Description

[Detailed Description of the Invention] This invention relates to a method for producing a toy diet for blind dogs that is most preferred by dogs, serves as a source of milk protein, and is less likely to become sticky due to dog saliva. .

Conventionally, products that are commercially available as toys and food for blind dogs are:
Mixing powdered or powdered raw cowhide or dried cowhide with an appropriate amount of gelatin and melt-molding it, or mixing 60-95% by weight of milk casein and 40-5% by weight of gelatin and heat-molding it. The method is widely used.

Since all of these products have animal protein as their main ingredient, they match the eating habits of blind dogs and are highly desirable as toys and nutritional supplements. However, most of the cowhide products in particular are manufactured by hand. The shapes and weights are different, and the products are expensive because they are not suitable for mass production.
Furthermore, quality changes are likely to occur due to mold growth, etc.

On the other hand, gelatin products attracted attention as a mechanized manufacturing method, but during the manufacturing process, when drying the gelatin and sugar gel, the remelting temperature of the gel must be below 45°C. , it requires a long drying time of 72 hours or more, and has disadvantages such as slow production speed despite mechanization.Also, when gel-like materials are dried at temperatures close to room temperature, bacteria are likely to breed. In addition, the amount of sugar, which is essential for molding, is as high as 80% by weight, which has the disadvantage of being harmful to blind dogs if they eat it in large quantities.

Furthermore, when a large amount of gelatin is added to milk casein, the gelatin becomes sticky due to the dog's saliva, and as a result, sand, dirt, etc. adhere to it, making it extremely dirty and unclean.

The present invention was made to eliminate the drawbacks of such conventional products, and consists of milk casein powder or granules of 95 to 100% by weight, water, gelatin, or a wetting agent alone or a mixture thereof. 5 to 0% by weight, and then heated at 70 to 320°C, 280 to 1500 to
The present invention provides a method for producing a toy food for blind dogs, which is characterized in that it is molded into a desired shape in step I, and the details thereof will be described below.

Dogs naturally prefer milk casein containing 100% by weight, so it is desirable to maximize the amount of milk casein as long as molding is possible. In order not to reduce the amount of water, it is unavoidable to add a small amount of water, gelatin, or a wetting agent, or a mixture thereof, but the amount of these additions must be 5% by weight or less. .

This is because, if it exceeds 5% by weight, the dog's saliva becomes sticky, and sand, dirt, etc. adhere to it, resulting in significant staining, which is undesirable.

Here, the type of wetting agent is not particularly limited as long as it is non-toxic, but glycerin, propylene glycol, etc. are useful as they are readily available.

In the molding of this invention, heating temperatures higher than 320°C may cause thermal decomposition, and molding is difficult at temperatures lower than 70°C.
Even if molding is possible at high pressures exceeding 80 to
Since injection molding is impossible at a low pressure of /d, the temperature is 7.
It is preferable that the temperature is 0 to 320°C and the pressure is about 80 to 1500/i.

What type of molding machine can you use, as long as the temperature and pressure can be adjusted arbitrarily? can be obtained.

The products obtained by this invention can be produced in large quantities with elaborate taste shapes, bone shapes, etc. that could not be obtained conventionally, the product price is low, and it does not contain any sugar, although it may contain gelatin. Since the amount is very small, there is almost no stickiness due to saliva, etc., and since milk casein is the main ingredient, it can be said to be an excellent food that is rich in nutrition and easy to digest.

Example Glycerin was selected as a wetting agent, and water, gelatin, or a wetting agent in this invention, each alone or a mixture thereof, was added to powdered milk casein at various blending ratios as shown in the table (% indicates the final product). (% by weight) was molded into a rod with a diameter of 30 layers and a length of 150 shoes at 140'C and 200~/i.

When the obtained products were given to dogs, the dogs liked them, and there was almost no stickiness caused by saliva.

It was observed that as the amount of milk casein decreased, the elasticity increased and molding became easier, but the stickiness tended to increase gradually.
