Foodstuffs and process for their manufacture

The invention relates to a food: and its manufacture. In particular, the invention relates to a soft food which is particularly useful for use as animal food, especially suitable for dogs and cats; however, according to the invention Food is given a composition that is also suitable for use in human nutrition power. This food is characterized by its soft, meat-like texture and thereby from that it can be stored without being previously sterilized and without being kept in hermetically sealed containers to have to.

The currently available pet foods that are classified as

Dog and cat foods on the market, let ^f into three different groups:

1) Canned Foods - These products are made up of from meat or mixtures of meat and cereal products obtained by heat sterilization in hermetically sealed containers are preserved. The moisture content of these products is usually about 70 to 80%.

) Dry or semi-dry foods - these products consist of mixtures of meat and / or Meat meal and cereal products and have a moisture content so low that that Product is protected from spoilage. In general, the water content is below 12%, but it can be up to 16% used when adding potassium sorbate or other anti-fungal agent. Because of the With low moisture content, these products are generally hard and brittle.

3) Semi-moist or soft-moist products - these products consist of mixtures of meat, protein flours and cereal products; they stand out for their soft-moist nature attributable to a moisture content between 25 and 45%. The preservation takes place through dissolved substances (glycols, sugar and polyvalent alcohols), which the reactivity of the water, and by potassium sorbate or other preservatives.

From these groups are the dozed foods generally accepted by animals because they are a natural moist consistency and a high meat content

409812/0989

to have. The high moisture content of these products makes it necessary to keep them hermetically sealed Containers, for example in cans or in sterilizable flexible packaging, to be sterilized by heating. Because The bulk of these foods, which often contain 75 to 80% water, is packaging in general more expensive than, for example, dry or semi-dry products.

The dry or semi-dry foods have in most cases because of their low moisture content high calorie content and can be a balanced animal feed in terms of its nutritional content form. Their shelf life is due to the low moisture content sufficient, and you can use paper, cardboard or other cheap packaging containers or even transport them in bulk.

On the other hand, animals are reluctant to accept products that are dry and hard, especially when it comes to cat food and many pet owners reject this method of feeding their pets because the feed bears no resemblance to animal feed containing meat. It is known per se that by adding a meat pulp, .the on the outside of a made on a grain basis, dry Animal food adheres after previous heat coagulation and drainage, the food from the animals sooner Is accepted. But even if the food produced in this known way is preferred to be consumed, it retains it the product still has its hard texture, and obviously food would have an outwardly softer texture even better to be taken.

409812/0989

- If -

Compared to other types of pet food the semi-moist or slightly moist foods · - offer the advantage of a meat-like texture and high in calories; furthermore, they do not need to be sterilized in sealed packaging for preservation to become. The food is more easily accepted by the animals than dry food and the nourishing components of the feed consists of meat, meat meal and cereal products, mixed with enough water that the desired texture is achieved. Sugar, propylene glycol and polyhydric alcohols are added, to bring the reactivity of the water below 0.88% so that bacteria do not multiply while an anti-fungal agent may be a necessary one Constituent part to prevent the growth of yeasts and molds. The preservatives are however, by many veterinarians and animal nutritionists regarded as undesirable in the diet because of the disease have been determined and assigned to these components. Another disadvantage is the need moisture-proof packaging to prevent the product from drying out during storage will.

The invention is based on the object to develop a food that the benefits of the group with little Has moisture content and the soft-fleshy Possesses quality which is desired by the animal as well as by the pet owner.

According to the invention, a food is proposed for this, which is of plastic consistency and in particular contains protein-containing animal meal, the particles of which are predominantly less than 100 η in size, which in one

409812/0989

Oil or fat carrier is suspended as a dispersant, the total oil or fat content between 10 and 60% the total weight of the product and the moisture content of the product is less than 20% by weight.

The invention also provides a method of manufacturing of a food with a plastic consistency; according to this process, a mixture of one proteinaceous meat and bone meal and an oil or fat carrier, the total oil or fat content of which is between 10 and 60% by weight of the mixture makes up, and is then the particle size of the solid component of the mixture reduced so far that most of the particles at most 100, u are large and then the mixture is worked through until the oil or fat acts as a dispersant in the mixture.

The food according to the invention can also be produced in this way. be made that first the largest of the solid constituents of the mixture is reduced so long until most Particles are still at most 100 u, and then that MBM treated in this way with the oil or fat carrier in is mixed in such proportions that the total content of oil or fat in the end product is between 10 and 60% by weight.

