Abstract

PURPOSE:To obtain dried pet food or feed capable of preserving for a long period of time and exhibiting an excellent biting by drying dough prepared from mid-gut gland of cephalopod with a microwave dielectric heating. CONSTITUTION:Mid-gut gland of cephalopod such as a cuttlefish or an octopus and gill, ovarium, skin or other secondary product, as desired, is mashed and added and dispersed into various raw materials such as fish meat, animal meat or others, then free water is almost removed to obtain dough adjusted to a quasi-combined water region. Next, said dough is subjected to a microwave dielectric heating under normal pressure to dry to a combined water region.

Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention involves adding midgut glands, which are by-products of cephalopods, to various raw materials to make dough, which is then dried by microwave dielectric heating. It relates to pet food or feed.

The dry pet food containing cephalopod midgut glands of the present invention is an excellent pet food or feed that dogs and cats like to eat.

(Conventional technology and problems) The midgut gland is a part of the internal organs of cephalopods such as squid and octopus, which is called the liver, liver, or uro.The only resources available for its use are collecting cod liver oil and salted fish. Most of it was discarded unless it was used for enzymatic decomposition or dried and used as fertilizer.

However, these contain nutritive components that are superior to those of the edible portion, as well as components that are palatable to dogs and cats, and their advanced utilization has been a major challenge.

(Means for Solving the Problems) As a result of various researches aimed at effectively utilizing the midgut glands of cephalopods, the present inventor discovered that the midgut glands, and if necessary, the whole, ovary, skin, and other by-products. If you grind it, add it to various raw materials and disperse it, make a dough with a moisture band in the semi-bound water region, and heat it by microwave induction.

It was discovered that extremely excellent pet food and feed could be obtained, and the present invention was completed.

The present invention relates to dry pet food or food containing cephalopod midgut glands.

In addition, the present invention prepares a dough containing crushed cephalopod midgut glands, adding other by-products as necessary, and removing almost all free water to have a semi-bound water region, under normal pressure. Or it relates to dried pentofeed or bait characterized by being heated under reduced pressure and dried by microwaves down to the bound water region.

In the dry pet food or feed of the present invention, the midgut gland of a cephalopod or a mixture of this and other by-products is mixed with various raw materials.

Various raw materials used in the present invention include fish meat, livestock meat and their by-products, starch, soybeans, processed soybeans, and mixtures thereof.

The slurry made by mixing the ground midgut glands or by-products with the ground midgut glands may be used as is, or may be in the form of a slurry in which starch, grain flour, soybean flour, okara, etc. are dispersed or emulsified.

Moisture in the semi-bound water region of the dough can be adjusted by adding dried or powdered food to crushed midgut glands or a mixed slurry of this and by-products, or by adding crushed slurry to the raw material. After dispersing, for example, steaming and shaping, it is dehydrated and pre-dried using a water absorbent, sunlight, hot air, infrared rays, cold air, etc., and adjusted to semi-bonded moisture. It is something that

The dough containing midgut glands or a mixture of midgut glands and by-products and having a moisture content adjusted to a semi-bound water region is preferably subsequently heated and dried by microwaves to dry to a bound water region.

In addition, drying can be performed appropriately by air drying, hot air drying, or the like.

The end of the microwave drying is a moisture range with a water activity value of 0.7 or less.

The dry pet food or bait of the present invention can be stored for a long period of time,
Moreover, it is extremely easy to eat.

The present invention will be explained below based on Examples.

Example 1 Pig liver was sliced and immersed in a gelatinized slurry made by crushing the midgut glands of a giant water octopus.
The gas was placed under a reduced pressure of 1 liter to replace and disperse the gas in the capillaries of the liver. Next, it was spread on a net and dried through ventilation to a semi-bound water region with a moisture content of 33%, and then microwave dielectric heating was performed under a reduced pressure of 30 tools to dry it to a bound water region with a moisture content of 10% or less. I forced it. Due to the dispersion of the midgut gland slurry, this product did not harden due to drying, unlike pure dried pork liver products, and maintained supple physical properties for a long period of time.

The resulting pet food was highly palatable to dogs and cats.

Example 2 50 parts of the midgut glands of Japanese common squid and 50 parts of beef liver were crushed,
To this, 1 part of common salt was added to gelatinize it, and 30 parts of beef tender skirt, 20 parts of beef tallow, and 20 parts of beef bone meal were added and emulsified and mixed to obtain a foamed dough with a free water range of 72% moisture. .

This was deposited on a Teflon net conveyor to form a molded product with a diameter of 12 mm and dried through air to reach a semi-bound water region with a water content of 26%. This was heated by microwave dielectric to swell it to make a dog food with a moisture content of 12%. This pet food has a squid component that masks the odor of Bork Lever, making it a highly palatable pet food.

Example 3 After the antioxidant BHA emulsion was infiltrated into pork ribs, the slurry of Example 2 was applied in a dot shape to the ends of the cut ribs, and the electric field density of the microwave was lowered to 111 parts and 1 kg-hr. Dielectric heating is applied to selectively temporarily solidify only the slurry.
After reaching the quasi-bonded moisture region, the electric field density was increased by 7 times to cause swelling and drying to a moisture content of 13% to produce rib snacks for pets. This item had a nice appearance with red tulip-shaped livermeat attached to glossy white ribs, and was extremely popular as a pet.

Example 4 A slurry obtained by grinding 120 parts of the midgut glands and 25 parts of the gonads of a squid was added to 50 parts of sardine powder that had been degreased by heating and drying under reduced pressure, and a colloid in the semi-bound water region with a water content of 28% was made using a silent cutter. This was pressed into a stick shape through a nozzle with a diameter of 7 mm, and was expanded and dried by microwave dielectric heating. This product was found to be a cat food with a higher bite than pure sardine products, and it was determined that the effect of the addition of midgut glands made the cat food more palatable.

Example 5 86 parts of internal organs, mainly the midgut glands, of a grape squid were ground and crushed, and 5 parts each of blood plasma and isolated soybean protein, 2 parts of propylene glycol, and 1 part of BHTo were vacuum mixed and emulsified to remove moisture. A 72% slurry was obtained. After molding this into the shape of a large and small squid, it was wrapped in a water-permeable film, buried in an instant water-absorbing agent (example: MT-88 manufactured by Sumitomo Chemical Co., Ltd.), and refrigerated at 0°C for 4 hours. When it was removed from the package and subjected to a moisture absorption test using unfrozen water and silica gel, it was found that it had been dehydrated into a semi-bonded water region with a composition of 22.8% weak semi-bonded water and 21.6% strong semi-bonded water.

This was then dielectrically heated under reduced pressure with a degree of vacuum of 15 tools at a microwave output of 1 kW/1 kg hr to obtain a similar squid-like bait with a moisture content of 12%. This bait has a long shelf life and has been used as bait for large and small fish, resulting in extremely high fishing results.
