JPH05192095A - Soft dog chew and its preparation - Google Patents

Abstract

PURPOSE:To obtain a soft dog chew having softness suiting aged dogs and dogs having weak teeth by heating and pressurizing a hard dog chew prepared by conventional process in a pot and reducing the pressure to expand the chew. CONSTITUTION:Animal skin, preferably raw hide obtained by peeling the outer skin of oxhide or a raw hide layer containing subcutaneous fat layer is cut to proper size, hardened by drying, pressurized under heating in a closed hot pot and expanded by instantaneously releasing the pressure to obtain the objective soft dog chew.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a dog chewing substance called dog chew, which is effective as a dog chew for old dogs and dogs with weak teeth.

[0002]

BACKGROUND OF THE INVENTION Generally known dog chews are formed between the epidermis of cattle or other animals and the subcutaneous fat layer (a part of meat), and are thick and dense composed of connective tissue and adipocytes. Peel the dermis, or rawhide, from the epidermis and apply this to a width of 3
Cut into strips with a length of ~ 5cm and a length of 10 ~ 30cm, and further tie them at both ends to expand them into bones, then dry and harden them in the sun etc. Met. It is also known to use a dye that is harmless to humans and animals for coloring.

[0003]

The conventional hard dog chew described above has both the original chewing effect of promoting saliva secretion by the dog's preference for chewing, and the purpose of training the canine at that time. However, since the dog chew produced by the above method needs to be inserted to an extent suitable for storage, it is rather high in hardness, and if it is given to a puppy immediately after weaning, a sick dog with weak teeth, or an old dog, it will adversely affect the teeth. There was a problem that led to.

[0004]

Means for Solving the Problems The present invention focuses on the fact that the conventional hard dog chew can solve the problem described by imparting flexibility suitable for chewing young dogs and old dogs,
It has been completed as a result of various studies, and is a rawhide layer from which the epidermis has been peeled off from cows and other animal hides, or a rawhide layer from which the subcutaneous fat layer has been peeled off from the rawhide layer (the part that becomes the raw leather of tanned leather). It is said that the conventional hard dog chew, which is obtained by cutting the layer to an appropriate size and drying and hardening, is further heated and pressurized in a rotary closed heating pot, and then rapidly decompressed to expand this under reduced pressure. It is by means of means.

[0005]

[Function] The hard dog chew obtained by the conventional method is expanded under reduced pressure to sponge the inside and soften without changing nutrition and flavor.

[0006]

EXAMPLES The constitution of the present invention will be described in more detail below according to one production method example. A relatively thick fat formed between the epidermis of animal hide, preferably cowhide, and the subcutaneous fat layer (a part of meat). Take out only the cell layer, ie, rawhide,
Cut into strips of 3 cm and 3 to 7 cm in length. Each strip is swelled into bones by tying both ends together, and then dried and cured in the sun.

When an appropriate amount of this hard dog chew is put in a rotary closed heating kettle and heated by a gas burner while slowly rotating the kettle, the internal dog chew is heated to a high temperature and at the same time the internal pressure rises. If the pot lid is opened and the pressure is released all at once when the internal pressure reaches about 10 atm, the dog chew in the pot will expand under reduced pressure and its volume will increase by 3 to 10 times, causing the internal tissue to spondify and become soft. You can get dog chew.

[0008] Generally, rawhide is a raw dermis which is a target of tanned leather, and is formed by relatively thick and dense connective tissue and adipocytes, and the epidermis and subcutaneous fat layer (part of meat) and Is the part that exists between.

Therefore, it is most ideal to use only pure rawhide as a raw material as described in the previous embodiment, but if it is a small amount, the rawhide layer to which the subcutaneous fat layer is attached is used. However, the purpose of the soft dog chew of the present invention can be sufficiently achieved.

As a raw material for the soft dog chew according to the present invention, beef rawe has produced the most preferable result. However, it is not particularly limited to the animal species, and the shape and size of the dog chew are also not limited. Is freely selected depending on the breed of the target animal, and further during the processing step,
It is also intentional to add a coloring agent or a flavoring agent harmless to humans and animals to coloring or flavoring the dog chew.

[0011]

As described above, the soft dog chew of the present invention has the same material and flavor as the conventional hard dog chew, but its main body is soft and has a good texture, and dogs with weak teeth such as young dogs and old dogs. On the other hand, it is a new product having an excellent effect that the original chewing effect of dog chew can be obtained without damaging the teeth.

Claims (3)

[Claims] 1. A material obtained by cutting rawhide peeled from the skin of animal hide, preferably cowhide, into appropriate sizes and drying the rawhide.
A soft dog chew that is heated in a closed container and expanded under reduced pressure. 2. A material obtained by cutting a rawhide layer, preferably a rawhide layer containing a subcutaneous fat layer from which the epidermis of cowhide has been peeled off, into an appropriate size and drying and curing the material, and heating the material in a closed container to expand under reduced pressure. Characteristic soft dog chew. 3. A step of cutting a rawhide, preferably a rawhide containing peeled skin of cowhide, or a rawhide layer containing a subcutaneous fat layer into an appropriate size and drying and curing, and heating and pressurizing this in a closed heating pot. After that, the soft dog chew is made by releasing the pressure all at once and expanding it under reduced pressure.
