Scientists at Michigan State University are studying a gene in potatoes that causes cold-induced sweetening (CIS), a process that increases levels of the carcinogen acrylamide when the potatoes are fried. Their research could lead to the creation of potato varieties that resist CIS, thereby reducing acrylamide levels without impacting taste or production costs. This development could have significant implications for the snack industry, especially in Michigan where it generates $240 million annually.
