Description

Blockchain-based Kim history management method and history management system using it {A METHOD OF MANAGING THE HISTORY OF LAVER BASED ON A BLOCK CHAIN AND A HISTORY MANAGEMENT SYSTEM USING THE SAME}

The present invention relates to a block chain-based Kim history management method and a history management system using the same. More specifically, to provide a method and system to manage and track the history of laver including the origin and producer information of the dried laver or seasoned laver produced, which can occur while increasing the shelf life of dried laver or seasoned laver. It is to provide a block chain-based steam history management method and a history management system using the same to verify the origin and producer.

As life's prosperity and basic satisfaction of food, clothing, and shelter are realized, the shape of life is changing significantly. For example, agricultural products can be consumed at any time, and the range of agricultural products consumed is becoming more diverse due to the expansion of the distribution network and the development of technology.

As consumption of such diversified agricultural products becomes possible, there is a need for measures to increase the safety of the agricultural products consumed and the reliability of the origin and producers.

In other words, since agricultural products produced by technological advances are sold through international distribution networks as well as across the country outside of their production area, it is becoming difficult to trace the distribution channel in reverse to find out the cause when a problem occurs in distributed agricultural products. . In addition, in the case of products whose demand and price varies depending on the place of origin or producer, it is important to be able to discriminate false information about the place of origin or producer.

Currently, there is a problem that the history management of agricultural products is roughly made in books or in the fact that the contents of producer and country of origin information indicated in the production area have to be trusted and traded. Accordingly, in the conventional technology presented accordingly, identification information such as a specific barcode is marked so that the identification information is input for each distribution route.

However, the first problem is that the above identification information is managed by each local government, and each local government uses different types of identification information with different standards.

The second problem is that identification information such as barcodes is easy to forge, so if the identification information is forged, it is difficult to verify it, and it is difficult to effectively cope with illegal use by falsely indicating the origin or producer information of agricultural products. .

As a third problem, when a problem occurs in a specific agricultural product, it is difficult to specifically recover the agricultural product that may have the same problem through the same origin or producer or distribution channel. That is, since the identification information contains only general origin or producer information, there is a limitation in that it is difficult to specify and process agricultural products in which problems occur by classifying them by system of specific products.

The fourth problem is that the amount of information stored is limited. The above identification information has a limitation in that it is not possible to provide history information about the product with more diverse information, since only brief information such as the place of origin and the first producer is marked, reproduced, and attached.

The fifth problem is that it is difficult to trace each distribution channel in reverse. In particular, although some traceability may be possible until the wholesale stage, it has a limitation that it becomes virtually impossible to trace the distribution history of the product when the product enters the retail stage. Therefore, when a problem occurs in a product purchased by a consumer, it is difficult to determine the situation in which the product in question is distributed by tracking the distribution channel in reverse.

Finally, it has a problem that it is difficult to help simplify the complex distribution channels of agricultural products. If information on specific products is included and provided to consumers along with information on product history and distribution channels, consumers can have a wider range of choices, thereby reducing unnecessary distribution channels for products and ultimately price competitiveness for agricultural products. It is possible to increase its consumption by increasing the value. However, the conventional technology cannot handle this role.

Specifically, looking at the prior art, Korean Patent Application Publication No. 10-2006-0055196 (published on May 23, 2016) manages production history including nurturing, acquisition, processing, packaging, etc. of agricultural and livestock products. It discloses a method and system for managing the history of agricultural and livestock products that can guarantee the quality of agricultural and livestock products by making it possible to check the production history of water.

However, the invention disclosed in Korean Laid-Open Patent Publication No. 10-2006-0055196 (published on May 23, 2016) allows consumers to check the history information of livestock products, and may occur during slaughter, processing and distribution. There is a problem that it cannot prevent problems such as false labeling of the country of origin and the sale of dungap.

In addition, there is a problem in that the consumer must directly check the history information of livestock products, and the manager who manages the distribution of livestock products has to invest manpower and time for the overall management of the slaughter, processing and distribution process, which increases the management cost. Can occur.

