The present invention stems from the food industry, particularly from dough manufacturing processes having rheological features that are adequate for the production of food products made from a blend of flour and starch.
Dough is a complex and unstable food system consisting of a polymer network of the ingredients comprising it. Dough is traditionally made from flour and starch and dough's macro structural behavior depends on its manufacturing process, its elements and the existing ratio thereof. Existing studies on rheology and dough texture define the different components' influence, allows for quality control in the final product and guides the design and any adaptation of new technologies within the process.
The processes for obtaining dough include the addition of flour, starch, gluten, seeds, additives, and water, amongst others. The ratios at which the components are added will depend greatly on the desired final product. Starch is unique among carbohydrates existing in nature in the form of granules having amorphous and semi-crystalline regions. The physical organization of these granules regarding its functionality is widely renown for its critical importance, and therefore in how food products having starch-rich formulations behave. They are insoluble in cold water given their structure is highly organized, but they absorb water as its temperature rises. This process is called gelatinization, having a great impact in processing, quality and stability of starch-based products.
Prior art describes several processes for obtaining dough having appropriate rheological characteristics from flour and starch that contain as part of their makeup the adjustment or pre-gelatinization of starch. U.S. Pat. No. 5,747,092 describes a process for obtaining baked hors d'oeuvres made from wheat and potato flour and starch that includes the pre-gelatinization under specific stirring conditions and at temperatures between 80 and 100° C. for 30 minutes wherein the starch is incorporated in the flour until forming the dough, and then laminating and cutting said dough in small portions and the baking.
US20050208191 discloses a process for preparing dough and obtaining high protein snacks obtained by roasting and milling protein-rich cereals such as wheat, roasted peanut paste, sesame seeds, soy and corn starch; dissolving the ingredients comprising the dough in an additive-(for example, vitamins) enriched hot water composition until obtaining a homogenous dough; laminating and cutting the homogenous dough using a 3 to 4 mm-diameter circular matrix; and baking the pieces obtained in the above step at a temperature of 180 to 220° C. for 4 to 6 minutes.
Although prior art discloses several processes for obtaining dough from flour and starch, it is nevertheless necessary to develop processes that improve the rheological properties of dough in comparison with other dough for the production of other laminated baked products, and that require less production times, shortening the process and avoiding steps such as pre-gelatinization or gelatinization of starch comprising the dough.
The present invention allows obtaining dough from flour and starch having adequate rheological properties for the elaboration of baked products, in less time, using less equipment and reducing costs and increasing production.
The present invention refers to a process of producing dough having rheological characteristics that are adequate for manufacturing food products comprising: mixing dry ingredients in determined proportions and adding an adequate amount of water to the mix until obtaining a homogenous dough.
In order to obtain homogenous dough having rheological characteristics that is adequate for manufacturing food products according to the invention, dry ingredients (flour, starch and additives) must initially be mixed in determined proportions. Later, an adequate amount of water is added to the mix until obtaining homogenous dough. The homogenous dough may be laminated and cut into pieces that later can be baked until obtaining diverse products (
The necessary amount of dry ingredients must be initially weighed using appropriate weighing equipment, in order to mix them in a container in such a manner that the mix contains flour between 50 and 70% w/w, starch between 30 and 50% w/w and additives between 0.01 and 10% on a dry basis. One or more types of flour with one or more types of starches and additives may be mixed. Preferably, one type of flour, two starches and several additives are mixed.
Water is added to the obtained mix and with the indicated proportions above at a temperature between 35 and 90° C. at a mix:water ratio of 1:1, 2:1, 3:1 and 4:1. The addition of water may be carried out in the same container where the mixing is done in order to facilitate handling. The container can be a mixer or kneader, which must be operated under velocity and time conditions that allow obtaining homogenous dough. The homogenous dough obtained may be subject to further steps of lamination, cutting and baking.
In a preferred embodiment of the process, water is added to the mix of ingredients at a temperature between 40° C. and 50° C. at a mix:water ratio of 3:1 in a horizontal sigma arm mixer operated at a velocity of 20 and 30 rpm and for 4 to 8 minutes until obtaining homogenous dough.

The present invention will be presented in detail through the following examples, which are shown only for the purpose of illustration and not aimed at limiting its scope.
Flour and starch are initially weighed in a 65:35 ratio, i.e., 100 grams of wheat flour, 33 grams of yucca starch and 22 grams of potato starch is weighed, the latter characterized by a granulometry test shown in Table 3. Later, 6 grams of sugar and 1 gram of salt is weighed, which were added together with the flour and starch into a mixing container.
Dough for food products was prepared using flour and starch in a 62:38 ratio for which 89 grams of wheat flour, 11 grams of corn flour, 33 grams of yucca starch and 31 grams of potato starch was weighed, the latter characterized by a granulometry test shown in Table 3. Subsequently, 6 grams of sugar, 1.2 grams of salt, 13 grams of seeds and grain, 0.5 grams of flavoring and 0.023 grams of antioxidants were weighed and were added together with the flour and starch into a mixing container.
The dough of Example 1 and 2, to which water was added at a temperature of 50° C., was placed in the mixing container in a 67:33 mix/water ratio in order to obtain the dough homogenization. The resulting dough is mixed at a velocity of 20 rpm for 4 minutes in a horizontal sigma arm mixer until obtaining homogenous dough at a temperature of 40° C., characterized by a humidity of 34%.
The resulting homogenous dough is laminated using a set of rolls achieving a thickness of 0.9 mm. The resulting sheet is cut using an embossed cutting roll forming square pieces of 40×40 mm.
The cut and raw pieces are placed in a three-phase continuous oven wherein cooking is carried out continuously.
The baking process is divided in three phases, characterized by:
