cleaning bone with an oral cavity cleaning function, and aims to solve the technical problems that pet food in the prior art is not ideal in pet tooth cleaning effect and large in side effect.
In order to achieve the purpose, the invention adopts the following technical scheme:
the pet tooth cleaning bone with the oral cavity cleaning function comprises the following raw materials in percentage by mass: 25-45% of rice flour, 8-22% of chicken, 10-20% of sweet potato starch, 5-20% of pea starch, 4-10% of maltodextrin, 4-15% of glycerol, 0.5-5% of calcium carbonate, 0.2-2% of vegetable oil, 0.1-2% of casein phosphopeptide, 0.1-2% of sodium hexametaphosphate, 0.1-1% of baking soda, 0.05-2% of chlorogenic acid, 0.05-2% of tea polyphenol, 0.05-2% of magnolol extract, 0.05-1% of protease, 0.05-1% of dextranase and 0.01-0.1% of vitamin E.
The principle and the advantages of the scheme are as follows:
the rice flour, the chicken, the sweet potato starch and the pea starch can provide nutrient substances such as starch, protein, fat and the like, and are also basic materials for forming the tooth cleaning bone for the pet. The maltodextrin can improve the viscosity of food, increase the solubility of various food materials, play an obvious emulsification role and improve the texture of the product. Glycerol is a sweetener and humectant, making the food smooth and palatable. The vegetable oil can dissolve fat-soluble substances in the food material, and increase bioavailability of the components. Calcium carbonate can increase physical friction and remove dental calculus. The casein phosphopeptide can be combined with calcium to form amorphous calcium, and can clean teeth to form a hard film and fill up cavities on the surface of the teeth. Sodium hexametaphosphate can complex minerals in dental calculus and remove dental calculus. The baking soda has breath freshening effect. Chlorogenic acid has strong bioactivity, and has antioxidant and antibacterial effects. Tea polyphenols and vitamin E have antioxidant effect, and can protect gingiva and teeth. The magnolol extract can inhibit oral anaerobe and facultative anaerobe. The protease can remove protein substances in dental calculus. The glucanase can remove polysaccharide substances in dental calculus.
Further, the pet tooth cleaning bone with the oral cavity cleaning function comprises the following raw materials in percentage by mass: 35.27% of rice flour, 16% of chicken, 16% of sweet potato starch, 12% of pea starch, 8% of maltodextrin, 8% of glycerol, 2% of calcium carbonate, 1% of vegetable oil, 0.5% of casein phosphopeptide, 0.4% of sodium hexametaphosphate, 0.2% of baking soda, 0.2% of chlorogenic acid, 0.1% of tea polyphenol, 0.1% of magnolol extract, 0.1% of protease, 0.1% of glucanase and 0.03% of vitamin E. The above formula is the best mode, and the tooth cleaning effect of the tooth cleaning bone obtained by the formula is the best.
Further, the preparation method of the pet tooth cleaning bone with the oral cavity cleaning function comprises the following steps of:
s1 blending:
mixing rice flour, chicken, sweet potato starch, pea starch and maltodextrin to obtain a first mixed material; mixing calcium carbonate, casein phosphopeptide, sodium hexametaphosphate, sodium bicarbonate, chlorogenic acid, tea polyphenol and magnolol extract to obtain a second mixed material; mixing glycerol, vegetable oil and vitamin E to obtain a third mixed material;
mixing the first mixed material, the second mixed material and the third mixed material to obtain a total mixed material, adding water into the total mixed material, and uniformly stirring to obtain a water-containing total mixed material;
s2 granulation: feeding the total mixed material containing water into a double-screw extruder for granulation to obtain master batches;
s3 forming: processing the master batch by adopting an injection molding method to obtain a molding material: or processing the master batch by adopting an extrusion molding method to obtain a molding material:
s4 baking: baking the formed material, and then spraying protease and dextranase on the surface to obtain a finished product.
By adopting the method, the components with similar properties are mixed, then are mixed totally, and then are subjected to granulation, molding and baking steps and surface spraying steps to obtain the finished product. The method ensures that the materials are uniformly mixed, and the final surface spraying step ensures that the activities of the protease and the dextranase are not influenced by the processing process.
Further, in the S1 ingredient stirring material, the mass of water accounts for 10% -18% of the total mixed material. Adding a proper amount of water to uniformly mix the materials. Too little water is added to not promote the material mixing, too much water is added to dilute the material, and the subsequent master batch preparation process is difficult to carry out.