As another prior art, Korean Laid-Open Patent Publication No. 10-2007-0047005 (published on May 4, 2007) is identified by a system design and operator to an arbitrary farm (here farming means encompassing agricultural, livestock producers). Generating and registering a possible farmhouse unique code and registering additional farmhouse information; Creating a database of farmhouse information related to the production of the farmhouse code and agricultural products (agricultural products here means encompassing agricultural, livestock and livestock products) by a system design and operator; A step of requesting a search after a consumer or the like inputs a farmhouse code generated by the system design and operator using a personal information communication device or a computer; Providing farmhouse information in a database corresponding to the input farmhouse code from a web server to a personal PC or portable information communication device through wired and wireless Internet; And it proposes a farmhouse history system based on farmhouse code and a method of operation thereof, including the step of creating and preserving a farmhouse information list for purchase by a consumer registered in the farmhouse history system.

However, the above prior art also remains in information that can confirm producer information by simply searching the farmer, which is the producer, using the farmhouse code, and thus the problem presented above is not solved.

On the other hand, the inventors analyzed the distribution channels for dried laver and seasoned laver among agricultural products. In the case of laver, the producer is important along with the place of origin. However, when looking at the current route of laver distribution, it was confirmed that the local wholesaler actually proves the place of origin, and the first producer is not accurately known as laver purchased from the wholesaler is mixed.

The present inventor proposes a method to increase the distribution period of laver, and includes production information and distribution information on laver sold in anticipation of the occurrence of more diverse distribution channels through complex retail channels as the distribution period of laver increases. It has been completed by researching a blockchain-based Kim history management method and a history management system using the same that enables history information to be more clearly identified and to have reliability.

Accordingly, the present invention provides a gas replacement packaging for long-term storage of laver used as a gas mixture in a packaging material by using an optimal gas mixture capable of preventing a long-term state change of dried laver or seasoned laver during gas substitution packaging.

The gas replacement packaging for long-term storage of laver is to replace the air in the packaging material with a gas mixture to prevent a change in the state of laver, and the gas mixture includes carbon dioxide, argon, and nitrogen.

The gas mixture may include 10 to 30% by volume of carbon dioxide, 1 to 5% by volume of argon, and the remaining nitrogen.

Lavers is Porpyra seriata belonging to the red algae family, and its vitamin A content is 14,000 IU, which is 1400 times that of beef, 70 times that of pork, and 3.5 times that of carrots. Accordingly, the value of Kim is also being highlighted. Its calcium content is 390 mg, which is 100 times that of beef, 80 times that of pork, and 4 times that of milk. In addition, the content of EPA (Eisasa Pentaenoic Acid), a polyunsaturated fatty acid, accounts for more than 54.1% of the total fat, and various physiological functions of laver, such as promoting the production of PGI ₃ to prevent blood clots, are the modern people who pursue a healthy life It is a food material that meets the needs of

Processed laver includes grilled laver and seasoned laver. Due to the development of laver processing technology and packaging, the recommended shelf life of seasoned laver is 6 months, but the acid value (Acid Value) of 4.0 and the peroxidase value (Peroxidase Value) of 60.0 or less.

In particular, seasoned laver is produced and consumed throughout the year, so there is a great concern about quality degradation during storage and distribution.

The main cause of this deterioration is lipid oxidation, and moreover, seasoned laver is heated at a high temperature of 200°C or higher for several seconds by applying about 10 to 50% of edible oil, so that oxidation is further promoted due to various chemical reactions.

These oxidized compounds of unsaturated fatty acids can be more harmful than ingestion of animal saturated fatty acids and are of interest because they are related to the expression of arteriosclerosis, liver damage, and proliferation of intestinal tumors.

Vegetable oils such as jade oil, sesame oil, and perilla oil used for seasoned laver are rich in highly unsaturated fatty acids such as linolenic acid, which is an essential fatty acid, and are excellent in nutritional value, but they are easy to oxidize by oxygen and heating. It contains more than 50% of unsaturated fatty acids and 400 to 700 mg of chlorophyll, which can act as an oxidation promoter, so it acts as a major factor in promoting lipid oxidation.

