Description

Technical Field

[0001] The invention relates to a pet teething stick composition capable of removing dental plaque and a preparation method thereof, belonging to the technical field of pet food. Background Art

[0003] The Chinese patent application number CN201710688478.1 discloses a method for manufacturing a pet chew stick, which uses modified starch, edible glycerin, bone gelatin, and animal bone calcium powder as main raw materials, and includes an inner core and a cowhide layer spirally wound around the inner core. The cowhide used in the chew stick is thick and too tough, which is not friendly to pets. In addition, a large amount of chemicals are introduced into the cowhide during the processing process, which will cause toxic side effects to pets.

[0004] A Chinese patent with patent application number CN201910366035.X discloses a combination of pet tooth-cleaning bones, which is composed of meat meal, potato starch, gluten powder, plant protein powder and glycerin. The ingredients are similar to ordinary dog ​​food and do not have outstanding advantages in cleaning teeth and eliminating bad breath.

[0005] A Chinese patent with patent application number CN202010069791.9 discloses a method for preparing a konjac glucomannan bionic pet teething stick, which uses konjac glucomannan as the main raw material and adds chicken breast powder and duck breast powder. The invention has a single nutritional component, a complicated production process, poor palatability, and the hardness does not achieve the purpose of cleaning teeth.

[0006] The Chinese patent with patent application number CN202011064543.1 discloses a pet teething stick composition containing hyaluronic acid. However, it uses hyaluronic acid fermentation liquid as raw material, which is degraded to obtain hyaluronic acid or its salt of a certain molecular weight, without removing the bacteria. The hyaluronic acid containing the bacteria is mixed with meat powder and directly dried to obtain a teething stick with moderate hardness. Although it is helpful in cleaning teeth and removing bad breath, it involves microbial fermentation and does not remove harmful substances such as bacterial endotoxins, which poses a great safety hazard.

[0007] Cationic dextran is a polycationic derivative of dextran. These derivatives differ from common natural dextran in that they contain multiple amine groups and can be charged in a wide pH range (pH 4-10), so their net charge is much stronger than that of the corresponding natural dextran. Cationic dextran can bind to negatively charged cell membranes through electrostatic interaction, change the permeability of the cell membrane and cause cell death in the bacterial biofilm, thereby quickly removing the bacterial film and bacteria. Dental plaque is usually formed by bacterial biofilm attached to the surface of teeth, so cationic dextran has a very good effect on the removal of dental plaque.

[0008] Pet dogs belong to the order Carnivora, so their digestive system functions are somewhat different from that of omnivorous humans. Currently, more and more pet owners give their pet dogs non-meat food for the purpose of balanced nutrition, and pet food also uses starch as the main ingredient. Therefore, most pet dogs have gastrointestinal problems to a greater or lesser extent. Montmorillonite can increase intestinal motility, thereby enhancing the digestive capacity of the intestine.

[0009] Pets will also actively seek out some wild grasses with anti-inflammatory properties to treat their own discomfort. Alfalfa, turmeric, and purslane are excellent, non-toxic, natural anti-inflammatory plants that are very pet-friendly.

[0010] Compared with cowhide, chicken and duck intestines are easier to obtain and very cheap. The processing process does not introduce any unnecessary chemicals. The long strips are also easier to wrap and process. At the same time, the hardness after air-drying is suitable for pets to chew, and the palatability is better than cowhide.

[0040] Test 1: Short-term cleaning experiment

[0041] Twelve experimental dogs of the same breed with similar tooth cleanliness were selected, and the tooth cleanliness before eating was observed. After feeding the same weight of dog food, they were fed a tooth stick of Example 1-3 or Comparative Example 1-4 respectively. After eating the tooth stick, the remaining food residue was observed again to determine the cleanliness (cleanliness standard reference CN202011064543).

[0042] Results: As shown in Table 1, the molar sticks containing chicken and duck intestines (Examples 1-3 and Comparative Examples 2, 3, 5) have better cleanliness than the molar sticks not containing chicken and duck intestines (Comparative Examples 1, 4).

