We’re often asked what our favourite crisp facts are. Let’s face it: few things are as consistently enthralling as crisps, which makes singling out our favourite facts quite difficult. Testament to this is the sheer number of news titles specifically devoted to potatoes, the principal ingredient of crisps. There’s PotatoBusiness.com, Potato, Potato Review, Chinese Potato Journal, Potato Processing International, World Potato Markets, Potato Business Digital, The New Potato, American Journal of Potato Research, Potato Country and Potato Pro.
According to Google Scholar, there are more than 250,000 studies referencing potato crisps or potato chips. Some of these are page-turning bedtime reading. For instance:
- “Addition of antioxidant of bamboo leaves effectively reduces acrylamide formation in potato crisps and French fries.”
- “Fast detection of rancidity in potato crisps using e-noses based on mass spectrometry or gas sensors.”
- “Objective and subjective measurement of the crispness of crisps from four potato varieties.”
It’s great to see such a rich and vibrant body of academic research. We hope that these studies – and our site in general – inspire a new generation of crisp enthusiasts.
Turning to our favourite facts:

Professor William E. Lee, a chemical and biomedical engineering professor at the University of South Florida in Tampa, has a patent on crisp technology. For six years, he studied the sensory attributes of crisps and has become a leader in the field of crunchiness. When snack manufacturers need advice on crunch, they call Professor Lee.
During World War II, crisps were declared a non-essential food in the US and production stopped. After protests, crisps were re-classified ‘essential’ and production resumed.
