摘要:
A microwavable vacuum-packed frozen sushi product comprising: a flexible microwave-safe plastic packing bag which is vacuumed to a pressure of 50 to 600 mmHg and, in the pressure-reduced state, hermetically sealed; an open-topped plastic box placed in said packing bag; and a sushi product placed in said box; said vacuum-packed frozen sushi product being such that a space is formed in said packing bag in the pressure-reduced state around said sushi product and the space has, in total, a volume 0.1 to 0.7 times that of said sushi product; an inner surface of said packing bag is in contact with an upper surface of said sushi product; and said packing bag, said box and said sushi product are frozen together in a unified form. Water vapor generated during thawing is allowed to flow through a space formed between the sushi material and the box and the packing bag to heat a rice section and a material or materials, thereby providing the sushi product with diminished unevenness in temperature distribution.

A packed frozen sushi product comprising a vacuumed, frozen and hermetically sealed flexible plastic bag, an open-topped plastic box placed in the bag, a laminated metal foil placed on the bottom of said box, and a frozen sushi product contained in the box with a surface or surfaces of its sushi material or materials on the laminated metal foil; the plastic bag, the box, the laminated metal foil and the frozen sushi product being frozen together in a unified form, the packed frozen sushi product thereby being adapted for microwave cooking. Water vapor emanating from the sushi product in thawing is allowed to flow through a space formed around the sushi material to heat a shaped rice section and the sushi material or materials, thereby diminishing unevenness in temperature distribution after thawing. By virtue thereof, a packed frozen sushi product suitable for mass production is provided.

摘要:
A process for thawing a frozen sushi product of a type packed by a plastic film by a microwave oven is provided. Each of a packed frozen sushi product of a type packed by a plastic film in which the entire sushi product is covered with the plastic film, and a frozen sushi product of a type packed by a plastic film in which an upper portion of a sushi material is covered with an aluminum foil, and the entire sushi product is covered with a plastic film with the aluminum foil located therebetween, can be thawed in a microwave oven by heating it by an electromagnetic wave heating to rise the temperature of an exposed side of a shaped form of boiled rice to 40.degree. C. or more, while rising the temperature of a contact area between the sushi material and the boiled rice portion to 15.degree. C. or less, and stopping the electromagnetic wave heating, whereby the sushi material is heated by a heat possessed by the boiled rice portion, until the temperature of the contact area between said sushi material and the boiled rice portion reaches a level higher than 15.degree. C. Thus, it is possible to use a microwave oven for thawing the frozen sushi product, and it is easy to thaw the frozen sushi product without heating the sushi material to a temperature exceeding 25.degree. C.
