Description

Functional packing sheet for rice during distribution {Functional packing sheet for rice during distribution}

The present invention relates to a functional rice packaging material that continuously maintains the taste and quality of the distributed rice for a long time, and in detail, it has a high viscosity and good binding to the pulp, which maintains freshness, antibacterial effect, deodorizing effect, and constant temperature and humidity control effect. As an excellent far-infrared radiation material, natural minerals of oak, biotite and elvan are added to ocher and mixed. It is an eco-friendly functional rice packaging material made of paper. It is excellent and has antibacterial, deodorization, and freshness retention effect due to the emission of far infrared rays, which makes rice easy to deteriorate due to deterioration, decay, and the occurrence of pests during distribution, without loss of taste, vitamins, carbohydrates, etc. A functional packaging that can be stored.

Grains continue to breathe while stored as living beings. Rice produced and harvested in Korea is hot-dried on the basis of approximately 15.5 ~ 16.5%, which is generally the best water taste in consideration of food taste, and then using a grain cooler exclusively for rice to maintain high quality taste and taste. It is stored in a medium-low temperature environment (10-12) where temperature and humidity are controlled to suit the characteristics of rice, and during this storage, rice, like other grains, continues its physiological activity such as respiration.

 In addition, rice is piled in a layer of insulated chaff, which can be protected from invasion of fungi or pests during storage, and removes rice and rice bran, which are reduced in volume by 20% through a process of removing rice husk husk from rice. White rice, which is the dominant type of distributed rice, is a kind of fresh food, which is sensitive to changes in external temperature and humidity, and is easily deteriorated and easily invaded by pests. There is a problem of poor quality such as rice taste.

In the processed rice, brown rice is about 2 ~ 4 days after processing and white rice is 1-2 days after being immediately packaged in the packing area of various packing units made of conventional general land or PE, Al, etc. It is usually distributed for a long time with an average storage period of 1 ~ 2 months, and the distribution environment after rice packaging is distributed at room temperature unlike fruits and vegetables operated by low temperature distribution system. In general, the indoor food store is left at a relatively high temperature and a relative humidity of 35 to 40% with an average storage temperature of 20 to 25 ° C. Due to deterioration, it is unable to supply high quality rice, which does not satisfy consumers' preference for rice with excellent taste and nutritional value. As it is not fundamentally alter the distribution of rice in cold chain system (cold chain) rice only packaging material that can maintain the quality of the rice in temperature distribution in the real environment, a period of time continue to develop urgently needed.

As mentioned above, as a reason for developing a rice-only packaging material that can maintain the quality of rice continuously for a certain period of time even in the room temperature distribution environment, high-quality rice generally means rice that has excellent appearance and good taste (flavor). The factor affecting taste is known as the moisture content when excluding varieties and degrees, but in order to maintain the optimal moisture content of 15.5-16.5% of rice with good taste, our people prefer temperature and temperature It is necessary to maintain a consistent environment without interruption of storage conditions to maintain the quality of rice because a low-temperature distribution environment where humidity is properly harmonized is required, but the reality is not.

As described above, the packaging materials used for conventional rice are 20kg and 10kg small and medium packaging materials, except for the plastic bags used for large packages of 40kg or more, and the PE or Al of kraft paper or synthetic resin material for each material. Among them, 20kg of land packaging materials occupy more than 80%, and PE or Al packaging materials are easy to rupture due to their low hardness and elasticity. There is a limit to the holding capacity. Until now, in order to maintain high quality rice, no special packaging material has been developed in consideration of the relative humidity and distribution temperature of rice, which is not developed by the packaging manufacturers or rice producers. It comes from the use of packaging materials that only concern the development of designs or cosmetic forms.

According to the report on the quality change of rice by packaging material during the distribution period reported to the Ministry of Agriculture and Forestry, the zone packaging material shows a high weight loss rate, resulting in economic loss and deterioration of rice taste due to rice drying. However, the weight loss is less than that of the zone packaging, but the taste decreases over time due to the increase in fatty acid value, which is an indicator of the flavour value, indicating that all of the currently used packaging materials are not suitable for use as rice packaging materials.

All the packaging materials currently in use are inadequate to be used as rice packaging materials. Zoned packaging equipment has a problem that the relative humidity in the packaging decreases due to high moisture permeability, resulting in a lot of weight loss and excessive drying, and PE packaging materials have elongation and water resistance. On the other hand, because of permeability according to thickness, moisture reduction and weight reduction are slower as the film thickness is thinner, and as the fatty acid value is thinner, the increase is smaller. Setting of the moisture permeability is required.

Packaging materials imparting PERFORATED to film materials used in vegetables and the like to increase the appropriate moisture permeability can be improved breathability, but when applied to rice packaging materials due to the characteristics of the film material, it can be applied to microbial contamination and pest propagation and porosity. Problems such as lack of strength and tensile strength of the packaging material were derived.

