Definitions

  • the invention relates to a particulate animal feed, in particular dog and cat feed, with a dry matter content of less than 40% by weight, based on the total weight of the animal feed, the particles being built up in layers.
  • the invention further relates to a method for producing such animal feed.
  • Known ready-to-eat foods for pets such as dogs and cats are usually divided into three groups.
  • Wet foods usually have a moisture content of 60 to 80% and are usually offered as canned foods. These foods must be sterilized to preserve them.
  • Semi-moist feed has a moisture content of 20 to 50%.
  • Such feeds need additives to ensure durability.
  • additives used are sugar, propylene glycol, glycerol, antimycotics and other preservatives. These additives have the disadvantage that they reduce the palatability of the feed and are nutritionally questionable. The buyer of such feed often reacts negatively to chemical additives in the feed.
  • Dry feed usually has a moisture content hold of 10% and are practically feedable for the pet owner. Due to the low moisture content, dry feeds have a good shelf life and storability and do not require any special packaging such as canned feed or semi-moist feed. However, such dry feedstuffs are not so tasty for the animal, since the taste sensation depends, among other things, on various water-soluble substances and the contact of these substances with the taste receptors.
  • the low water content of dry food is also disadvantageous for nutritional reasons, especially in cats.
  • the dog can compensate for the low fluid intake when consuming the dry feed by increasing the intake of drinking water.
  • the cat is unable to do this due to its regulatory mechanisms.
  • This deficiency is known, e.g. remedied by adding NaCl so that the animals feel thirsty and drink more fluids.
  • This is not advantageous for medical reasons, since high NaCl intakes can lead to health problems, especially since in older animals, which often suffer from chronic kidney diseases, a high NaCl content in the diet can lead to additional damage to the kidney.
  • the present invention provides a wet food for animals which has a dry matter content of less than 40% by weight and thus has a relatively high moisture content of more than 60% by weight, corresponding to a wet feed.
  • the handling, location and resistance to spoilage should correspond to that of a dry feed.
  • the animal feed is characterized in that at least one moisture core is provided, which consists of a core containing water from a water-impermeable covering layer, the moisture core being surrounded by a nutrient layer which has a dry substance content of at least 80% by weight.
  • FIG. 1 is a cross section through a first embodiment of an animal feed particle according to the invention and FIG. 2 is a cross section through an animal feed particle of a second embodiment.
  • a particle of the particulate animal feed consists essentially of a moisture core, which is formed from the water-containing core 1 and the covering layer 2, and from the nutrient layer 3, which surrounds the moisture core on the outside.
  • the particles can be made in any size.
  • the water-containing core 1 preferably has a diameter which is between 3 mm and 20 mm.
  • a polygonal or round shape of the particle is preferred because such shapes have the greatest stability and are easy to produce.
  • the water-containing core 1 consists either of pure water or of water with added flavors and / or other additives such as e.g. Gelling agents, alginates, pectins, etc.
  • the flavors can be water-soluble or water-insoluble.
  • the generation of the moisture core or the water-containing core 1 can take place using encapsulation methods which are conventional per se.
  • the covering layer 2 is waterproof and is suitable as a material Various water-impermeable substances known from the food or animal feed sector, such as hydrogenated fats and oils, fatty acids, waxes, mixtures of waxes and fats, gelatin gum, gum arabic, ethyl cellulose, water-insoluble polymers with a melting point of about 110 ° C., polyamides, etc.
  • the nutrient layer 3 consists of a nutrient mixture as required for the respective type of feed.
  • Vitamin A I.E./kg 8,000-80,000
  • the nutrient layer 3 preferably has a moisture content of less than 20% by weight, preferably 10% by weight.
  • the dry matter content of the nutrient layer is therefore in the range greater than 80% by weight. Falling below this range entails the risk of corruption.
  • a range from 80 to 95% by weight is advantageous, in particular 90% by weight.
  • the dry matter content of the entire dry feed according to the invention is, as already described above, below 40% by weight and preferably around 30% by weight. With a volume ratio of water core: nutrient layer of approximately 3.7: 1, the dry matter content is 27% by weight. This corresponds to a nutrient layer approximately 1 mm thick with a total particle diameter of 20 mm. Similar dimensions can exist for other particle sizes.
  • the water is frozen in a known manner for better processability and surface stabilization in small polygonal or round particles.
  • An advantageous particle size is approximately between 3 and 20 mm, and smaller or larger diameters can also be selected. This process takes place in deep freeze systems or liquid nitrogen freezers. For example, appropriate water droplets are sprayed into liquid nitrogen.
  • the solidified water particles are subsequently coated with a film of the selected coating substance in order to form the coating layer.
  • these are heated to a temperature above the melting point and the water particles are then coated by means of spraying or other conventional encapsulation processes. Due to the low temperature of the water core, the molten shell solidifies immediately on the surface of the frozen water particle and forms a continuous water-impermeable film on the still frozen water particle.
  • the thickness of the envelope layer is to be dimensioned such that the particle is stable enough for further processing.
  • the moisture core formed in this way which is closed off by the covering layer 2, is further coated with the nutrient layer 3 by spraying, rolling or other methods.
  • the nutrient mixture can be a customary extruded or pelletized and granulated dog or cat food, or can also be in powder form from the usual raw materials. The standardized values for the ingredients must of course be observed.
  • the particles obtained in this way are then fed to a drying process, which in any case must take place at a temperature which is below the melting point of the hill layer 2.
  • the nutrient layer is dried to the required extent by the drying process.
  • the moisture content should be below 20% by weight and is preferably about 10% by weight.
  • the feed After the drying process, the feed can be packaged in the usual way, whereby no special packaging measures, such as moisture sealing, have to be observed. Due to its structure and the dry layer of nutrients, the feed can be stored for almost unlimited time.
  • the feed particle shown comprises not only one but several water-containing cores 1, each of which is surrounded by cladding layers 2.
  • Several such moisture cores lie in a matrix from the nutrient layer 3.
  • the substances and mixtures of substances from which the water-containing cores, the covering layer and the nutrient layer consist can correspond to those described above.
  • the moisture values are also the same.
  • the size of the encapsulated water-containing cores (moisture cores) is preferably in the range from a few 200 to 500 ⁇ m in diameter, but can also be considerably larger. Suitable manufacturing processes for manufacturing such encapsulated water cores have also been known for a long time.
  • the feed is made so that the encapsulated water particles in the
  • round or polygonal water particles with defined diameters are listed here, this does not mean a strictly geometric shape. This includes all particle shapes (e.g. teardrop shape) as they arise in the encapsulation process.