The food according to the invention has a soft, pliable or plastic consistency j and in one embodiment the product can be cut into pieces for sale shape the desired shapes and dimensions. Because of its plastic nature, the product is made by animals more easily accepted than the known dry or semi-dry feed, and furthermore it can because of its low moisture content, which is comparable to the water content of a dry or semi-dry food.

409812/0989

cash, can be packed in any kind of cheap packaging that is used for dry food. Consequently are the more expensive moisture-proof or hermetically sealed containers that are used for the well-known, semi-moist or dozed types of food are required for packaging the product according to the invention dispensable.

Because of the low moisture content of the named product, you need it in semi-moist foods necessary ingredients to reduce the reactivity of the water and prevent the yeast and Mold growth not to be added. This acts it is an important aspect of the invention in view of the stated objections to the addition of preservatives.

Finally, there is no need for pasteurization, sterilization or low temperature storage either, and the product does not suffer deterioration or dehydration damage when exposed to air; it rather, it is permanent for an indefinite period of time.

In a particularly important, modified embodiment the food product according to the invention can be used as a topcoat or part of a topcoat for a dry Foods are used. In this embodiment, the invention provides a food with a core mass from floury and / or proteinaceous material, which is processed in a suitable manner and a piece or Has pieces of the required shape, this core mass is surrounded by a tough, sticky covering layer of considerable thickness made of a soft or plastic material, that consists of a product or contains a product that

409812/0989

has fine-grain proteinaceous meat and bone meal, wdbei most of the particles are not larger than 100 ^ u, suspended in an oil or fat carrier as a dispersant, with a total oil or fat content between 10 and 60% by weight, based on the product, and a moisture content of the product of less than 20% by weight.

The product made according to the invention is derived from animals gladly taken, but required because of the low moisture content the top layer that deals with the moisture content of dry or semi-dry foods is comparable, no drainage, no storage under cold room conditions and no hermetic packaging tight containers to prevent dehydration. Furthermore, no components need to be added »the the well-known semi-moist food types of the same consistency are required to ensure the reactivity degrading water and growing yeasts and Prevent mold.

The cover layer, in which the core material is enclosed, can be composed of components which are selected in this way will ensure that optimum smell, meat-like consistency and appearance are achieved; this layer is in of considerable thickness evenly applied to the surface of the core mass.

The core mass can be made from any number of types of relatively inexpensive substances as required Have nutritional value, preferably from a mixture of proteinaceous and floury. Substances, for example Grain products, oilseeds, meat or fish meals and other substances common in such products.

409812/0989

The substances can be cold-pressed or any other expansion processes can be combined and brought into the desired shape, with the starch components gelatinizing and when they are press-molded, they get the shape and size you want.

The core mass can also consist of a plasticized mixture of protein-containing flour, cereal products and Oils and / or fats are produced, which are brought into the desired shape and size by extrusion can be.

This application also specifies a method for producing one of the products defined above. Here, the coating material is treated in such a way that it becomes liquid or flowable, for example by heating, and in a liquid or flowable state it is called Layer brought to the surface of the core mass, e.g. by dipping, circulating, spraying or the like ... If that Coating material has been heated, it will after the coating process cooled, preferably on Room temperature.

The product produced in this way does not have the defects that are encountered in foods with the usual ones flavor-enhancing sprays or similar treatments, because of the thinness of the applied layer, the core mass could be detected by the animal through sensory perception; but also the disadvantages of the coated products forming meat juice do not arise, although in use the Core mass is exposed because the water leaches the coating as the meat juice is formed.

409812/0989

Another feature of the product according to the invention is that the top layer can cope with the efforts of the Dogs, cats and other animals resist, the better tasting parts of a feed mix take out and eat while the rest is left.

The food according to the invention in the coating of the product according to the above embodiment is of course according to the methods described above.

The protein-containing animal meal component of the inventive Food may contain the following substances: meat meal, meat and bone meal, blood meal and thickened meat loosened; also poultry meal, meal from poultry ingredients; Fish meal, meal made from fish ingredients, thickened fish liquor; or egg powder and similar dry egg products. The oil or fat carrier can are obtained from animal fats, for example from beef, sheep, pork, poultry or fish fat, or from vegetable oils, e.g. from seed oil, soybean oil, sunflower oil, saffron, cottonseed, rapeseed or linseed oil.

