FEATURE: A WAY OF LIFE IN MEXICO

Stern Ingredients México offers customer service with its own pilot tortilla plant
Tortillas are the shooting star in the international fast-food sector and have long
competed for popularity with burgers, pizza,
etc. According to the industry service Market
Research Future, "The global tortilla market
has been witnessing a constant demand
over the last few years and is projected to
reach $48.51 billion at a CAGR of 5.1% by
2023."
The biggest markets are still North and
Latin America, but more consumers in Asia,
Africa and Europe are acquiring a taste for

"Tex-Mex" cuisine and boosting demand.
Stern Ingredients México (SIMEX), the
Mexican affiliate of the flour improvement
specialist Mühlenchemie, has prepared itself
for this continuing boom and invested in
a tortilla laboratory of its own. At the customer's request, product optimization and
innovations are carried out on the variable
pilot plant. How can a larger proportion of
soft wheat be integrated? What is the effect
of replacing lard with vegetable oil in the
recipe? What baking powder is the best rais-

break nor become soggy when prepared.

The dough is kneaded slowly, shaped into portions
of 30 to 90 grams, left to rest for at least 15 minutes,
then placed between the plates of a tortilla press (hot
press) heated to about 400 degrees F (200 degrees C).
A pressure of ca. 1,100 PSI (76 bar or 7.6 MPa) gives
the bread its characteristic shape. The diameter of the
tortilla is around 5.9 to 7.5 inches (15 to 19 cm), its
thickness 1.5 to 3 mm. Through direct contact heating, the starch in the dough already begins to paste in
the press.
The subsequent baking process takes less than a
minute. At industrial bakeries "triple pass" ovens are
widely used. The special construction of these multi-tiHUJDV¿UHGRYHQVSHUPLWVEDNLQJDWKLJKWHPSHUDWXUHV

FOCUS ON SHELF LIFE
The crucial topic for industrial producers is the shelf life
of the tortillas. Some retail chains demand a minimum
shelf life of three months for wrapped bread, and even
periods of up to 120 days are sometimes discussed.
The main reason for this is the logistic aspect. It may
take several weeks for the wrapped products to be delivered to the most distant parts of the country or exported abroad.
To ensure that the tortillas remain edible in the customer's home for as long as possible subsequently, they
must have a shelf life of several months.
Whereas microbiological problems can be solved
quite easily with preservatives like sorbic acid
(EMCEsorb), propionic acid (EMCEprop) and lactic

ing agent? Which product is most suitable
for delaying mold formation on the surface
of the baked foods?
The SIMEX applications technologists go
on analyzing the recipes and production parameters until the client's specifications have
been met in full.
This unique customer service is appreciated
far beyond the borders of Mexico. Tortilla producers around the globe send their flour samples to SIMEX, asking for recommendations
for optimizing their production processes.
