The present invention relates to a food wrapping paper coating composition, and more particularly, containing natural mineral powder, to minimize the physiological action of the stored food to minimize the loss of nutrients and moisture, and to have environmentally friendly environmental pollution It relates to a food packaging coating composition that does not cause.

With the full opening of agricultural products, the competitiveness of domestic agricultural products is urgently needed, and the demand for safe and fresh foods (especially fruits and vegetables) increases, so as to maintain the freshness of foods to maximize the freshness of raw materials, pre-processing and processing processes. Attempts have been made to improve the quality of life, such as the improvement of distribution and distribution technology.

The field to which the present invention pertains is one of them. In particular, the related art related to the improvement of the wrapping paper in the distribution process has a coating layer containing loess of Korean Patent Application Publication No. 10-2002-0031860 published in Korean Patent Publication. There is pulp paper for food. In the disclosed invention, there is disclosed a food pulp paper having a coating layer containing ocher, characterized in that the ocher coating layer is processed on one side or both sides of the food pulp paper, wherein the ocher coating layer is ocher, alcohol , Water, and polyvinyl alcohol (PVA).

However, the present invention has a certain degree of moisture-proofing, insect repellent, etc., and has an effect of extending the shelf life, but can be applied only to pulp paper, the extended period is still insufficient, artificial additives as food adhesive Using it can be problematic for its harmfulness to the human body.

The present invention has been made to solve the above problems, an object of the present invention is to provide a food packaging coating composition for maintaining the maximum freshness of food using mineral powder.

Another object of the present invention is to provide a food wrapping paper coating agent consisting of only natural materials, which is completely harmless to the human body and does not cause any problems in the environment when recycling packaging materials.

The present invention is characterized in that it comprises a mineral powder pulverized two or more components selected from the group consisting of tourmaline, earthenware, ganban stone, homer stone, large grain stone, cerium stone.

Tourmaline is a crystal in which magma eluted by a volcanic eruption more than 10,000 years ago is formed at high temperature and high pressure, and its crystal state is hexagonal, and its composition consists of Ca, K, Na, Cr, Fe, Li, Mg, Mn, and Si. It is. Tourmaline is a mineral that permanently emits weak electricity and is known as a tourmaline, and it generates anions and far infrared rays to activate cells, and it is recognized for use as a food additive that is harmless to the human body.

The natural earth is an alkaline mineral mud that is absorbed and stored in the ground by the volcanic eruption. The main constituents are quartz, plagioclase, biotite, kaolin and dolomite, and their specific chemical composition is shown in Table 1.

ingredient SiO ₂ Fe ₂ O ₃ Al ₂ O ₃ CaO MgO Na ₂ O K ₂ O Earthenware (wt%) 67.2 3.03 18.8 1.34 2.27 2.72 4.11

Cheonggi earthenum evenly contains various rare earths as well as pain-reducing ingredients and natural geomagnetic components, and is used as a herbal medicine because it has good affinity with the human body and shows excellent efficacy in anticancer effects. Tourmaline also neutralizes negative ions and electromagnetic waves, called vitamins in the air, and produces far-infrared rays that activate cells.

Elvanite belongs to feldspar rock among igneous rocks. It is a gemstone produced by mixing feldspar and quartz crystals by eruption and intrusion from the late mesozoic to the early stage. Heo Joon's consent is a natural stone that was used as a weak stone because it is sensational, warm and nontoxic, and it is effective in treating skin diseases and trauma.It contains more than 45 kinds of mineral elements and adjusts the pH of various minerals and increases dissolved oxygen. Not only is it effective in improving water quality, it also radiates more than 90% of high-efficiency far-infrared rays to promote biological growth and vitalize the human body.

In addition, elvan has the excellent antimicrobial activity against general bacteria and Escherichia coli, etc. due to its porous characteristics, it has the effect of adsorbing ethylene gas generated from the breathing of agricultural products (fruit vegetables), etc. to extend the shelf life and excellent adsorption of various harmful substances. . In addition, elvan has an excellent effect on the action of heavy metal decomposition, mineral elution, water quality control, anion spinning.

