Description

TITLE OF THE INVENTION
FROZEN SLUSH SNACK COMPOSITIONS BACKGROUND OF THE INVENTION Field of the Invention:
The present invention relates to frozen slush snack compositions. In particular, the present invention relates to alcohol-free frozen slush snack compositions, which are liquid at room temperature and exist as a slush at temperatures of -10°F to +10°F.
Discussion of the Background:
Flavored slush snacks are popular, especially with children in the six to twelve year old age group. Such snacks are usually only consumed at or near the place of production, and are typically prepared by a scraped-surface freezer. These snacks are prepared on a continuous basis with constant agitation typically during freezing. Such flavored slush snacks are composed of a sweetened and flavored aqueous liquid containing fine ice crystals and are served at or near the freezing point of water. Such flavor slush snacks are not usually prepared in the home because of the specialized equipment required. As a further disadvantage, when such snacks are melted, re-freezing of the product provides an undesirable product which is essentially a block of ice. _ An overview of the properties desired for and the problems encountered with such frozen slush snacks is provided in U.S. Patent no. 4,808,428, which is incorporated herein by reference. Specifically, a number of problems are encountered in preparing a flavored liquid snack product which is intended to be marketed in containers stored at room temperature for subsequent use by the household by placing the container in a home freezer. The first problem is one of sweetness regulation. In most compositions of this nature, the presence of a high level of sugar is desired to modify the extent and type of ice crystal formation sufficiently to permit the realization of a slush rather than a solid frozen product. Slush is defined as a mixture of liquid and ice crystals. Thus, the selection of a suitable sugar or combination of sugars which will supply the desired ice crystal modification effect and freezing point depression and at the same time not be unbearably sweet to the taste is important.
A second and related problem is that of crystallization of dextrose or other sugars used in preparing these products. Because of the concentration effect which takes place on freezing of liquids of this nature, sugars such as dextrose reach a point where they are in supersaturated solution, whereupon crystallization of the sugar takes place. The crystals do not readily re-dissolve on thawing of the product. The presence of crystallized dextrose and other sugars is decidedly a disadvantage in slush snacks in that the white crystals provide an unattractive, undesirable, appearance to the frozen product. This problem of crystallization is accentuated where repeated freeze-thaw cycles are encountered. Another important consideration is the shelf stability of the liquid product at room temperature. Liquids having a high sugar content are ideal places for microorganisms such as yeast to grow. It is thus important that microbiological stability is insured by using the correct balance of sugar concentration, acidity and added preservatives such as the sorbates and benzoates.
Still another important consideration is the nature of the final product. It is desirable to provide a product which has a substantial proportion of platelet ice crystals, termed "shale" ice, intermixed with liquid and fine ice crystals to form a homogeneous mass. This homogeneous mass must form during quiescent freezing of the product in the container. At the same time, the frozen product must be easily disrupted by stirring or by pressure exerted by deforming a flexible container.
Another important consideration is that the consistency of the slush product remain substantially unchanged over a prolonged period of storage at freezer temperatures. Home freezer temperatures vary from +10°F to -10°C and the product must be formulated so that the product is readily stirred to a slush with a spoon after two to three months storage at -10°F. Still another important consideration is the character of the slush snack after removal from the freezer and during consumption. It is highly desirable that immediately upon removal from the freezer, the product can be simply stirred with a spoon to break it up into a slush which is readily consumable with a spoon. During melting of the slush, which should take place over a period of about 15-20 minutes at room temperature, desirable slush characteristics should be maintained. The completely melted product should also be suitable for drinking, should be free from gummy or slimy characteristics and should have a consistency approaching that of water.
U.S. Patent No. 3,647,472 describes a beverage mix which can be stored at room temperature for an indefinite period of time but which is intended to be placed in a home freezer to be allowed to freeze to a slush consistency before it is consumed. The beverage mix is intended to be combined with an alcoholic distillate or other liquid ingredient before consumption. The composition contains sugar in quantities up to 30-40% by weight, which serves as both a sweetener and as a cryoscopic modifier. Glycerol is also used as a cryoscopic modifier, for the purpose of controlling the size of the ice crystals and the freezing point of the mix.
One disadvantage of the product disclosed in U.S. Patent No. 3,647,472 is the requirement that it be mixed with another liquid, such as an alcoholic distillate or other beverage, before consumption. In addition, the patented product contains glycerol at a level of 0.5 to 8% to control the size of the ice crystals formed during freezing. It has been found that glycerol contributes an undesirable bitter flavor to the product.
U.S. Patent No. 3,826,829 describes a liquid suitable for producing a slush beverage which utilizes a composition containing water, sugars, polyols, flavor, and coloring agents together with pectin in combination with other gums as a stabilizing agent. The product of this invention, which can include both carbonated and non-carbonated aqueous solutions as a base, has for an object the provision of a product having a sherbet-like consistency. This fine grained ice crystal structure is a disadvantage where products containing "shale" ice crystals are desired. In addition, high levels of pectin are known to impart an unpleasant, somewhat slimy characteristic to the beverage when the product has melted and also contributes to haziness in the product, which can be unacceptable for purposes where clarity is desired. Moreover, the products described in U.S. Patent No. 3,826,829 contain a polyol, such as propylene glycol, sorbitol, and glycerol, as an essential ingredient. Such polyols contribute an undesirable bitter flavor to the product, exhibit a laxative effect on some people, and are undesirable from a labeling standpoint.
U.S. Patent No. 3,897,571 describes a process for producing a refrigeration-stable slushed comestible concentrate that is spoonable and stirrable at 0°F, and which remains in this desirable condition over an extended period of storage at home freezer temperatures, without hardening into an unspoonable block. The process includes the steps of slowly growing ice crystals in a composition containing gum and sugar and continuing the crystallization process while agitating to produce an overrun and to incorporate a gaseous phase to establish a stable tertiary phase mixture of concentrates syrup matrix interspersed with coarse ice crystals in a gaseous foam. A product of this type has the disadvantage of requiring distribution and storage only under home freezer temperatures. In addition, it does not retain its desirable characteristics through a thaw-refreeze cycle.
U.S. Patent No. 3,922,361 describes a process for preparing a soft frozen, all natural fruit juice in which a fruit juice concentrate, such as orange, is thawed and combined with natural sweeteners and subjected to freezing in a slush freezing apparatus. A drawback of the product produced in U.S. Patent No. 3,922,361 is that preparation of the final product must be carried out in a commercial soft frozen freezer machine, not a conventional home freezer.
U.S. Patent No. 4,724,153 discloses a soft-frozen water- ice formulation which is extrudable at 0° to 10°F and which contains a critical amount of chemical emulsifiers. One disadvantage of the product disclosed in U.S. Patent No. 4,724,153 is that the product requires processing with freezing equipment not suitable for home use. The product also requires the use of polysorbate 80, which must be listed specifically on the product label. It is undesirable on a label because it does not sound "natural and healthy." Polysorbates are also not permitted for food use in some countries, and thus their presence would limit export possibilities if so desired.
U.S. Patent No. 4,790,999 discloses a ready-to-consume, freezable alcoholic beverage composed of water, sugars, alcohol, flavorants, and carboxymethyl cellulose. The presence of alcohol renders these compositions inappropriate for consumption by children.
U.S. Patent No. 4,808,428 discloses a flavored slush snack composed of 22-33% dextrose, 1-5% fructose, an edible acid preservative, and water. One disadvantage of the product disclosed in U.S. Patent No. 4,808,428 is that it requires either high levels of dextrose, which are excessively sweet, or the addition of sorbitol, which can have an undesirable laxative effect.
U.S. Patent No. 4,971,824 discloses a frozen natural food product formed solely from all natural fruit, vegetable juices, purees or combinations thereof. One disadvantage of the product disclosed in U.S. Patent No. 4,971,824 is that the product requires processing with freezing equipment not suitable for home use. It also contains only fruit juices and therefore does not allow for the creation of nonfruit flavored products, like chocolate or caramel.
U.S. Patent No. 4,986,994 discloses a process for preparing a low calorie slush beverage in which an artificial sweetener is completely dissolved in water, followed by the addition of microcrystalline cellulose, followed by the addition of xanthan gum which has been wetted with propylene glycol. However, this process requires a freezing chamber not suitable for home use.
U.S. Patent No. 5,246,725 discloses a spoonable frozen food product which contains a fairly high concentration (3 to 10% by weight) of a bulking agent, such as maltodextrin, corn syrup solids, polydextrose, xanthan gums, locust bean gum or CMC. One disadvantage of the product disclosed in U.S. Patent No. 5,246,725 is that the products contain only nonnutritive sweeteners, which have objectionable flavors or aftertastes for many people, along with various reported undesirable side effects.
Thus, none of the products described in the prior art are completely satisfactory. Accordingly, there remains a need for frozen slush snack compositions.
SUMMARY OF THE INVENTION Accordingly, it is one object of the present invention to provide novel frozen slush snack compositions.

