Description

[0001] This application claims the benefit of the filing date under 35 U.S.C. § 119(e) of U.S. Provisional Application No. 60/086,561, filed May 21, 1998 which is hereby incorporated by reference.

BACKGROUND OF THE INVENTION

[0002] The present invention is directed to a shelf-stable cookie dough confection, a product comprising the shelf-stable cookie dough confection packaged in a sanitary package, an apparatus for metering and dispensing a compressible confection, and a process for packaging the compressible confection.

[0003] Traditionally, raw cookie dough was merely the intermediate product of the desired product, the baked cookie. Cookies were either made at home, or were baked and packaged for distribution. In recent years, raw cookie dough has been packaged and distributed as such, to be formed into cookies and baked at home. The cookie itself has somewhat bowed in popularity to the rich, sweet and creamy texture of conventional raw cookie dough. Conventional raw cookie dough and products containing raw cookie dough, such as cookie dough ice-cream, have become increasingly popular. Typically, these products include real eggs and flour. To decrease the danger in eating these products, egg substitutes often replace eggs. However, even with the omission of real eggs, a danger remains under moist conditions as the flour and the proteins therein provide a harbor for bacteria. To prevent microbial growth, conventional raw cookie dough and products containing raw cookie dough require refrigeration and, as such, are not shelf-stable. A shelf-stable cookie dough would therefore be of great importance.

[0004] Conventional raw cookie-dough has traditionally been packaged in what is known in the art as a chub-pack. The chub-pack, typically, comprises a thin plastic casing in the form of a tube encasing the cookie dough. Each end of the plastic casing is clinched with a metal band. Despite the bands, when not refrigerated the fat in the product can wick out of the clinched ends, resulting in exposure to air, moisture and contamination. A shelf-stable cookie dough product comprising a shelf-stable cookie dough confection packaged in a sanitary package would therefore be a great improvement.

[0005] Once a shelf-stable cookie dough confection was invented in accordance with the present invention, it was found to be compressible. In packaging processes, a compressible confection exhibits compression and relaxation phenomena. More specifically, the compression and relaxation phenomena occur when a compressible confection is initially forced to move through a process line. For example, because air cells are incorporated in an aerated fat used in the confection, the material initially does not move when pressure is applied. In fact, movement only occurs once the confection builds up a head pressure sufficient to overcome the flexing, or compressing, air cells. This is known as the compression phenomenon. Once the confection is moving, the majority of the pressure is stored in the furthest back portion of the confection in the line where pressure originated. Upon relieving the pressure to stop the flow, the partially compressed confection returns to its original form and the confection springs forward to equalize the pressure. This is known as the relaxation phenomenon. Thus, if the product is packaged using an intermittent flow system and a finite number of units per minute to fill the packaged product, the confection will not fill on immediate command due to the compression phenomenon, nor will the flow of the confection shut off on immediate command due to the relaxation phenomenon. These phenomena lead to inconsistent flow, or weight control, of the compressible confection in the final packaged product. Thus, a compressible confection requires unconventional pumping equipment for even flow, or weight control, of the final product. An apparatus and process for metering and dispensing a compressible confection capable of overcoming the compression and relaxation phenomena would be a significant contribution to the art of confection packaging.

SUMMARY OF THE INVENTION

[0006] As noted above, a confection has been invented which has a taste and texture of raw cookie dough, but which is shelf-stable. In one aspect, the present invention is such a shelf-stable confection itself

[0007] In another aspect, the invention is a product comprising a shelf-stable confection having the taste and texture of raw cookie dough in a package, preferably a sanitary package of an individual portion of the confection.

[0008] In yet another aspect, the invention is an apparatus for metering and dispensing a compressible confection comprising at least one metering pump, the metering pump comprising an intake port and a discharge port, at least one internal bottom shutoff nozzle, at least one product line interconnecting the metering pump and the internal bottom shutoff nozzle, and a control mechanism for cyclically operating the at least one metering pump and operating the at least one internal bottom shutoff nozzle in synchronization with the metering pump such that generally constant pressure is maintained between the metering pump and the internal bottom shutoff nozzle.

