Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to pet foods such as dogs and cats, and more particularly to pet foods containing a surfactant such as glycerin fatty acid ester.

[0002]

2. Description of the Related Art In recent years, the popularization of pet foods for dogs and cats has been remarkable. However, with the spread of pet food, obesity of the pet itself and various diseases associated with obesity are becoming a problem, and from the practitioner veterinarian it is not a post-treatment such as treatment, but a pet food that is not prone to radical obesity There is a strong desire for development. On the other hand, pet food for obesity prevention or obesity improvement has already been sold in accordance with such demands.

The method employed is, for example, a method for increasing the fiber content by adding a large amount of alfalfa as a dietary fiber source, peanut pod meal, or various meals, or reducing the addition of fats and oils. For example, a method of selecting a raw material with a low crude fat content and reducing the amount of fat derived from the raw material as much as possible to lower the energy.

However, although such pet food can temporarily lose weight or stall the increase in weight, when it is fed in the medium to long term, the intake amount increases due to low energy, and conversely. As a result of extreme poor palatability, the owner loses his / her pet's petition and interrupts the salary, often failing to achieve the intended purpose.

[0005] In addition, it is substantially the same as feeding a carnivore such as dogs and cats which feeds to herbivores, and since a large amount of indigestibles is fed to the pet, it causes the digestive tract such as the large intestine to enlarge. It has also become a serious problem from the viewpoint of health and management, because the amount of excrement of feces has increased remarkably.

[0006] In pet foods, if high calorie and high preference foods are taken, pets easily cause overeating and easily fall into obesity, and so far no effective solution has been made so far.

[0007]

From such a situation,
At present, there is a demand for the development of pet foods that can prevent or improve obesity while pets are willing to eat and satisfy their owners. The present invention does not provide pet foods having these effects. It is what

[0008]

Means for Solving the Problems In order to develop the above-mentioned pet food, the present invention has conducted various researches on the improvement of pet food. As a result, a surfactant such as glycerin fatty acid ester is added to the pet food raw material as a blending raw material. However, the present invention has been completed by discovering that the extruder treatment can happily eat pet dogs and cats and prevent or improve obesity of pets.

That is, according to the present invention, one or more kinds selected from glycerin fatty acid ester, propylene glycol fatty acid ester, sorbitan fatty acid ester, sucrose fatty acid ester, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene glycerin fatty acid ester as a pet food raw material. 0.3-10% by weight of surfactant
A pet food characterized by being extruded after being contained, the purpose of which is to prevent the onset of obesity peculiar to pets or to reduce the incidence or improve the obesity of pets that have developed. It is to provide pet food that can be measured.

The surfactant used in the present invention is represented by, for example, glycerin fatty acid ester. In glycerin fatty acid ester, 1 mol of fatty acid such as stearic acid and oleic acid is ester-bonded with 1 mol of glycerin. .

Further, instead of glycerin fatty acid monoester, propylene glycol fatty acid ester, sorbitan fatty acid ester, sucrose fatty acid ester, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene glycerin fatty acid ester and the like can be used in the same manner. One or more selected surfactants may be used in any suitable combination.

The pet food of the present invention is modified by mixing a raw material for various pet foods with a surfactant such as glycerin fatty acid ester and then applying heat processing by an extruder. Is mixed with flour, corn and other grains and starches only, and then modified by an extruder,
A method in which a raw material other than grains or starch is added to the modified raw material and the extruder is heat-treated for application to ordinary pet food may be used.

Further, as the starchy raw material, in addition to the usual raw materials, a raw material having a high amylose content, such as high amylose corn starch, is also suitable as this raw material.

Examples of pet food raw materials for incorporating a surfactant such as glycerin fatty acid ester include cereals such as corn, mylo and wheat; fish meal, meat meal, meat meal, meat bone meal, and other ingredients such as wheat flour and corn. Gluten meal, yeast, wheat germ, rice bran oil meal, rice bran, soybean meal meal, bran, corn gluten feed, beef tallow, lard, soybean oil and vitamins and minerals as micronutrients, etc., which can be appropriately selected and used. it can.

As a means for incorporating a surfactant such as glycerin fatty acid ester into a feed ingredient, it may be incorporated at an appropriate time during the pet food manufacturing process. For example, the ingredient may be incorporated at the same time as the other pet food ingredients. You may
Alternatively, it may be added directly in the extruder.

As for the mixing ratio of the surfactant such as glycerin fatty acid ester mixed in the pet food raw material, if the mixing ratio is too small, the mixing effect cannot be obtained, and if it is too large, not only the nutritional balance of the entire pet food is disturbed, Since pets may have diarrhea or loose stools, or it may not be sufficiently swelled by the extruder treatment, it is desirable to mix the feed in the range of 0.3 to 10%, particularly preferably 0.5 to 5%. It is a range.

By subjecting the pet food of the present invention to an extruder treatment, the starches and the like in the pet food raw material are modified with a surfactant such as glycerin fatty acid ester to prevent the occurrence of obesity peculiar to pets or the incidence thereof. However, conditions such as humidity adjustment, temperature, pressure, etc. in the extruder treatment should be appropriately selected as long as the starches are alpha-converted. You can

As for the extruder treatment, a single-screw extruder and a double-screw extruder can be used as long as a desired pet food can be obtained.

[0019]

Example 1 The raw materials having the compositions shown in Table 1 were crushed and mixed, then subjected to high temperature and high pressure treatment with a uniaxial extruder, extruded from a die and cut with a cutter, and then dried by heating with a drier. After molding, pet pet foods for dogs A, B, C, D, E, and F which were formed into a disk-shaped expanded pellet having a diameter of 10 mm were obtained as a control pet food.

[0020]

[Table 1]

Next, 16 obese beagle dogs were prepared,
Each was housed in a single cage. Each of these dogs was used as two dogs, and control groups A to G were provided in 8 groups and 16 cages in total. The pet food for dogs produced as described above was fed ad libitum so as to correspond to each of the plots, and the pet foods were bred for 2 months and examined for changes in body weight and feed intake. The results are shown in Table 2. Note that ()
The inside shows the ratio when the weight at the start is 100.

[0022]

[Table 2]

Next, using the same dog, 40 per metabolic body weight
Restricted feeding was performed in which each g was fed. The environmental conditions of the breeding room were 22 ± 2 ° C. and RH60 ± 10%. The results are shown in Table 3. In addition, the inside of () shows the ratio when the weight at the start is set to 100 similarly to the above.

[0024]

[Table 3]

The pet food for dogs of the present invention was found to be effective in improving obesity in dogs. In particular, the effect was remarkable when combined with restricted feeding.

[0026]

EFFECTS OF THE INVENTION The pet food of the present invention is a pet food of solid or soft type such as expanded pellets, which is obtained by modifying the starch in the raw material of pet food with a surfactant such as glycerin fatty acid ester by the extruder treatment. In that case, there is an effect of improving or preventing obesity.

This is expected to have an effect of preventing or improving cardiovascular heart disease caused by obesity in pets. Such an effect is expected in pet foods containing a large amount of conventional fibers. This was not possible with high-fiber pet foods containing only large amounts of raw materials or low-energy pet foods with reduced fat content. Also, compared to high fiber pet food and low energy pet food, pets are more willing to eat.
