ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is broadly concerned with confections, and methods of forming these. More particularly, the confections are dehydrated marshmallow-like products formed from a mixture comprising sugar, water, and a protein preferably selected from the group consisting of egg albumen, whey protein, and soy protein. The methods of forming the products comprise forming a mixture of the ingredients, creating the desired shapes from the mixture, and drying the mixture so as to yield the chemically expanded marshmallow products. The inventive marshmallow products have a relatively low density and are essentially gelatin free.
2. Description of the Prior Art
Dehydrated marshmallow pieces have been used in children's cereals for a number of years. These marshmallows have generally been formed by creating and coloring a slurry including water, sugar, and gelatin, whipping the slurry so as to produce an aerated product, extruding the product at a water content of 10-16% by weight, and cutting the product to the desired size and shape. The cut product is then air-dried to a final moisture content of about 1.5-2.5% by weight.
There are numerous shortcomings in the currently available marshmallow products and processes for forming those products. For example, during the cutting of the marshmallow product a significant quantity of starch (as high as 20% by weight) must be utilized to prevent sticking or caking of the product and to improve the product flow. The starch must then be removed prior to sale, with the starch removal being a messy process which increases the overall expense involved.
Another problem with prior art marshmallows is that they have a limited cereal bowl life. Over time, all marshmallow products begin to react with the milk in the bowl, resulting in a soggy marshmallow. Many currently available dehydrated marshmallow products almost completely disintegrate after about thirty seconds in milk. Cereal manufacturers are continually seeking dehydrated marshmallows which retain their initial integrity in milk for longer periods of time, so as to allow the cereal eater to consume essentially the entire bowl of cereal before the marshmallows disintegrate.
Yet another problem with currently available marshmallows is that they contain gelatin, thus making them non-kosher. This prevents an appreciable number of potential consumers from purchasing products containing these marshmallows. Additionally, because the marshmallow products aren't kosher, any equipment that produces these marshmallows or products incorporating these marshmallows, is also non-kosher. This can lead to downtime and added expense for manufacturers who need kosher equipment.
Finally, the currently available processes for forming dehydrated marshmallow products are limited to products having simple two-dimensional shapes (e.g., hearts, moons, rainbows). There are no processes for forming dehydrated marshmallows having intricate three-dimensional shapes which would be appealing to many consumers.
SUMMARY OF THE INVENTION
The instant invention addresses the foregoing problems by providing kosher dehydrated marshmallow products which have an improved bowl life and can readily be formed into a wide variety of shapes.
In more detail, the moldable, expanded confections or dehydrated marshmallows of the invention are formed from a mixture comprising sugar, water, and a protein. The sugar is preferably present in the mixture at a level of from about 69-80% by weight, and preferably 71-76% by weight, based upon the total weight of the mixture taken as 100% by weight. There should also be sufficient water present in the mixture so that the total mixture moisture content is from about 6-12% by weight, and preferably from about 7-9% by weight, based upon the total weight of the mixture taken as 100% by weight.
Examples of preferred proteins for use in the marshmallows are those selected from the group consisting of egg albumen, soy protein, whey protein, and mixtures thereof The total protein present in the mixture is preferably at least about 4% by weight, and preferably from about 5-10% by weight, based upon the total weight of the mixture taken as 100% by weight. Also, unlike prior art marshmallow products, the inventive marshmallows do not require gelatin and are, therefore, essentially gelatin free. As used herein, “essentially gelatin free” means that the products contain less than about 0.05% by weight gelatin, preferably less than about 0.02% by weight gelatin, and more preferably 0% by weight gelatin, based upon the total weight of the mixture taken as 100% by weight.
In one embodiment, it is preferred that the marshmallow products further comprise compounds which provide controlled chemical gassing for expanding the marshmallows. This eliminates the problems of prior art mechanical expansion methods which cannot be easily controlled, and which utilize equipment requiring regular maintenance. The most preferred gassing compounds are sodium bicarbonate and monocalcium phosphate. In a preferred embodiment both sodium bicarbonate and monocalcium phosphate are present in the mixture at a level of from about 0.4-0.6% by weight and from about 0.6-0.8% by weight, respectively, based upon the total weight of the mixture taken as 100% by weight. In some applications, a small amount of sodium aluminum phosphate (e.g., less than about 0.1% by weight) may be added in order to promote even gassing of the product.
There are numerous other optional ingredients which are preferably included in the marshmallow products. For example, it is desirable to include a filler of some type, with flour being a preferred filler. The filler is useful for reducing the stickiness of the mixture. In order to ensure maximum sweetness of the product, the level of filler in the mixture should be less than about 20% by weight, and preferably from about 5-10% by weight, based upon the total weight of the mixture taken as 100% by weight.
Other optional ingredients that can be utilized include flavoring agents, preservatives, coloring agents, and nutritional supplements (e.g., vitamin supplements and/or mineral supplements such as calcium). Any known flavoring agent can be utilized, with marshmallow flavoring and orange flavoring being two examples. Likewise, any known preservative is suitable, with preferred preservatives being selected from the group consisting of sorbates (e.g., potassium sorbate), propionates (e.g., calcium propionate), and benzoates (e.g., sodium benzoate).
The inventive marshmallows are prepared by forming a mixture having a dough-like consistency and comprising sugar, water, the protein or protein-containing ingredient, and any additional ingredients as discussed above. During this forming step, preferably the dry ingredients are intimately blended and then mixed with a solution comprising the remaining ingredients at temperatures of less than about 120° F., and more preferably from about 70-80° F. Over-mixing should be avoided to prevent the dough from becoming too sticky. Preferred mixing times are less than about 15 minutes, and preferably from about 3-8 minutes. Also, during formation of the mixture, it is preferred that the mixing be carried out in such a manner so as to essentially avoid aeration of the mixture. Towards this end, none of the process should be carried out in any type of aeration device as is conventional in the prior art processes.
The resulting mixture is then dried in air having a temperature of from about 170-210° F. to yield the final chemically expanded product. As used herein, chemically expanded means the expansion takes place as a result of a chemical reaction within the product rather than by mechanical expansion such as by whipping or gas injection.
The foregoing temperature range is important because, if the temperature is too low, proper expansion of the product will not be obtained. On the other hand, if the temperature is too high, the product will be baked rather than simply dried and expanded. Preferably, the product is dr
