ABSTRACT:
TECHNICAL FIELD
This invention is directed to a pre-baked product which is intended to be distributed in a refrigerated and/or frozen state and reheated by the consumer, such as in a toaster or toaster oven or on a grill, prior to consumption. The product is comprised of a filling, typically a cheese filling, which is fully enrobed in a dough crust to simulate a sandwich. The filing may contain flavors and/or particulate material, such as cubes of meat and/or vegetables.
DISCLOSURE OF THE INVENTION
This invention will be described with respect to a cheese filling. The filling is formulated such that when the product is baked or reheated the filling does not boil-out from the surrounding dough. During storage the filling retains moisture such that the baked dough does not become soggy and the filling has a creamy texture when the product is reheated by the consumer. The preferred filling is a dry-blended mixture which contains on a weight basis on a weight basis 94-99% process cheese ingredient,
The process used to formulate the dough for this invention include the typical dough making steps of: preparing a dough by mixing flour, (preferably having a protein-content of 11.5-13% by weight), water, yeast, salt, and saccharides, a freshness-promoting combination of a starch-degrading enzyme and emulsifier and shortening, the ingredients being present in proportions effective to produce an extrudable dough. The total content of the dough should be in the range of 14-16 Baker's percent.
One or more additional ingredients such as gum, vital wheat gluten, egg components and preservative may also be present. Typically the preservative (in an aqueous solution) is sprayed onto the product after baking. Suitable ingredient ranges are as follows:
Ingredient
Bakers Percent
Flour
100
Water
55-65
High Fructose Corn Syrup
5-8
(71% solids, 42% fructose)
Dry Instant Yeast
1-2
Salt
1-5
Wheat Gluten
1-4
Egg White Solids
0.5-3
Mono- & Diglycerides
0.5-2
Enzyme
0.2-2
Gum
0.1-0.8
Partially Hydrogenated Vegetable Oil
8-14
Preservative
0.01-0.5
The dough and the filling are combined to form a completely dough enrobed filling simulating a sandwich (i.e., top and bottom crust layer with sealed edges and a middle layer of cheese) or a filled tube (i.e., outer cylindrical crust with sealed ends and inner rod of filling). The dough enrobed product is proofed, baked, cooled and packaged, preferably vacuum packed in plastic film having an oxygen barrier layer such as ethylene vinyl alcohol. Before packaging the produced may be sprayed with a preservative, such as an aqueous solution of potassium sorbate. The product may be formulated to have at least a 90-day refrigerated shelf-life.
Suitable equipment to enrobe the filling is produced by Rheon Automatic Machinery Co., Ltd. Tsunoniya, Japan and is generally described in U.S. Pat. Nos. 4,883,687 and 5,223,277 which are hereby incorporated by reference. This equipment can produce a spherical or other shaped body consisting of a dough crust surrounding a filling. This body can then be molded into a desired shape. According to one embodiment of this invention a spherical body is shaped to a relatively flat, oval-shaped product by means of rollers. Alternatively the product of this invention could be produced by suitable dough sheeting and laminating apparatus and crimping devices such that the filling is completely enrobed. The maximum thickness of the unbaked, sandwich-type product should not exceed about 2.5 cm and preferably be on the order of 1.3 cm. This size will enable the baked product to be utilized in most household toaster.
The enrobing equipment may also be utilized to form an elongated, cylindrical product akin to the shape of a hot dog. A typical length for such a formed product is about 12-20 cm in length and about 2-4 cm in diameter. This shape, which is not compatible with toaster, could be reheated in a toaster oven or on a grill, such as the well-known roll grills commonly used to cook hot dogs in commercial establishments.
The products of this invention will desirably contain (weight basis prior to baking) 25 to 70% filling (including any particulates) and 30 to 75% dough. After baking the water activity of the crust and of the filling should be within 0.006 units. preferably within 0.04 units and most preferably within 0.002 units. Proper selection of dough and filling ingredients and baking conditions will enable this result.
The sandwich-type baked product will typically have crust layers having a thickness of about 0.2-0.5 cm and a filling layer having a thickness of about 0.5-1 cm. The cylindrical-shaped baked product will typically have an overall diameter of about 2-6 cm and a filling diameter of about 1-3 cm.
