Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a pet food for improved animal palatability and storage stability,

The present invention relates to a method for producing a feed for companion animals having improved palatability and storage stability.

Recently, as the number of companion animals such as dogs and cats increases worldwide, diseases such as adult diseases such as obesity, diabetes, and liver diseases caused by aging of animals, lack of exercise, nutritional excess, and the like have been increased.

In this regard, many feeds have been developed to prevent obesity and weight gain in companion animals. For example, a feed containing a large amount of unsaturated fatty acids having various physiological activities in large amounts has been devised.

However, feeds containing a large amount of such unsaturated fatty acids are easily oxidized depending on the preservation environment, thereby affecting odor and palatability. It is also known that when the minerals such as copper, iron, manganese, cobalt and the like are mixed with a fat-containing fat containing a large amount of unsaturated fatty acid, the oxidation reaction of the fat is promoted and the storage stability is further lowered.

The inventors of the present invention have conducted studies to solve these problems and found that a complex of omega-3 fatty acid oil and protein containing a large amount of unsaturated fatty acid and a mixture of milk protein and protein containing a large amount of saturated fatty acid, It is confirmed that the palatability and storage stability of the feed for companion animal are improved by mixing the mixture with slow stirring to prepare a complex of fat and protein and then mixing with pellet and cereal, Thereby completing the invention.

Hereinafter, the present invention will be described in detail.

According to one embodiment of the present invention, there is provided a method for producing omega-3 fatty acid oil, comprising the steps of: (1) preparing a complex of omega-3 fatty acid oil and protein by mixing krill oil, krill powder, fish oil, water and pea protein with stirring at 1500-3000 rpm ; (2) preparing a complex of milk oil and protein by mixing chicken breast powder, fish protein hydrolyzate (FPH), corn gluten, water and milk oil at a mixing rate of 1500-3000 rpm while stirring; (3) adding the complex prepared in the step (1) to the mixture of fat and protein while stirring the complex and the vegetable oil prepared in the step (2) at 100-1000 rpm; (4) preparing a dough by mixing cereal powder, beet pulp, water and yucca extract into a complex of the fat and protein; And (5) steaming the dough at 90 to 130 ° C for 10 to 30 minutes, and extruding the dough at 140 to 170 ° C at 3 to 10 kg / cm 3 to form pellets. The present invention provides a method for producing an improved companion animal feed.

(1) the step of preparing a complex of omega-3 fatty acid oil and protein

First, in step (1), fish oil, krill oil, krill powder, water, and pea protein are mixed with stirring at 1500-3000 rpm to prepare a complex of omega-3 fatty acid oil and protein.

The fish oil is preferably an oil extracted from at least one selected from sardines, salmon, mackerel, herring, saury and tuna. Fish oil is rich in omega-3 fatty acids and has the effect of bringing healthy skin and glossy coat to companion animals.

The krill oil has a bioabsorption rate that is 1.6 to 4 times higher than that of common fish oil, and it can be increased to 43.5% for HDL and reduced to 34% for LDL.

The krill powder contains a large amount of amino acids such as alanine, methionine, and florin, proteins, chitin, and chitosan, and is effective for enhancing the immunity and enhancing the health and function of joints and cartilage.

Pea Protein is a plant protein component extracted and purified from pea. Unlike soybean, Pea Protein has a high non-GMO ratio, a high digestibility of 90 ~ 95%, and a very low allergen induction rate. Pea protein is rich in fiber, vitamin K, minerals, vitamin C, and high lysine content.

The combination of omega-3 fatty acid oil and protein is prepared by mixing 5 to 15 parts by weight of krill oil, 60 to 100 parts by weight of krill powder, 10 to 30 parts by weight of fish oil and 120 to 240 parts by weight of water, based on 100 parts by weight of pea protein .

Fats should be an essential part of animal feed, as animals are less likely to get fat, resulting in skin dryness, loss of hair, loss of quality, bad immune systems, and bad heart and joints.

Among them, an oil containing a large amount of unsaturated fatty acids such as omega-3 fatty acids (hereinafter referred to as "omega-3 fatty acid oil") must be included in the feed as it has a great influence on the healthy skin and coat of the animal, And when the unsaturated fatty acid oil is searched, unpleasant odor is generated, and the palatability of the companion animal is reduced.

Accordingly, in the present invention, the omega-3 fatty acid oil is mixed with high-protein krill powder, pea protein and water, followed by stirring at a high speed of 1500-3000 rpm to prepare a complex of omega-3 fatty acid oil and protein. The omega-3 fatty acid oil is stabilized by forming a complex with the protein, so that it is not easily smeared.

(2) a step of producing a complex of milk oil and protein

Next, a mixture of milk fat and protein is prepared by mixing meat crumbs, fish protein hydrolyzate (FPH), corn gluten, water and milk oil with stirring at 1500-3000 rpm.

The meat is preferably at least one meat selected from chicken meat, duck meat, venison meat, beef meat and pork meat, and may be used after being made into powder or finely ground.

The fish protein hydrolyzate (FPH) is a small hydrolyzed protein of less than 5,000 daltons (one oxygen molecule is 16 daltons and one carbon molecule is about 12 daltons) without being recognized by the immune system. Can be suppressed. In addition, since the digestibility of a young or old animal is relatively low, it is possible to increase digestion absorption rate by feeding a pre-digested protein in advance. Finally, when enzymatic degradation is performed among various hydrolysis methods, the flavor of the raw materials can be maximized. In the present invention, salmon protein hydrolyzate is preferred among the above-mentioned fish protein hydrolysates. The salmon protein hydrolyzate is a functional ingredient, which is also known as a "hydrolyzed salmon protein". The vitamin A contained in the salmon reduces the allergic reaction and is effective for preventing or treating eye diseases. In addition, it is preferable because nutrition is given to the skin and the hides and the rough skin is shiny.

