Flour Tortillas

What are flour tortillas?

Flour tortillas are flat and circular breads used as the base for traditional Mexican foods such as tacos, burritos, quesadillas and enchiladas. They are usually eaten warm with a topping that may include cheese, meat, and a variety of spicy sauces.

Flour tortillas are different from corn or masa tortillas. They are made from wheat flour dough that is either:

  • Leavened by steam generated during baking
  • Raised lightly with a small amount of baking powder/yeast

Wheat flour tortillas originated in Northern Mexico (Sonora area) and areas close to Texas during the Spanish domination. As wheat was gradually introduced into Mexican cuisine, the flour tortilla was developed to satisfy the preferences of Spaniards, mestizos and Americans.1

This situation caused a partial “substitution” of traditional corn-based tortillas. The use of flour tortillas for Tex-Mex food started in the 1950s with the Mexicans migration to the US which brought methods and formulations for producing flour tortillas.1

According to the Tortilla Industry Association (TIA), tortillas are the fastest growing segment of the U.S. baking industry with a total sales greater than $12 billion. Tortillas represent about 30% of the sales, making them the second most popular bread type in America after white pan bread, surpassing products such as whole wheat bread, bagels, and rolls.1

How are flour tortillas made?

All flour tortillas contain at least four basic ingredients: wheat flour, water, fat, and salt. Flour tortillas are typically 3/64″ – 5/64″ (1.0–2.0 mm) thick and have diameters of 6.0″ –12.0″ (15.0–35.0 cm).

* All purpose flour can be used.
** Baking powder can be used instead of yeast (1.5–2.0% based on flour weight).
*** Different types and levels can be used, depending on dough handling properties desired, machinability (rollability) and target flavor and shelf-life.

Production process

Tortillas can be industrially produced by dough pressing (hot-press) and extrusion (die-cut). Each operation requires different flour specifications, dough handling properties, and baking conditions, which result in various tortilla characteristics.

The dough pressing operation, a more automated procedure, involves pressing the round and proofed dough pieces in a heated, hydraulic stamping equipment.

In general, hot-press flour tortillas compared with die-cut are smoother in surface texture, more elastic, slightly chewy, and resistant to tearing and cracking. Hot-press tortillas are the most popular and account for more than 90% of the retail market.2

Tortilla dough is extruded in a continuous band, followed by sheeting and cross rolling to the correct thickness  1⁄2” – 2 1/2″ (0.5 – 2.5 mm) and cutting with a circular die into individual round pieces whose diameter is identical to that of the die.

Depending on the elasticity or extensibility of the dough, the cutter may be designed to be slightly oblong to compensate for shrinkage after cutting.The die-cut method greatly reduces the cost of producing tortillas.2

Processing specifications1,2,3

  • Mixing. Mix to obtain proper extensibility. Mixing time of 5–12 min. The optimum dough temperature should be 89–93°F (32–34°C).
  • Proofing. Proof for 5–20 minutes at  82–86oF (28–30°C) and a moist environment of 85% RH.
  • Baking. Given product dimensions, tortilla disks are baked at 350–500°F (177–260°C) for 20–50 seconds, usually in direct gas-fired ovens. The higher the oven temperature, the shorter the baking time.
  • Cooling. Product is cooled to less than 89oF (32°C) for 2–5 minutes on cooling conveyors before placing into plastic bags for distribution.


For mold inhibitors, Potassium sorbate (10% solution as spray), calcium propionate, vinegar (100 grain) and sorbic acid can be used. Levels cannot exceed legal limits established by the FDA. Mold inhibitors never replace good manufacturing practices. The best way to extend shelf-life is by following strict pre-requisite programs and having a food safety management system in place.

ADA (azodicarbonamide), potassium bromate, ascorbic acid, can be used to increase dough strength. Oxidizing agents reduce rollability or extensibility of dough.
