It relates to a method of growing long-rooted green bean sprouts.

Soybean is a legume native to Manchuria and has been cultivated in Korea since the 4th to 5th centuries BC, and has been used as a food source of various protein sources such as soybean oil, tofu, soybean milk, and bean sprouts. In particular, bean sprouts are soaked in water and then put on rice straw or under the rice cooker, and then put the beans on it in a dark place at high temperature and humidity to germinate. Water frequently so that it does not dry out, and it has been used for cooking when it grows to about 5-7 cm. Bean sprouts in Korea are rich in protein, amino acids and vitamins, are inexpensive, and can be supplied year-round, so they are a traditional Korean food that is widely used in the people's diet.

Recently, the cultivation of bean sprouts has rapidly changed to mass production in automated facilities, including cultivation, production and packaging, as mass demand is created due to the recent growth of the catering industry and group catering. Bean sprouts are important vegetables that can be cultivated in a short period of time and have excellent nutrition and functionality, and are widely used at around 500,000 tons per year. Bean sprouts contain inorganic and essential nutrients necessary for the human body and thus occupy an important position as a food in Korea and are in high demand. Currently, it is estimated that there are about 4,000 bean sprouts producers in Korea that produce and sell about 700 billion won a year.

The heads of bean sprouts are usually yellow. This is because the bean sprouts are grown semi-hydroponically in a dark room and shipped when they are 5-7 cm tall. The green color of plants depends on the chlorophyll produced through photosynthesis. In other words, if bean sprouts are produced in a growing room with light instead of in a dark room, the hair of the bean sprouts will turn green, and the nutritional content will be different accordingly. The reason bean sprouts are grown in the dark is for soft cultivation, which is to suppress photosynthesis during plant growth so that soft tissues are well developed due to less fibrous tissue, and soft texture is cultivated in a dark room to increase the amount of water. say

However, it can be seen that green bean sprouts that do not suppress photosynthesis can be produced so that they can consume better nutrients than soften the texture in that the soft-cultured bean sprouts have reduced photosynthesis and thus reduced nutrients. . Compared to softly cultivated bean sprouts, green bean sprouts contain 1.4 to 25 times more of most nutrients such as isoflavones, aspartic acid, dietary fiber, calcium, and vitamins, so they are valuable for ingesting necessary nutrients.

In addition, aspartic acid is a representative nutritional component of bean sprouts. Aspartic acid is a type of acidic amino acid, and it is not an essential amino acid needed by the human body. However, as an important amino acid involved in both the TCA cycle and the ornithine cycle, it is known to the public to be good for hangover relief. Therefore, haejang foods using bean sprouts, such as bean sprouts haejangguk, take advantage of the characteristics of aspartic acid. Such aspartic acid is contained in a large amount in bean sprouts, and is especially concentrated in the roots of bean sprouts.

Based on the above facts, in the present invention, in order to cultivate bean sprouts rich in nutrients, the hair of the bean sprouts is green through photosynthesis, and the growth of the root part of the bean sprouts is improved so that bean sprouts with excellent nutrients can be cultivated. I would like to present a method for growing root green sprouts.

The long root green bean sprouts cultivation method of the present invention is largely divided into a soaking step, a watering cultivation step, a hydroponics step, and a harvesting and packaging step.

At this time, the watering step is a step to obtain long-rooted bean sprouts, and the hydroponics step is a step to obtain green sprouts through photosynthesis.

Existing bean sprouts cultivation does not go through the process of photosynthesis for soft cultivation, but the present invention supplies light so that the bean sprouts can photosynthesize in the hydroponics stage to further enrich the nutrients of bean sprouts through photosynthesis.

At this time, if the whole process is configured to be photosynthetic, the dietary fiber content is high and the texture is not good, so light is excluded in the watering cultivation step, so that some steps are softened cultivation.

In order to achieve the object of the present invention, beans for growing bean sprouts are soaked in water at a temperature of 16 to 20° C. and subjected to a soaking step called for 3 hours. At this time, the soaking time of the beans can be adjusted to 2-3 hours depending on the season.

Thereafter, the soaked soybeans are transferred to the cultivation container (10). As shown in the photo of FIG. 2 , the cultivation vessel has a plurality of through holes on the bottom so that the bean sprouts grow downward as shown in the photo, and there are also a plurality of through holes on the side to prevent the bean sprouts from decaying during cultivation, thereby improving ventilation. When the soaked beans are placed in a cultivation container, the beans are not able to escape downward because the beans are larger than the through hole of the lower part of the cultivation container, and thus the beans are accumulated. The size of the through hole is such that the bean cannot escape downward, but when the bean sprout grows, it has a size that allows it to grow while passing through the stem and the root through the hole.

In many existing methods of growing bean sprouts, drainage holes are designed to allow water to drain out. However, in the existing cultivation methods, only water escapes, but stems and roots grow upwards on the floor, so it is difficult to grow with the load of the sprouts themselves. Bean sprouts compete with each other and grow upwards, but there is a limit to the length of the stem and root that grows during the same time.

However, when the stem and root grow downward as in the present invention, bean sprouts having a much longer stem and root can be obtained because the stem and root extend in the direction of gravity instead of growing while supporting themselves as in the previous method.

Since aspartic acid, the main nutrient of bean sprouts, is concentrated in the root part, long-rooted bean sprouts that are nutritionally superior to general bean sprouts can be obtained by cultivating them to grow long as described above.

