This invention relates generally to confection toppings for application to frozen desserts, and to methods for their manufacture.

Toppings of the confection type that are applied to frozen desserts are generally of liquid or semi-liquid consistency with a substantial moisture content (e.g., 20 to 30%) and consisting mainly of sugar syrup together with flavoring material such as chocolate or fruit solids and/or juices. Such compositions may have an oil (i.e., fat) content for providing a rich flavor, as for example, a content of the order of 5 to 10%. When applied to frozen desserts like ice cream, the topping may become more viscous at the lower temperatures to which it is chilled, but it remains essentially in liquid or plastic condition.

Confection compositions have been used for coating or enrobing frozen desserts, as for example compositions containing chocolate and sugar. Such compositions are specifically formulated to get a rapid, dry coating and are applied at temperatures of about 95° F. This requires keeping the coating composition in melted form at about 95° F. The coating hardens and dries in a few seconds upon contact with the frozen confection and permits wrapping in a continuous packaging line.

In general, it is an object of the present invention to provide a confection topping in fluid form which when applied at room temperature to frozen desserts like ice cream immediately hardens to form a brittle edible shell.

Another object of the invention is to provide such a topping which is relatively stable at room temperature, and which is of such consistency that it may be either poured upon the frozen dessert, or the dessert dipped in the composition.

Another object is to provide a topping which is very low in moisture content, high in fat content, and which after hardening is characterized by absence of graininess.

Another object is to provide a topping formulation which can be made in a variety of flavors.

Another object is to provide a method for commercial manufacture of the composition, and particularly a method which is economical and does not involve undue processing time.

In general, the product is a homogeneous blend that is fluid at room temperature. It contains a relatively high high oil or fat content (e.g., 44 to 53%), and a sugar content of from 28 to 38%. Preferably it contains some milk solids, and corn syrup solids, and various flavoring materials (e.g., cocoa) can be added. In addition it contains from 1.8 to 2.4% of hard crystallized emulsifiers having melting points of about 140° to 145° F. and stearine dispersed in a refined vegetable oil, together with additional flavoring ingredients and color that may be desired. Mainly by virtue of heat exchange between the mix from step 12 and the ingredients added in step 13, this further reduces the temperature of the mix to about 85° to 90° F. The mix is blended and milled in step 13 by use of suitable blending and milling equipment. Milling results in some increase in temperature (e.g., 10 to 15% F.) but does not increase the temperature above a maximum of 100° F. This temperature limitation is assured by having the mix at a temperature of about 85° to 90° F. at the time milling is commenced, and is below the melting temperatures of the crystallized emulsifier and fat contained in the emulsifier and stearine dispersion. The product is then ready for filling containers.

As a suitable emulsifier, we have employed mono and diglycerides having melting points as high as 140° F. to 145° F. and in the form of relatively fine micro-crystals. The crystallized emulsifier is and stearine are dispersed in a suitable vegetable oil for introduction in step 13, such as an oil that is 95% liquid at 70° F., thereby facilitating blending with the other ingredients and maintaining the emulsifier and stearine in solid micro-crystalline form. After blending and milling in step 13 the resulting fluid product is immediately suitable for packaging and use. In other words, no ageing is required to attain stabilization.

Blending in steps 12 and 13 can be carried out by the use of conventional blending equipment. Milling after blending in step 13 serves to break up crystal agglomerates and to impart smoothness to the product and may be carried out by a colloid type of mill.

Instead of introducing all of the hard crystalline emulsifier in step 10, a small amount, such as from 0.2 to 0.3%, may be introduced in step 10 before heating. Heating to a temperature of about 165° F. serves to melt such emulsifier, although it recrystallizes later in the process when the blend is chilled.

The vegetable oil or fats selected for use in the process are such that the final product is fluid at ambient room temperature above about 65° F. with a limited amount of fat in crystalline form. The oils should be bland with respect to flavor, be odorless, and be relatively stable. The elevated temperature in step 10 ensures homogeneous blending and in addition provides for pasteurization and elimination of any bacterial contamination. Chilling in steps 11 and 12 to a lower temperature level prevents dissolution of the crystalline emulsifier material introduced in step 13, which would occur at the higher temperature level of the material. Also this lowered temperature level together with further lowering of the temperature when the additional ingredients are added in step 13, assures a temperature level of the final milled product that does not exceed the maximum of about 100° F. The emulsifier and stearine introduced in step 13 remains in crystalline form, with only a minimum amount of dissolution.

