Tostitos

Tostitos is a brand of Frito-Lay that produces different tortilla chips and a range of accompanying dips.
History.
By January 1978, Frito-Lay's product development group led by Jack Liczkowski had completed development of Tostitos. The chips were round, made of white corn and had an authentic "Mexican" flavor. Part of achieving this authenticity occurred after research discovered that Mexicans, after cooking corn with inorganic lime, did not rinse the corn completely and so the resulting stone-ground corn "masa" has a higher content of lime and higher pH. When the calcium hydroxide reacts with oil, it gives the chips this specific taste.
After successful test marketing in 1979, Tostitos Traditional Flavor and Tostitos Nacho Cheese Flavor went into national distribution in 1980 in the United States and reached sales of $140 million, making it one of the most successful new product introductions in Frito-Lay history. The chips are often eaten with a dip like salsa or nacho cheese, both of which the company also produces.
Varieties.
There are many varieties of Tostitos chips:
Some Frito-Lay brand seasoned products, including some flavors of Tostitos, contain pork enzymes in addition to herbs, cheese and other seasonings. Frito-Lay's web site states that they use enzymes from pigs (porcine enzymes) in some of their seasoned snack products to develop "unique flavors". The presence of pig-derived ingredients makes them unsuitable for vegetarians, vegans, as well as non-kosher and non-"halal".
Fiesta Bowl.
Starting in 1995, Tostitos became the title sponsor of the Fiesta Bowl, one of the four American college football games that would make up the Bowl Championship Series, the former unofficial national championship of the Division I Football Bowl Subdivision (formerly Division I-A). The game was played at Sun Devil Stadium in Tempe, Arizona through 2006 before moving to University of Phoenix Stadium in Glendale, Arizona in 2007.
Following the 2006 season, Tostitos was the title sponsor for the BCS National Championship Game, a new game matching the number one and two teams in the final BCS standings. The title sponsor for the championship game rotated depending upon which site is hosting the 1 vs. 2 matchup.
On June 9, 2014, Frito-Lay withdrew their sponsorship of the Fiesta Bowl citing the higher costs of sponsoring the event through the new College Football Playoff system.
