"E-jen" Vacuum and Airtight Storage Container

Principle of "e-jen"

All the containers as we know are composed of bodies and lids. All of them have air layer with the same size of the contents (layer between lids and contents, HEAD SPACE) and the more we pull contents out of containers, the bigger head space and this makes molds or deteriorate the original taste of food by bad microbes in the air. E-jen, vacuum and airtight storage container, has vacuum plate (pressing plate) in the middle of the container and movable upward and downward. If you press the plate close to the food inside, the air in the container becomes minimized and blocks air flowing from the head space so it has very similar effect to cans.

There are many fermented food in Korea such as kimchi, soy bean sauce and pickle. To store these foods, people have used kimchi leaves to cover the upper part or wide and heavy stones for pickles not to float.

The vacuum jar called e-jen has silicon packing inserted along the edge of the vacuum plate. The pressing mechanism of the vacuum plate improves the insulation of the silicon packing and has the following features.

1. Preserving perishable food in a container
   
2. Compacting food
   
3. Preserving perishable food in a vacuum state
   

The e-jen is a preservative container with the same benefits of canned food in the utility sense of being a container, compactor and preserving the contents in a vacuum state.

Effects for Use

1. The "e-jen" is a storage science based on the rule of zero-stale smell, zero-mold, zero-top layer and zero-air.

2. The "e-jen" is not allowing air in to keep the food fresh for a long time.
The inner lid of the "e-jen" extracts all air from the space under the inner lid to prevent the mold, an aerobic microorganism living in the presence of air, from being reproduced on the surface of the soybean paste (Doenjang) and the hot pepper paste (Gochujang). No stale smell or a top layer is found in Kimchi and pickles stored in the "e-jen". Based on the same principle of the canned goods that are preserved in vacuum, the "e-jen" is able to maintain the vacuum inside continuously during the storage.

3. The "e-jen" keeps a unique taste of the food twofold.
Enjoy the taste of the carbonated water of Kimchi and Watery Radish Kimchi, which cannot be expected from those stored in a common container.

4. The "e-jen" keeps the flavor of food from the beginning to the end of the storage.
The "e-jen" extracts all air from inside to prevent the food from being over-fermented, turning sour, and browning.
