Description

Dry pet food

Area

The present invention relates to pet food in the form of a dry food tablet. In particular, the pet food in question is complete feed suitable for domestic domestic animals such as dogs and cats, prepared entirely from locally produced raw materials without any preservative or other additives.

Background

As a pet food, the use of dry food is popular for easy feeding and easy storage. In spite of some prejudices, dry food is usually excellent in its nutritional composition. Typically, dry food contains up to 15 percent residual moisture in addition to nutritious raw materials, which, thanks to its low liquid content, and more specifically its low water activity, maintains the microbiological quality of the dry food for a very long time.

Dry food consists of either individual pieces or a mixture thereof. Pellets, biscuits and chips are included in separate dry food pieces, but the dry food may also be in other forms, such as powdered, fresh or frozen. Due to its hard structure, dry food removes plaque and thus cleans the animal's teeth.

Most pet dried foods are made by cooking extrusion. In extrusion, or extrusion, the raw material mixture is moistened and fed to an extruder, where the pulp structure is pressurized and usually at a temperature above 100 ° C, after which the pulp is squeezed through the nozzle to the desired shape. Although the process is fast, the hot temperatures required by the process can significantly reduce the amount of some natural antioxidants and vitamins. After extrusion, the extrudates are dried to the desired moisture level. Another alternative to preparing pet dry food is cold pressing using special cold pressing techniques typically at temperatures below 75 ° C. Cold pressing is done mechanically without the use of separate solvents or liquid addition.

There is a clear difference between extruded and cold pressed food presses. Extrusion food presses are typically products of an industrial design of physical size as compared to beam cold press extrudates. There may also be differences in the absorption of nutrients from dry foods prepared by various methods. Pressed cold-pressed food disintegrates rapidly in the gastrointestinal tract and absorbs nutrients more uniformly and faster than extruded food. Likewise, cold pressed pressed food does not cause the dog to swell the stomach like a digestive and absorbent extrusion product later in the digestive tract. There is a clear need in the pet food market for alternative, high-quality but cost-effective dry food products that can withstand the burden of transportation and storage.

BRIEF DESCRIPTION The object of the present invention is to provide a novel type of dry pet food which is close to complete feed made from the raw materials produced without any preservatives or additives, which covers all the animal's nutritional needs and does not require any other nutrition for nutritional reasons. It is a further object of the invention to provide a pet food made from high quality raw materials that can be prepared so that the final product has a good value for money and excellent shelf life under normal conditions of storage.

The objects of the invention are achieved by dry pet food, characterized in that it contains 0% to 55% cereals, 0% to 30% fish meal, 0% to 55% potatoes, 2% to 45% processed animal protein, 3% to 20% vegetable oil or animal fat. or oil-containing seed meal and 0.1% to 15% beet cut, vitamins and minerals or berry and fruit preparations containing them, and substantially compressed into a rod-shaped or molded form. Typically, the food press is a pellet.

Preferred embodiments of the invention are the subject of dependent claims.

The composition of the invention is pelleted from the disclosed raw materials. Pelleting, or Cold pressing, preserves the nutrients naturally without the oxidizing and hydrolysing effect of the heat treatment. In addition, it preserves natural heat-sensitive vitamins, both in the raw materials, added and the colors and aromas, minerals and vitamins. In the dry food pellet according to the invention, the nutrients are in proportion to the animal's nutritional requirements.

Different raw materials have different pelletizing pressure and humidity values. An excessively moist feedstock will not pellet properly and may cause rapidly developing qualitatively negative properties in the final product. On the other hand, too dry a raw material causes technical problems in the field equipment and in the stability of the final product. The invention is based on the fact that the raw material composition according to the invention is optimal for pelleting and provides pellets which are resistant to transport and storage without crushing without the use of synthetic / modified binders and / or excipients.

The individual pellets, typically about 5 mm to about 25 mm in length and typically about 4 mm to about 12 mm in diameter, have a significantly higher density than the raw materials used, i.e. the same amount of nutrient and energy is compressed into a smaller space. The pellets according to the invention are of uniform quality and very resistant to handling. The pellets according to the invention can be produced to a great extent at a reasonable energy consumption, which reduces the cost of the product and thus the price of the product and thus also the consumer satisfaction.

