Description

Semi-Dried Feed for Companion Animal and Method

The present invention relates to a method for manufacturing semi-dry food for companion animals, and more particularly, when raw meat is ground to a nano level, by adding a protein binder, the raw meat content can be increased up to 90%, and the moisture content can be increased to an intermediate level of 20 to 35%. It relates to a method for manufacturing semi-dry food for companion animals with excellent preservation and chewability by drying to moisture level.

As the most frequently raised companion animal in the household, dogs and cats prefer food containing raw meat. In particular, young pets with soft teeth like semi-dry food that is soft to eat.

Moisture content control and packaging technology are very important in developing semi-dry feed. Intermediate moisture foods (IMF; ), the texture is good and the preservation is good.

As a prior patent technology for this intermediate moisture-containing feed manufacturing method, Korean Patent Publication No. 10-2001-0101048 (Jan. 24, 2001) discloses a method for enhancing the palatability of pet food in a semi-dry state, but palatability The enhancer is a feed preparation method of spraying about 01 to 10% by weight of tetrasodium pyrophosphate in a cat pet food product using the final labor by-product.

However, raw granulated meat contains more than 70% moisture, and it is difficult to mold due to the low mutual binding power. There is a problem in that it is difficult to increase the maximum content of raw meat by more than 40%.

While the present inventors have been working from various angles to solve this problem, raw meat is grinded to a nano level and moisture and binding power can be controlled by adding a protein binder, so that the content of raw meat can be increased up to 90% while being soft and semi-dry to eat. We succeeded in developing pet food with high preference by developing feed manufacturing technology.

Nanotechnology can be carried out in a dispersion emulsifier having an impeller structure that can continuously feed raw meat into pieces. More preferably, the raw material particles are nano-sized by passing through a nano-emulsification grinder equipped with an impeller structure equipped with a cooling and heating system that can circulate cold and hot water to the outside, characterized in that the raw material particles are pulverized to a size of 10 ^-2 to 10 ^-3 μm. It may be a method for manufacturing semi-dry food for companion animals.

Most preferably, it can be carried out in a dispersion emulsifier having a rotor-rotor type impeller structure equipped with a cooling and heating system that can prevent deterioration due to excessive increase in the temperature of raw meat during the nano-pulverization process.

At this time, if raw meat is pulverized into nano particles, it is possible to increase palatability according to the enhancement of rich flavor, increase pepsin digestibility, reduce the amount of defecation and stool odor, and prevent allergies by reducing the protein molecular weight.

At this time, the nano-izing step of step (S2) is passed through a nano-emulsification grinder equipped with a rotor-rotor impeller structure equipped with a cooling system, and the nano-ization of raw material particles is 10 ^-2 to 10 ^-3 ㎛ Companion animal semi-dry type It may be a feed manufacturing method.

The nanoized mixed raw material is extruded in an extruder at 100 ° C, and then the extruded mixture is passed through a cooling transport route and cooled to 20 ~ 30 ° C to increase the binding force, cut into a certain shape, and reduce the moisture content to 20 ~ It is packaged in a semi-dry state of 35%. In this semi-dry state, chewability is good and storage stability is improved.

In addition, according to another embodiment of the present invention, the protein binder in step (S1) is 30% soy protein isolate, 20% egg protein powder, 20% alginate, It provides a method for manufacturing semi-dry food for companion animals, characterized in that it contains 5% calcium phosphate, 5% mixed phosphate, 10% potato starch, 5% guar gum, and 5% transglutaminase.

In addition, step (S1) provides a method for producing semi-dry food for companion animals, in which a raw material containing 90% or more of raw meat and 1 to 5% by weight of a protein binder are mixed.

In the protein binder composition, calcium phosphate and metaphosphate, polyphosphate, pyrophosphate, etc. are mixed and used as the mixed phosphate as the phosphate, which is used to increase the water holding capacity of the protein and increase the binding property.

As emulsification aids, soy protein and egg protein improve the emulsification power of the product and are used as alternative proteins when protein is insufficient. The soy protein used in the present invention and egg white powder, which is an egg protein, has a very high protein content, and the egg yolk powder contains protein and lecithin, so it is used as an effective emulsifier.

Alginate gum acts as a thickening and tissue strengthening agent, which doubles its ability to retain water by 20-30 times, and fixes the meat gel to improve the tissue so that it is sliced neatly.

In addition, CMC (carboxy methyl cellulose:) is used as a carbohydrate. For CMC, carboxymethylated cellulose containing more than 40% of hydroxyl groups is well soluble in cold water and becomes a stable colloidal solution with high viscosity. This CMC is used as a thickener or emulsion stabilizer to increase the viscosity, absorbs moisture without being absorbed in the intestines and plays an important role in molding, and is used in less than 2% of the total.

As for starch, potato starch absorbs water, but is not used to extract protein, but only because of the weight effect, so the binding force is weak when forming emulsifying power. The gelatinization temperature is about 53-55˚C.

As calcium oxide, eggshell calcium dissolves the protein on the meat surface and creates conditions for phosphate and protein to adhere well.

Transglutaminase plays an important role in the protein binding technology of real meat of the present invention. It is an enzyme that promotes cross-linking polymerization between protein molecules, and cross-linking between glutamine and lysine residues of protein molecules It is an enzyme that promotes binding and polymerization.
