A method in which cereals and milk casein are used in combination. (JP-A-8-266231) A method using milk casein in combination with an appropriate amount of gelatin. (JP-B-57-39616) A method in which bone meal and milk casein are used in combination. (Japanese Patent Publication No. 61-52654) A method in which raw bone powder and milk casein are used in combination. (Japanese Patent Publication No. 7-16363) and the like are known.

[0093]

However, melt injection molded products mainly containing gelatin and milk casein are 130 to 2 parts.
Heating at 00 ° C. was required, and there was a point that the fragrance added for flavoring and the preferred fragrance derived from the raw material were lost.

When gelatin was contained, the surface of the molded product was sticky when dog saliva adhered or got wet with water, and it could not be given to pets in a clean state. .

Mix easily oxidizable substances such as unsaturated fatty acids (eicosapentaeiic acid, docosahexaenoic acid, etc.) and substances which are easily decomposed by heat such as vitamins.
There is a difficulty in manufacturing using an injection molding machine at a low temperature of 0 ° C. or lower.

When milk casein was used, it had a high nutritional value and was not suitable for pets such as dogs and cats, which tend to be obese.

Further, those molded in a required shape at a low temperature (20 to 50 ° C.) using an injection molding machine had a point that they easily rot.

In addition, in terms of industrial productivity, gelatin and milk casein have high raw material prices, and in the pet animal feed market which requires inexpensive raw materials, the product price is high.

Means for Solving the Problems To solve the above problems, the present invention relates to a modified starch in a β-form or an α-form, and glycerin, propylene glycol, starch syrup, or reducing sugar in water. By combining the above as the main component, a method for solving the problem was found, and the present invention was completed.

As a method of mixing the raw materials involved in the present invention, any method machine may be used as long as it can be uniformly mixed using a kneader, a mixer or the like.

In the production method of the present invention, after the raw materials are uniformly mixed, they may be kneaded and rolled, cut out with a specific metal frame, or may be produced using an injection molding machine mainly used for resin molding. good. There is no problem in selecting a machine for manufacturing using any type of machine. However, it is desirable to use an injection molding machine in order to industrially produce a large quantity of uniform products.

The production conditions when using an injection molding machine vary depending on the physical properties desired for a product. For example, if it is desired to produce a hard and less elastic material, a high temperature (for example, 130 ° C.) high pressure (for example, 1500 kg / c)
m ² ), the desired product can be obtained. Conversely, if it is desired to produce a soft and highly elastic product, the desired product can be obtained by injection molding at a low pressure (for example, 30 kg / cm ² ). By changing the injection molding conditions, the mixing ratio of the raw materials, and the like, the desired physical properties can be freely formed.

The modified starch in the beta state used in the present invention is a starch which does not dissolve when mixed with water and shows a precipitated state, and becomes a paste by heating at about 60 ° C. or more.
It is a starch with physical properties that change to a pregelatinized state.

The chemically modified starch in the pregelatinized state is obtained by converting the pregelatinized modified starch into the pregelatinized state by heating, is easily dissolved when mixed with water, and can be pasteurized without heating. It becomes something.

The types of modified starch used in the present invention include cross-linked starch (cross-linked by phosphoric acid or adipic acid treatment, etc.), cross-linked starch, etherified starch (sub-etherified with a chemical such as hydroxypropyl), and the like. Esterified starch (esterified with a chemical such as acetic acid), oxidized starch (oxidized with a chemical such as sodium hypochlorite), acid-decomposed starch (acid-degraded with a chemical such as sodium hypochlorite) ). Depending on the processing method, it can be made in either the α-form or the β-form.

The starch used as the raw material of the modified starch used here is constarch, waxy corn starch, rice starch, wheat starch, tapioca starch, potato starch, sweet potato starch,
The type of starch such as sago palm starch does not matter.

The difference between modified starch and ordinary starch is that, for example, those made with constarch lose elasticity over time and become easily broken, while those made with modified starch do not lose elasticity forever. .

The modified starch in the beta state or the alpha state and water are added to
When manufactured using glycerin, propylene glycol, etc., despite not using gelatin,
Products with elasticity as if using gelatin can be manufactured.

[0202] In addition, since modified starches are less expensive than gelatin and milk casein, when manufactured, they can be produced at low prices suitable for the pet animal feed field market.

