Description

  The present invention relates to a method for producing germinated oats containing abundant GABA and germinated oats.

Conventional oats contain abundant dietary fibers (eg, 8.1 g / 100 g) as nutrients in portions other than the outer shell, and further contain γ-aminobutyric acid (eg, 4 mg / 100 g).
The above dietary fiber is known to be effective in preventing diabetes and colon cancer, and the above-mentioned γ-aminobutyric acid (also referred to as GABA) suppresses hypertension, suppresses increase in triglycerides, menopause, stroke It is known to have preventive effects.
Therefore, in order to consume dietary fiber and GABA, oats are mixed with white rice and eaten.
As is widely known, the conventional method for producing oats containing dietary fiber and GABA is to prepare barley as a raw material, and to this, a process for removing barley husks, for example, a process of removing barley husks by a horizontal barley machine. A polishing process was added, and the heated and pressed barley was applied to the refined barley, and it was manufactured through a selection process so as to align the size of the pressed oats.
Therefore, when the oats are mixed with white rice, cooked and eaten, 95% to 99.9% or more of the outer skin is removed and the grains are evenly crushed to a predetermined thickness close to that of the rice grains. is there.
Furthermore, there is a feature that abundant dietary fiber and GABA contained in oats can be ingested.

Recently, there is a demand for more GABA.
However, Oshiba has only 4mg / 100g of GABA and has a limit.
By the way, it is known that malt (also called germinated barley) germinated barley contains abundant (eg, 15 mg / 100 g) GABA.
Therefore, the applicant company manufactures and provides oats in the same way as conventional manufacturing methods, using germinated barley that is rich in dietary fiber and rich in GABA as well as conventional oats. Tried.
However, in the conventional method for producing oats, if it is attempted to remove 95% or more of the germinated barley hulls using a horizontal sewage machine so as to improve the mouthfeel, the step of sufficiently removing the germinated barley hulls, for example, 95% or more. Many germinating barley is broken in the process of removing the barley.
Since germinated barley that is crushed smaller than a predetermined value of a size close to that of rice grains is selected and removed in the refining process, the germinated barley produced as a finished product has a low yield of about 10% or less.
Therefore, there exists a problem that the barley part containing nutrients, such as dietary fiber and GABA, cannot be processed with a sufficient yield.
This will increase the selling price of germinated oat products.
Furthermore, among the sprouted oats distributed in the market as commodities, many pieces that are larger than the predetermined value but crushed are mixed.
This may deteriorate the appearance of the sprouted oat product and lower the product value. In addition, there is a risk that the broken sprouted oats may be crushed more finely in the process of circulation, and the quality is further deteriorated.
Furthermore, when cooking and eating mixed with white rice, if there are many things that are crushed or broken and significantly smaller than the grain of rice, the crushed oats that are different in size from white rice in the mouth will feel uncomfortable as bobboso There was a problem that the feeling was bad and the rice was messed up, making it difficult to eat.

The object of the present application is to provide germinated oats rich in dietary fiber and containing a large amount of GABA and a method for producing the same.
Another purpose is to prevent germinated barley from being broken as much as possible in the processing step and to process the portion containing dietary fiber and GABA with a high yield even if the raw material is easily crushed germinated barley. And a method of manufacturing the same.
Furthermore, the present invention seeks to provide a sprouted oat that has less crushed barley and has a good appearance, and a method for producing the same.
Another object is to provide a sprouted oat that can be ingested with a good texture when mixed with white rice and cooked, and a method for producing the same.
Other objects and advantages will be readily apparent from the drawings and the following description associated therewith.

As shown in FIG. 1, the germinated oats 2 are manufactured through a process S1 for preparing a germinated barley 1 as a raw material, a pearling process S2, a hydrating process S3, a heating and pressing process S4, and a selective process S5. This will be described in detail below.

(Process S1 for preparing raw material germinated barley)
First, the germinated barley 1 which germinated the said barley is prepared. As the amount of germinated barley to be prepared, an arbitrary amount may be appropriately prepared in response to demand. For example, 3 tons are prepared.