The corn gluten refers to the remaining dry residue after separating most of the starch, embryo, and shell in the wet processing process for producing starch and syrup in corn. It is viscous and contains proteins (35-65%) and xanthophylls (200 ~ 400 mg / kg) and high digestibility.

In addition, the milk oil is added for supplying fatty acids and calories, and contains a large amount of saturated fatty acids.

The complex of milk oil and protein may be prepared by mixing 50-100 parts by weight of meat, 20-40 parts by weight of fish protein hydrolyzate, 40-60 parts by weight of milk oil and 120-240 parts by weight of water with respect to 100 parts by weight of corn gluten .

In the present invention, the milk is mixed with meat, fish protein hydrolyzate, corn gluten and water, followed by stirring at a high speed of 1500-3000 rpm to produce a complex of milk oil and protein. The milk oil is stabilized by forming a complex with the protein.

(3) a step of preparing a complex of fat and protein

Next, the complex prepared in step (2) and the vegetable oil are stirred at 100-1000 rpm while the complex prepared in step (1) is added to prepare a complex of fat and protein.

When the vegetable oil is added to the complex prepared in the step (2) and the mixture prepared in the step (1) is added and mixed at a low speed of 100-1000 rpm, It is possible to prevent the smell that reduces the palatability of an animal such as the fishy smell of fish oil contained in the complex, as well as to prevent the unsaturated fatty acid from being easily rancid.

The fat and protein complex may be prepared by mixing 5 to 15 parts by weight of the vegetable oil and 40 to 70 parts by weight of the complex prepared in the step (1), based on 100 parts by weight of the composite prepared in the step (2).

The vegetable oil may be at least one selected from the group consisting of sunflower seed oil, grape seed oil, olive oil, canola oil, almond oil, flaxseed oil, ham's seed oil and avocado oil.

(4) Step of making dough

The dough is prepared by mixing cereal powder, beet pulp, water and yucca extract into a mixture of the fat and the protein.

The dough is mixed with 60 to 80 parts by weight of grain powder, 5 to 15 parts by weight of beet pulp, 0.2 to 2 parts by weight of yucca extract, and 60 to 90 parts by weight of water at 45 to 65 캜 with respect to 100 parts by weight of the combination of fat and protein. .

The grains can be used as raw materials for rice, grains, beans, or papers, and are more beneficial to the nutrition and health of companion animals when they use grains cultivated in organic environmentally friendly manner. Specifically, the grain may be at least one kind selected from rice, barley, wheat, rye, soybean, and red bean, and is preferably used in powder form.

The beet pulp means a by-product obtained by extracting sugar from sugar beet. It is a safe fiber containing no toxin, and a waste puddle is discharged from the intestines so that the digestive system can be maintained in a healthy state.

The yucca extract is an extract obtained by extracting yucca root with water. The extract is a dark brownish odoriferous flavoring agent containing saponin glycosides. When added to feed, it improves the digestibility and reduces the smell of excreta when fed to companion animals.

In addition, 0.5 to 5 parts by weight of saccharide, 0.5 to 5 parts by weight of a mineral mix and 0.5 to 5 parts by weight of a vitamin mix may be further added to 100 parts by weight of the fat and protein complex.

The saccharide may be at least one selected from fructooligosaccharide, isomaltooligosaccharide, galactooligosaccharide, maltooligosaccharide, xylooligosaccharide, gentio oligosaccharide and agave syrup.

The mineral mix may contain one or more micro-minerals selected from the group consisting of calcium, phosphorus, sodium, potassium, chlorine, sulfur and magnesium which are required in large amounts in the body and iron, zinc, iodine, copper, selenium, , Chromium, fluorine, and molybdenum. Minerals form the skeleton of the bone and soft tissues in the body, maintain the acid base equilibrium, activate the enzyme, and maintain the body's osmotic pressure.

In addition, the vitamin mix may be prepared by uniformly mixing not only vitamin C, vitamin K, niacin (vitamin B group) that can be synthesized in the body but also remaining 13 kinds of vitamins to be consumed as food. Vitamins can be used as a non-energy source to support enzymatic reactions that allow food taken by nutrients to be absorbed, or to perform a variety of physiological functions such as DNA synthesis, bone development, cell membrane formation, blood clotting, and neurotransmission.

(5) Pelletization step

The dough is steamed at 90 to 130 ° C for 10 to 30 minutes, and extruded at 140 to 170 ° C at 3 to 10 kg / cm 3 to be pelletized. At this time, the size of the pellet to be produced is not particularly limited, but it is preferably 0.3 to 3 cm.

Next, the pellet prepared in the step (5) is dried at 90 to 130 ° C for 30 to 90 minutes. In particular, it is preferred that the pellets have a water content of less than 10% by weight by performing the drying step.

The animal feed prepared according to the method of the present invention described above can be prepared by preparing a complex of omega-3 fatty acid oil and protein containing a large amount of unsaturated fatty acid and a milk oil and protein containing a large amount of saturated fatty acid, The mixture is slowly mixed with stirring to prepare a complex of fat and protein, and then mixed with grains, beet pulp and the like and pelletized to improve palatability and storage stability.
