Description

Natural substance formulation having freshness improvement effect of fresh ginseng and method of improving fresh ginseng storage using the same

The present invention relates to a natural material formulation having an effect of improving the shelf life of agricultural products, especially ginseng, which is a high value-added product, and a manufacturing method thereof. In particular, the natural material formulation is composed of a powder, sheet, pellet and plate form It relates to a formulation and a method for producing the same.

Ginseng is produced more than 90% in Korea and China all over the world, and the main consumers are China, China, Hong Kong, Taiwan, Southeast Asia, etc., and Japan. In Korea, the ginseng of Korean ginseng is widely known and sold at a higher price than Chinese ginseng or Japanese ginseng. One of the obstacles to the expansion of ginseng is the storage form and storage period of ginseng.

Ginseng is largely divided into red ginseng, white ginseng, and ginseng. Red ginseng and white ginseng are processed with steamed or dried ginseng, and ginseng refers to unprocessed ginseng as it is. In the overseas market, red ginseng from China, white ginseng from Chinese dried ginseng and North American ginseng dominate the market, which is a major obstacle to exporting Korean ginseng and ginseng products. In contrast, ginseng is not yet established in the market except in some parts of Korea and Japan. Therefore, it is necessary to promote export of Korean ginseng by developing and exporting fresh ginseng products.

Fresh ginseng has less bitterness and soft taste, so many people prefer it. However, as mentioned above, ginseng is raw ginseng as it is, as it is, in its natural state, and thus contains moisture.

As a method of mass storage of fresh ginseng, cold storage, decompression storage, modified atomosphere (MA) storage, and controlled air (CA) storage have been developed, but ginseng farmers and merchants handling ginseng are mainly cold storage methods. Is using. Even when fresh ginseng is refrigerated at 4 ° C, freshness is only maintained for about 1 month, and the quality is deteriorated due to mold development. Domestic ginseng is still marketed with dirt still on the market, and department stores and some convenience stores cover it with moss and distribute it in small wraps or plastic wraps, but none of these methods are intact. It does not sufficiently extend the lead retention period of.

In China, over 10 years ago, a method was developed to package and sell fresh ginseng individually as a soft film. Such a method is that the fresh ginseng washed with water was packaged in a polyethylene film after being treated with fresh oil, but the fresh ginseng was distributed in a very weak and soft state unlike the fresh ginseng currently distributed in Korea.

On the other hand, there have been methods of dipping fresh ginseng in salt water, alcohol, or honey or fumigation of sulfur, but these are all processed and processed to some extent, and cannot be said to provide fresh ginseng as it is. .

Methods have been attempted to preserve freshness of fresh ginseng by storing it in a polyethylene film and vacuum packaging or in a polypropylene film bag such as casted polypropylene (CPP) or oriented polypropylene (OPP).

However, none of the above conventional methods is capable of maintaining freshness of fresh ginseng in its natural state for a sufficiently long period of time that it is commercially circulating, including export.

It is an object of the present invention to provide a method for maintaining freshness of a fresh ginseng as it is without undergoing any direct chemical change for a longer period of time.

In addition, an object of the present invention is to provide a natural substance formulation that can extend and preserve the freshness of fresh ginseng.

It is an object of the present invention, in particular, to provide a natural substance formulation present on the powder, pellet, plate or sheet of natural substance for improving the shelf life of fresh ginseng.
