Tostitos is a brand of tortilla chips and dips produced by Frito-Lay and introduced in 1979, with national distribution in the United States reached in 1981. They are made from all-white corn. Traditionally, Tostitos chips contain no extra flavoring or preservatives, and thus are advertised to be suited for dipping. They are lightly salted, however. Chips are about 1 ? of an inch in diameter, and are often eaten with salsa or nacho cheese dip, which the company also produces. Some Frito-Lay brand seasoned products, including some flavors of Tostitos, contain pork enzymes in addition to herbs, cheese and other seasonings.

The presence of pig-derived ingredients makes them unsuitable for Vegetarians, Vegans, as well as non-kosher , and haraam . read more