(Wheat process S2)
The prepared germinated barley 1 is charged into the overhang 3. Next, the switching valve 5 of the elevator 4 is switched to set the discharge direction of the elevator 4 in the direction of arrow 6. Furthermore, the degree of the polished barley by the horizontal type barley machine 8 is set so that 85% or more of the outer skin of the germinated barley 1 is removed, and the operation of the barley equipment A is started.
Then, the germinated barley 1 introduced into the overhanging port 3 is carried in the direction of the arrow 30 by the elevator 4 and discharged to the tank 7.
The germinated barley 1 in the tank 7 is put into the horizontal type wheat mill 8.
The horizontal barley machine 8 removes 85% or more of the hulls of germinated barley 1 although there are variations.
Sprouted barley from which 85% or more of the outer skin is removed on the average is supplied to the elevator 4 through the path 9. (First step)
Next, the switching valve 5 in the elevator 4 is switched to set the discharge direction of the elevator 4 in the direction of the arrow 10. Furthermore, the degree of the polished barley by the vertical barley 14 is set so that 95% or more of the outer bark of the germinated barley 1 is removed, and the operation of the barley equipment A is started.
The germinated barley supplied to the elevator 4 in the first step is carried by the elevator 4 in the direction of arrow 10 and discharged to the tank 12.
The germinated barley in the tank 12 is put into the vertical slaughter 14. Since the outer barley of germinated barley has been removed by 85% or more in the previous stage, the germinated barley that has entered the above-mentioned vertical smelting machine 14 has slow damage, little damage, variation, but many have enough hulls (For example, 95% or more). (Second step)
In addition, although the operation | work which performs the setting of the said 2nd process after completion | finish of a 1st process was demonstrated, after setting the 1st process and the 2nd process previously, the driving | operation of the wheat polishing equipment A is started, and the 1st process and the 2nd process And may be automatically continuously operated.
In this way, first, 85% or more of the germinated barley hulls are removed using a horizontal rice flour machine as the first step, and then the germinated barley hulls remaining in the first step are used as the second step. Since the germination barley husk was removed 95% or more as sharpened using a machine, even if it is easy to break germinated barley, the germination barley is prevented from being broken as much as possible, dietary fiber and GABA, etc. Can be processed with good yield.

(Hydrolysis step S3)
Next, the germinated barley from which the hull has been removed is put into the water adding device 17, and the water is adjusted so that moisture is contained in the germinated barley from which the hull has been removed. The moisture of the germinated barley to be hydrated may be any moisture that prevents the germinated barley from being broken when the germinated barley is pressed. For example, germinated barley 1 having a moisture content of 4.0% becomes 14 to 20% moisture. The water may be adjusted as follows. Preferably, the water content is adjusted to 17%.
After hydration adjustment, germinate barley is put into tank 18 and left for a day. As a result, moisture uniformly penetrates into the germinated barley.

(Heating and pressing step S4)
Next, the germinated barley in the tank 18 is put into the pressing machine 20. The germinated barley put in the pressing machine 20 is heated in the process of passing through the preheating tower and the heating steam injection unit as is well known, and then pressed down to a predetermined thickness by the pressing roll 22.
The setting conditions for heating may be set so that the germinated barley is softened by heating and uniformly pressed. For example, boiler pressure: 5 kg / cm ² , heating temperature: 140 ° C., heating time: 15 minutes But you can.
The thickness of the pressed plate may be any thickness that is easy to eat and has a good texture when mixed with white rice, cooked, and eaten, and may be, for example, 1.8 mm to 2.0 mm.
By heating in this way, a sterilizing effect can be improved, and a product that is safe and safe for hygiene can be provided. Furthermore, there is a feature that the fragrance is improved by heating and the taste is increased.

(Selection process S5)
Next, the crushed barley 24 and the germinated oats are separated using a known shifter 23. As the size of the shifter 23, for example, a mesh of 12 mesh / inch may be used.
By using the shifter 23, grains of germinated oats having a size equal to or larger than a predetermined value can be arranged, and the appearance as a product is improved. Furthermore, there is also a feature that the texture is good when mixed with white rice and cooked.
Next, the crushed oats separated from the crushed barley 24 are passed through a color sorter 25 as necessary. As a result, when foreign matter is mixed in the germinated oats 1 of the raw material, the foreign matter 26 can be removed. This is because, for example, buckwheat (also referred to as crow oats) may be mixed as the foreign matter 26.

The germinated barley 2 is obtained through the step S1, the pearled step S2, the hydrating step S3, the heating and pressing step S4, and the selective step S5 of preparing the above raw material germinated barley 1.
As a result of analyzing the above-obtained germinated oats 2, the contents of dietary fiber and γ-aminobutyric acid (gaba) were as follows.
Dietary fiber: 8.2g / 100g (by enzyme-gravimetry)
γ-aminobutyric acid: 15mg / 100g (by automatic amino acid analysis)
The content of dietary fiber in germinated oat 2 was almost the same as the content of dietary fiber in conventional oats (8.1 g / 100 g).
The content of γ-aminobutyric acid in germinated oats 2 was about four times the content of γ-aminobutyric acid in conventional oats (4 g / 100 g).
Therefore, when the above-mentioned germinated oats 2 are mixed with white rice, cooked and ingested, the same dietary fiber can be ingested, and the GABA can be ingested about 4 times the conventional amount. This can meet the demands of health-conscious consumers.