Further, in S2 granulation, the granulation temperature is 80-140 ℃, the feeding speed is 50-120HZ, and the screw rotation speed is 150-380 HZ. The above parameters ensure the rearrangement of the structure of starch and other substances, and create conditions for tooth cleaning bone formation.
Further, in the molding of S3, when an injection molding method is used, the injection molding temperature is 70-120 ℃, and the injection pressure is 40-100 MPa.
Further, in the molding of S3, when an extrusion molding method is used, the extrusion temperature is 60-120 ℃, the feeding speed is 8-30HZ, and the extrusion parameter is 15-45 HZ.
The injection molding and extrusion molding modes are common pet food processing modes in the prior art, and have simple procedures and easy operation.
Further, in the baking of S4, the baking temperature is 45-70 ℃ and the baking time is 4-15 h. At the temperature, the moisture in the molding material can be fully evaporated, and the water content of the finished product is reduced.
Further, in the baking of S4, the moisture content of the finished product is less than or equal to 16 percent. The water content meets the product delivery requirements and the related pet food standard requirements.

Experimental example: statistical analysis of influence test of dental bone on oral health of adult dog
(1) Experimental methods
The experimental study sample is from adult dogs rescued by a certain waste animal rescue center in Chongqing city, and all dogs are from waste dogs or abandoned dogs in Chongqing city and surrounding areas.
The test period is from 1 month 19 days of 2021 to 6 months 1 days of 2021, and the total period is 135 days. Randomly grouping the test dogs on 19 days in 1 month, and dividing the test dogs into a blank group, a control group and a test group; evaluating the oral cavity condition of the dogs before tooth cleaning only after intravenous anesthesia of all test dogs, then performing tooth cleaning operation by using an ultrasonic tooth cleaning machine, and normally feeding dog food to a blank group after tooth cleaning; in the control group, the dog food is fed normally, and the other companies feed the clean tooth bones on the 15 th day; the test group was fed dog food normally after tooth cleaning and the pet bone prepared in example 1 was fed on day 15. For the control group and the test group, the dog was fed with the bone-cleaning feed 2 hours after each normal feeding, and 25g each time in the morning and afternoon. The chewing time is about 15 min.
The indicators observed in this test were calculus, plaque, gingivitis, pulp exposure, tooth wear and tooth loss, and the breath value was measured before the start of cleaning teeth after anesthesia in order to determine the effect of the product of this test on the breath value of dogs. Thereafter, the oral cavity health status of the dogs was evaluated every month, and the health status of each tooth was scored at 0, 1, 2, and 3 points depending on the severity.
More specifically, the evaluation indexes are:
for dental calculus: score 0 represents: no soft scale and dental calculus; score 1 represents: 1/3% of the small amount of soft calculus or dental calculus occupying the tooth surface; and 2 points represent: calculus, 1/3-2/3 of the tooth surface, and a small amount of subgingival calculus; and 3 points represent: more subgingival calculus is found when calculus exceeds 2/3 on the crown surface. The scorer can give a score one digit after the decimal point according to the severity. For example, the calculus status of a test dog does not exceed 1/3 of the tooth surface, and the scorer will grade the calculus as 0.3, 0.4 or 0.9 according to the severity.
For dental plaque: score 0 represents: the gingival margin is free of bacterial plaque; score 1 represents: the gingival margin area has thin dental plaque on the tooth surface, but the dental plaque can not be seen by visual inspection, and if the tooth surface is scraped by a probe tip, the dental plaque can be seen; and 2 points represent: moderate amounts of plaque are visible at or adjacent to the gingival margin; and 3 points represent: there is a lot of soft scale in the gingival sulcus or in the gingival margin and adjacent surface. The scorer can give a score one digit after the decimal point according to the severity. For example, a test dog may have plaque less than mild but not completely free, and the scorer will score plaque as 0.3, 0.4, or 0.9, depending on severity.
For gingivitis: score 0 represents: without gingivitis; score 1 represents: gingivitis with a slight degree; and 2 points represent: gingivitis with moderate degree; and 3 points represent: with a severe degree of gingivitis. The scorer can give a score one digit after the decimal point according to the severity. For example, a test dog may have less gingivitis than the mild level, but not completely no gingivitis, and the scorer may score gingivitis by severity as 0.3, 0.4, or 0.9.
