Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to germinated brown rice obtained by germinating brown rice. More particularly, the present invention relates to germinated brown rice in which minerals and vitamins are enriched as nutrients insufficient in brown rice, a method for producing the same, and germination thereof. It relates to processed food using brown rice.

[0002]

2. Description of the Related Art A milled rice obtained by milling brown rice removes various nutrients contained in the milled rice as rice bran during the milling process. Therefore, nutrients that must be fortified with milled rice to supplement the nutrients of milled rice. After being immersed in a liquid containing water and dried, a nutrient-enriched rice is produced by absorbing nutrients, and the enriched rice is mixed with an appropriate amount of polished rice at the time of cooking rice and used (for example, Japanese Unexamined Patent Publication No. Sho 63). -269956).
Another method is to cook rice by mixing a non-washed rice with a calcium source such as calcium lactate coated on a surface of unwashed rice from which rice bran attached to the surface has been removed after the milling (Japanese Unexamined Patent Publication No. 9-94071). Gazette), or
In a state of paddy, this is immersed in calcium ion water to strengthen calcium and then refined (Japanese Patent Laid-Open No. 56-99).
No. 759) is known.

[0003] However, in all of these methods, during the refining process, brown rice, which is a living organism, is first damaged to lose its self-preservation function, and various nutrients inherent in brown rice, which is also called complete food, are used. It removes as rice bran and slightly enhances calcium and vitamins among various nutrients lost.

[0004]

The inventors of the present invention have focused on the nutrients inherent in brown rice, and these brown rice have most of the nutrients necessary for maintaining health. In short, what is lacking is mainly minerals (especially calcium) and vitamins,
Others have a problem in texture and digestibility due to the fact that brown rice is sufficiently contained, making brown rice that is not fully utilized easy to eat, excellent in digestion and absorption, and insufficient. The present invention has been completed in order to provide a nutritional food that is as complete as possible using brown rice fortified with nutrients as a material.

[0005]

A first gist of the present invention is to enhance the nutrition obtained by absorbing minerals and / or vitamins dissolved in water into brown rice in the process of brown rice absorbing water and germinating. It is in germinated brown rice.

In the above description, the term “minerals and / or vitamins” is used in the present application to refer to “minerals and vitamins, minerals only, or vitamins only”.
Means the alternative case of the three cases. In addition, the period during which the minerals and / or vitamins dissolved in water are absorbed into brown rice may be the entire period from the time when brown rice is immersed in water to start absorbing water to the time when germinated, or into brown rice. May be limited to the initial period from 5 to 8 hours after the initial immersion when water absorption is most actively performed.
As the water in which the minerals are dissolved, an aqueous solution in which calcium, iron, zinc, potassium, and the like are dissolved in the form of inorganic salts is preferable because unpleasant smell does not adhere to brown rice. Examples of the vitamins include water-soluble vitamins such as vitamins B1, B2, and B6. Of course, mineral aqueous solutions obtained from raw materials derived from natural products such as oyster shells, corals, and animal bone meal, hot spring water that does not inhibit the germination of brown rice, seawater, and natural mineral water can be used.

[0007] A second aspect of the present invention is various processed foods obtained by using the enriched and germinated brown rice specified by the first aspect as it is or as a raw material.

In the above, processed foods made from germinated brown rice enriched in nutrition include cooked rice, retort processed foods such as porridge, rice cakes, rice crackers, confectionery foods such as arashi, rice cake confectionery, and processed brown rice powder. Food materials. In order to whiten the enriched germinated brown rice, the rice may be dried by an appropriate method such as drying by natural wind, sun drying, hot air drying and the like, and then milled by a rice mill.

A third aspect of the present invention is to immerse brown rice in water in which one or more minerals and / or vitamins are dissolved, absorb the water, and germinate the brown rice, so that the minerals and vitamins are contained in the brown rice. The present invention relates to a method for producing a fortified germinated brown rice, characterized in that the rice is enriched for nutrition.