The milk solids employed may be nonfat spray dried milk or spray dried whey solids. When whey solids are employed, we prefer to use a whey protein concentrate with at least 35% protein and with reduced mineral content to minimize salty flavor. Such whey products are disclosed in U.S. Pat. Nos. 3,615,664 dated Oct. 26, 1971 and 3,447,930 dated June 3, 1969. Blends of whey and nonfat milk solids can also be used.

The sugar content should be powdered sucrose, such as is used by confectioners, or a blend of powdered sugar and corn sugar or dextrose.

The composition of the product except for peanut butter may be as follows:

______________________________________

Vegetable oil 44 to 53 46 to 51
Sugar (powdered sucrose)

Composition for peanut butter is given in Example 2.

The product produced by the process remains fluid at ambient temperatures above 65° F., and it can be stored for long periods of time without deterioration. When it is applied to a frozen dessert, as for example to a scoop of ice cream on a cone or to a dish of ice cream, it instantly hardens and forms a brittle edible shell. Hardening occurs at such a rapid rate that there is substantially no drippage or run-down of the topping about the sides of the cone.

According to our observations, the rapid hardening of the topping is due to the seeding effect of the crystallized emulsifier and stearine present in the product. In other words, when the composition is chilled to a temperature below about 32° F., crystallization of fat is seeded whereby the composition is converted almost instantly from a fluid to a brittle solid state.

Examples of the invention are as follows:

The vegetable oils supplied to the blending step 10 comprised a bland refined hydrogenated vegetable oil which was fluid at room temperature and which was odorless and relatively stable. More specifically, one part of the oil employed was a product manufactured by the Glidden-Durkee Division of S.C.M. Corporation, known by the trade name of "Durkex 500". Its solid fat content at 70° F. was about 3 to 5%. The other part of the oil content supplied to step 10 was a refined coconut oil likewise manufactured by the Glidden-Durkee Division of S.C.M. Corporation and sold under the trade name of "Konut 76". This oil is liquid at a temperature above about 76° F. It has a low degree of unsaturation and a relatively narrow melting range. Also it has a bland sweet flavor. The milk solids employed were nonfat dry milk. The sugar was powdered sugar (sucrose), such as is used in the confection industry. The corn syrup solids was a 24 D.E. product. The additive used for flavoring was cocoa. The crystallized emulsifier was and stearine were dispersed in the oil and was procured from the Glidden-Durkee Division of S.C.M. Corporation, being known by the trade designation of "Durkee B-4A Fluid Shortening". This product comprised 6% of microcrystalline hard fat, namely stearine having a melting point of from 135° to 155° F., and 4% microcrystalline mono and diglyceride emulsifiers having melting points of from 140° to 145° F., dispersed in 90% refined vegetable oil, namely soya oil. The emulsifier was hard mono and diglycerides. Ten percent of the emulsifier and stearine was dispersed in the oil, and the oil was a refined vegetable oil (namely soya oil) containing about 3% solid fat at 70° F. The Dur-Em 117 emulsifier is similar to that dispersed in the B-4A. The proportioning of the ingredients was as follows:

The procedure was generally the same as described with reference to FIG. 1. The vegetable oils, nonfat milk solids, corn syrup solids, cocoa and lecithin were blended, heated to a temperature of about 165° F., and held at that temperature for a period of 5 minutes to ensure pasteurization. This mix was then promptly chilled to a temperature of about 100° to 115° F. The sugar was then added, which further reduced the temperature to about 90° to 100° F. This mix was then blended with oil in which the microcrystalline emulsifier was and stearine were dispersed, together with the flavoring ingredients, with further reduction of the temperature to about 85° to 90° F. Milling the mix produced the final product and caused a temperature rise limited to a maximum of about 100° F.

Peanut butter was as a flavoring ingredient. The basic ingredients and the manufacturing procedure was essentially the same as for chocolate. The natural peanut butter was introduced with the B-4A shortening. The proportion of the ingredients was as follows:
