Description

Small Patches and Gels for Rice Worm Control

The present invention relates to a small patch and gel for rice bug control excellent rice control effect.

Today, international rice production is growing at an average annual rate of 3%, and in 2006, the output was about 416 million tons. In addition, the world's consumption of rice as population and income is increasing every year, and has been increasing at an annual average of 2.9% over the past 30 years. Therefore, the demand for paper packaging for rice is expected to increase continuously with the increase of rice production and consumption, thanks to the increase of rice production and consumption.

However, in the case of Korea, rice consumption is on the decline due to the generalization of western-style diet as income increases, and rice cultivation area has decreased due to the continued harvest and the increase of rice import. Is exceeding the appropriate level. This increases the cost of inventory for the storage and management of accumulated inventory, and reduces the selling price of rice due to various factors such as moisture, bacteria, insects, etc. that reduce the quality of the rice during storage, especially in hot and humid environments. The growth of rice worms such as Sitophilus oryzae, Tenebroides mauritanicus, and Plodia interpunctella caused by exposure to water increases the moisture content of storage rice and induces the growth of mold and bacteria.質) to fall. In addition, since it is easily identified with the naked eye, the rice is often discarded by increasing the psychological rejection of the stored rice, which increases the cost of storing and managing the inventory and lowers the selling price, thereby reducing the profits of the rice producers. Therefore, storing rice under appropriately controlled temperature and humidity conditions is the best way to control rice worms. However, if the rice is stored under too dry conditions (moisture 9% or less) in order to prevent the occurrence of rice worms, the water content of the rice itself is excessively reduced, causing the rice taste to drop. Therefore, in order to control rice worms, it is important to store the rice under controlled conditions of temperature and humidity, but since it is difficult to control such conditions in general homes, rice worms are easily exposed to the environment. In general households, rice can be used to control the temperature and humidity of rice to prevent pests from growing and inhabiting, but this method is a secondary approach, so the primary approach is necessary.

On the other hand, allicin (allicin), which has a spicy taste among garlic's representative components, is produced by decomposing allin, which is produced when grinding garlic, by an allinase, which is dissolved in ethanol at room temperature, When combined, it turns into another thirty different sulfur compounds. These allicin components express very strong bactericidal powers. Also, capsaicin, which has a pungent taste of red pepper, is used as a repellent for harmful animals of mammals, and is used as a pest control agent in the garden or at home. Toxicity of these capsaicins is expressed through metabolic disturbances, membrane damage and nervous system dysfunction, which in turn combats or kills pests.

When applying the inherent characteristics of the garlic and pepper as described above for the production of rice patch packaging for insect control is thought to be good rice control effect. Therefore, there is a need for developing a patch for controlling rice worms using garlic and red pepper.

The inventors of the present invention studied rice patch control packages using the unique properties of garlic and red pepper, while immersing the absorbent natural pulp pad made of natural fibers in a natural material solution containing a mixture of garlic juice and red pepper juice.

Hereinafter, the present invention will be described in detail.

The natural patch for controlling rice worms according to the present invention is to mix a mixture of garlic juice and red pepper juice in 5 to 10% by weight of starch solution at the same weight as the starch solution, that is, to immerse the natural fiber pad therein. It features.

The starch preferably comprises one or more selected from the group consisting of corn starch, waxy corn starch, potato starch, rice starch, wheat starch, tapioca starch, sweet potato starch and cassava starch, but is not limited thereto. The starch may be prepared by oxidation or cationic modification treatment on the starch, and may be obtained according to a conventional method in the art. The starch preferably comprises 5 to 10% by weight in a cationic or starch oxide solution. If the starch is less than 1.0% by weight, the effect of the rest of the composition is hardly expressed, and if the weight is more than 50%, the penetration effect into the inside of the natural fiber is reduced.

The garlic juice and red pepper juice have a rice worm control effect, the mixture of the garlic juice and red pepper juice preferably comprises 20 to 50% by weight of the rice worm control patch. If the garlic juice and pepper juice mixture is less than 5% by weight rice bug control effect is lowered, there is a problem that the rice bug survival rate increases. In addition, the garlic juice and pepper juice mixture is preferably mixed in a weight ratio of 5: 5.

The garlic juice is an extract separated from garlic, and it is known that allicin (allicin) made by the enzyme action of allinase on allin in garlic contributes to controlling rice pests. It is known to be toxic to pests and microorganisms. Garlic is a vegetable that can be supplied almost annually because its storage capacity is about 79%, and it is an essential seasoning for the Korean people's diet. Garlic's irritants are allyl sulfide and allyl phopyl sulfide, which are 1.5 times more potent than phenol. Garlic also promotes blood circulation and is good for sweating, diuresis and sterilization. It is also good for cold, anemia and hypotension. In addition, garlic contains various vitamins (A, B ₁ , B ₂ , nicotinic acid amide, C) and substances with male and female hormonal action. The most water-soluble carbohydrate, fructosan, is a fructosan polymer, with 70% of the most water soluble carbohydrates, 20% protein, 30% fibrin, 3.4% ash, and 0.1% yield. Produces an odor essential oil. In addition, the odorless precursor allin is a water-soluble crystalline substance that does not exhibit antimicrobial action, but grinding the garlic is a condition that can act on allin. At this time, allicin is influenced by enzymes in water and air, and water-soluble allicin is produced by oily secondary products which are characterized by village odor from water-soluble allicin under the influence of enzymes in water and air. Allicin is produced by enzyme action for self defense in the event of pest attacks on garlic. In terms of chemical structure, volatile products are diallyl disulfides, which are sulfides represented by the general formula C ₃ H ₅ -SH-C ₃ H ₅ .