[0010] A fourth aspect of the present invention is a method for producing a fortified germinated brown rice, characterized in that brown rice is immersed in water containing calcium ions to absorb water and germinate.

In the production method according to the third and fourth aspects, the germination of brown rice is completely completed in water in which minerals and vitamins are dissolved, and the component is dissolved only in the initial water absorption step. Performed in water, the germination process
This includes the case of performing in fresh water, in a high humidity atmosphere, or under intermittent watering conditions. Among minerals, calcium is particularly important for vertebrates, and in vivo, most of it is retained in the skeleton in the form of calcium phosphate, but calcium plays a crucial role in regulating physiological functions. I have. The invention according to the fourth aspect is characterized by the fact that the most deficient nutrients in brown rice are different from those in which a calcium compound is physically supported on rice grains as in a conventional calcium compound coating. In that it can be captured and held in
It does not cause adverse effects such as excessive intake of calcium and deterioration of food, and is ideal as a fortified food.

Examples of the compound that generates calcium ions in water include calcium chloride, calcium hypophosphite, calcium lactate, calcium dihydrogen phosphate, calcium gluconate, calcium glycerophosphate, and calcium pantothenate.

In the invention described in the first to fourth aspects, the temperature of water for germinating brown rice is appropriately selected usually in the range of 10 to 45 ° C., although it depends on the variety of rice. In the range of ３４34 ° C., the time required from immersion in water to germination is short. The time required for the brown rice to reach the germination state is about 15 to 72 hours in the above range of 10 to 45 ° C.

In order to germinate brown rice, the rice may be soaked in water until it germinates. Alternatively, when the rice is soaked in water and the brown rice grains have sufficiently absorbed water, the brown rice is taken out of the water bath and subjected to high humidity (relative humidity of 1%).
Germination may be carried out in an atmosphere (preferably maintained at 00%).

[0015] In order to prevent fermentation of water and to prevent germination of germinated brown rice, air containing ozone generated by an ozone generator is directly aerated into water containing brown rice, or ozone is used. Dissolved water may be circulated and supplied from the storage tank to allow ozone to coexist in the water,
When minerals and vitamins are dissolved in water, it is limited to the case where the vitamins and minerals are not oxidized, deteriorated or decomposed by ozone.

Ozone depends on the quality of water used and the degree of washing of brown rice. In general, water in which ozone is dissolved at a concentration of 0.01 ppm retains bacteria, Escherichia coli, viruses, etc. for less than one minute. In time, it exerts a bactericidal effect. Therefore,
The ozone concentration of the water in which the brown rice is immersed may be intermittently set to be equal to or higher than a predetermined concentration for a predetermined time as long as no fermentation odor or off-flavor is generated.

Further, after water containing minerals and the like is sufficiently absorbed by brown rice, the water is pulled out of the water, and air containing ozone (at an ozone concentration of 0.03 to 0.1 ppm) is introduced into the atmosphere surrounding the brown rice. Is sufficient), may be constantly circulated or may be intermittently fed, or water containing ozone at a predetermined concentration or more may be sprayed in a shower form for a predetermined period of time to sterilize or stop fermentation and replenish moisture. May be performed. In general, it is somewhat difficult to control the humidity to take out from the water bath and germinate in the air, but the operation for preventing fermentation becomes easy. As an eclectic type of germination in water and germination in the air, after immersing minerals etc. in water that dissolves them and allowing them to absorb enough water, periodically spray water that dissolves ozone on brown rice extracted from the water. It may be a method.