The general seasoned laver manufacturing method is a process of applying a single or a mixture of two or more vegetable oils such as soybean oil, sesame oil, and perilla oil to the raw laver, and then passing through the laver tunnel (200 to 400℃) while sprinkled with salt. Will go through.

The passed seasoned laver is packaged with a desiccant (silica gel) to maintain the crispy texture of the laver in the form of 9, 6, or full length depending on the purpose. The content (% by weight) and type of vegetable oil used in seasoned laver varies by manufacturer, but it is usually in the range of 10 to 50%.In recent years, olive oil and brown rice oil, which emphasize functionality, are added to match the well-being trend that pursues health. High-end products with increased oil content are appearing one after another to emphasize sensuality.

However, due to the product characteristics of seasoned laver, which contains a large amount of oil and vegetable oil with a lot of unsaturated fatty acids, it cannot be free from rancidity of fats and oils, which is the biggest factor in the shelf life restrictions of seasoned laver. In fact, in the case of oil-treated laver in the food industry, the peroxide value and acid value, which are measures of oil and rancidity, are regulated to be less than 60 and less than 4, respectively.

In order to delay the rancidity of oil and fat, it is possible to consider adding antioxidants, but the selection of antioxidants that are stable even at high temperatures (200 to 400°C) in the tunnel passing through for roasting and the cost increase due to the expensive antioxidant unit price is very narrow. There is a difficulty in applying the agent to seasoned laver.

In order to delay the rancidity of fats and oils as described above, a number of technologies have been developed for the manufacturing method of functional seasoned laver, but generally only relates to the use of various natural powders in the manufacture of seasoned laver. Technology for delaying rancidity is not actually being developed.

Currently, many seasoned seaweeds that are generally sold do not contain natural powders to delay rancidity of oils and fats as described above, and considering this situation, many seasoned seaweeds on sale have a short shelf life of about 6 months. Only is being provided.

In addition, roasted laver and dried laver among processed laver, unlike seasoned laver, do not cause rancidity of fats and oils, but as laver itself absorbs moisture in the air, the state of laver changes, making it difficult to consume. .

In order to prevent this problem, many homes wrap roasted laver and dried laver with newspaper, etc., and store them in a freezer for a long time.

This storage method is a method that can be used for long-term storage in the home where laver is purchased, but manufacturers and distributors who sell laver may experience changes in condition due to the storage environment of laver. There is a problem that laver cannot be sold and all must be disposed of.

In order to prevent this problem, the present invention is to provide a gas replacement packaging for long-term storage of laver.

In particular, in the case of seasoned laver, gas replacement packaging and packaging materials are provided to minimize the use of silica gel for moisture-proofing, thereby preventing a change in state for a long time and minimizing the use of a desiccant.

More specifically, the present invention is to replace the air in the packaging material with a gas mixture in order to prevent a change in the state of the laver, and the gas mixture includes carbon dioxide, argon and nitrogen.

The general composition of air is composed of nitrogen, oxygen, argon, carbon dioxide, water vapor, and the like, and many are composed of nitrogen.

However, it would be said that it is a problem because the state of steam may change due to water vapor, that is, moisture contained in the air.

Therefore, in order to store laver, it is necessary to prevent moisture from being blocked as much as possible to prevent it from getting wet.

Accordingly, in the present invention, a gas mixture is composed of carbon dioxide, argon, and nitrogen to prevent a change in the state of steam due to the gas mixture.

The carbon dioxide (CO ₂ ) is a colorless, odorless, tasteless gas, and can prolong the shelf life of laver by inhibiting the growth and oxidation of aerobic bacteria and fungi.

Argon (Ar) is colorless, odorless, and tasteless. Argon exhibits properties similar to nitrogen and, unlike vegetables, which are generally used in gas replacement packaging, is used as an optimal gas to prevent changes in the state of laver, and when included in a small amount, the effect of extending the shelf life of laver is excellent.

Nitrogen (N ₂ ) is used to replace oxygen by replacing the air inside food packaging with nitrogen. Nitrogen can prevent oxidation of fats and oils and inhibit the growth of aerobic microorganisms.

