Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for producing germinated brown rice with enhanced calcium, and to a germinated brown rice with enhanced calcium produced by the method for germinated brown rice obtained by germinating brown rice.
[0002]
[Prior art]
Brown rice has a higher nutritional value than normal polished rice and is being reviewed as a healthy diet, but among them, germinated brown rice obtained by germinating brown rice is more digestive and absorbable than normal brown rice, nutrients, and texture. Because of their superiority, they are attracting attention as new functional foods.
[0003]
As described above, brown rice such as germinated brown rice contains many nutrients, but lacks minerals and vitamins mainly composed of calcium with respect to general nutrient requirements. On the other hand, there is disclosed an invention relating to germinated brown rice in which nutrients are enhanced by absorbing minerals and vitamins dissolved in water at the time of germination (for example, see Patent Document 1).
[0004]
Also, in order to germinate brown rice, it is usually necessary to immerse the rice in warm water of about 30 ° C. for about 20 to 30 hours. Therefore, there is a problem of deterioration of quality and generation of offensive odor due to growth of various germs.
[0005]
Regarding this problem, a method of exchanging water to be immersed in running water to remove bacteria (for example, see Patent Document 2) and a method of performing a sterilization treatment during immersion (for example, see Patent Document 3). Is disclosed.

[Problems to be solved by the invention]
Regarding the enhancement of minerals such as calcium, in the invention relating to germinated brown rice enriched with the above-mentioned nutrients, an example using a baked oyster shell is disclosed, but the material used for mineral enhancement is more effective. The challenge is to develop high quality materials. The material to be developed here is more preferable as long as it has an effect on other problems such as generation of various bacteria.
[0008]
In addition, regarding the deterioration of quality and the generation of offensive odor due to the growth of various bacteria, the method of disinfecting by exchanging water soaked with the above-mentioned running water and the method of performing sterilization during the soaking are for sterilization and sterilization. Since a process is required, there is a problem that a manufacturing process is complicated. It is still more preferable to solve such a problem only by immersing in water without requiring a special step.
[0009]
In response to these problems, the present invention has developed a immersion-enhancing material that contributes to the enhancement of calcium among minerals in germinated brown rice, and the generation of germs on germinated brown rice without passing through a special process. It is an object of the present invention to provide a method for producing sprouted brown rice with enhanced calcium and a sprouted brown rice with enhanced calcium produced by the method for solving the problem.
[0010]
[Means for Solving the Problems]
In order to solve these problems, the present invention is characterized in that germinated brown rice reinforced with calcium is produced by immersing brown rice in water containing baked scallop shell powder to cause germination.
[0011]
Since scallop shells are mainly composed of calcium, sprouted brown rice having a high calcium content can be produced by using the calcined powder. Also, if the scallop shell powder is thrown into water at room temperature, it emits far-infrared rays and produces an appropriate heating effect, so there is no need to overheat to maintain the water temperature during immersion, and the absorption of calcium from germinated brown rice Has the effect that calcium can be contained in a short time. When the immersion time is short, the growth of various bacteria can be suppressed.
[0012]
In addition, the present invention can also be characterized in that the fired powder of the scallop shell is obtained by pulverizing the scallop shell to about 200 μm and firing at about 1,050 ° C. in an oxygen-free state.
[0013]
The powder fired in this manner becomes a mixture containing calcium carbonate and calcium oxide as the main components, and can be used as a material that exhibits a high effect in each of the above points.
[0014]
In addition, the present invention can also be constituted as germinated brown rice reinforced with calcium produced by these production methods.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
The scallop shell baked powder used in the present invention may be obtained by pulverizing a scallop shell to about 200 μm and firing it at a high temperature (about 1,050 ° C.) in an oxygen-free state. The powder calcined in this manner becomes a multifunctional material having an antibacterial function and the like as a mixture mainly composed of calcium carbonate and calcium oxide. This calcined powder dissolves in water in an amount of about 0.1 wt% and has an alkaline property of a pH of about 12.5.
[0016]
The method of pulverizing the calcined powder is not particularly limited, and a general pulverizer may be used. The firing time is preferably about 3 hours, but is not particularly limited.
[0017]
In the production of germinated brown rice, the germinated rice is immersed in water. Although the water temperature varies depending on the rice variety, it is generally about 30 ° C. The immersion time needs to be about 20 to 30 hours, and since such an environment is suitable for the growth of various bacteria floating in the air, various kinds of bacteria can easily grow. By using water, replacing water every two hours, or performing sterilization treatment during immersion, deterioration of quality and generation of unpleasant odor due to growth of various bacteria are prevented.
[0018]
In the present invention, when the brown rice is immersed in water, the above-mentioned fired powder of the scallop shell is charged. The ratio of brown rice, water and scallop baked powder is preferably approximately 1: 1 to 0.3, but is not limited to this ratio.
[0019]
The temperature of the water to be immersed does not need to be heated to about 30 ° C. to maintain the temperature as in the above-described general method, and normal-temperature water may be used as it is. This is because when the above-mentioned fired powder of the scallop shell dissolves in water, it emits far-infrared rays and automatically heats the water to an appropriate temperature.
[0020]
About 5 hours of immersion time, a sufficient calcium adsorption effect can be obtained. This is because, similarly to the above, when the calcined scallop shell powder is dissolved in water, it emits far-infrared rays, which promotes the adsorption of calcium to brown rice. Thus, a sufficient effect can be obtained. If the immersion time is short, not only can the production time of the germinated brown rice be reduced, but also the time for the growth of various bacteria can be shortened. Can be.
[0021]
Furthermore, since the above-mentioned fired scallop shell powder has a strong antibacterial property due to alkalinity when dissolved in water, in addition to a short immersion time, the antibacterial property suppresses various bacteria and deteriorates the quality of germinated brown rice and unpleasant odor. It is effective for occurrence of.
[0022]
The germinated brown rice produced by such a production method contains 502 mg / 100 g of calcium according to the results of an analysis test by ICP emission spectrometry performed at the Japan Food Research Laboratories, which is generally sold. It contains about 50 times as much calcium as sprouted brown rice (calcium content about 10 mg / 100 g). As described above, it is possible to exert the effect of strengthening calcium more than conventional products while using a simple manufacturing method.
[0023]
【The invention's effect】
According to the present invention, sprouted brown rice in which calcium content is not sufficiently high in a normal production method can be produced more easily and in a shorter time than in a conventional production method.
[0024]
In addition, regarding the problem of bacterial growth that occurs during the process of producing germinated brown rice, a special process for sterilization will be required by shortening the time of immersion in water during the production process and making use of the antibacterial properties of the material. And the growth of various bacteria can be suppressed. As a result, it is possible to prevent the quality of the germinated brown rice from deteriorating and the generation of offensive odor.
