Definitions

  • the invention relates to a method for preparing a flour tortilla
  • Flour tortillas are a unique baked product, made from cereal flour, usually maize or wheat.
  • Wheat flour tortillas are gluten structured, just like bread. Almost all tortillas are chemically leavened, baked quickly and cooled to ambient temperatures in less than 15 minutes.
  • Flour tortillas have soft, silky, smooth texture, are opaque and fluffy and have excellent pliability; are resistant to cracking and have small, evenly distributed bhsters. Blisters create desirable characteristics in the final product, showing up as lightly browned spots on the surface.
  • Flour tortillas are becoming increasing popular, for instance as a substitute for bread, rolls and buns.
  • Flour tortillas can be made by making a dough from flour, fat and salt and water (E.g. E.J. Pyler, Baking Science 7 Technology, Third Edition, Vol II, published by Sosland Publishing Company, Merriam, Kansas, USA). Most large commercial tortilla manufacturers use the hot-press method of mixing, forming and baking to produce flour tortillas, e.g. as described in Bello, A.B.; Serna-Saldivar, S.O.; Waniska, R.D. and Rooney, L.W. Methods to prepare and evaluate wheat tortillas, Cereal Foods World (1991)
  • a smooth dough comprising flour, water, fat, salt, and usually one or more ingredients selected from baking powder, yeast, preservatives, gums, reducing agents and emulsifiers is mixed to an extensible, elastic, non-sticky and relatively firm dough.
  • Dough temperature also affects consistency, with lower dough temperatures increasing water absorption. This leads to a softer final product.
  • the temperature may for instance be in the range of 27-38 °C.
  • the optimum temperature for flour-tortilla dough is usually 27° to 33.5°C.
  • the flour tortilla dough is scaled to a desired weight, usually from about 30 to about 150 gram, e.g. about 40 to about 50 gram or about 45 to about 48 gram, depending on the desired diameter for the tortilla, is rounded into a ball and is then allowed to rest (relax, proof), usually for about 5-15 minutes. Proofing the dough helps the pressing process. Insufficient relaxation can result in a translucent finished product with less layering.
  • the dough pieces After resting, the dough pieces are placed under a hydraulic press that is heated.
  • the pressing process forms a thin skin on the surface of the tortilla, limiting the escape of steam and carbon dioxide during baldng. This causes the tortilla initially to form small blisters or gas pockets which deflate upon cooling.
  • Baking is usually done in a conveyer oven that flips the tortilla over during its journey through the oven.
  • a specialized direct gas fired slatted belt may be used.
  • Baking time (oven dwell time) may for instance be approximately 30 seconds in a 190° to 235°C oven. In a specific embodiment, the oven temperature is 190-200 °C. The tortillas are then cooled and packaged.
  • the over-all quality of flour tortillas is determined by various properties.
  • a low fat content is generally desired from a consumer
  • Breaking it is desired that the tortilla shows good resistance against tearing. E.g. low-fat tortillas tend to be torn apart at a lower tearing force than regular tortillas.
  • a good tortilla should be easily rollable, e.g. around a known diameter dowel, rod or stick, without showing substantial cracking and/or breaking. This is especially a challenge upon aging of the tortillas.
  • Colour a product with a substantially uniform (off-)white colour, wherein blisters are present is appreciated by many consumers.
  • the blisters show up as lightly browned spots on the surface.
  • low-fat tortillas have a less off-white, more pale and less uniform colour.
  • Layering/lamination a layered structure of the tortilla is desired.
  • low-fat tortillas tend to be less layered compared to regular tortillas.
  • a tortilla should preferably have a not too dry mouthfeel
  • the size (diameter) of conventional reduced fat tortillas is significantly smaller than the size of regular -fat tortillas, of the same weight.
  • Low-fat tortillas of a specific weight may for instance have a diameter that is less than 90 % of the diameter of a regular-fat tortilla of the same weight and apart from the fat having the same composition
  • Uniformity size/shape Reduced fat tortillas tend to be less uniform in shape and size.
  • Stacking stickiness It is desired that -when stacked and packaged - tortillas show no or a low tendency to stick to one another. In particular, upon aging the tendency to stick may increase. In particular, tortillas known in the art, made with vegetable oil instead of sohd
  • tortillas known in the art, made with enzymes, such as bacterial or fungal amylases, tend to stick more to each other, regardless of shelf life.
  • Stack height As a consequence of smaller diameters, the height of a stack of, e.g., 10 tortillas is generally higher for reduced fat tortillas than for regular fat tortillas; i.e. low fat tortillas are thicker than regular tortillas. This is unwanted due to negative effects on rollability, foldability and eating characteristics.
  • Opacity is measured subjectively using a continuous scale. 100 % is completely opaque (white) and 0% is completely translucent (not white). Ideally, translucency is eliminated since opacity is a desired quahty attribute.
  • Fat in particular saturated fat (shortening) is conventionally used in a substantial amount to provide desirable properties, such as described above, especially for tortillas wherein at least a substantial part of the flour used for the dough is wheat flour.
  • Flour tortillas made with liquid fat (vegetable oil comprising a high content of unsaturated fat) address the health concern with respect to a high saturated fat content, but may also show rather high stickiness or zippering, like low-fat tortillas.
  • dough conditioners such as added emulsifiers, like monoglycerides and or diglycerides may needed (see e.g. Plyer page 1070, referring to 8 % shortening and 0.5 % dough conditioner, relative to the flour weight).
  • WO 2009/041821 it is described how a relatively simple measure surprisingly allows the preparation of a flour tortilla with good properties, such as rollabihty, stack height, etc as described above, at a relatively low fat content without needing dough conditioners. This is accomplished by applying a relatively low amount of a fatty substance to the tortilla dough prior to shaping. Although, this method provides good results, the dosing of fatty substance to the surface of the dough may require additional measures in order to be employed at a large industrial scale at low cost.
  • the invention relates to a method for preparing a flour tortilla, in particular a wheat flour tortilla, comprising
  • At least 65 %, preferably at least 70%, in particular 75- 100 % of the fatty acids are saturated fatty acids having 8-22 carbon atoms.

  • How well a flour tortilla performs on the rollability parameter can be assessing by wrapping the tortillas were wrapped around a dowel (1 cm diameter) by trained personal. This can also be (semi) quantitatively assessed by marking the extent to which cracking and breaking occurs using a scale from 1 (broken immediately, impossible to roll, i.e. no flour tortilla), via 3 (minor degree of cracking or breaking, allowing to consume it e.g. with a filling) to 5 (no cracks or breakage).
