PACKED FROZEN SUSHI, ITS PRODUCING METHOD, AND ITS PREPARING METHOD

摘要

A vacuum-packed frozen sushi capable of being mass-produced and suitable for thawing in a microwave oven, its producing method, and a preparing method are provided. A vacuum-packed frozen sushi thawable in a microwave oven is produced by placing a packed sushi in a flexible plastic packing bag for microwave oven sealed hermetically under reduced internal pressure and by integrally freezing the sushi and packing bag. The packed sushi is characterized in that a food wrapping plastic film longer than the length in the long axis direction of the sushi is wrapped at least doubly around a part of the surface of the sushi, and at the opposite ends of the plastic film wrapped around the sushi in the long axis direction thereof, the plastic film is so provided as to be folded on the surface of the sushi. The steaming time after the heating through the microwave oven is shortened by forming a space between the sushi and the plastic film.
