Description

A growing method of bean sprouts containing polyphenols

The present invention relates to a cultivation method of soybean sprouts containing a polyphenol component, and in particular, an aqueous solution of polyphenol extracted from oak with water is sprayed sufficiently during the process of soybean germination and growth into bean sprouts. The present invention relates to a cultivation method of bean sprouts containing polyphenols that can promote growth to provide a sufficient nutrient source.

In general, bean sprouts are grown by soaking soybeans in water, germinating them in growth containers, and periodically supplying water.

However, such a general method of cultivating bean sprouts provides an environment in which bacteria that inhibit the growth of bean sprouts can proliferate, causing black spots on the head of the bean sprouts, or decaying roots or stems. Or, there is a problem in that the quality of the bean sprouts are lowered and the yield is reduced by bruising the stems to suppress the growth.

In order to improve such a problem, conventionally, pesticides were mainly used, but recently, various methods of growing using natural fungicides harmless to the human body have been proposed because of the problem that the pesticides remaining in the cultivated beans or water are harmful to the human body.

In addition, conventionally, bean sprouts sterilize and swell beans, such as beans, green beans, and red beans, seeds of sunflower and broccoli with hypochlorous acid or high temperature water, and spray groundwater several times a day. After germination and growth, it has been provided to consumers. Such bean sprouts contain little vitamin C in the state of soybean as a raw material, but when sprouted and become a state of bean sprouts, they contain vitamin C. In addition, they contain carbohydrates and proteins, and are widely used as food for nutrition. Is being provided.

However, since the disinfection and sterilization by hypochlorous acid, which is carried out in most bean sprouts manufacturing plants, includes chlorine, the effect on the health of not only consumers but also the producers, the corrosion of the equipment in the plant, and the treated water containing chlorine. It is expected to become a social problem in the near future, such as the fact that it is produced as it is. In addition, because of the long growing period, there is a lot of corruption, and despite the fact that the daily production does not increase, there is no progress in the study on the shortening of the growing period. Therefore, there is a need for a method of sterilization that is safe for the health of consumers and manufacturers and a technology that can shorten the growing period.

In addition, a significant portion of the health-enhancing ingredients contained in legumes are consumed during germination and growth and, in addition, because they are grown in cows, the synthesis of new substances is less, making them less nutritious than conventional green vegetables. have. Therefore, despite being influenced by the change of the weather, being cultivated regularly and contributing to the daily diet, it is sold at an extremely low value.

In view of such circumstances, the present inventors are researching a method for growing soybean sprouts containing a large amount of nutrients such as polyphenols and vitamin C, which are contained only in a small amount in bean sprouts, but are known to be effective in antioxidant and gastric cancer. have.

The present invention has been made to solve the above requirements, and an object of the present invention is to provide a bean sprout cultivation method that can promote the sterilization and growth of bean sprouts using natural materials beneficial to the human body.

In addition, at the same time there is another purpose to contain the essential nutritional ingredients using natural ingredients during the cultivation process of bean sprouts.

Therefore, the present invention can absorb the polyphenols and bean sprouts at the same time while ingesting soybean sprouts, so that other nutrients can be ingested, so that the polyphenols extracted from the oak during the process of germinating beans and growing beans It is to provide a method of cultivating bean sprouts containing a polyphenol component so that a large amount of polyphenol components in the sprouts by sprinkling the aqueous solution diluted with water.

According to the cultivation method of the bean sprouts contained in the polyphenol component according to the present invention as described above, by inhibiting the growth inhibition by the sterilizing power of the polyphenol aqueous solution, the content of trace elements is high and the appearance is the same as the conventional sprouts It is possible to grow soybean sprouts containing more substances useful for health promotion and to adsorb and remove pesticides or heavy metal components remaining in soybeans by adsorbing and removing particulate matters by sprinkling aqueous polyphenol solution. In addition, by adsorbing and removing microorganisms harmful to germination and activating microorganisms that are beneficial to germination, they not only promote the growth of bean sprouts, but also absorb high amounts of various vitamins and minerals to provide high-quality bean sprouts containing nutrients evenly. It can be served, and the rich flavor of oak is soybean Blending well with the inherent flavor of the herbs (香 보다) to be able to produce more delicious bean sprouts, such as to increase the external competitiveness of the bean sprouts to the maximum.

Looking at the polyphenol extraction process extracted from the oak used in the present invention for achieving the above object is as follows.

Extraction solvent containing oak wood chips and hydroxyl group (-OH) in airtight container in a sealed container under saturation condition, pretreatment time 30 seconds or more and less than 12 hours, treatment temperature 50 ℃ or more and less than 400 ℃, pressure 1kgf / cm2 or more and less than 100kgf / cm2 Conditioned, oak polyphenols undergoing the general procedure of extracting the pretreated wood at 120 ° C. for at least 15 minutes at a high temperature of less than 60 minutes, followed by filtration and separation purification to produce extracts containing polyphenol components. An extract is prepared.

