Stacked chips
Stacked chips are a potato product similar to potato chips . They are made from potato dough.
The shape of many stacked chips can be described as a hyperbolic paraboloid . This shape increases the breaking strength. Some stacked chips, on the other hand, are simple parabolic cylinders .
development
The first and best-known brand for stackable chips are Pringles , which were first sold in 1968. Procter & Gamble was looking for a way to improve the chips after customers complained about broken chips and excessive air in the package. The chemist Fredric Baur designed the form, which was further developed and patented by Alexander Liepa. Gene Wolfe developed the machine for making the stacked chips.
Manufacturing
A dough-like intermediate product is rolled out from mashed potatoes or mashed potato powder, cut out and - fixed in a special holder - deep-fried , seasoned and packaged. This production method makes it possible to give the chips a uniform shape so that they can be packaged in a stack. The deep-frying process is designed so that the moisture content does not exceed three percent.
Stacked chips were u. a. Developed to counter storage-related fluctuations in the quality of the product, as the dehydrated mashed potato powder can be stored much better than the unprocessed potato. In addition, because of the lower moisture content of the puree, the specific energy requirement for the production of stacked chips is lower than for chip production. This also results in a lower fat content in stacked chips compared to potato chips, since the dwell time of the stacked chips in the deep fryer is shorter.
Stacked chips, like potato chips, can contain a high proportion of acrylamide under certain production conditions .
Stacking chips were introduced in Germany in 1978. The word mark “Stapelchips” has been protected from 1977 until the end of June 2026. It was registered by Intersnack Knabber-Pastry GmbH & Co. KG .
