Process for improving the Vohlgeschijacka

The invention relates to a method for improving palatability of animal feed.

Dried animal feed in particle form or animal feed with a low or medium moisture content is generally considered to be the best diet for animals. In Trookenprodukten this type is typically among others small Sinielpartikel, shaped as Strangpreeatüeke in the manner known from TFS Patent 3,119,619 ways, including baked · or dried lekse odor pieces · as si · ame the TIS-Patentaohriften 309,505 and 1 354 968 are known, or, among other things, lügelohen, via si · from ITS Patent Bulletin 2 168 532 bakasat.

Particles typically have a moisture content of up to 10% by weight. Intermediate products with a moisture content Clay about 30 wt. - 6 can be found in the US patent 3 202 514 known Veiee. Dry products or intermediate products have the disadvantage that they are not preserved in cans in the same way for animals as the normal ones Feed types are. The canned foods, on the other hand, are not as nutritious as dry foods, and some of them are vaguely of a much greater moisture content, usually about 75J6. Flere soaps, however, often have a clear preference for the canned food, brook or Zvisohen food It is not so readily accepted by the animals as is the case with canned food.

It has been established that the palatability is possible of dried animal fodder or of animal fodder with a moisture in the intermediate range up to one Increase point su, in which the animals accept a dry or intermediate product without further ·· · Da · method for increasing the The palatability sees the addition of something that increases the palatability SSure to the futtex compound gate. The acid can be added to the feed particles in order to cover a greater part of the exposed area the particles need in any case not a continuous film or a continuous layer applied to verden. linear, exposed areas of the paxicle surfaces, which are not covered with acid do not prevent that the areas covered with starlings are a significant improvement in the particle taste. The inorganic or belong to the taste-improving men Mineralisohen sturgeon, the sulfuric acid, hydrochloric acid and phosphoric acid and aie organic influences like citric acid, veina & ure, Fumarsture, lactic acid, Issigeture «ad Eayaminsture (C5Hi3yO; S).

It has been established that phosphoric acid, citric acid, and hexaic acid produce the greatest increase in the acidity of the acid in the addition of fine hens. The acid can be added in amounts ranging from about 0.05 to 5% of the feed particle, depending on the acid used. However, the beroriugte Zusatzbereioh for phosphoric acid is 0.55 Di "V £" The preferred Zueatabereioh citric acid is 0.5 FCIE 1% · boron preferred additive range for Ilexaainsäure etva is 0.05 to ¹ to 0.5%.

The coated particles can have the acids which improve the Vohlgesehmaek in a concentrated layer on the particle surface. You layer can be hergeetellt da.duroh that the Gäure is applied to the exposed surfaces of the particles, or d * ß the acid is applied to particles which have been provided with a Fettaohient, but the Sohioht need not be continuous. Hit acid coated particles can be coated with an outer layer of fat. The acid layer can also be produced by coating the FartilÄl with a dispersion of fat and acid. 5 bJLe 12 ^ of an edible fat, preferably an animal fat, for example son wood or tallow, can be added to the particles during the coating. The grease coating partially shields the particles from the influence of moisture and can function as a carrier for the acid. Suitable methods of applying the acid consist in spraying a concentrated solution of the acid or blowing the powdery or anhydrous acid onto the particles. The best way to apply the fat is by spraying it at a temperature above the melting point of the fat.

Since "not treated with acid" the product can be administered dry to the animals or it can be made damp with water. The acidity on the surface of the feed particles provides an unusual one and unexpected increase in palatability. When the animals eat the coated particles, the acid is present on the surface and comes into contact with immediately the organs of taste in animals. That stimulus, that acid supplies, is thus achieved with low acidity, and the possibility of significant disturbance in the nutritional balance the feed particles are avoided. Every acid in the till of the lining material naturally creates an additional one Good taste while the animal is eating the food, although the (Jeechaacks improvement can't be as big as them is supplied by the aroaating acid that is present in the Surface is present.

The added acid also acts as a preservative or as an anti-mycosis agent and combine a spoilage ale Consequences of contamination. The ion preservation effect can be increased by adding »additional preservatives or anti-myoss agents or Humectansen in connection with the taste-improving Acid can be used. Propylene glycol, potassium sorbate, Sorbic acid, BHT, BHA, i'thoxyquin or other equivalent substances can be used with the acid as a preservative.

The invention is explained in more detail below with reference to the following examples, which are preferred embodiments of the invention are intended to represent, but not the scope of the invention should restrict.

The cylinders with increased moisture were then coated with 16 parts by weight of molten grease on each 182 parts of cylinder bit of increased moisture, while the soaked grease was injected into the rotating cylinder. After the fat had been added, the tube was kept running until the cylinders were essentially uniformly layered with the fat. Seeds were blown into a stream of gas in a stream of phosphoric acid in the form of a gas, the flow continuing until the particles were essentially uniform were coated. The coated particles had a coating consisting of SJd sustttsliohem fat and IJt phosphoric acid, based on the seeds of the coated cylinders.