[0009] In a further aspect, the invention is a process for packaging a shelf-stable confection having the taste and texture of raw cookie dough comprising the steps of loading at least one empty cup onto a packaging conveyor, conveying the at least one empty cup to a filling station, filling the at least one empty cup with the confection to form at least one filled cup, conveying the filled cup to a lid placement station, placing a lid on top of the filled cup, conveying the filled cup to a lid sealing station, and sealing the lid to the filled cup to form a packaged product.

[0010] The shelf-stable cookie dough confection itself confers an improvement over the prior art in that it requires no refrigeration. In addition, the shelf-stable cookie dough product satisfies a need unmet by the prior art for a sanitary package containing a shelf-stable cookie dough confection that protects the confection from exposure to air, moisture and contamination at room temperature. Yet another improvement over the prior art conferred by the present invention is an apparatus and process for metering and dispensing a compressible confection which is capable of overcoming the compression and relaxation phenomena exhibited in conventional processes for packaging compressible confections. These and other advantages of the invention, as well as the invention itself, will be best understood in view of the attached drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] The present invention includes aspects drawn to a shelf-stable cookie dough product 20, as depicted in FIGS. 3 and 4, an apparatus for metering and dispensing a compressible confection 22, as depicted in FIGS. 1, 2, 5, 6, 7, 8, 9 and 10, and a process of packaging the compressible confection 10 as depicted in FIG. 1.

[0022] The shelf-stable cookie dough product 20 includes a shelf-stable cookie dough confection 22. The shelf-stable cookie dough confection 22 has a taste and texture of raw cookie dough. The confection can be made using an aerated fat, a food grade glycerine, a food grade starch and sugar.

[0023] The taste and texture of the confection is selected from, but not limited to, the group consisting of chocolate chip cookie dough flavor, peanut butter cookie dough flavor, chocolate peanut butter cookie dough flavor, sugar cookie dough flavor, chocolate cream sandwich cookie flavor, cookie and cream flavor, chocolate mint chip flavor and chocolate brownie flavor.

[0024] The aerated fat provides a light, fluffy, or doughy, texture to the confection. The aerated fat is selected from the group consisting of, but is not limited to, shortening-type fats. The preferred confection has an aerated fat composition between about 10 and 45 weight percent.

[0025] The food grade glycerine provides plasticity to the confection. Preferably, the glycerine has a percent solids level of between about 96 to about 99 percent solids. The preferred composition comprises between about 0.5 and about 10 weight percent of a food grade glycerine having a solids level of about 96 weight percent solids.

[0026] The food grade starch acts both as a drying agent and a bulking agent. As a desiccant, starch provides additional moisture protection. As a bulking agent, starch eliminates the need to use flour, a bulking agent used in conventional cookie dough confections. Flour, and the proteins found therein, typically provide a harbor for bacteria. Thus, the use of starch as a bulking agent and the attendant reduced risk of bacterial contamination confers an advantage to the relevant art. The preferred composition comprises between about 5 and about 30 weight percent of a food grade starch.

[0027] The sugar is selected from the group consisting of brown sugar, brown sugar powder, granular sugar, powder sugar and mixtures thereof. The preferred composition comprises between about 5 and about 45 weight percent sugar. More preferably, the confection comprise between about 5 and about 30 weight percent brown sugar powder, between about 5 and about 30 weight percent granular sugar, and between about 5 and about 30 weight percent powder sugar.

