A Water Pasteurisation Indicator (WAPI) is a simple thermometer that indicates when water has reached pasteurisation temperature and is safe to drink. It consists of a small polycarbonate tube that contains a soybean wax that melts when water or milk is heated enough to be pasteurised (65˚C/149˚F). Since water pasteurises at temperatures well below its boiling point, WAPIs save time and fuel.