The gas mixture contains 10 to 30% by volume of carbon dioxide, 1 to 5% by volume of argon, and the remaining nitrogen, and when containing less than 10% by volume of carbon dioxide, there is a problem that the growth and oxidation inhibitory effect of aerobic bacteria and fungi is insufficient. When it exceeds the volume %, a problem of feeling sour in seaweed may occur due to the inclusion of an excessive amount of carbon dioxide.

In addition, when argon is included in an amount of less than 1% by volume, the effect of preventing changes in the state of laver is insufficient, and when it is included in an amount exceeding 5% by volume, there is a problem that economical efficiency is poor.

The packaging material includes a substrate layer, a packaging layer, and a surface layer, and is laminated in the order of a substrate layer, a packaging layer, and a surface layer, and the substrate layer is adjacent to the inner laver, and the surface layer may be exposed to the outside.

A packaging layer is included between the base layer and the surface layer, and the packaging layer is configured to enable printing such as a product name.

That is, the packaging material of the present invention may be manufactured by coating or laminating a surface layer on one side of the packaging layer and then coating or laminating a base layer on the other surface of the packaging layer.

The surface layer may use a method of laminating a polymer film or coating it with a film using a coating composition.

In the case of the polymer film, it may be a polyamide film, that is, a nylon film. Polyamide films, such as nylon films, have excellent oxygen barrier properties, and can suppress the mixing of external air into the mixed gas.

The polymer film may provide excellent airtightness by using a copolymer containing a polyether-based segment in a specific content that imparts elastomeric properties to the polyamide-based resin.

The polyamide resin is a polyamide resin, for example nylon 6, nylon 66, nylon 46, nylon 11, nylon 12, nylon 610, nylon 612, a copolymer of nylon 6/66, nylon 6/66/610 Copolymer, nylon MXD6, nylon 6T, nylon 6/6T copolymer, nylon 66/PP copolymer and nylon 66/PPS copolymer; Or N- alkoxyalkylated products thereof, for example, 6-nylon meximethylated, 6-610-nylon meximethylated or 612-nylon meximethylated, but preferably nylon 6 or nylon 66, nylon 46, nylon 11, nylon 12, nylon 610 or nylon 612.

The polyether segment is selected from the group consisting of polybutylene terephthalate, poly(alkylene oxide) glycol, and mixtures thereof, preferably polybutylene terephthalate.

The content of the polyether segment of the copolymer is 2% to 15% by weight based on the total weight of the base film layer. If the content of the polyether-based segment is less than 2% by weight of the total base film layer, a problem of lowering the moldability may occur, and if it exceeds 15% by weight, the problem of lowering the gas barrier of the polymer film. Can occur.

As described above, since the airtightness of the surface layer is excellent, it is possible to prevent a change in the laver state due to external moisture by preventing the outside air from flowing into the inside during the distribution process of laver.

The base layer may be selected from the group consisting of polyamide, polyethylene phthalate, ethylene vinyl alcohol, and mixtures thereof.

A gas replacement packaging method for long-term storage of laver according to another embodiment of the present invention includes the steps of: 1) putting the molded laver into a packaging material; 2) injecting a gas mixture into the packaging material containing steam; And 3) sealing the packaging material after injecting the gas mixture, wherein the gas mixture may include carbon dioxide, argon, and nitrogen.

Dry laver, grilled laver or seasoned laver is molded, and the molded laver is placed in the packaging material described above.

The packaging material is provided in a state where one side is opened and all other sides are bonded, and the base layer is polyamide, and the packaging layer is a mixture of nylon 66 as a polyamide resin, and polybutylene terephthalate as a polyether segment. A polymer film was laminated and used.

Thereafter, the air in the packaging material was replaced with a gas mixture and injected using a known gas displacement packaging machine. Then, one side of the packaging material was sealed.

The block chain-based steam history management system according to another embodiment of the present invention may be one that performs the block chain-based steam history management method.

In the laver packaging material according to another embodiment of the present invention, in the block chain-based laver history management method, the unique identification number may be printed.
