Abstract

PURPOSE:To obtain a pet food having improved palatability to a pet animal as well as fluidity and preservability by adsorbing a palatable liquid substance for pet food to SiO2. CONSTITUTION:A powdery palatable substance for pet food is produced by adsorbing 20-70wt.% of a palatable liquid substance for pet having a water content of 50-75% (e.g. by-product of broiler-processing plant) and about 15wt.% of table salt to SiO2. The obtained palatable substance is added to a pet food at an arbitrary stage during the pet food preparation process to obtain a pet food.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a powdered palatability substance for pet food and a method for producing a pet food using the same.

[Conventional technology]

Liquid palatability substances for pet food are manufactured by autolyzing, enzymatically or acidically decomposed by-products of poultry, livestock, fish and shellfish, but these palatability substances cannot be powdered. It is used in the production of pet food either in its liquid form, by spray-drying, or by adsorbing it on defatted rice bran or wheat bran.

However, because these liquid palatability substances have a viscosity, they are difficult to handle as they are, and have the disadvantage of being easily perishable in terms of storage stability. or it is difficult to mix uniformly.

On the other hand, when using these liquid palatability substances by adsorbing them on defatted rice bran or wheat bran, there is a drawback that a large amount of liquid palatability substances cannot be adsorbed and only products with inferior palatability are obtained. In addition, when powdered using the spray drying method, it may form lumps during storage, absorb moisture and adhere to transport equipment, and deteriorate due to the heat received during the processing process, so it is manufactured at the same concentration as the liquid version. Comparing the preferences of pet animals for the following pet foods:
Currently, the scope of use of these palatability substances for pet food is narrowed due to drawbacks such as poor palatability.

[Problem to be solved by the invention]

An object of the present invention is to avoid the above-mentioned difficulties of liquid palatability substances for pet food, and to make it possible to easily and quantitatively add and mix palatability substances to pet foods while maintaining palatability. Our goal is to provide the following.

[Means to solve the problem]

In order to solve the above problems, the present inventors conducted various research on liquid palatability substances for pet food, and found that when silicon dioxide is adsorbed with liquid palatability substances and used in the production of pet food, the palatability The present invention has been completed based on the discovery that the powder can maintain the following properties and that it can be easily scooped out because it is a fluid powder.

That is, the present invention provides a powdered palatability substance for pet food in which a liquid palatability substance for pet food is adsorbed on silicon dioxide, and a powdered palatability substance for pet food in which a liquid palatability substance for pent food is adsorbed on silicon dioxide. This is a pet food manufacturing method characterized by adding this powdered material at any step of pet food manufacturing.

The silicon dioxide used in the present invention is hydrated amorphous silicon oxide, which is called white carbon in boat fishing, or light anhydrous silicic acid. Liquid palatability substances for pet food include broiler processing by-products, egg-laying waste chicken, shoulder meat of livestock such as cows and pigs, or internal organ by-products such as liver, shoulder meat of tuna and bonito, or internal organ by-products such as liver. By-products such as meat or internal organs of seafood such as shrimp, krill, and squid are used after being subjected to autolysis, enzymatic or acid decomposition treatment. These liquid palatability substances generally have a water content of 50-75%.

In the present invention, when a liquid palatability substance for pet food is adsorbed to silicon dioxide, when the water content of the liquid palatability substance for pet food is converted to 50 to 75%, if the amount to be adsorbed is small, the palatability substance is The solid content is small and easily scatters, and if a large amount is adsorbed, the moisture content of the powder becomes high, causing problems in terms of storage stability and flowability, so it is about 20 to 70%. It is desirable to adsorb it in a similar manner.

When a liquid palatability substance for pet food is adsorbed onto silicon dioxide in this way, the palatability substance becomes a fluid powder, but the water contained in the liquid palatability substance transfers as is, improving its shelf life. Therefore, it is desirable to add substances having a preservative effect such as common salt, sugars, and propionic acid. At this time, when adding salt, care should be taken to ensure that the salt content in the final pet food product is not too high, and it should be added to the level that the powdered palatability substance contains approximately 15% salt. desirable.

Examples of auxiliary materials for the adsorption base material include starch, cellulose,
Auxiliary materials such as cellulose and phosphates improve the fluidity of the powdered palatability substance for bed food.

As a method for adsorbing the liquid palatable substance for pet food onto silicon dioxide, any method that can uniformly adsorb this liquid palatable substance may be used. For example, ribbon mixer, Nauta mixer,
While stirring the silicon dioxide using a high-speed stirring mixer or the like, a liquid palatability substance for pet food can be sequentially added and adsorbed to form a powder. If the viscosity of the liquid palatability substance for pet food is high, it is desirable to add it through a nozzle while heating it.

The powdered palatability substance for pet food obtained as described above can be added at an appropriate time during the manufacturing process when manufacturing pet food.

The method of addition is arbitrary, and it may be added alone during the manufacturing process, or may be added after being mixed with other raw materials in advance, or may be further extruded and coated after molding. The amount of the powdered palatability substance to be added may be adjusted according to the usual desired amount of the palatability substance to be added to each product such as pet food, for example, tong food, cat food, and the like.

The pet food to which the palatability substance for veterinary food of the present invention can be applied is not particularly limited by the type of animal, growth level, etc. Then, it will be more effective.