(b) 0.15 to 0.9 wt.% of pectin;
(c) 13 to 37 wt.% of sugar; and
(d) 60 to 87 wt.% of water.
Pectin is a polysaccharide substance of molecular weight 20,000-400,000 derived from the cell walls of plants, which is commercially available from, e.g. , Sigma Chemical Company, St. Louis, MO; Danisco Ingredients USA, Inc., New Century, Kansas; and Pectagel Inc., Great Neck, New York.

If the composition is to be stored in the liquid state for only a short period of time, no special precautions need be taken to exclude bacteria. On the other hand, if the composition will be stored in the liquid state for a long period of time, it is preferred that precautions be taken to exclude bacteria and/or that the composition contain a preservative, such as described above. For example, the composition may be prepared under aseptic conditions by adding the dry ingredients to water heated to 180°C and then aseptically transferring the product to a sealed container.
The present composition may then be packaged in an air¬ tight package. Suitable packages include sealed foil pouches or bags, plastic cups with air-tight covers, etc. The packaged composition will typically be stocked and sold at room temperature (i.e., in the liquid state). The consumer will then place the packaged composition in their freezer. Typically, the slush is formed within a few hours. The slush is formed with quiescent cooling, i.e., without agitation. After the slush has formed, the composition is removed from the freezer and is consumed. In some cases, it may be preferred to "soften" the slush by either gentle manipulation of the package or stirring with a straw or spoon.
At home, the composition may be stored either in the frozen state in the freezer or in the liquid state in a cupboard or pantry. The present compositions are storage stable for long periods of time in either the slushy or liquid state and are stable to repeated freeze/thaw cycles. Other features of the invention will become apparent in the course of the following descriptions of exemplary embodiments which are given for illustration of the invention and are not intended to be limiting thereof.
