Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial application field) The present invention relates to a method for producing cooked rice for a microwave oven, and in particular, can easily produce cooked rice having sterilized cooked rice. The present invention relates to a method for producing cooked rice for a microwave oven.

(Related Art) Conventionally, retort cooked rice using white rice has been known as a retort food. This retort cooked rice is cooked with white rice, filled in a container, sealed, and then retort sterilized. Retort cooked rice that has been sterilized in this way is
It is said to have excellent storability, but differ in color, taste, etc. compared to cooked white rice.

In such a case, cooked white rice has been considered in which cooked white rice is filled in a container, sealed and sealed, and then heated in a microwave oven to be used in order to approximate cooked white rice. Further, there has been considered a cooked rice body for a microwave oven in which such a cooked rice for a microwave oven is filled and sealed.

It is said that cooked rice has a color and taste similar to cooked white rice, but since it is not subjected to retort sterilization, cooked rice filled in a container must be sterilized.

 Here, a general process of manufacturing cooked rice will be described.

First, brown rice is prepared, and various germs are attached to the brown rice. Subsequently, stone removal is performed from the brown rice, and then the bran is removed from the brown rice by a rice milling process to produce white rice. The white rice is further shaved while being cooled in the rice polishing step, and almost all the heat-resistant bacteria are removed. Next, in a refining process, water is added to the white rice with warm water.

In the rice polishing process, brown rice is subjected to a grinding action, and thus the manufactured white rice is in a high temperature state (about 50 ° C.). In addition, since the high temperature condition continues after the grinding rice polishing process and the refining process in which water is added by hot water, the white rice after the refining process is stored in the rice storage tank for about one day. It is stored and the temperature is lowered. Next, the cooled white rice is washed and subsequently soaked and cooked. The reason why the rice is washed after the temperature of the white rice is lowered is that when the rice is washed at a high temperature, cracks occur in the white rice.

(Problems to be Solved by the Invention) When producing cooked rice for a microwave oven as described above, the cooked rice needs to be sterilized at the stage of filling into a container. However, when cooked rice is produced by the above-described general production process, heat-resistant bacteria may propagate during storage in a rice storage tank.

In other words, most of the heat-resistant bacteria are removed in the rice polishing process, but when stored in a storage rice tank at about 50 ° C. for about one day, the temperature is suitable for the growth of the heat-resistant bacteria, so the propagation of the heat-resistant bacteria may occur. May happen.

On the other hand, it is necessary to prevent various germs from entering even when the rice is filled in the container.

The present invention has been made in view of such a point, and an object of the present invention is to provide a method of manufacturing a cooked rice body for a microwave oven that can easily and reliably manufacture a cooked rice body having sterilized cooked rice. I do.
