Description: [0001] The present invention relates to processed rice foods that can easily produce cooked rice of a quality suitable for gourmet tastes. [Prior Art] There is a known method of storing pre-cooked rice in a waterproof pack, placing the pack in boiling water to heat it, and heating and eating the rice stored in the pack. The product is actually commercially available. However, since this method involves reheating rice that has already been cooked, it is impossible to obtain the same taste as when the rice is cooked. [0003] Also, a bag with small holes is filled with polished rice or pregelatinized rice, and this is heated in boiling water for a predetermined period of time to cook the rice.
It is also known to take out the perforated bag in which the rice is stored and eat it (Japanese Patent Application Laid-open No. 49-75748, Japanese Patent Publication No. 6
4-7740), some such products are also on the market. However, when pregelatinized rice is used,
It is still lacking in taste, and is only partially used as emergency food for the Self-Defense Forces, making it intolerable for ordinary households to eat. Also, in the case of polished rice, it is not suitable for regular meals due to its flavor, texture, etc. Furthermore, in the case of polished rice, it is necessary to soak the rice in water before heating it, which is greatly inferior in terms of convenience. [Problems to be Solved by the Invention] The present invention provides a simple rice-cooking type rice processing method that can easily produce rice with gourmet quality without requiring a rice cooker. It provides food. [Means for Solving the Problems] In order to make rice cooking easier, it is necessary to use gelatinized rice instead of polished rice. [0007] In addition to being easy to cook, gelatinized rice is inherently superior in flavor and texture after cooking. As a result of intensive research into forms that would allow easy cooking while taking advantage of the excellent flavor and texture of pregelatinized rice, it was discovered that the pore diameter and porosity of the porous container are important. In the conventional simple rice cooking method, no consideration was given to these points, and in particular, the aperture ratio was too small. The easily cooked rice processed food of the present invention is a rice processed food in which a predetermined amount of pregelatinized rice is filled in a container having a large number of small holes and cooked, and the small hole diameter of the container is 0.05 to 3.0 m.
m, and the container has a porosity of 0.2 to 3.0%. [Embodiment] FIG. 1 shows a bag-shaped container 11 used in the present invention.
FIG. 2 is a plan view showing an embodiment of the present invention, showing only the planar shape of the container 11 before it is filled with gelatinized rice. FIG. 2 is a sectional view showing an embodiment of the processed rice food 31 of the present invention. however,
The small hole 13 bored in the wall of the container 11 is not shown (the cross section is taken at a part where the small hole 13 does not appear).
. [0010] The container 11 is made of a heat-resistant flexible plastic film that can withstand heating during rice cooking, and its periphery is heat-sealed to form a bag-like body. 1
5 indicates a seal portion. Examples of such plastic films include synthetic resin films and laminate films such as polypropylene films and polyethylene terephthalate/polyethylene laminate films. A large number of small diameters 13 are formed on the wall of the bag-like container 11.
are perforated almost uniformly throughout the container. The diameter of the small hole 13 is 0.05 to 3.0 mm, preferably 1.0 to 2.0 mm. Note that the material of the bag-like container 11 itself is water-impermeable. If the pore diameter is less than 0.05 mm, it will take a long time to cook, and if the heating time is kept constant, the rice will have a slightly hard texture.On the other hand, if you continue heating to improve this, the rice will be cooked unevenly. The taste is poor in both cases. In addition, the hole diameter is 3.0 mm
If it exceeds this amount, rice grains may spill out when filling with pregelatinized rice, and the rice will feel watery after cooking, resulting in poor taste. [0012] The porosity of the bag-like container 11 is 0.2 to 3.0.
%, preferably 0.8 to 2.5%. If the porosity is less than 0.2%, it will take a long time to cook the rice, and if the heating time is kept constant, the rice will have a slightly hard texture.On the other hand, if the heating is continued to improve this, the flavor will be poor. . On the other hand, if the porosity exceeds 3.0%, the rice will be slightly watery in texture. Note that the porosity refers to the surface area of the container 11 (for example, A× in FIG.
This is the ratio of the total area of the small holes 13 (both the front and back surfaces of the bag-like body) to B×2 (not including the seal portion 15). In FIG. 1, small holes 13 with a diameter of 2 mm are bored at a pitch of 12 mm in a bag-like container 11 with an inner dimension of 140 mm x 90 mm, and the pore size is approximately 2.