For pulp exposure: score 0 represents: no pulp exposure; score 1 represents: with a slight degree of pulp exposure; and 2 points represent: pulp exposure with moderate degree; and 3 points represent: with a severe degree of pulp exposure. The scorer can give a score one digit after the decimal point according to the severity. For example, the exposure of pulp of a test dog is less than slight, but not completely absent, and the scorer will grade the exposure of pulp as 0.2, 0.5 or 0.7 depending on the severity.
The breath value measuring method comprises the following steps: after the test animals were anesthetized, they were examined with a mouth gas meter (model: SBM-1C product number: 1C-00174, Beijing Haifuda science and technology Co., Ltd.).
The experimental data were statistically analyzed after preliminary sorting with Excel 2010, and the data were averaged for 10 dogs per group.
(2) Effect of chewing the bones of the teeth cleaner on the deposition of calculus in adult dogs
The test results show that the control group and the test group have a certain retarding effect on the formation of dental calculus in the whole test period, and compared with a blank group, the control group retards the formation of dental calculus by 33% and the test group retards the formation of dental calculus by 39% within 60 days after tooth cleaning; within 100 days after tooth cleaning, compared with a blank group, the formation of dental calculus is slowed down by 11% in a control group, and the formation of dental calculus is slowed down by 19% in a test group; by day 135, calculus deposition was slowed by 16% for the control group and by 23% for the test group relative to the blank group. And the calculus formation slowing effect of the dental cleaning health-care product in the test group is obviously better than that of the control group in comparison with the blank group in the whole test period, after the test is finished, although the calculus deposition condition of each test dog is more serious than that before the dental cleaning, the calculus deposition condition of the test group is closer to the pre-dental cleaning state, and the calculus score is also lowest, and the results are shown in figure 1 and figure 2.
(3) Effect of chewing the bones of the teeth on the formation of dental plaque in adult dogs

(4) Effect of chewing the bones of the teeth cleaner on gingivitis of adult dogs
The test results show that compared with the products of the control group and the test group, the products of the control group and the test group have the effect of relieving the gingivitis of the dogs under test within 100 days after the teeth are cleaned from the beginning of the test; by day 135 of the test, the control group had more gingivitis than the blank, while the test group was still lower. Within 60 days after tooth cleaning, the gingivitis condition of the blank test dog is improved by 42 percent compared with that before tooth cleaning, the gingivitis condition of the control dog is improved by 41 percent, and the gingivitis condition of the test dog is improved by 91 percent; within 100 days after tooth cleaning, the blank group is improved by 56 percent compared with the blank group before tooth cleaning, the control group is improved by 51 percent, and the test group is improved by 91 percent; by day 135 after tooth cleaning, the blank group improved 57%, the control group improved 16%, and the test group improved 73% compared to before tooth cleaning. The test dogs in the test group developed relatively low levels of post-dentrifice gingivitis over time, while the control dogs experienced less gingivitis than but almost similar to pre-dentrifice gingivitis throughout the test period. The test results are shown in FIG. 5.
(5) Effect of application of dental bones to pulp exposure of adult dogs
The test results show that the pulp exposure condition of the test dogs of the test is not present in all the test dogs, the pulp exposure condition of only individual dogs is present and is serious, and certain interference exists in the observation of the pulp exposure condition along with the gradual formation of dental calculus, the pulp exposure grade score of the test group is relatively stable throughout the whole test period and has no aggravation trend although only the individual teeth of the individual dogs are slightly exposed in the time course of the test dogs which do not have pulp exposure condition before, which indicates that the pulp exposure condition of the dental pulp is not aggravated by the dental cleaning bone of the scheme, and the pulp exposure scores of the blank group and the control group are changed in an up-and-down floating manner but are within an acceptable range. The results are shown in FIG. 6.
(6) Effect of application of dental bones on halitosis of adult dogs
The test result shows that compared with the blank group, the breath of the control group and the test dog of the test group is obviously reduced within 60 days after tooth cleaning, the breath values of the control group and the test group are similar, and no obvious difference exists; within 100 days after tooth cleaning, the breath value of a control group is still lower than that of a blank group but is close to that of the control group, and the breath value of a test dog using the tooth cleaning product of the scheme is slightly increased and is not obviously changed compared with 60 days; the test results show that the effect of the tooth cleaning product on reducing the canine halitosis is very obvious and obvious compared with the control group and the blank group.
