Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for producing water-absorbed rice that can be placed in a container, subjected to water absorption treatment of heating and cooling, and placed in a container that can be distributed at room temperature, and can be placed in a chilled zone. The obtained water-absorbed rice in a container can provide rice having the scent and taste of freshly cooked rice by simple heating in 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 be completely sterile. Conventionally, water-absorbing rice packed in a single-serving container has been limited to frozen or refrigerated distribution.
However, even in refrigerated distribution, for some reason, the temperature may become normal temperature, and in some cases, water-absorbed rice distributed at normal temperature may be required.
Here, the production of aseptic water-absorbed rice was pressed.
[0005]
[Means for Solving the Problems]
In the present invention, immersed rice and / or rice subjected to a binding prevention treatment and / or sterilization treatment, or other raw rice, and a necessary amount of water or hot water or boiling water are put in a container, and If it is heated in an atmosphere of 85 ° C. to 130 ° C. for a short time and quickly put into cold water, the sterilization is completed in a short time, and the hot water in the container is first cooled by cooling. It was found that the temperature difference between the raw rice in the hot state and the raw rice absorbs the water in the container, thereby obtaining sterile water-absorbed rice.
[0006]
In the present invention, a container or a bag containing water soaked and / or anti-binding treated rice or other raw rice and water, hot water or hot water is welded to the lid or the mouth of the bag is welded. It is placed in an atmosphere of 85 ° C to 130 ° C, preferably 90 ° C to 125 ° C without a cover or a lid, and the product temperature in the container is 80 ° C to 110 ° C, preferably 85 ° C to 105 ° C, and optimal. After reaching 94 ° C. to 100 ° C., heating is performed for 1 second to 420 seconds, preferably 60 seconds to 180 seconds. After heating, those without a lid are covered or the lid is welded, and immediately It is used for producing water-absorbed rice in a container or a bag by putting the product in cold water and cooling the product temperature in the container to 20 ° C to 2 ° C, preferably 10 ° C to 2 ° C, more preferably 6 ° C to 2 ° C. is there.
[0007]
The rice in the present invention may be any of a mixture of milled rice, brown rice, milled rice for 7 minutes, germinated rice, glutinous rice, barley, millet, wheat, etc. The rice immersed for about 10 hours or in hot water at 20 ° C to 50 ° C for about 10 to 40 minutes is defined as the immersed rice of the present invention. In the present invention, if it does not bind when it becomes water-absorbed rice, only soaked rice can be used as a raw material. As the other raw rice, any rice used in the present invention such as sterilized rice with ozone and / or oxygen, sterilized rice with steam, roasted rice, and non-washed rice may be used. In the present invention, the soaked rice and / or the anti-binding rice or other raw rice is often referred to as raw rice.
[0008]
In the anti-binding treatment of the present invention, rice, which has been completely immersed in water, is put in a container such as a colander or a room-temperature edible container, and put into an autoclave. After heating for about 10 to 60 seconds, preferably for about 20 to 40 seconds, this prevents water-absorbed rice in the product container from binding to each other and forming a dango-like shape. The anti-binding rice may be mixed with the dipped rice to be used as a raw material.
[0009]
In the present invention, various containers can be used.
In the present invention, a container in which soaked rice and / or anti-binding rice or other raw rice and water or hot water or hot water are put into a single-serving tray, such as polypropylene and / or polypropylene, and an eval resin (EVOH resin). ) It is preferable that the lid is welded and sealed with the same material to the one obtained by laminating the membrane or the like into a single-edged shape, cutting a dish-shaped one, and cutting the same. Raw rice, with water or hot water or hot water put in, without a lid, but in this case, when heating in an atmosphere of 85 ° C ~ 130 ° C is finished, immediately put a lid made of the same material The edge is welded and sealed, or a bag capable of accommodating about 1 to 20 servings, preferably about 1 to 5 servings, for example, a bag made of a synthetic resin film or the like obtained by laminating polypropylene on nylon, Raw rice, and water or hot water or boiling water are put into this bag, and the mouth of the bag is welded and sealed or made of synthetic resin, and can accommodate from 1 to 20 servings, preferably from 1 to 5 servings. Box, for example, P.P. P filler or the like is molded into a box, and raw rice and hot water are kept in place without a lid. However, in this case, when heating in an atmosphere of 85 ° C. to 130 ° C. is completed, the same material is immediately used. Alternatively, a lid made of a different material is used to seal the joint between the bottom and the lid so that water, germs, fine dust and the like do not enter.
