In particular, it is characterized in that the shelf life is extended by utilizing the powder derived from fish and shellfish, or it is applied to the bottom of the container to function as an antibacterial agent.

According to the present invention, it is possible to easily produce an antimicrobial composition capable of maintaining the freshness of a food by using an alkaline powder produced through the production of an alkali powder through fish and shellfish such as cockles, and an antibacterial plastic material containing the antimicrobial composition.

In particular, it is an object of the present invention to provide a method for improving the antimicrobial function by extending the shelf life by using the powder derived from fish and shellfish or by applying it to the bottom of the container to function as an antimicrobial agent or by using calcium powder derived from fish and shellfish in the production of synthetic resin do.

Preferred embodiments of the antimicrobial composition comprising the fish powder derived from fish and shellfish according to the present invention and the antimicrobial plastic material containing the same are described with reference to the accompanying drawings. In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, the definitions of these terms should be described based on the contents throughout this specification.

First, the present invention produces calcium powder through seafood such as barley. Such calcium powder has an alkaline property and is particularly excellent in antibacterial function for maintaining the freshness of food. It is particularly noted that the calcium powder may be used as a nanoparticle unit.

The antimicrobial composition can be prepared by pulverizing talc and natural wood and pulverizing them and mixing them with calcium powder. The calcium powder is added in an amount of 5 to 6% by weight to polyethylene (PE), 8 to 10% by weight to polystyrene (PS), 8 to 10% by weight to acrylonitrile butadiene styrene (ABS) (PET), 5 to 7% by weight to phenol resin, 5 to 6% by weight to fibrin (PVC) and 4 to 6% by weight to melamine resin to form a new synthetic resin material through master batching .

Such a composition may be a synthetic resin having a maintenance and antimicrobial activity and may be extended to extend the shelf life by using the powder derived from fish and shellfish or may be applied to the bottom of the container to function as an antimicrobial agent or calcium powder derived from fish or shellfish The antibacterial function can be improved.

The powder is mixed with a thermoplastic resin to prepare dishes or containers. That is, an edible pigment of a desired color is mixed with the resin, talc, and nacreous, and the mixture is molded in a molding machine at 200 to 250 ° C to produce a container. At this time, the talc is mixed with 2% of natural sap, 2% of natural sap, 2% of calcium powder derived from fish and shellfish, 2% of edible pigment and 92% of resin.

Herein, the nacre is effective to maintain the freshness of the stored food. In this embodiment, the nacreous nacre is mined from 350 to 450 mesh particles and used. This is because in the past, when the powder having a particle size of 100 to 350 mesh has a large particle size, when it is mixed with the thermoplastic resin, the bonding force between the jade particles and the resin raw material is low and cracks are easily generated at the interface between the jade and resin. will be. Of course, above 450 mesh, the physical properties are better, but in the process of grinding, the expensive grinding machine is needed, so the cost increases. And the total weight ratio of jade is 2%, which is because it is impossible to control the color of the container at the time of 5% or more and the binding force of the jade and resin is remarkably reduced. Also, when jade is mixed at a weight ratio of 1% or less, the effect of maintaining freshness by jade is weak and meaningless.

Next, the calcium powder derived from fish and shellfish (alkaline powder) is preferably pulverized from 350 to 450 mesh, and the composition ratio thereof is suitably 1 to 5%. When the calcium powder derived from fish and shellfish is increased to 5% or more, the lime ingredient of fish and shellfish is melted into food, the strength of container is remarkably lowered, and the inherent color of kimchi may be changed into color of container. It can be seen that the inherent odor adsorption power is remarkably reduced at less than 1%. Calcium powder derived from fish and shellfish can prevent the kimchi from ripening in the container by the lime component, which is one of its ingredients, so that the original taste of kimchi can be preserved and freshness can be maintained.

Talc is used to maximize the effect of the pigment and is applied at a weight ratio of 2%. Pigment is added at a weight ratio of 1 to 5% in order to minimize the background color according to the inherent color of the jade. The pigments used are inorganic and organic dyestuffs. Organic dyes are vegetable and harmless to the human body. Which is harmless to the human body and is non-toxic. This pigment makes it possible to have a visual impression of jade in a manufactured product by selecting a color that can feel the texture and color inherent in the natural wood.

As the resin to be used, a thermoplastic resin is preferable, and a polypropylene resin can be mainly used. At this time, the resin used is harmless to the human body. Examples of the thermoplastic resin include polyethylene, polystyrene, and ABS.

The resin having the above-mentioned components is prepared. First, the jute is mined by a pulverizer to make the particles have a size of about 450 mesh. Next, the talc powder is mixed with edible pigment to prepare a mixture. Calcium powder derived from fish and shellfish and jade powder are added to the mixture, stirred, and stored at a constant temperature for a certain period of time. The powder stored for a certain period of time is mixed with a thermoplastic resin material, melted in an extruder at 200 to 250 ° C, and extruded into a pellet form to remove moisture of the material. The hot air is dried at a temperature of 60 to 80 ° C, A desired shape is produced by using an extrusion molding machine.

The present invention as described above can maximize the strength of the resin by mixing fine particles of resin (PP, PE, PS, ABS, etc.) with talc, natural wood, and calcium powder derived from fish and shellfish, Since the pigment can be mixed, various colors can be changed.

Since the talc and the natural candle and the calcium powder derived from the fish and shellfish are contained in the present invention, it is possible to prevent the foods contained in the tableware from being damaged by the far-infrared rays radiated from the talc and the natural wood, and to prevent the odor generated in the foodstuffs, It is.

On the other hand, when the kimchi is put into the container by the lime ingredient contained in the calcium powder derived from seafood, the acid content contained in the kimchi is converted into alkali, thereby preventing the kimchi from being ripened, .

In the present invention as described above, the composition ratio and the manufacturing method of each material can be easily changed by those skilled in the art within the scope of the right described in the claims.