.. The figure shows a state of 4%. The bag-shaped container 11 is filled with gelatinized rice 21. The degree of gelatinization of gelatinized rice is preferably in the range of 60 to 100%, more preferably 65 to 80%. When the degree of gelatinization is less than 60%, it takes time to cook rice, which is a problem in terms of convenience. Note that if the degree of gelatinization is too high, the structure of the rice grains will become hard and the absorption of water will be delayed, resulting in a tendency for the rice to be somewhat tough. The degree of gelatinization is measured using the turbidity method (Home Economics Magazine, Vol. 24,
No. 1, p. 45-48 (1973)). [0014] Pregelatinized rice can be produced by a method in which white rice is cooked and then dried with hot air, or a method in which white rice is pregelatinized and dried using steam, but the present invention does not particularly limit this production method. In addition to the gelatinized rice 21, the bag-like container 11 also contains vegetables,
It can be filled with ingredients such as beans, meat, seafood, and cheese, as well as seasonings and coloring, and can also be used to cook red rice, rice, pilaf, etc. When cooking rice, processed rice food 31 is prepared by filling a perforated bag-like container 11 with pregelatinized rice 21 as shown in FIG.
Rice can be obtained by heating in boiling water or steam for 5 to 15 minutes, and then steaming for 2 to 10 minutes. Effects of the Invention According to the present invention, a water-impermeable material such as a plastic film is used as a container material, a large number of small holes with a hole diameter of 0.05 to 3.0 mm are bored in the container, and By setting the porosity of the container in the range of 0.2 to 3.0% with small holes, while taking advantage of the excellent texture and flavor of the pregelatinized rice filled in the container, it is possible to improve the taste with a short and simple processing. You can get good rice. Therefore, in the past, α could only be used as an emergency ration of bag-cooked processed rice food.
The modified rice can be eaten more deliciously and easily, and is suitably used as a preserved food, an emergency food, a portable food, and as a food that can withstand home meals. Furthermore, since the processed rice food of the present invention is stored in a container such as a bag, it can be used as a portable food when hiking, mountain climbing, traveling abroad, etc. For single people, students living in boarding houses, etc.
It has become possible to eat small amounts of rice easily and deliciously, and it also has the effect of developing new demand for rice. [Example] A bag-like container similar to the one shown in FIG. 1 was prepared and subjected to evaluation. Here, a dry laminate film of polyethylene terephthalate and polyethylene was used as the material for the bag-like container. In addition, the inner dimensions of the bag-like container (A
xB) was set to 140 x 90 mm. The pore diameter and porosity of the bag-like containers were evaluated by preparing various bags as shown in Examples 1 to 5 below. Inside the bag-shaped container, there are 116 gelatinized rice made from Akita Komachi.
g filled. Here, gelatinization is produced by soaking Akita Komachi polished rice in water, cooking it, cooling it to about 70-80°C, and drying it with hot air at 80-120°C using a dryer.
I got it with a degree of compatibility. The obtained pregelatinized rice was stored in a bag-like container, and sample No. 1 of each Example was stored. 1 to 50 processed rice foods were obtained. These processed rice foods were heated by immersing them in boiling water for 15 minutes, then steamed for 10 minutes to cook rice, and the taste was sensory-evaluated by a specialized panel according to the following criteria. Evaluation Criteria ○: Good △: Not good ×: Bad 0022 Example 1 A hole with a hole diameter of 0.03 mm was placed in a bag-like container with the opening ratio shown in Table 1 below. Pregelatinized rice having the degree of gelatinization shown in Table 1 was filled and cooked, and the taste was sensory evaluated. Example 2 Pregelatinized rice having the degree of gelatinization shown in Table 2 was filled into a bag-like container in which a hole with a hole diameter of 0.075 mm was opened with the porosity shown in Table 2 below, and the rice was cooked. The taste was sensory evaluated. Example 3 Pregelatinized rice having the degree of gelatinization shown in Table 3 was filled into a bag-like container in which holes with a hole diameter of 2.0 mm were opened with the porosity shown in Table 3 below, and rice was cooked.