Of the above-described examples, the embodiment of the pearled step S2 for removing the hull of germinated barley may be as follows.
Aspect 1:
As the first step, it may be circulated a plurality of times using the horizontal pearl mill 8 to remove the outer skin by 85% or more (or up to about 98%). That is, it may be as follows.
The prepared germinated barley 1 is put into the tension entrance 3.
Next, the switching valve 5 of the elevator 4 is switched to set the discharge direction of the elevator 4 in the direction of arrow 6. Furthermore, by passing the setting of the number of operations of the elevator 4 and the degree of wheat to the horizontal type wheat mill 8 any number of times, the hull of the germinated barley 1 is removed by 85% or more (or up to about 98%). Set and start the operation of the milled wheat equipment A.
Then, the germinated barley 1 introduced into the overhanging port 3 is carried in the direction of the arrow 30 by the elevator 4 and discharged to the tank 7. Next, the germinated barley 1 in the tank 7 is put into the horizontal type wheat mill 8.
The germinated barley 1 is refined by the horizontal wheat mill 8 according to the degree of the set wheat. The sprouted germinated barley is supplied to the elevator 4 through the route 9 and is subsequently carried in the direction of the arrow 30 by the elevator 4 and circulates in the order of the tank 7, the horizontal wheat mill 8, and the elevator 4. This circulation is repeated as many times as the number of operations of the elevator 4 set in advance. At the stage where the above set number of times has been completed, germinated barley has a lot of varieties, but more than 85% (or up to about 98%) of the outer skin is removed.
In this way, germinated barley 1 was circulated several times to remove more than 85% (or up to about 98%) of the hull, so the hard hull should be gradually removed over several times. Thus, compared to removing 85% or more of the hulls with a single blast operation, the crushed barley due to the pearl operation can be further prevented.
In the process of circulating processing, when one of the two tanks 12 and 13 is first polished, for example, through the tank 12, and then through the other tank 13, the wheat in the tank 12 The germinated barley that adheres to the wall and is not milled is prevented from being mixed with the germinated barley that is refined and circulates again. Therefore, there is an advantage that it is possible to prevent the occurrence of spots on the polished wheat.

Next, as a second step, the germinated barley from which the hulls have been removed by 85% or more (or up to about 98%) in the first step is circulated through the germinated barley several times using the vertical sewage machine 14 to More than 95% (or about 99.9%) may be removed.
In other words, by setting the number of operations of the elevator 4 and the degree of pearled wheat of the vertical barley 14 through the vertical barley 14 any number of times, the germination barley hull is 95% or more (or about 99.9%) Set to be removed. Furthermore, the setting of the discharge direction of the switching valve 5 in the elevator 4 is set so as to be alternately switched in the directions of the arrows 10 and 11, and the operation of the barley equipment A is started.
Then, the germinated barley supplied to the elevator 4 in the first step is carried by the elevator 4 in the direction of arrow 10 and discharged to the tank 12.
The germinated barley in the tank 12 is put into the vertical slaughter 14.
Then, the germinated barley is pulverized by the vertical pulverizer 14 in accordance with the set degree of pearl. The sprouted germinated barley is supplied to the elevator 4 through the path 15 and is subsequently carried in the direction of the arrow 30 by the elevator 4, and then circulates in the order of the tank 13, the vertical wheat mill 14, and the elevator 4. And it repeats by the operation | movement number of the elevator 4 set beforehand. At the stage where the above set number of times has been completed, germinated barley has many variations, but more than 95% (or 99.9%) of the outer skin is removed.
Thus, in the second step, germinated barley was circulated multiple times to remove 95% or more (or about 99.9%) of the hull.
This is because by removing the germinated barley hulls from which 85% or more of the hulls have been removed in the first step using the vertical sewage machine 14 a plurality of times, the hulls of 85% have been removed in the first step. The remaining germinated barley hulls that have been removed by more than% and are easily removed can be gradually removed so that they are sharpened multiple times.
Therefore, compared to removing 95% or more (or about 99.9%) of the hull by a single blasting operation, the crushed wheat caused by the blasting operation can be further prevented.
Therefore, even if it uses the germinated barley which is easy to crush, it can prevent the germination of the germinated barley as much as possible, and can process the part containing nutrients, such as dietary fiber and GABA, with a high yield.
When about 95% to 99.9% of the germinated barley husk is removed, the texture when the germinated barley 2 is mixed with white rice and cooked is better.

Preferably, the embodiment of the pearled step S2 for removing the outer bark of the germinated barley in the above examples may be as follows, for example.
Aspect 2:
In the case of removing the outer skin using the horizontal type wheat mill 8 as the first step,
For example, the conditions of the horizontal type wheat mill 8 are set using, for example, a 35 # grindstone, a rotational speed of 600 to 730 rpm (preferably 660 rpm), a flow rate of 400 Kg / hr, and a 1.2 mm vertical mesh. Remove 98% or more.
As a second step, the condition setting of the vertical pearl bar 14 is compared with, for example, the above-mentioned horizontal pearl bar 8, a fine grindstone (for example, a 60 # grindstone), a relatively slow rotational speed of 360 to 440 rpm (preferably 400 rpm), and comparison The flow rate may be as low as 300 kg / hr.
When passing through such a wheat polishing step S2, 1.67 tons of germinated barley from which 99.9% or more of the outer skin had been removed from 3 tons of germinated barley 1 was obtained. It can be processed efficiently with a yield of about 57%.
If it does as mentioned above, even if it uses the germinated barley which is easy to crush, it can prevent that the sprouted oats 2 are crushed as much as possible, and can process the part containing nutrients, such as a dietary fiber and a GABA, with a higher yield.
Further, when 99.9% or more of the germinated barley hulls are removed, the texture of the germinated barley 2 mixed with white rice, cooked and eaten is naturally improved.
