Description

  The present invention relates to a pet food, and more particularly to a pet food having a multilayer structure in which a brown rice-containing material is used as a central core and an animal protein and flour-containing material are coated on the periphery.

  In recent years, the number of pets such as dogs and cats is said to exceed the number of children. And depending on the pet type, age, physique, health condition, breeding environment, etc., various pet foods are available, especially nutritional balance, taste, appearance (shape, size), cost, etc. Various ideas have been made from the viewpoint.

  There are wet type, semi-moist type, dry type, etc. depending on moisture content as pet food, and it consists of core part and outer layer as dry type, changing taste to suit pet's taste, or various nutritional ingredients Pet foods that combine these are known.

  For example, in an animal food comprising a large number of small pieces formed of a nutritious substance, each small piece is substantially coated with an aroma coating made of a savory edible substance, and the coating further comprises a spare. Food for animals to which flavor-added particles made of cooked meat, poultry meat or fish or a mixture thereof are attached (for example, see Patent Document 1), a porous core member adsorbing oil and fat, From the fat intermediate layer covering the core member, the powder layer of the easily denatured component adhering to the outside of the fat intermediate layer, and the outermost layer mainly composed of the polysaccharide adhering to the outside Dry type pet food (see, for example, Patent Document 2) and dry pet food having a crisp texture (eg, Patent Document 2) that includes a granular material inside and is covered with an outer layer. 3) is known That.

  In addition, as pet food using brown rice, at least a pet food containing a group of grains containing whole grains of brown rice that has been powdered after roasting is known (see, for example, Patent Document 4).

  On the other hand, there is no known pet food having a roasted brown rice grain as a central core and an outer shell mainly comprising animal protein and wheat flour that covers the periphery of the central core.

  As raw materials for pet foods, by-products and wastes from various industries are used in addition to those of plants and animals used by humans. In modern society, various health-oriented foods are sold and used due to lack of exercise and the like, and pet foods have the same tendency. It is not uncommon for humans to eat brown rice, which is richer in vitamins, minerals, and dietary fiber than white rice, but it has been devised in terms of digestibility and preference for its use. In the case of using brown rice as a raw material also in pet food, there are the same problems as described above. Traditionally, brown rice has been used as a pet food. However, pet food using powdered brown rice is manufactured by kneading and molding with other powder raw materials, and the appearance and form are not new. An object of the present invention is to provide a pet food that has a high digestibility, is rich in well-balanced nutritional components and vitamins, has improved palatability, and has a favorable texture and appearance.

Looking specifically at the ingredients contained in brown rice, the germ part contains crude protein, fat, vitamins A, B1, B2, B6, B12, E, pantothenic acid, folic acid, various minerals, Niacin, which is said to have an inhibitory effect on cancer, is included.
In the pet food, the present inventors have made extensive studies in order to make use of the components contained in brown rice, and in combination with other proteins, wheat flour, etc., without reducing the palatability, and can be easily manufactured. In the past, brown rice was pulverized and used, but the powder process was omitted, the brown rice was roasted, and the roasted brown rice was used as the core, and the periphery of this core was externally containing animal protein and flour. It has been found that a pet food in which various flavor components are formed in layers on the outer shell can be obtained by forming the shell, and the present invention has been completed.

  That is, the present invention includes (1) a pet food comprising a central core containing brown rice, and an outer shell that covers the periphery of the central core and is composed mainly of animal protein and flour, and (2) The brown rice is roasted brown rice, the pet food according to (1) above, and (3) the central core is 5 to 10% by mass or (1) or The pet food according to (2) or (4) the pet food according to any one of (1) to (3) above, wherein the outer shell is formed in a multilayer using a binder.

  According to the present invention, by using brown rice roasted in the core, it is highly digestible, facilitates the intake of various vitamins, pantothenic acid, folic acid, various minerals, and contains proteins, carbohydrates, and taste ingredients in the outer shell. By using the outer shell as a multi-flavored multilayer, it is possible to obtain a pet food that is generally balanced and favored by pets.

  The pet food of the present invention is not particularly limited as long as it has a central core containing brown rice and an outer shell mainly comprising animal protein and flour, covering the periphery of the central core. The central core (core) is not particularly limited as long as it contains brown rice, and may contain arbitrary components as appropriate in addition to brown rice alone. Examples of such optional components include wheat grains, nuts, dried fruits, corn, soybeans and the like.

