ABSTRACT:
A food-grade oxygen scavenger for removing oxygen from foods and beverages in containers is prepared by immobilizing dried yeast containing at least 92% dry matter in a solid material such as wax or paraffin. The solid material allows for very slow penetration of water and permits the yeast to contact only water that penetrates therethrough. The immobilized yeast is coated on an inside surface of a container or on a surface of a closure such as a stopper that is on the inside of the container when closed. After adding a food or beverage and closing the container, the immobilized yeast removes oxygen from the container. The closed container and its contents can be pasteurized and the yeast retain sufficient viability to remove oxygen.