Elvan has a slightly different chemical composition depending on the type, but the composition of the powdered product is generally shown in Table 2.

ingredient SiO ₂ Fe ₂ O ₃ Al ₂ O ₃ CaO MgO Na ₂ O K ₂ O Elvanite (wt%) 65.48 2.89 15.68 4.00 1.74 5.12 1.66

In addition, ores such as cerium ore, precious stones, and daegak are also ores having the characteristics of emitting negative ions and far infrared rays, and are characterized by ionizing air by radiation energy emitted from the ore itself.

When the anion is sufficiently supplied, the ionization amount of sodium and calcium is changed to an alkaline constitution, thereby reducing headaches, muscle pain, fatigue, and finding a refreshing condition. There are effects such as antibacterial, deodorization, immunity, and cell activation.

As described, the minerals used in the mineral powder constituting the food packaging composition according to the present invention have a common feature composed of porous ores having the characteristics of emitting anions and far infrared rays.

At this time, the composition of the porous ore is to adsorb ethylene gas because the ethylene gas is more accelerated the physiological action of the food when ethylene gas is generated as the storage period of the stored food elapses to promote the decay, the anion is emitted The use of minerals is because when negative ions are supplied to foods, they play a role in neutralizing oxygen generated by food's physiological action to reduce the decay rate.

On the other hand, each mineral ore has a different amount and the amount of anion and far-infrared radiation, and has a beneficial effect depending on the food, so if you use only a lot of anions with excessive anions come out or economical This fall occurs, and it is necessary to adjust the mineral content appropriately for use in all foods.

In other words, the preferred amount of anion radiation of food wrapping paper is 250-750 / cc, and the use of ganban ore among mineral ores is used to solve the above problems. I can keep it.

Adhesives are needed to crush mineral ores and coat them on food packaging. The adhesive is a natural product, which is used as an adhesive material in which sodium alginate, isolated soybean protein, and starch are used alone or mixed with each other. Sodium alginate is a material used for making impressions in dentistry and is harmless to the human body. The isolated soy protein is a by-product of soybean cooking oil, and starch is a processed food raw material.

The adhesive material is preferably used by dissolving in water so as to be 5 wt% to 20 wt% based on the weight of the adhesive.

A preferred embodiment of the food packaging coating composition according to the present invention is as follows. However, it is obvious to those skilled in the art to change the weight ratio of the mineral powder, change the applied food, or change the wrapping paper presented in the examples of the present specification and will not depart from the scope of the present invention.

Experimental Example

The coating composition prepared as in Examples 1 to 3 () was coated on a cardboard box (a box of 270 × 110 × 100 mm size) using an adhesive, and then the leaf lettuce was put in weight loss, moisture content, and vitamin C. (Ascorbic acid), chromaticity, and overall visual quality (OVQ) were measured. For the experiment, leaf lettuce was washed in 40 ppm of chlorine sterilized water for 3 minutes, excess water on the surface was wiped with a tissue before being boxed, and stored for 8 days at 5 ℃ and 25 ℃. On the other hand, leaf lettuce packaged in a box that was not treated as a control (control).

All records were recorded daily so that the nature of the fresh leaf lettuce changed over time.

1 is a graph showing the change in weight of leaf lettuce over time. According to this, although the weights of both the Examples and Comparative Examples decreased over time, the Examples show that the weight of the leaf lettuce less than the Comparative Examples.

Figure 2 is a graph showing the change in water content of leaf lettuce over time. Moisture content was carried out by the method of American Organization for Analytical Chemistry (AOAC), the examples also show that the change in moisture content is significantly less than the comparative example, especially Example 2 is 6 days at 25 ℃ It retains an amazing 85% moisture level even after elapses.

