DISCLOSURE OF THE INVENTION Conventionally, wheat, barley, rye, oats, and the like are powdered for use as young barley leaves for use in cooking or beverages, and there is no technique for powdering these young barley leaves. , Chlorophyll, vitamins, minerals,
There is a problem that young barley leaves rich in nutrients such as dietary fiber cannot be used.

The present invention is intended to provide a method for producing a young barley leaf powder which is a powder of young barley leaf such as wheat, barley, rye, oats, etc., which has not been used in the past, and which can be used for cooking or drinking. It is what

[0005]

The present invention provides 30-40c.
m, a mowing step for mowing young wheat leaves that have grown to m, a washing step for washing the mowed young leaves by washing with water, a salt of 0.2 to 3% by weight with respect to the weight of water, and 0.2 to
3% by weight of baking soda was added, mixed and stirred, and heated, and the washed young barley leaves were added to the heated mixed solution in an amount of 10 to 25% by volume with respect to the volume of the mixed solution to perform heat treatment. A heat treatment step of, a cooling step of immediately cooling the heat-treated barley leaf with cold water, and dehydration of the cooled barley leaf with a centrifuge, and further dehydration of the dehydrated barley leaf with a drier. Dehydration to dry to 5% or less
It is said to be produced by a drying step, a pulverizing step of finely pulverizing the young barley leaf dried in the dehydration / drying step with a stone mill to form a powder, and a sterilization step of sterilizing the young barley leaf powdered in the pulverizing step. The problem was solved by adopting means.

[0006]

According to the present invention having the above-mentioned constitution, the young wheat leaves are heat-treated with hot water in which salt and sodium bicarbonate are mixed with water in the heat treatment step, so that the young wheat leaves are not decolorized and become powdery. It also retains a vivid light green or dark green color and prevents aging.

[0007]

EXAMPLE An example of the method of the present invention will be described. The method of the present invention comprises a cutting step, a washing step, a heat treatment step, a cooling step, a dehydration / drying step, a crushing step and a sterilization step. The steps will be described in detail below. In the method of the present invention, wheat includes wheat, barley, rye, and oats.

First, in the cutting step, young barley leaves, which are raw materials and have a height of 30 to 40 cm, are cut off. In this step of cutting young wheat leaves, there is no particular limitation, but it is recommended to use a grass cutting machine that preferably cuts grass.

Next, a cleaning process for washing the cut young wheat leaves with water is started. This washing step is a step of introducing the cut young wheat leaves into a water tank and washing with water to remove foreign matters such as mud.

After the cleaning process is completed, the next heat treatment process is started. In the heat treatment step, a large amount of water is put in a large heating pot, and 0.2 to 3% by weight based on the weight of water,
Preferably 0.5 to 1.0% by weight of salt and 0.2 to 3% by weight, preferably 0.5 to 1.0% by weight of baking soda with respect to the amount of water are added, mixed and stirred and heated. Then, 10 to 25% by volume of the young barley leaf washed in the washing step is added to the heated mixed solution to heat-treat it. The reason why the salt and baking soda are mixed with water is to prevent the temperature of the heated water from decreasing and to keep the color of the young wheat leaves vivid. 90 ~ 100 ℃ after adding young barley into the mixed solution in the heating kettle
And heat for about 1-5 minutes. In this heat treatment step, the enzyme is inactivated to prevent the powdered barley leaves from changing over time.

Then, in the heat treatment step, the heat-treated young wheat leaves are taken out of the heating pot and immediately enter a cooling step. In this cooling step, the heat-treated young wheat leaves are immersed in cold water of about 2 ° C to 7 ° C placed in a cooling pot for about 2 to 5 minutes to cool.

The cooled young barley leaves enter the next dehydration / drying step. In this dehydration / drying step, the heat-treated young wheat leaves are taken out from the heating pot, put into a centrifuge, dehydrated for 30 seconds to 1 minute to remove a certain amount of water, and then removed from the centrifuge to some extent. The dehydrated barley leaf is taken out and put into a dryer, for example, a dryer equipped with a rotating drum, and the temperature is set to 65 to 85 ° C., preferably 5 to 80 ° C.
It is dried for about an hour and dried to a state where the residual water content on young wheat leaves is 5% or less.

By the dehydration / drying process, the residual water content is reduced to 5
The barley leaf dried to a state of not more than%, enters the next crushing step. That is, in this pulverizing step, the dried young barley leaves are finely pulverized with a stone mill to a state of 90% 200 mesh to obtain a powder.

After the crushing step, the sterilizing step which is the final step is started. That is, in this sterilization step, the crushed and powdered barley leaf is sterilized by instant sterilization by microwave or a sterilization method such as steam sterilization to obtain a barley leaf powder as a final product.

The appearance and properties of the powder of young barley leaves obtained by the above process are light green or dark green powder and have a scent unique to young barley leaves similar to matcha.

Table 1 shows the result of analysis of young barley leaves powdered by the method of the present invention.

[0017]

[Table 1]

From the above analysis results, it was proved that the barley young leaf powder is rich in vitamins, minerals, proteins and chlorophyll, and also rich in dietary fiber. Since the components of the young barley leaves other than barley are almost the same as those of the barley young leaves, these powders are rich in vitamins, minerals, proteins and chlorophyll as well as the barley young leaf powders and rich in dietary fiber.

[0019]

The wheat barley powder obtained by the method of the present invention is rich in vitamins, minerals, proteins and chlorophyll as compared with other vegetables, and is rich in dietary fiber. In addition to improving bowel movements and preventing the development of colon cancer, it improves blood flow and prevents arteriosclerosis. Moreover, since it retains a light green color or a dark green color, it is beautiful and does not change with time.
Furthermore, since it is a powder, it can be easily used for cooking and drinking, it can prevent the nutritional imbalance of those who dislike vegetables, and it is extremely easy to ingest calcium, which tends to be insufficient, from the daily diet. It has an excellent effect of being able to.
