Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for producing a container or a bag containing water-absorbed rice that can be distributed at room temperature by performing water absorption treatment of heating and cooling in a container or bag, and the container obtained by the present invention. Or, the water-absorbed rice in a bag can provide rice with the scent and taste of freshly cooked rice by simple heating with a microwave oven at home or a restaurant.
[0002]
[Prior art]
Generally speaking, water-absorbed rice is not rice cooked completely, but rice is heated and water is absorbed, but the degree of α-formation is suppressed to 85% or less (α-degree 85% to 30% is preferable). The required amount of water is absorbed and heated before eating to make freshly cooked rice.
Then, the inventor repeated heating, cooling, and water absorption, and made water-absorbed rice obtained by absorbing 72 to 130 parts by weight of water with respect to 100 parts by weight of rice (Japanese Patent No. 2821562) without completely turning into α. We have also developed ultra-high water absorption rice with higher water absorption.
[0003]
However, conventionally, a large amount of rice has been processed to produce water-absorbed rice at a stroke. Therefore, in order to make water-absorbed rice for one meal, it has been necessary to repack in a single-food container.
[0004]
[Problems to be solved by the invention]
When refilling water-absorbed rice in a single-serving container, it is extremely difficult to make it completely sterile, and conventional single-serving container-filled water-absorbing rice has been limited to frozen circulation or refrigerated distribution.
However, even in refrigerated distribution, for some reasons, the temperature may become normal, and water-absorbed rice distributed at normal temperature has been required.
Here, it was necessary to produce aseptic water-absorbed rice.
[0005]
[Means for Solving the Problems]
In the present invention, after the raw material rice and the like and water and the like are sealed and heated in a hot water and / or steam and / or a pressurized steam, and the product temperature in the container reaches 70 to 140 ° C. If it is heated for 1 second to 30 minutes and immediately put into cold water after heating, sterilization is completed in a short time, and the hot water in the container or bag is first cooled by cooling. It was found that the temperature difference from the rice in the hot state caused the rice to absorb the water in the container or bag, thereby obtaining almost sterile water-absorbed rice.
In the present invention, soaked rice and / or anti-binding rice and / or other raw rice may be collectively referred to as “raw rice or the like”.
In the present invention, water, hot water, hot water and / or dash juice may be collectively referred to as “water or the like”.