[0010]
In the present invention, the soaked rice and / or the anti-binding rice and the water or hot water or hot water are for one meal, and are 66 to 150 g (they are raw rice, so that the soaked rice is water-weighted). Water and / or hot water or hot water at 80 to 98 ° C. is about 45 to 450 g with respect to the anti-binding rice or other raw rice.
[0011]
In the present invention, the atmosphere at 85 ° C. to 130 ° C., preferably 90 ° C. to 125 ° C., is a very important point. When the atmosphere temperature falls below 85 ° C., rice and water are insufficiently heated to absorb water. It does not work well, and if the temperature exceeds 130 ° C., the container melts or becomes deformed and the rice becomes too boiled, which is not preferable. In order to maintain the atmosphere at 95 ° C. to 130 ° C., the heat capacity must be large.
In the present invention, an atmosphere of 85 ° C. to 130 ° C., preferably 90 ° C. to 125 ° C. as an optimum condition is formed by surrounding a raw rice with a high heat capacity retaining material and a container containing water or hot water or hot water. Good to be.
[0012]
In the present invention, the high heat capacity retaining material is selected from iron, ceramic, stone, rock and the like, and these high heat capacity retaining materials are directly heated by an electric heating element or pressurized steam or a heat conductive substance such as silicon oil. To heat the raw rice and a container containing water or hot water or hot water to maintain an atmosphere at 85 ° C to 130 ° C, preferably 90 ° C to 125 ° C.
[0013]
Also, specifically, a high heat capacity retaining material having a groove formed in the upper part corresponding to the width of the container, for example, a heat transfer material such as silicon oil at 85 ° C. to 130 ° C., preferably 90 ° C. to 125 ° C. Then, apply a Teflon (registered trademark) resin film on the lower surface of the groove (not necessary), slide the container containing the anti-binding rice and boiling water, and A high heat capacity retaining material heated to 85 ° C. to 130 ° C., preferably 90 ° C. to 125 ° C. using silicon or the like as a medium by electric heating or the like, for example, an iron plate heated on the top of a thick iron mass And an atmosphere of 85 ° C. to 130 ° C., preferably 90 ° C. to 125 ° C.
[0014]
In the present invention, the product temperature in the container (the product temperature of a mixture of soaked rice and / or anti-cohesion treated rice or other raw rice, and water or hot water or hot water) can be controlled immediately even when hot water is used first. As the cooling proceeds, it is preferable to put the container in an atmosphere of 85 ° C. to 130 ° C., preferably 90 ° C. to 125 ° C. as soon as possible. Under an atmosphere of 85 ° C to 130 ° C, preferably 90 ° C to 125 ° C, the temperature of the product in the container is raised to 80 ° C to 110 ° C, preferably 85 ° C to 105 ° C, optimally 94 ° C to 100 ° C. After the temperature reaches a predetermined temperature, heating is performed for 1 second to 420 seconds, preferably 60 seconds to 180 seconds, and the mixture is immediately poured into cold water.
[0015]
In the present invention, a container in which soaked rice and / or anti-binding rice, or other raw rice, and water or hot water or hot water at 80 ° C to 98 ° C, preferably 90 ° C to 95 ° C are placed, is covered with a lid. Without melting the lid or without welding the lid, in an atmosphere of 85 ° C to 130 ° C, preferably 90 ° C to 125 ° C. After being put into cold water, the hot water in the container is cooled immediately, and the temperature of the immersed rice and / or the anti-binding rice or other raw rice is 20 ° C to 2 ° C, preferably 10 ° C to By cooling to 2 ° C., more preferably 6 ° C. to 2 ° C., soaked and / or anti-cohesion treated rice or other raw rice absorbs water sufficiently and becomes excellent water-absorbed rice.