As a result, it is an environmentally friendly material that has been confirmed to be safe for plants in accordance with the characteristics of rice under the current distribution environment where proper humidity and temperature control is not achieved, and it is durable, breathable and antibacterial, Hygiene, cushioning, economical. Productivity and deodorization are harmonized evenly, and proper temperature and humidity control prevents deterioration and decay of rice and prevents the occurrence of pests. Therefore, the quality and quality of rice can be maintained for a certain period of time even during long-term storage or distribution. There is a need for a functional packaging material for rice that can be maintained.

As it is known, a spoonful of loess contains about 200 million microorganisms, which are called living organisms. Loess is a substance that emits a large amount of far-infrared rays, which are life rays that activate materials. Catalase, diphenol, oxidase, saccharase, It contains various enzymes such as protase and potassium carbonate, and contains various mineral particles such as quartz, feldspar, mica, calcite, 60-65% silica, 10-13% alumina, 5-6% iron, It has a chemical composition containing about 2% magnesium and potassium, about 8% lime, and is known to have a water content of 10-15% and a porosity of 50-55%. It has a bactericidal effect, activates the physiology of crops, absorbs decaying toxins, and has excellent temperature and humidity control functions. Enzymes of relevance hydratase has as being harvested is maximized when using the yellow soil for this is known as the enzyme Saqqara to the fact that the activity is proven byeona barley crops characterized in that to suppress the spoilage bacteria.

Traditionally, as mentioned above, examples of using ocher characteristics include long-term storage of grains or fresh crops in ocher earthenware, such as loess crypts or hanglari, to maintain freshness.

Jade (jade) is roughly divided into jadeite and jadeite, and the jadeite is monoclinic material and forms a dense mass like crystal. It contains a large amount of magnesium, and the energy of far-infrared rays emitted from the jade is beneficial to humans and crops.

Elvanite is a igneous rock composed mainly of silica and alumina, and contains inorganic materials such as iron oxide, kali, and manganese oxide. It has strong adsorptive power in addition to far-infrared radiation action, and it has good deodorizing and moisture-proofing effect and sterilization effect, and detoxifies heavy metal as porosity.

Biotite is composed of germanium, which emits a large amount of far infrared rays, has antibacterial, antibacterial, antifungal and harmful gas adsorption functions, and releases a large amount of anions. As a result of the experiment, germanium acts as an oxygen catalyst to help the efficient use of oxygen. Turns out.

In addition, as a support material, natural doc pulp is a strong fiber of bast fiber, and has high viscosity and strong binding ability, so as to contain red clay, jade and biotite powders which are far-infrared radiation materials.

The present invention has been made to solve the above-mentioned problems, it is to maintain the taste and quality of the distribution rice for a long time as a viscous and viscous good binding to the pulp pulp maintaining freshness, antibacterial effect, deodorizing effect, constant temperature and humidity It is a far-infrared radiating material with excellent control effect. It is mixed with natural minerals of oak, biotite, and elvan in the clay, and it is an eco-friendly functional rice packaging for papermaking. It has excellent cushioning properties, and has antibacterial, deodorant, and freshness retention effect due to the release of far-infrared rays, and it is easy to reduce the quality of rice due to deterioration, decay, and pests during distribution without loss of flavor, vitamins, carbohydrates, etc. The purpose is to provide a functional packaging that can be stored fresh for a long time.

Referring to the configuration of the present invention for achieving the above object in detail as follows.

The present invention is 10% (weight ratio) of 320 mesh jade powder 10% (weight ratio), biotite powder 10% (weight ratio) ), Put 10% (weight ratio) of elvan powder and 60% (weight ratio) of loess powder into a blender, mix 30% (weight ratio) of the mixed stock with water, and then rosin 15% (weight ratio) of the total mixture. And papermaking and drying in a conventional manner in a paper machine to prepare a functional packaging for rice.

In the present invention, the composition ratios of ocher, jade, biotite, and elvan, which are biofunctional materials that radiate far infrared rays in common, are defined as thresholds for optimizing the radiation intensity of far-infrared rays, which is balanced with temperature even at a normal temperature of 25 ° C. This is to maintain the taste and quality of the rice.

The present invention is a composite synergistic effect of various environmentally friendly materials obtained from nature and confirmed the safety of food, maintaining the freshness and antimicrobial effect, deodorizing effect, moisture to tack pulp with high viscosity as a paper stock It is a far-infrared radiation material with excellent removal effect. It is mixed and papered by adding natural minerals such as ocher, jade powder, biotite, and barnstone powder, which are natural growth accelerators, and preserved and durable. It has excellent cushioning properties, and has antibacterial, deodorant, and freshness retention effect due to the release of far-infrared rays, and it is easy to reduce the quality of rice due to deterioration, decay, and pests during distribution without loss of flavor, vitamins, carbohydrates, etc. Regardless of the rainy season or summer season, It is characterized by providing rice-only packaging material suitable for rice that can be kept fresh for a long time without receiving much.