  Moreover, as brown rice contained in central core, the gelatinized brown rice grain | grains, such as roasting, cooking rice, and steaming, are preferable, and the brown rice which carried out the roasting process is more preferable. The roasting treatment increases the scent of brown rice, improves digestion, improves surface processability, and improves the palatability of pets. Thus, it is preferable to use approximately 1 roasted brown rice grain for the central core. In the roasting treatment of brown rice, for example, the brown rice is immersed in water, dried at 120 to 140 ° C. for 30 to 50 minutes, and then roasted to the extent that the color tone changes to the whole at 250 to 350 ° C. (not burnt).

  The outer shell covering the periphery of the central core is mainly composed of animal protein and wheat flour. Here, “main component” means that the amount of the components (animal protein and wheat flour) is 50% by mass or more. , Preferably 80% by mass or more, more preferably 90% by mass or more. Such an outer shell is usually coated in a layer form using a binder, but it is a multilayer, preferably 3-5, with a central core / binder 1 / outer shell 1 / binder 2 / outer shell 2 / binder 3 / outer shell 3. It is preferable to form it in a layer for reasons such as a plurality of types of flavor / flavoring, improved texture such as crispness, surface gloss, and improved physical strength. As the binder, in addition to sugars such as sugar, starch syrup, honey, brown sugar, and maple syrup, an oil and fat composition that exhibits a molten state at a temperature near body temperature and a solid state at a temperature near normal temperature can be used.

  Examples of the animal protein include meat powder made from beef, pork, chicken, lamb, horse meat and the like, fish powder such as bonito powder, chidai, and shellfish powder such as scallops. Moreover, as wheat flour, a weak flour and a medium flour can be mentioned suitably. Animal protein and flour can be mixed at a ratio (mass ratio) of 5:95 to 50:50, preferably 10:90 to 30:70, more preferably 15:85 to 25:75. In addition to animal protein and wheat flour as main ingredients, as optional ingredients, powdered red plum, rye flour, mica flour, barley flour, corn flour, wheat germ, rice bran oil cake, rice bran, seaweed, fish oil, olive oil, sesame, soybean Oil and fat, beef tallow, lard, soy and other animal and vegetable oils, bran and other dietary fibers, vegetable-derived ingredients, molasses, sugar, lactose, oligosaccharides and other sugars, vitamins, minerals and other micronutrients, polyhydric alcohol, baking soda, Bone powder, water, etc. can be blended. Moreover, it is preferable to attach various palatability substances (spices) selected according to the type, age, and season of cats, dogs, etc., to the outermost surface of the outer shell.

  The central core is desirably 3 to 30% by mass of the pet food, preferably 5 to 10% by mass, and more preferably 7 to 9% by mass in terms of flavor / taste and texture. The size (particle size) of the pet food of the present invention is not particularly limited, but can be 5 to 15 mm, preferably 7 to 11 mm.

  EXAMPLES Hereinafter, although an Example demonstrates this invention more concretely, the technical scope of this invention is not limited to these illustrations. The blending ratio is mass%, but is simply represented by “%”.

(Roasted brown rice production method)
Rice with rice husk is polished to obtain brown rice. 4 kg of brown rice was immersed in water for 30 to 90 minutes and dried at 130 ° C. for 40 minutes. After drying, brown rice is fed to a roasting machine and roasted at 300 ° C, and when the smell of fragrance that does not burn is observed while observing the color of brown rice, heating is stopped, cooled to 50 ° C, and further brought to room temperature. Was allowed to cool. To obtain constant granules, they were sieved.

(Method for producing pet food having roasted brown rice core)
Roasted, put 1.5 kg of brown rice with a certain particle size into a pan (pan) equipped with a heating device, and stir while sprinkling 800 g of sugar water (binder solution 50 ° C, 60% concentration, the same applies below) Sugar was attached to the surface of roasted brown rice. Next, 2 kg of wheat flour (weak flour) was stirred and sprinkled to adhere the wheat flour to the surface of the roasted brown rice. The surface of the wheat flour was again sprinkled with 800 g of sugar water and stirred to adhere the sugar water. Next, 2 kg of mixed powder (60% wheat flour, 10% cold plum powder, 30% scallop) was sprinkled on the surface. Furthermore, it stirred while sprinkling 800g of sugar water, and sugar water was made to adhere. Next, 3 kg of bonito flour was stirred and sprinkled on the surface. Next, 800 g of sugar water was sprinkled and stirred to attach sugar water, and then 4 kg of mixed powder (wheat flour 50%, taste substance 50%) was attached to the surface. Next, after sieving to remove unadhered powder, it was fired at 180 ° C. for 15 minutes. After baking, the mixture was allowed to cool to room temperature, and after cooling, the granules were screened through a fixed sieve to produce 14.5 kg of a four-layered 6.7 × 8.6 mm oval pet food for cats.