Description of the Invention

Pet refers to domesticated domestic animals, such as dogs or cats and rodents.

Dry food refers to food prepared by cold pressing / pelleting, consisting of individual pieces or a mixture thereof. Pellets, extrudates and chips are among the dry food extrudates according to the invention. "Feed" in this context means the product intended for oral animal feeding. Complete feedingstuffs are defined as feedingstuffs which cover all the nutritional requirements of an animal and which, for nutritional reasons, do not require any other nutrition.

According to the invention, a raw material composition suitable for cold pressing has now been developed comprising, on a case-by-case basis, cereals, fishmeal and / or potatoes, in addition to animal protein preparation, oil, beet pulp and berry meal treated as conventional ingredients. In addition to these, the composition may include nutritional supplements such as vitamins and minerals. The raw material composition may be grain-free. In some product forms, the raw material composition does not contain fishmeal and / or potatoes.

In one embodiment, in addition to the usual ingredients, cereal-based raw materials are preferably about 40% and fishmeal about 23%, in another embodiment cereal-based ingredients about 24% and processed animal protein about 18% and no fishmeal at all. In one form, about 38% processed animal protein and about 42% potato-based raw materials and no cereal-based raw materials.

The cereal used in the composition is preferably oats, but may also be, for example, wheat, broad beans and other protein-rich pulses. The fishmeal raw materials are preferably herring and / or sprat. The potato is preferably potato flakes or potato flour. The oils are animal or vegetable fats, the animal fats are preferably, for example, chicken fat and the vegetable oils are naturally high energy, soft fat oils or seed rags without added oil or fat such as linseed oil or linseed oil, camelina oil, edible oil. The processed animal protein preparation is preferably chicken, cattle, pig, sheep or MDM (Mechanically Deboned Meat), the meat may also be game meat. The animal protein preparation may also contain egg or egg products. The beet cut is preferably molasses. The berry flour is preferably dried and ground berry flour made from wild berries, for example blueberries, by drying and grinding or by-product obtained from juice obtained as a by-product of juice production.

The selected raw material composition does not require synthetic / modified binders and excipients to stay cured after cold pressing. The fish oil or other fat-containing ingredient according to the invention causes the raw materials to adhere to the compression channel of the matrix used for pelleting, whereupon pelleting can be initiated. In addition, the friction produced by compression generates heat to such an extent that the starch in the raw materials is bonded to strengthen the structure of the final product. However, the temperature does not rise above normal pasteurization temperatures, about 70-80 ° C, during compression.

The pet food dish according to the invention is prepared from the above-mentioned raw material mixture by pelleting machine compaction into a mixture, a pellet. The cold-pressed pellet is formed in the compression channel of the matrix inside the pellet press. In simplified terms, the pellet press operates by feeding the raw material to the surface of the perforated matrix, from which the so-called "matrix" rotates. pulley wheels force the raw material out of its way into the holes in the matrix. Generally, the pelletizing machines used are either flat matrix or ring matrix machines. The optimum ratio of the length of the compression channel to the cross-sectional area of the channel used in the present invention may range from about 0.8 to about 15. The resulting pellet is typically cylindrical or rod-shaped and shaped in cross-section. However, its shape may vary according to the shape of the press passage of the pelletizing machine available at any given time.

The raw material mixture is pressed at room temperature. The heat released by the compression can be removed from the compressed pellets by means of an air stream, thereby strengthening the pellet structure during cooling. The maximum pellet length can be adjusted, if desired, with a cutter placed behind the matrix. The pellet may be "frozen" to improve the nutritional composition and / or palatability, for example, in a drum blender or vacuum mixer, to optimize the nutritional properties of the product or to improve the palatability of the oil-flavored or oil-flavored spice or blend.

The pelletized dry food according to the invention is useful as such. It can also be mixed with water. The nutritional requirements of a pet can vary greatly depending on the species, age, breed and activity level of the animal, so the dry food of the invention is administered to the animals according to their individual needs.