In addition to the protein-containing animal meal and the oil or fat carrier, the food according to the invention can contain other Contain nutrient components, especially protein components such as derivatives of grain crops such as wheat, corn, rice, soybeans, navy bean or flaxseed. the Starch in these cereal ingredients can be gelatinized * or in natural form. Besides salt you can Furthermore, additives with a high protein content from yeast and milk or milk products are provided, for example Casein, casein sodium, co-precipitate and whey.

409812/0909

So that the food is a complete and nutritionally balanced feed represents, you can add vitamins and minerals and other feed additives, for example Antioxidants, stabilizers, odorants, odorant precursors and odor enhancing substances. In addition, as will be described in detail below, the food may be an emulsifying agent, for example Contains lecithin, mono- or di-glycerides, sorbitans and polysorbates in a proportion between 0.05 and 2% by weight '. As a particularly preferred emulsifying agent, lecithin is used in an amount between 0.5 and 1.0% by weight *

Since no substantial amounts of water are added, the moisture content of the product will generally range between 3 and 20%, but will depend on the moisture content of the various substances used to make the product. Generally the moisture content will be around 10 to 12 % of the product.

In order to improve the appearance of the product and to make it more pleasant for the consumer, one can use a suitable dye to add. Most of the water soluble dyes are however, to produce coloration due to the lack of added water in which the dyes are dissolved could not be suitable.

The dye can be added to the product in other ways, for example by adding something serious Ii rather dye is introduced into the drying process in the manufacture of the protein-containing flour. Accordingly, if a

409812/0989

gelatinized flour of cereals is incorporated into the product, a water-soluble coloring material in the process Manufacture of this component can also be incorporated. Water soluble dyes can also be used with the crushed Flour in the form of a water-in-oil emulsion are mixed into an aqueous dye solution with the aid of a suitable emulsifying machine in the added oils or Fats is incorporated. A specially formulated oil or fat soluble dye can be added to the oil or fat before its Incorporation into the food can be added, or preferably a dispersed colorant, such as a Lackdye, added to the mixture of substances in order to achieve useful colorations of the end product. To get in the meat-like properties of the To highlight product, fiber material can be added to the crushed flour or plasticized product will. The fibrous materials can be animal or vegetable Be of origin; For example, one can use animal protein fibers, fibers spun from vegetable protein, Cellulosic fibers or fibers derived from polysaccharides use.

The external appearance can be further improved by mixing it into the product or on its outside colored or uncolored individual particles are applied, for example soy flour, soybean particles, Cooked particles, protein-containing flours and pieces of cereal.

A common product made according to the invention thus contains high quality meat and bone meal, a Grain ingredient, such as navy bean flour, a polyunsaturated one Vegetable oil, for example sunflower oil, Vitamins, mineral salts, salt and a coloring material.

40981 2/0989

The proportions of meat meal and bone meal and meal of cereals are controlled so that after the addition of oil, the oil content is generally more than 10% and less than 20%. The oil content is decisive for achieving the plastic nature of the product and the theological properties of the product, which has a moisture content of less than 20%, due to the type and amount of oil or fat, used in the product.

As indicated above, the preferred method for preparing the food according to the invention is that the particle size of the mixed with the oil or fat fixed portion for example by means of a roller driver or another suitable grinder so far is made smaller that most of the solid particles are less than 100 µg in size.

After grinding, these mixtures are generally in the form of dry flakes or dry dust, with the fat or oil content of the mixture is discontinuous Phase represents.

In this phase, the fat can be processed by working the mixture and preferably by incorporating an emulsifier, such as lecithin, are converted into the dispersion phase, so that a plastic mass is formed. This operation can be done in batches by using a roller mill, Pfleiderer mixer or other suitable Mixer, or continuously in a suitable extruder. The plasticizing process is improved by adding a suitable emulsifying agent to the mixture, and one can also add the fat or Reduce the amount of oil required to obtain a product from

409812/0989

2345988

plastic consistency is required. The emulsifier generally makes up 0.05 to 2% of the amount of feed, but depends to a large extent on the type of food used emulsification aids.

Should the food product according to the invention be used as a coating layer are used in the sense of the embodiment described above, the cover layer can be applied to the core material can be applied by several different methods, but the preferred methods are heating of the coating material to a temperature so high that the material becomes flowable and the inclusion of the core mass by pouring the coating over the core material or by circulating the core material and the heated coating mixture Each piece of this forage product can contain more than a single core mass body and in each one In this case it is important that the coating layer really does all Covering surface parts of the body or the bodies that make up the core mass.