[0220] In addition, it was found that the product which had been injection-molded using only modified starch and water lost decay and elasticity when stored for a long time. Similarly, using casein at low temperatures (20
(° C.), the decay phenomenon was also observed in the products injection-molded.

However, a product obtained by injection molding using glycerin, propylene glycol, and the like in modified starch and water, even if produced at a low temperature (20 to 50 ° C.), did not show decay after long-term storage.

When only modified starch, glycerin and propylene glycol were used and no water was added,
The performance of the modified starch could not be exhibited, and when stored for a long time, the elasticity was significantly reduced.

By adding glycerin and propylene glycol, the moisturizing property and the preservative effect can be improved, so that it is not necessary to raise the temperature during injection molding to sterilize the raw materials. ) Can be manufactured.

When gelatin is used, the temperature must be raised to a high temperature (for example, 100 ° C.) in order to melt the gelatin.

In the present invention, the use of a modified starch in the pregelatinized state and propylene glycol, glycerin, or the like eliminates the need for heating and enables production at a low temperature (20 ° C. or lower).
Therefore, it has become possible to easily mix substances that are easily decomposed by heating, such as vitamins and unsaturated fatty acids.
Since heating is not applied, the residual ratio when a fragrance or the like is added is high, and the deterioration of the flavor of the raw material is reduced.

The components of the present invention are chemically modified starch, water and glycerin, etc., and are used as diets for pet animals with obesity tendencies, which have recently become a problem due to their major starch quality. It is possible.

For the purpose of dieting, calories can be suppressed by blending dietary fiber (cellulose powder, microcrystalline cellulose, water-soluble dietary fiber, etc.) in an appropriate amount. Ingestion of dietary fiber also increases the amount of feces in pets and helps to eliminate constipation.

The compounding ratio of the modified starch in the present invention is about 3 to 70% by weight. This is because if the compounding ratio of the modified starch is less than 3% by weight, the elasticity after long-term storage is extremely reduced, and the product itself becomes brittle. When the content is 70% by weight or more, there is less room for water, glycerin, propylene glycol, and the like necessary for production. Preferably, it is 5 to 50% by weight.

The mixing ratio of water is about 3 to 30% by weight. When the mixing ratio of water is less than 3% by weight, it becomes difficult to dissolve or swell the modified starch in the α-form or the β-form, and it is difficult to extract the characteristics of the modified starch even after molding. . Conversely, if it exceeds 30% by weight, stickiness occurs during molding and productivity is significantly impaired. In addition, when the water content is large, it becomes liable to rot when stored for a long period of time, which is a problem. Preferably,
5 to 15% by weight.

When a product is produced by adding sub-materials such as chicken meat and fish meat, the amount of water contained in the sub-materials affects the molding conditions. Just decide.

The mixing ratio of glycerin and propylene glycol is about 3 to 30% by weight. If the content is less than 3% by weight, the elasticity is reduced when stored for a long time after injection molding. On the other hand, when the content exceeds 30% by weight, stickiness occurs at the time of injection molding, which impairs productivity and is not preferable in terms of texture. Preferably, it is 5 to 25% by weight.

The mixing ratio of reducing sugar and starch syrup is about 3 to 30.
% By weight. If the amount is less than 3% by weight, the product cannot be given moisture retention when stored for a long time.
On the other hand, when the content exceeds 30% by weight, stickiness occurs at the time of molding and productivity is remarkably impaired. Preferably,
5 to 15% by weight.

Incidentally, other auxiliary materials may be appropriately added as long as the original object of the present invention is not hindered. As such auxiliary materials, meat such as raw chicken, raw meat, raw fish, plants such as raw vegetables, grains, beans, etc., minerals such as shell calcium, beef bone meal, etc., vitamin C, vitamin A, And unsaturated fatty acids such as docosahexaenoic acid. The mixing ratio of the above-mentioned auxiliary materials can be appropriately changed according to the purpose of the product.

Conditions for molding using an injection molding machine are as follows: temperature: about 1 to 130 ° C., pressure: 30 to 1500 k
Injection molding is performed under the condition of g / cm ² . In this case, 130
If the temperature exceeds 100 ° C., the raw materials are undesirably burnt. When manufactured by cooling to a low temperature of 1 ° C or less,
Moisture, which is the main raw material, may freeze, resulting in poor productivity. Hereinafter, the effects of the present invention will be described in detail with reference to examples, but this is merely an example and the present invention is not limited at all.