The degree of germination is 0.5 to 1 mm
Ideally, a state in which the front and rear bulges or protrusions are visible. The sprouted brown rice in the present application is also assumed to include brown rice in a sprout state (a state in which the swelling of the embryo part is finally visible) before the sprout becomes a projection state. If such sprouted brown rice is cooked or steamed with the addition of an appropriate amount of water, almost no granular matter remains, the texture is smooth, and the nutritional value is also the most excellent in rice or porridge, or Mochi and other processed foods. As the germination state progresses (the buds protrude from the germ part to a protrusion of about 3 mm), sugars such as starch of brown rice are rapidly lost, and the taste of processed foods such as rice cakes and porridge is lost. descend. Conversely, when germinated brown rice is eaten as it is, mastication becomes easy and the texture is improved. Therefore, as soon as germination is completed, the germinated brown rice is cooled to at least 6 ° C. or less. Desirably, it is good to cool and store it in a frozen state.

In the germinated brown rice thus obtained,
In the process from water absorption to germination, minerals and vitamins such as calcium dissolved in water are absorbed into brown rice, so for example, among the nutrient components of brown rice that are said to be close to complete food, calcium is particularly deficient Calcium-enriched brown rice rich in natural ingredients can be produced. In the germination process, the germinated brown rice changes its component proteins into more useful amino acids, monosaccharides are added to the sugar, and sweetness is added. Depending on the concentration of minerals dissolved in water, the amount of minerals etc. absorbed by brown rice grains also changes, but this should be done at a concentration within the limit that does not impair the growth environment of brown rice as a living organism It is.

In general, brown rice, when germinated, has an effect that the water in which ozone is dissolved works effectively by activating the metabolic action, thereby promoting germination and uniforming the germination state. In order to effectively exert the germination promoting effect, it is effective to stir water and to supply brown rice grains with abundantly supplied water having a low concentration of ozone. For example, in order to make the germination state uniform, it is effective to supply water having an ozone concentration of less than 0.01 ppm during the germination period.

The obtained enriched and germinated brown rice is dried and polished, and can be used and processed in the same manner as in the conventional case, depending on the intended use. For example, when rice cake is used as the raw brown rice, after the germination is completed, the rice cake may be used as it is by a conventional method, or for a rice cake raw confectionery, the germinated brown rice may be dried and then refined to make rice cake. Unpolished, enriched, sprouted brown rice is rich in minerals and rich in dietary fiber and vitamin E. In addition, even when refined, the content of dietary fiber and vitamin E is inferior to that of unpolished, but other vitamins and various amino acids are contained more abundantly than ordinary polished rice. It is a nutritious processed food.

EXAMPLE After washing 450 g of Koshihikari brown rice from Nagano with water, 675 g of water was added thereto, followed by cooking calcium (food calcium preparation manufactured by Healthcare Tech Co., Ltd .:
The baked oyster shell was powdered, extracted with water, and 50 g of water-soluble calcium lactate (obtained by evaporating and drying the aqueous phase) was dissolved, and the water temperature was maintained at 31 ° C. for 20 hours. . As a control, 675 g of water was added to 450 g of the same kind of brown rice washed with water, and the water temperature was kept at 31 ° C. for 20 hours. After 20 hours, germination was almost completely observed in the brown rice grains, which were washed with water, drained, sealed in a polypropylene bag, and immediately flash-frozen. This frozen product was sent to the Japan Food Research Laboratories and analyzed for components. Table 1 shows the results.

[0023]

[Table 1] For reference, the dry matter calcium value calculated by assuming that water is 0 is 203.3 mg / 10 in Ca-enhanced germinated brown rice.
0 g and 16.7 mg / 100 g for germinated brown rice.

[0024]

[Effect] As is clear from Table 1, according to the method of the present invention,
By germinating in water containing minerals and the like, various cell functions, including cell membranes, are activated at the germination stage and actively absorb water and nutrients, so that a large amount of minerals and vitamins Can be absorbed, and fortification can be remarkably achieved as compared with the conventional method. In particular, calcium is an essential mineral for mammals, but brown rice has a significant lack of calcium, which is the only nutritional component of brown rice that contains most other necessary ingredients. However, it is of great significance that this can be improved in the form of natural foods.
