Abstract
Methods of manufacturing shelf stable pods containing food or drink to be rapidly cooled, include inserting a mixing paddle into an aluminum can through an open end of a body of the can and sterilizing the can and mixing paddle at temperatures below a stress relief temperature of the can in a first aseptic chamber. The method also includes filling the can with a sterilized food or drink in the aseptic chamber, sealing a sterilized base of the can to the open end of the body of the can with a food-safe adhesive to create a hermetic seal, removing the can from the first aseptic chamber while maintaining the hermetic seal outside the first aseptic chamber, and mechanically seaming the base to the can.
