April 20, 2021 | By Jori Skalitzky Cold milk has long been offered alongside a lunch or snack in elementary schools. Over the years, the vessel for that milk has remained the same – a traditional paper carton. Since those milk cartons require refrigerated storage and are far from beloved by students, both schools and the dairy industry have identified the need for another option to encourage milk consumption. To help address this need, Caroline Lunning, a UW–Madison undergraduate studying food science, partnered with three other students to develop an innovative design for a shelf-stable, quick-cool milk pouch. With support from an industry mentor, the team submitted their concept to the UW Dairy Innovation Hub Student Challenge.
