A method for producing wheat young leaf powder, which comprises producing a wheat young leaf powder in the pulverizing step by sterilizing the wheat young leaf. Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powdery wheat leaf such as wheat, barley, rye, oat and the like, which can be used for cooking or beverages. The present invention relates to a method for producing wheat young leaf powder. [0002] Hitherto, there has been no known production method for powdering wheat young leaves such as wheat, barley, rye and oat. [0003] Conventionally, there has been a technique for pulverizing wheat young leaves such as wheat, barley, barley, oats and the like into powder for use in cooking or beverages. As a result, there was a problem that barley young leaves rich in nutrients such as chlorophyll, vitamins, minerals, and dietary fiber could not be used. [0004] The present invention is to provide a method for producing wheat young leaf powder in which wheat young leaves such as wheat, barley, rye, oat, etc., which have not been conventionally used, can be powdered and used for cooking or beverages. It is assumed that. Means for Solving the Problems [0005] The present invention provides a cutting step of cutting wheat young leaves that have grown to 30 to 40 cm, a washing step of washing the cut wheat young leaves with water, and washing. 0.2 for
３3% by weight of salt and 0.2-3% by weight of sodium bicarbonate are added, mixed, stirred and heated.
And a heating treatment step in which the washed wheat young leaves are put into the heated mixed solution, and 10 to 25% by volume with respect to the volume of the mixed solution, and heat-treated at 90 to 100 ° C. for about 1 to 5 minutes ; A cooling step of immediately cooling the heat-treated wheat young leaves with cold water,
A dehydration / drying step of dehydrating the cooled wheat young leaves with a centrifugal separator and further drying the dehydrated wheat young leaves with a dryer until the residual water content is 5% or less;
A problem is caused by employing a means of producing by means of a pulverizing step in which the wheat leaves dried in the drying step are finely pulverized with a stone mill into powder, and a sterilizing step in which the powdered wheat leaves are sterilized in the pulverizing step. Solved the point. According to the present invention having the above-described structure, the wheat young leaves are heat-treated with hot water in which salt and baking soda are mixed in water in the heat treatment step, so that the wheat young leaves are not decolorized but powdery. In this case, a vivid light green or dark green color is maintained and a change with time is prevented. DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment 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 dewatering / drying step, a pulverizing step and a sterilizing step. The details will be described below in the order of the steps. In the method of the present invention, wheat includes wheat, barley, rye, and oats. First, in the cutting step, young wheat leaves that have grown to a height of 30 to 40 cm, which are raw materials, are cut. In the step of cutting wheat young leaves, it is not particularly limited, but it is preferable to use a pasture mowing machine that cuts pasture. Enter the cleaning process. This washing step is a step of throwing the harvested wheat leaves into a water tank and washing with water to remove foreign substances such as mud. [0010] After the completion of the cleaning step, a next heat treatment step is started. In the heat treatment step, a large amount of water is put into a large heating pot, and the amount of salt and water is 0.2 to 3% by weight, preferably 0.5 to 1.0% by weight based on the weight of water. 0.2 to 3% by weight, preferably 0.5 to 1.0% by weight of sodium bicarbonate is added, mixed, stirred and heated, and then heated in the mixed solution in the washing step. The washed wheat young leaves are added and heated at 10 to 25% by volume based on the volume of the mixed solution. The incorporation of the salt and baking soda in water-proof technique that the temperature of the heated water is lowered, the solution and alkaline
In addition , it is for keeping the color of wheat young leaves vivid. After throwing wheat young leaves into the mixed solution in the heating kettle, it is heated at 90-100 ° C. for about 1-5 minutes. In this heat treatment step, the activity of the enzyme that causes browning is removed by inactivating the enzyme.
To prevent the aging of the powdered barley young leaves. [0011] In the heat treatment step, the wheat leaves that have been heat-treated are taken out of the heating pot and immediately enter a cooling step of cooling. In this cooling step, the heat-treated wheat young 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. [0012] The cooled young wheat leaves enter the next dehydration / drying step. In this dewatering / drying step, the heat-treated wheat young leaves are taken out of the heating kettle, put into a centrifuge, and dewatered for 30 seconds to 1 minute to remove a certain amount of water. The dehydrated wheat young leaves are taken out, put into a dryer, for example, a dryer equipped with a rotating drum, and dried at 65 to 85 ° C, preferably at 80 ° C for about 5 hours, and the residual water content of the wheat young leaves is 5% or less. Dry to the state of. [0013] The wheat leaves that have been dried to a state in which the residual water content is 5% or less by the dehydration / drying step enter a next pulverizing step. That is, in this pulverization step, the dried wheat young leaves are finely pulverized with a stone mill to a state of 90% and 200 mesh to obtain a powder. After the pulverizing step, a sterilization step, which is a final step, is started. That is, in this sterilization step, the crushed and powdered wheat leaf is sterilized by instantaneous sterilization by a sterilization method such as microwave or steam sterilization to obtain a wheat leaf leaf powder as a final product. [0015] The appearance and properties of the wheat leaf powder obtained by the above-mentioned process are light green or dark green powder and have a unique flavor similar to matcha tea. Table 1 shows the results of analysis of powdered young barley leaves and young barley leaves obtained by the method of the present invention. [Table 1] From the results of the above analysis, it was proved that the powder of young barley leaves was rich in vitamins, minerals, proteins, chlorophyll, and also rich in dietary fiber. In addition, the components of barley young leaves other than barley are almost the same as those of barley young leaves, so that these powders are rich in vitamins, minerals, proteins, chlorophylls, and are also rich in dietary fiber, like the barley young leaves powder. EFFECT OF THE INVENTION The wheat young leaf powder obtained by the method of the present invention is rich in vitamins, minerals, proteins, chlorophyll and dietary fiber as compared with other vegetables, so that intestinal peristalsis. It can increase bowel movements, improve bowel movement, prevent colon cancer, improve blood flow, and prevent arteriosclerosis. In addition, since it retains light green or dark green in appearance, it is beautiful and does not change with time. Furthermore, because it is a powder, it can be easily used for cooking and drinking, it can prevent the bias of nutrition of those who do not like vegetables, and it is very easy to ingest calcium that tends to be insufficient from everyday diet The effect is excellent.