In addition, for the same reason as above, when the amount of beans increases compared to the total area of the floor, it is difficult for the stem and roots to escape through the through hole as the bean sprouts grow because the through hole in the lower part of the cultivation container is blocked by the bean. Be sure to stack the beans in two or less layers when storing.

A frame 20 for stacking cultivation containers in a culture chamber blocked from light, a nozzle for supplying water from the upper part of the stacked culture container, and a plurality of spray holes 22 to evenly spray water from the nozzles A water storage tank 30 is positioned at the bottom of the raised upper plate 21 and the stacked cultivation vessel so that water flowing out of the cultivation vessel can be stored. The nozzle supplies water over the top plate positioned at the top of the loaded cultivation vessel, and controls water to be supplied at intervals of 2 hours for 5 minutes. The water supplied over the top plate is evenly sprayed on the bean sprouts in the cultivation vessel under the top plate through a plurality of injection holes 22 drilled in the top plate. At this time, the temperature of the cultivation room is maintained at 18 ~ 22 ℃ lower than room temperature so that the bean sprouts can grow best, and a pump 31 is provided in the storage tank so that the water supplied from the upper part of the cultivation container and the water of the storage tank are continuously circulated. do. In addition, an underwater heater 33 and a cooler 32 are additionally installed to keep the water temperature constant at 16 to 20° C. so that the bean sprouts can grow uniformly. In the past, a method was used that did not reuse water while directly using groundwater or tap water. However, in this case, the growth rate of bean sprouts is irregular because water with a non-uniform temperature is supplied to the bean sprouts, so the growth rate is irregular even when grown under the same conditions. phenomenon occurs. Therefore, while water is reused, temperature control devices such as coolers and water heaters are installed to keep the water temperature constant and to make the growth rate of bean sprouts uniform.

After growing bean sprouts for more than 96 hours through the watering cultivation step in the cultivation room, the stems and roots of the sprouts coming out from the bottom of the cultivation container are checked and then transferred to the hydroponic cultivation room. In the hydroponics room, while growing bean sprouts hydroponically, they have a rich nutritional value through photosynthesis and make the hair of the bean sprouts green. A general hydroponics method is to put water in a large tank or let it flow, and place the cultivated plants on it so that the cultivated plants grow using the supplied water.

However, in this method, when water is contaminated or exposed to diseases, it is rapidly transmitted to all cultivated plants, making it difficult to respond, resulting in greater damage. In order to solve this problem, in the cultivation method, one tank corresponds to one cultivation container by using a tank 40 of a size similar to that of the cultivation container.

In addition, since the water tank is independent for each growing container, even if a disease occurs during hydroponics, there is little risk of transmission to the bean sprouts in other cultivation containers. Therefore, even if a disease occurs in the tank or the water is contaminated, it can be easily dealt with by separating only the tank from the cultivation container.

Place the bean sprouts transferred from the cultivation room on the water tank as a cultivation container. By using the multi-layered shelf, it is possible to grow a large amount of bean sprouts in a narrow space, thereby improving the yield per space. In addition, the shelf can be easily moved even in a state in which the cultivation vessel is loaded using four wheels attached to the bottom.

The water tank is independently located in each cultivation vessel, and when the cultivation vessel 10 is disposed on the water tank 40 as shown in FIG. 4, the lower portion of the cultivation vessel and the lower portion of the water tank are separated by a certain distance or more. The container is configured in a rectangular shape gradually narrowing toward the bottom, and the upper edge of the water tank is the same size as the side of the cultivation container at a certain height.

In addition, the water tank is selected with a transparent or translucent material so that the growth state of the bean sprouts escaping from the lower part of the cultivation container can be easily checked with the naked eye and dealt with. Water is supplied to the water tank at a water temperature of 16 to 20 ° C at a water temperature of 16 to 20 ° C, separated by 2 to 3 cm from the bottom of the cultivation container, and selected from sunlight, shade, LED, etc. . At this time, since the cultivation container is loaded on the shelf in multiple layers, when natural light is used, light is supplied only from the top of the shelf, and thus the amount of photosynthesis of the bean sprouts in the cultivation container located at the bottom of the shelf is inevitably reduced.

Therefore, it is desirable to supply light not only from the top but also from the side using LED lights so that all cultivation vessels can photosynthesize evenly. In this case, bean sprouts can be mass-produced using many cultivation vessels in a narrow space and the light supplied from LEDs Since it has a constant illuminance, it can have a uniform quality.

In addition, the shelf on which the cultivation container is loaded is equipped with wheels at the bottom, so that the cultivation space can be easily replaced according to the situation. Since natural light has a different illuminance depending on the weather, so the efficiency is not constant, it is possible to properly mix natural light and artificial light such as LEDs for photosynthesis.

In addition, desired additives such as sugar, fruit juice, red ginseng liquid, oriental medicine decoction water are mixed in a certain ratio with the water supplied when water is supplied to the water tank to improve the nutritional component of the bean sprouts or to add a desired flavor.

As described above, after installing the cultivation container for photosynthesis in the hydroponic cultivation room supplied with the desired light source, the bean sprouts are harvested from the cultivation container after 48 hours.

Nutrient-rich long-rooted green bean sprouts harvested through the above steps are washed under running water and vacuum-packed to prevent deterioration and maintain freshness for a long time before shipping.