[0044] Label Cleanliness Example 1 very good Example 2 very good Example 3 very good Comparative Example 1 Poor Comparative Example 2 very good Comparative Example 3 very good Comparative Example 4 Poor Comparative Example 5 very good

[0045] Test 2: Short-term digestion experiment

[0046] Twelve experimental dogs of the same breed with similar tooth cleanliness were selected. After feeding the same amount of dog food within one month, they were fed a tooth stick of Example 1-3 or Comparative Example 1-4. After eating the tooth stick, the feces of the pets after eating the dog food were observed. High-quality tooth sticks should be beneficial to digestion and absorption, and the feces of the pets after eating should be moderate, well-formed and have a normal odor. If the feces of the pet after eating the dog food increase abnormally, are soft and unformed, or are accompanied by a foul odor, it may indicate that the digestibility of the dog food is not high or contains indigestible ingredients.

[0047] Results: As shown in Table 2, the molar sticks containing montmorillonite (Examples 1-3 and Comparative Examples 2-4) are more digestible than the molar sticks not containing montmorillonite (Comparative Examples 1, 4).

[0050] Test 3 Long-term dental plaque experiment

[0051] The experimental dogs in the above-mentioned experimental example 1 were subjected to a dental plaque test before eating the pet molar stick of the present invention: after the experimental dogs drank some drinking water, a sterile soft cotton swab was dipped in a commercially available dental plaque indicator to apply the indicator to three index tooth positions: the upper middle incisor, the upper left middle molar, and the lower right middle molar, respectively. The action of applying the indicator needs to be gentle to avoid scratching. The dark part on the tooth surface 1 minute after applying the indicator is the dental plaque, and a visual oral mirror is used to observe and record the index tooth position, and the Turesky plaque index modified method is used to record the plaque index of the experimental dog's index tooth position as the plaque index before the experiment; after the experimental dogs ate the pet molar stick of the present invention or the comparative example molar stick for one month, the pets were fed drinking water or induced to eat drinking water, and a sterile soft cotton swab was dipped in a commercially available dental plaque indicator to perform the same application of the indicator to the same three index tooth positions. After applying the indicator for 1 minute, a visual oral mirror was used to observe and record the index tooth position, and the Turesky plaque index modified method was used to record the plaque index of the experimental dog's index tooth position as the plaque index after the experiment.

[0052] The recording standards for plaque index are:

[0053] There is no plaque on the tooth surface, and the plaque index is 0;

[0054] There is a continuous thin band of plaque on the cervical area of ​​the tooth, with a width of no more than 1 mm and a plaque index of 2;

[0055] The plaque coverage area of ​​the tooth neck exceeds 1mm but is less than 1 / 3 of the tooth surface, and the plaque index is 3;

[0056] The plaque coverage area is at least 1 / 3 of the tooth surface, but not more than 1 / 2, and the plaque index is 4;

[0057] The plaque coverage area accounts for 2 / 3 or more of the tooth surface, and the plaque index is 5.

[0058] Table 3: Plaque Index Results

[0059]

[0060]

[0061] As can be seen from Table 3, after eating the pet teeth sticks described in Examples 1-3, the experimental dogs had less dental plaque, a low dental plaque index, and a high degree of cleanliness, while after eating the pet teeth sticks described in the comparative example and the teeth sticks not containing cationic dextran polysaccharide, the experimental dogs had more dental plaque, a high dental plaque index, and a low degree of cleanliness, indicating that the pet teeth sticks described in the present invention can effectively remove dental plaque from pet teeth.

[0062] In summary, the present invention has the following advantages: by setting the tooth cleaning stick into two layers, the outer layer is hard and the inner layer is soft, which has a good taste and pets are very interested in chewing. It combines the dual effects of physical teeth grinding of chicken and duck intestines and biological plaque removal of cationic dextran to maintain the oral health of pets. The addition of montmorillonite powder helps to promote the improvement of the digestive ability of pets, and the addition of related anti-inflammatory plant powders helps to improve the immunity of pets and reduce the disease rate of pets.
