ABSTRACT:
FIELD OF THE INVENTION
This invention relates to a formed cream substitute for the addition to hot meals and a method for its preparation.
BACKGROUND OF THE INVENTION
It is common practice to add cream for the refinement of meals in order to improve their taste and creaminess. While a certain ropiness is desired, substantial thickening should not occur. By the addition of cream, a binding effect is not achieved. In contrast, the addition of cream can be noticed in the color by its whitening power.
The invention is based on the need to produce a portioned product capable of storage at room temperature. Which can serve as an equivalent substitute for the addition of cream for refining hot meals. The functions of cream, such as whitening power, sensation in the mouth, and taste, should be met. Moreover, the product must be readily dispersible and easy to handle.
Cream powder alone, which is commercially available, is not suitable for this purpose. It has a taste of dried milk, and when it is formed into cubes under pressure it can no longer be evenly dispersed.
From the German published patent application 23 26 114 corresponding to British Patent No. 1417952. a paste-like dried cream product is known, which contains spray dried butter powder, butter fat and/or animal or vegetable fats, starch, sodium caseinate and optionally vegetable binding agents and/or gelatin as main constituents. This known product contains 20 to 40 parts by weight of starch and is therefore strongly binding and not suitable as a cream substitute.
It is an object of the present invention to produce a portioned product capable of storage at room temperature which can serve as an equivalent substitute for the addition of cream for refining hot meals.
It is another object of the present invention that the cream substitute fulfill the functions of cream as to its whitening power, sensation in the mouth, and taste.
It is still a further object of the present invention to provide a cream substitute that is readily dispersible and easy to handle.
It is still a further object of the present invention to provide a cream substitute that does not have a thickening effect on the consistency of the food product to which it is added.
SUMMARY OF THE INVENTION
The foregoing objectives are met by a formed cream substitute for the addition to hot meals, which, according to the invention, comprises cream powder and fat powder in a matrix of pure fat. The cream substitute contains from 20% to 60% cream powder, from 10% to 50% fat powder, and from 15% to 50% of fat matrix. A fat powder on the basis of whey protein is used, which contains at least 50% of fat. The cream substitute can be provided in the form of lumps, in the form of cubes, or in the form of a granulate.
For the preparation of a lumpy cream substitute, a mixture of cream powder and fat powder is mixed in a molten fat mixture which, after cooling to an extrudable mass, is molded into single portions. For the preparation of small cubes, a batch of 30 to 55% of spray dried cream powder, 10 to 40% of spray dried fat powder and 20 to 40% of fat matrix is used.
For the preparation of a cream substitute in the form of a granulate, 30 to 60% cream powder, 10 to 40% fat powder, and 25 to 50% fat are mixed at 40-50° C. (104-122° F.) to a flowable dough and this dough is grated after cooling. As an alternative, cream powder, fat powder, and fat in the form of flakes can be homogeneously mixed and the mixture may be granulated. The heat dispersibility of the granulate, as well as of the cubes, can be improved by the addition of a small amount of lecithin in the form of a powder.
It can be of advantage to add a small amount of carbohydrate material, such as, for example, maltodextrin or starch, as a diluting agent for the fat-containing constituents of the recipe. To prevent flocculation, a small amount of a 1:1 mixture consisting of tetrasodium pyrophosphate and disodium dihydrogen diphosphate can be added to the cream substitute.
DETAILED DESCRIPTION
According to the invention, the set task is solved by a formed cream substitute which can be added to hot meals and which consists of cream powder and fat powder in a matrix of pure fat is provided.
The cream substitute according to the invention can be provided in the form of lumps, in the form of cubes, or in the form of a granulate.
Cream powder is a well-known and commercially available product. It is prepared from cream or from a mixture of milk and cream and contains at least 42% of fat and at most 5% of water. A cream powder having a fat content of 55% was not optimal as regards whitening power and ropiness. A cream powder preferred for the purposes of the present invention contains at least 45%, preferably at least 75% of fat. Usually it is produced by spray drying.
Fat powder is also a commercially available product. It is prepared from a homogenized emulsion, usually by spray drying. A basis consisting of, for example, caseinate or whey protein is used for pulverization. Fat powders preferred in the present invention contain at least 50%, preferably at least 60%, of fat. A suitable fat powder is, for example, a highly fatty powder containing 75% of fat on the basis of caseinate.
Fat powders on the basis of caseinate, however, have the disadvantage that they are unstable in the presence of an acid medium at pH values of less than 5.5. The product then flocculates. This disadvantage does not occur in fat powders in which the protein basis consists of whey protein. Those fat powders are resistant to acids. Such commercial fat powders, however, occasionally have only a low fat content, of only 15%, for example. Such fat powders are less suitable for the present invention, because due to the low fat content, the whitening power is limited. It is also possible, however, to prepare fat powders on the basis of whey protein which have a higher fat content, such as at least 50%, preferably at least 60%, for example 65%, which are then provided with sufficient whitening power and are excellently suited for the purposes of the present invention. Using such fat powders, it is possible to prepare a cream substitute according to the invention which does not flocculate even in an extremely acid medium.
According to the invention, the cream powder and the, fat powder are worked in a matrix of pure fat. The person skilled in the art will not have difficulties in selecting a fat suitable for that purpose taking into account the melting points. Suitable fats include butter fat and hardened and unhardened vegetable fats, such as, for example, palm oil, all of which can be used in mixture.
A cream substitute according to the invention in general consists of 20 to 60% of cream powder, 10 to 50% of fat powder and 15 to 50% of fat matrix (all percentages are percent by weight).
For the preparation of the cream substitute according to the invention in the form of lumps, a mixture of cream powder and fat powder is mixed in a molten fat mixture, which, after cooling to an extrudable mass, can be formed into single portions by usual molding machines.
For the preparation of small cubes, preferably, a batch of 30 to 55%, in particular 30 to 35%, of spray dried cream powder, 10 to 40%, in particular 30 to 35%, of spray dried fat powder and 20 to 40%, in particular 30 to 40%, of fat matrix is used.
The cream substitute according to the invention can be portioned into lumps, for example into the form of small cubes having a weight of 5 to 10 g (0.18 to 0.35 ounces). While the cube is the form suitable for refining small quantities of food, it is less favorable in the field of large-scale catering establishments. In catering establishments, many small cubes would have to be unwrapped, while a very large cube would be difficult to dissolve. Therefore in the field of large scale catering establishments, a flowable granulate which can be dosed freely is preferred.
A cream substitute according to the invention in the form of a granulate can be prepared by mixing 20 to 60% of cream powder, 10 to 40% of fat powder and 25 to 50% of fat at 40 to 50° C. (104 to