In addition, instead of the polyphenol extract extracted from the oak, the dry powder of mugwort was suspended in water, and 4 ppm of pectinase, a pectinase, was added to enzymatically treat the suspension, and then 30 to 90 minutes at 50 to 70 ° C. After the reaction with stirring for a while, hot water extract for 30 to 90 minutes at 90 ~ 100 ℃, and to produce a polyphenol extract from the mugwort comprising the process of obtaining a liquid polyphenol extract by filtration.

In addition, put the raw pine needles in the steamer instead of the mugwort steamed for 30 to 90 minutes at 50 ~ 80 ℃, and then to the enzyme treatment of the steamed pine needles 4ppm pectinase and 1.5% (w / v) red pepper extract was added and reacted with stirring at 50-70 ° C. for 30-90 minutes, followed by hot water extraction at 90-100 ° C. for 30-90 minutes, followed by filtration to obtain a polyphenol extract as a liquid component. The polyphenol extract is prepared from raw pine needles comprising the process.

When the red pepper extract is treated with the pectinase, it can be seen that the extraction yield of the polyphenol shows a synergistic effect. When the red pepper extract rich in vitamin C having the antioxidant effect is treated, the extract is extracted. Since the oxidation of the sugar present in the is prevented, the browning of the extract is suppressed, resulting in an increase in the content of the reducing sugar, as well as can increase the extraction yield of polyphenols. At this time, the treatment amount of red pepper extract is not particularly limited to this, it can be seen that it is preferable to treat in an amount of 1.0 to 1.8% (w / v) with respect to fresh pine needles. When the amount was less than 1.0% (w / v), the content of reducing sugar was not increased in comparison with the untreated red pepper extract. The content of reducing sugar was increased in proportion to the amount, and it was found that the content of reducing sugar was no longer increased when treated with an amount greater than 1.8% (w / v).

That is, the present invention, as shown in the process block diagram of Figure 1, first to wash the raw beans to be used in advance one day, and then to sort the washed beans stored at 6 ~ 8 ℃ low temperature to remove the surface moisture, The quality of the beans themselves is kept below 10 ℃. At this time, the washed soybeans will contain moisture in the inside will be slightly soft.

After washing and sorting, the first step of performing a process called 4-6 hours in a polyphenol aqueous solution in which water and oak polyphenol extracts were diluted at a ratio of 500: 1 on day 1 of the beans stored at low temperature;

A second step of spraying ground water having a temperature of about 16 to 18 ° C. in a planting room at 20 to 25 ° C. on a second day after subdividing so as to remove water from the beans after the first step;

Next to the second step, the sprouts are grown through the third step of spraying the polyphenol aqueous solution diluted with water and oak polyphenol extract at a ratio of 500: 1 on the 3rd to 5th day.

From the third step 6 days through the process of repeatedly performing the second step it is possible to obtain the bean sprouts according to the consumer's propensity from the young bean sprouts to the grown bean sprouts according to the date.

In the process called raw soybeans as described above, the temperature is closely related to the growth of bean sprouts. In order to ensure that the bacteria and fungi in the bean itself are suppressed as much as possible in the bean sprout growth process, the soybean temperature and soaking time of the polyphenol solution in the soaking process should be followed to maximize the effect of the yield of polyphenols in the bean sprouts.

By spraying the aqueous polyphenol solution on the 3rd to 5th days of the growth process, it is possible to minimize the onset of inhibiting the growth after cultivation, and to prevent the onset and maximize the effective polyphenol component to remain in the bean sprouts.

In particular, the present invention can be maximized in the antimicrobial effect and polyphenol yield content for germinating bean sprouts by spraying the polyphenol aqueous solution 1 to 3 times before the ground water is sprayed on soybeans.

In addition, after the first step, by placing the soybeans on the germination medium (barley sprout powder + non-woven fabric) containing the barley sprout powder may further comprise the step of cultivating germinated beans of 1 ~ 3.5cm, In the germination process, it is preferable to spray water at intervals of 4 hours using ground water for water spraying.

Natural antioxidants such as vitamins A, C, D, E, K and Se (selenium) contained in the barley sprouts have SOD (Active Oxygen Sanctions) that develops the power to overcome harmful environmental hormones such as dioxin. In the process of adsorbing the nutrients contained in the barley sprout so as to sufficiently include such components in the bean sprouts.

The process after the germinating step includes the above-described second step and then the step after the germination step except for the sequential date is calculated by applying the same day by day.

For this reason, the bean sprouts containing the polyphenols grown according to the present invention not only contain aspartic acid, carotene, thiamine, vitamin A, which are contained in general bean sprouts, but also contain polyphenols such as oak. Allows you to eat with phenols. According to various studies, since the polyphenol component has cholesterol suppression effect, blood pressure increase inhibitory effect, and antioxidant effect, the same effect can be expected in bean sprouts containing polyphenols grown according to the present invention.
