Description

The manufacturing method of barley leaves flour

The present invention relates to a method for preparing barley leaf powder, and more specifically, to barley leaf extract by extracting barley leaf extract at a predetermined temperature by adding water to the dry barley leaf, and concentrating it under reduced pressure, lyophilizing and grinding to prepare barley leaf powder. By adding it to foods such as noodles, bakery, drinks, etc., or using it as a soap material, many vitamins and sodium, potassium, calcium, magnesium, iron, copper, etc. Easily intake of essential elements, anemia, constipation improvement, hepatic function enhancement, jaundice healing, detoxification, skin beauty, etc., not only improved the food value of barley food but also low-cost barley leaves To create high added value.

Barley is an annual herb and is cultivated for edible throughout the country. Barley is used not only for malt but also for various fields. Barley leaves are 775mg of sodium, 0.88mg of potassium, 1.08mg of calcium and 224.7mg of magnesium. , Iron 15.8mg, copper 1.36mg, etc. It is reported that it is effective in disaccharide and diuretic effect. Washing the hands and feet with frostbite and water with barley leaf was great effect.

In addition, young barley leaves are rich in vitamins, minerals, and chlorophyll, which help to detoxify the waste matter accumulated in the body. Healing hepatitis and cirrhosis improve liver function and help digestion.

In order to use these barley leaves in real life, young barley leaves that have been passed over the winter were collected from March to early April, washed well, and then used in the shade and crushed. When used, the texture of the food is not good, and the texture of the soap is also lowered, which is inconvenient to use, and there are problems such as poor foaming.

In order to solve this problem, 'Functional fermented food using barley bran powder' of Korean Patent Publication No. 2002-73354 is prepared by fermenting barley bran powder to make meju, and fermented barley bran powder molded product (round, granule) However, by fermenting barley bran powder, there is a problem that the texture is lowered and the utilization of barley bran powder is limited. Another Korean Patent Publication No. 1997-5123 discloses the preparation of granules using barley young leaf powder and juice. Method 'simply used to finely grind the barley leaves, there was a problem that can not prevent the texture of food or the touch of soap is lowered.

Therefore, an object of the present invention is to simply add water to the dry barley leaves to extract the barley leaf extract at a certain temperature in order to solve the problems of the conventional barley leaf powder manufacturing method by simply crushing the barley leaf powder, Concentrated under reduced pressure, lyophilized and pulverized to produce barley leaf powder and added to foods such as noodles, bakery, drinks, etc., or as a soap material, many vitamins necessary for the human body without deteriorating the texture of the food and texture It can easily consume essential elements such as sodium, potassium, calcium, magnesium, iron, and copper, and has an excellent effect on anemia, constipation improvement, liver function enhancement, jaundice healing, detoxification, skin care, and barley food. Barley leaf powder that not only improves the scientific value but also enables the creation of high added value by using barley leaf at low cost. It is a method to provide.

Barley leaf powder production method of the present invention for achieving the above object, the step of collecting the winter barley leaves and washed three to four times with distilled water (S1); Drying the washed young barley leaves for 72 to 96 hours (S2); Adding 80-90 wt% of water to 10-20 wt% of the dry barley leaves and extracting the barley leaf extract for 4-6 hours at 65-98 ° C. (S3); Concentrating the extracted barley leaf extract at 45-55 ° C. under reduced pressure (S4); Lyophilizing the concentrated solution under reduced pressure at -10 to -5 ° C (S5); It characterized in that it comprises a step (S6) of grinding the lyophilized dry matter to a particle size of 150 ~ 300mesh.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings such that those skilled in the art can easily implement the present invention.

In the accompanying drawings, Figure 1 is a manufacturing process of the barley leaf powder of the present invention, the configuration is washing (S1), shade (S2), extraction (S3), reduced pressure concentration (S4), freeze drying (S5) and grinding (S6) It becomes

First, the young barley leaves (10-15cm) overwintered and washed three to four times with distilled water (S1) to completely remove foreign matters, and then the young barley leaves are dried in the shade (S2) for 72 to 96 hours. Remove it.

When the shade time is less than 72 hours, the moisture contained in the barley leaves is not sufficiently removed, and when the shade time exceeds 96 hours, the shade is poor for 72 to 96 hours (S2).

Water is added to the dry barley leaves and barley leaf extract is extracted (S3), but if the blending ratio of the dry barley leaves is less than 10% by weight, the concentration of the extract is lowered and the productivity is not good. Since the concentration does not increase, it is preferable to add 80 to 90% by weight of water to 10-20% by weight of dry barley leaves.In addition, if the extraction temperature is less than 65 ° C, extraction is difficult. Therefore, it should be extracted for 4 to 6 hours at 65 to 98 ℃.

In addition, when the mixture is extracted by adding a mixture of water and alcohol to the barley barley leaves, it is possible to elute both the water-soluble components and fat-soluble components contained in the barley leaves, the compounding ratio is extracted in a 85:15 volume ratio.

Concentrate the extracted extract under reduced pressure (S4) to produce a concentrate. At this time, if the concentration temperature is less than 45 ℃ time is increased when the concentration is not good, and if the productivity exceeds 55 ℃, excessive energy is required, 45 ~ 55 ℃ Concentrate by slowly depressurizing in the temperature range.

The concentrated concentrate is freeze-dried (S5) at -10 to -5 ° C to obtain a dried product having excellent plurality while maintaining the properties of the barley leaves. If the freezing temperature is less than -10 ℃, it is not economical much energy consumption, and if the freezing temperature exceeds -5 ℃, it is preferable that the freezing temperature is -10 to -5 ℃.

After freeze-drying, the lyophilized dry matter is crushed to a certain particle size (S6) so that it can be easily used in products such as food or soap, and the particle size of the dried product is 150-300mesh so that it is easy to use without being easily dispersed.

When barley leaf powder prepared by the above method is mixed with foods such as bread, noodles, ice cream and drinks, it is rich in nutrition and excellent in texture, and when used in bath products such as soap, the properties of the product are not deteriorated. It also contains barley leaves to ensure high quality products.