[0028] The preferred confection includes a food grade emulsifier. The emulsifier acts as a binding agent and is added in either a dry or a melted form. As a binding agent, the food grade emulsifier brings together the fat portions of the confection with any available moisture and provides stability to the overall confection. More specifically, the food grade emulsifier provides a dough-like texture and prevents the confection from crumbling and falling apart over time. Preferably the food grade emulsifier is selected from a group consisting of mono- and di-glycerides and propylene glycol. Most preferably the food grade emulsifier is MIVATEX 3-50. The preferred composition comprises between about 0.1 and 2 weight percent of a food grade emulsifier.

[0029] The preferred confection includes a food grade antioxidant. The antioxidant is added to prevent oxidative rancidity and to improve the shelf life. Typically, a shelf life of about nine to 12 months can be achieved. The antioxidant is added in compliance of governmental regulations as a percentage of the fat. The preferred composition comprises a food grade antioxidant at a level of about 0.02 percent by weight of the fat.

[0030] The preferred confection includes corn syrup solids. The preferred composition comprises between about 5 and about 30 weight percent corn syrup solids.

[0031] The preferred confection includes a flavoring. The flavoring is selected from, but not limited to, the group consisting of vanilla, almond, peanut butter, chocolate, mint and combinations thereof The preferred composition comprises between about 0.05 and about 3.5 weight percent of a flavoring.

[0032] The preferred confection includes a flavored chip. The flavored chip is selected from, but not limited to, the group consisting of chocolate, peanut butter, mint, chocolate cookie, vanilla cookie, mint cookie, and brownie. Preferably, the flavored chips are fat-based. Most preferably, the fat-based flavored chips are coated. The coating prevents the fat-based flavored chips from dissolving in the confection. The preferred composition comprises a flavored chip content of between about 0.1 and about 20 weight percent.

[0033] The preferred confection includes a stabilizer such as a cellulose-based gum. The stabilizer is added to create a creamy, doughy texture. Most preferably, the cellulose-based gum comprises hydroxypropyl methylcellulose. The preferred composition comprises between about 0.5 and about 4 weight percent of a cellulose-based gum.

[0034] The preferred confection includes a food grade salt. The preferred composition comprises between about 0.1 and 4 weight percent of a food grade salt.

[0035] The confection of the present invention is virtually moisture-free. As such, microbial growth is inhibited. The preferred confection has a water activity (Aw) level of 0.6 or less.

[0036] An example of a cookie dough confection of the preferred invention has a water activity (Aw) level of 0.6 or less and comprises about 28 weight percent of an aerated fat, about 1 weight percent of a food grade glycerine, about 0.5 weight percent of a food grade emulsifier, about 0.25 weight percent flavoring, about 0.0056 weight percent of a food grade antioxidant, about 14.75 weight percent of a food grade starch, about 13 weight percent brown sugar powder, about 12.64 weight percent granular sugar, about 10 weight percent corn syrup solids, about 9.0 weight percent powder sugar, about 7.75 weight percent chocolate flavored chips, and about 2 weight percent cellulose-based gum.

[0037] FIGS. 3 and 4 illustrate another aspect of the invention. The shelf-stable cookie dough confection product 20 comprises a shelf-stable cookie dough confection 22 in a package, preferably a sanitary package of an individual portion of the confection. The sanitary package provides a barrier to oxygen and moisture and preferably includes a cup 24, a sanitary disk 26, an eating implement 28, and a lid 30.

[0038] Most preferably the cup 24 comprises a multi-layer laminate of polystyrene, ethylvinyl alcohol and polyethylene. The eating implement 28 is choke resistant and is preferably a spoon. Most preferably the spoon has a 2½ inch length. The ideal length of 2½ inches makes the spoon small enough to fit within the cup but large enough to avoid the danger of becoming lodged in the throat of a small child. Thus, the incorporation of an eating element 28 within the packaging of the shelf-stable cookie dough confection product 20 represents a unique aspect of the present invention.

[0039] The sanitary disk 26 is placed between the shelf-stable cookie dough confection 22 and the eating implement 28. Most preferably the sanitary disk 26 is impervious to fat and comprises a foam material.