Hanji is the most ideal natural material that maximizes breathability, which automatically adjusts temperature and humidity by adapting to the external environment from a long time ago. The natural doc pulp, the raw material of Hanji, makes the paper firm by the strong fiber of bast fiber, which has beautiful and tough characteristics, and tensile strength. It is strong, has excellent water absorption function, has high viscosity and strong binding, so it absorbs far-infrared radiation materials such as ocher, jade, biotite powder and charcoal, and it is soft and durable when it is made of Hanji. In the present invention, high quality ocher or mineral which is not contaminated by adding rosin which has a property (tensile force) to disperse the fragrance and to strengthen the paper as a sizing as a surface material (sizing) in the paper of the wrapping paper mixed with the support material and the far infrared radiation material Viscous, uniformly and firmly dispersed As the cushion and tension of the sieve become stronger and the surface state becomes sizing, the strength of the front and back surface is increased during papermaking, so that there is no staining, agglomeration, dropping or peeling of ocher, and the Hanji film that is weak to moisture is formed smoothly and hardly. At the same time, it protects rice from rot and oxidation by improving water resistance to selectively block moisture, breathability to pass air or gas, and heat insulation to block hot or cold air, thereby improving shelf life and shelf life.

Ocher, which occupies more than half of the active ingredient according to the present invention, contains a large amount of soil microorganisms and minerals, has a foaming effect without firing, and is a porous structure of natural honeycomb structure that acts as a pore. Because of its strength and breathability, the living body breathes and emits a lot of far-infrared rays, and when far-infrared rays are absorbed by plants, the molecules constituting the living body resonate and resonate to promote thermal energy, and bacteria, such as bacteria, which cause deodorization and decay. It has a sterilizing effect and maintains the freshness of food, etc. as a wetting effect. It is a material that has adsorption and natural degrading power. It maintains a comfortable temperature for all seasons regardless of the external temperature, and it absorbs moisture and sprays it when it dries. Peroxide, an enzyme in soil that provides toxins to organisms Inhibits catalase (oxidase), which provides the proper soil environment for living organisms, diphenol oxidase, which strengthens the oxidative power of soil, and saccharase (glycolytic enzyme), which acts as a fertilizer in rice farming, and decaying bacteria. By the complex activity of the protease (proteinase), which is a kind of fresh crops have a beneficial effect on the rice and loess microbes inhibit the growth and odor of pathogenic microorganisms.

The above-mentioned ocher can be selectively used regardless of the place of origin or type, and the fine particles are fine and clean, and the sediment in the bucket is taken to remove impurities, dried and then pulverized. As it is difficult and dry, it is hard, cracked, and easily decomposed into water, so that the water resistance is reinforced while maximizing the advantages of ocher. It is tightly coupled and integrated.

Jade, which contains a large amount of minerals, calcium, iron, and magnesium, which are beneficial to living organisms, has far-infrared radiation energy beneficial to humans and crops.

Far-infrared radiation from elvan maintains the freshness of rice and increases the taste, and the anion makes the rice alive and breathes, kills pests (rice mold), inhibits bacterial growth, and adsorbs pollutants such as heavy metals. It controls the humidity to prevent decay through deodorization, moisture-proofing and sterilizing effect to maintain the taste and quality of rice.

The biodegradable germanium biotite has antibacterial, antibacterial, antifungal and harmful gas adsorption, releases a large amount of anions and activates water molecules to promote growth.

As described above, the packaging material of the present invention formed by combining natural pulp, Doc pulp, and loess, has excellent air permeability, which maintains freshness in and out of the air by microporous pores (pores) through which air is permeated but water does not. It maintains the optimum water content that influences the taste of rice by the four seasons constant temperature and humidity effect, and enhances cushioning and tensile force to safely preserve the rice's appearance without damaging it, while activating water molecules of rice by resonance absorption caused by far-infrared radiation. The activated water molecule activates dissolved oxygen to inhibit the invasion of decaying bacteria such as bacteria and maintains freshness for a long time, and removes odors by cationizing air in sealed packaging material and promotes metabolic activity by capillary phenomenon of surface tension. Maintaining the taste and quality of the distributed rice for a long time Recent studies have shown that far-infrared treatment increases GABA (γ-aminobutyric acid) by activating GLUTAMIC ACID decarboxylase, such as rice.

Functional packaging material according to the present invention is not only the effect of storing in loess or loess rice poison (jar), etc. by preventing the direct exposure to sunlight and pests, reinforced with a soft texture which is the characteristics of Hanji buffer, warmth, hygroscopicity Because of its strong geology, it is not easily torn in the wind, so it is not necessary to store it in a separate rice dock or rice pail at home.

In addition, the functional packaging material of the present invention is capable of precise printing because the surface is clean and smoothly formed while expressing the natural color tone unique to ocher, and can be formed to have a multilayer structure by laminating by a conventional papermaking method. As it is well decomposed and has a natural self-cleaning power and is a soluble, environmentally friendly material, it is naturally decomposed and reduced to soil after use, and can be disposed of without pollution due to secondary pollution.

In addition, since the rice packaging material of the present invention is uniformly mixed with ocher, finely divided jade powder, biotite powder, and Doc pulp, the far-infrared radiation specific surface area acting on rice is increased, thereby maximizing far-infrared radiation efficiency.