3 is a graph showing the change in ascorbic acid of leaf lettuce over time. At this time, the content of ascorbic acid was measured by reflection measurement using the DNP method (ditrophenyl method). Changes in the content of ascorbic acid also show excellent effects compared to the comparative examples in the same manner as in FIGS. 1 and 2.

4a, b and c are graphs showing the change in chromaticity of the leaf lettuce over time (Fig. 4a is a *, Fig. 4b is b *, and Fig. 4c shows L *, respectively). The surface color of the leaf cabbages was measured using a Minolta chromatograph CR-200 colorimeter with the L * a * b * system of CIR. The a * value measures the degree of red (+ a *) or green (-a *), b * measures the degree of yellow (+ b *) or blue (-b *), and L measures the degree of brightness. Measure In particular, it can be seen that the a * value of the comparative example of 6 days at 25 ℃, significantly higher than the experimental examples.

5a and b are graphs showing the change in sensory quality of leaf lettuce over time (FIG. 5a is the overall sensory quality and 5b is the degree of yellowing). In FIG. 5A, values from 1 to 6 are used, where 6 is good, 4 is good, 2 is insufficient, 0 is low, and a value of 3 is a minimum value required to secure marketability. In FIG. 5B, 6 is all, 4 is severe, 2 is slightly, and 0 is no. In the experiments in Figures 5a, b it can be seen that the examples show excellent measurements compared to the comparative example.

On the other hand, looking at the effects of the embodiments, it can be seen that Example 2 has a remarkable effect compared to other examples, which indicates that it is more advantageous than the case of high elvan in the mineral component. Therefore, it is essential to include elvan in the mineral powder and the weight percent of elvan in the mineral powder is greater than the sum of the remaining components in the mineral powder.

Next, the manufacturing method of the coating composition which concerns on this invention is demonstrated.

Grind one or two or more components selected from the group consisting of tourmaline, earthenware, elvan, elvan, barley, large grains, and cerium to form a mineral powder with a particle size of 500-3000 mesh. . If the particle size is less than 500 mesh, it is difficult to coat, the adhesion is poor, and if more than 3000 mesh is less than that because it is not economical because there is no difference.

Meanwhile, sodium alginate, isolated soybean protein, and starch, which are rich in minerals and have adhesion as a natural substance, are dissolved in water so as to be 5% to 20% by weight of the adhesive alone or mixed with each other. Prepare the adhesive. This is because when the adhesive material is too small, the adhesive strength decreases, and when the adhesive material is too large, the viscosity becomes too strong to be disadvantageous in coating.

Next, when the weight ratio of the mineral powder in the total weight of the coating composition is 3% by weight to 30% by weight, and the weight ratio of the adhesive is 70% by weight to 97% by weight, the composition is completed. If it is less than 3% by weight, it is difficult to expect the effect of the release of mineral powder, such as far-infrared rays, and if it is more than 30% by weight, the adhesive strength is reduced.

The prepared coating composition may be coated on the package by conventional methods, that is, roll coating, dipping or spraying.

Although the present invention has been described primarily with reference to the above embodiments, many other possible modifications and variations can be made without departing from the spirit and scope of the invention. For example, changes in composition ratios that do not produce significant effects, addition of similar minerals, and the like will be changes that can be readily derived by those skilled in the art.

Effects on the food packaging coating composition according to the present invention made as described above are as follows. First, the food packaged with the food packaging paper coated with the composition according to the present invention is improved freshness by the action of anion emission, far-infrared emission, adsorption of harmful substances, insect repellent, deodorization, weight, moisture, Vitamin C, color, etc. are kept constant. Second, by using only 100% natural materials as a coating composition does not adversely affect the human body, unlike artificial chemicals at all, there is no problem when recycling, it can be applied to all papers, synthetic resins, etc. without limiting the type of packaging.

The scope of the above-described invention is defined in the following claims, and is not bound by the description in the text of the specification, all modifications and variations belonging to the equivalent scope of the claims will fall within the scope of the present invention.