The red pepper juice is an extract separated from red pepper, and the pungent, stimulating taste of red pepper is due to capsaicin, which is an active ingredient of red pepper. In order to prevent damage caused by rice worms in Korea or foreign countries, peppers are placed in rice storage places to prevent rice worms from occurring. This rice bug control effect is known to be due to the capsaicin component contained in the pepper. Capsaicin is the active ingredient of peppers consisting of 8-methyl-N-vanillyl-6-nonenamide. These active ingredients are very irritating and direct contact with mammals, including humans, and a burning sensation at the point of contact. Pure capsaicin itself is known to be hydrophobic, colorless and odorless. Capsaicin is used as a repellent for harmful mammals and also as a pest control parasite in the garden or at home. Toxicity of capsaicin is manifested through metabolic disturbances, membrane damage, and nervous system dysfunction, which in turn kills or kills pests.

The natural pulp pad preferably includes at least one selected from the group consisting of woodfree paper, heavy paper, pulp paper, art paper, coated paper, kraft paper, photosensitive paper, carbon paper, mermaid paper, hanji paper, drawing paper, and toilet paper, but is not limited thereto. It doesn't happen. Since the natural pulp pad is in direct contact with the rice to be packaged, it is difficult to cause degeneration of the rice or affect the taste or smell of the person.

The patch for controlling rice worms in the present invention is a natural pulp pad finely pulverized by using a porous packaging bag such as non-woven fabric or Hanji so as not to be in direct contact with the rice or milled in a cotton form with a blender machine The pulp was packed.

The pad manufacturing method may be any method known in the art, and in the present invention, the immersion injection method is used to immerse and inject the natural material solution into the natural fiber pad.

In addition, the pulp portion after extracting red pepper juice and garlic juice is artificially dried to a water content of 10 to 20% through natural drying or artificial drying, and then mixed with red pepper and garlic flesh in a ratio of 5: 5 to 1 to 5 mm in diameter. The extruder was passed through a die to prepare a bead form and then put into a porous outer packaging container such as a non-woven fabric or Hanji to prepare a patch.

실시예 2. 쌀벌레 방제 실험Example 2 Rice Bug Control Experiment

Using the rice worm control patch of the present invention was to reduce the survival rate of the rice worms to determine the excellent rice worm control effect.

Rice worm control patch prepared in Example 1 and the rice worm control patch prepared in the same method without using natural materials in the method of Example 1 to test rice worm control performance as a comparison group (no treatment) Control experiments were performed.

After mixing 50% each of brown rice and milled rice in a package to make 170 to 200g each, add about 40 to 60 rice weevils, and using natural fiber pads treated with natural materials. Each containing a patch, gel patch or rice worm control ring. After the rice weevil was put into a 34 × 24cm kraft paper bag, and left for 25 days at 25 ± 5 ℃, 70 ± 5% conditions, the survival rate of the rice worms was measured at regular intervals. Survival rate of rice worms (%) is calculated as shown in the following formula and the survival rate of rice worms according to the natural patch for rice worm control is shown in Figures 1 to 3.

In addition, in order to prevent the excessive natural smell of the pad of rice worm control, natural herbal lavender liquid was added to 1 L natural ingredients in 0.05 to 0.1 g units to test the rice worm control effect.

As shown in Figure 1, a natural patch for rice worm control prepared by immersing a natural pulp pad in a natural material solution mixed with a starch solution and a natural product in a ratio of 5: 5 or 3: 7 is not treated with no patch Unlike the group, when 6 days, 10 days, and 15 days elapsed, the survival rate decreased steeply regardless of the mixing ratio between the natural preparation and the starch solution.

In addition, it was confirmed that even after 6 days, 10 days, and 15 days, the rice worm control patch to which the natural herb solution was added showed a better control effect than the rice worm control patch to which the natural herb solution was not added. Although there are some differences, the longer the storage period, the lower the survival rate of the rice worms, and thus, the rice worm control patch added with the natural herb solution also confirmed that the rice worm control effect was excellent.

As shown in Figure 2, using a gel patch prepared by putting a high-density starch solution and a natural formulation in a ratio of 5: 5 to a non-woven fabric or a Korean paper was confirmed rice worm survival rate over time. The rice worms in the rice patch with the gel patch were killed rapidly after 5, 10, 15, 20, and 25 days, unlike the untreated group without the gel patch. there was.

As shown in Figure 3, using a gel patch prepared by mixing the garlic and red pepper flesh in a ratio of 5: 5 rice worm control ring in a non-woven fabric or Hanji was confirmed rice worm survival rate over time. The rice worms in the patched rice wrapper decreased in survival after 1, 3, 6, 8, 12, 15, and 18 days, unlike the untreated patch (untreated group). It could be confirmed that it dies quickly.
