E-JEN
Vacuum and Airtight Storage Container
Principle of e-jen
To store foods for a long time, we have to protect them from being perished and there are four factors playing a role in perishing such as
1) temperature 2) moisture 3) nutritive elements and 4) air
If one of these factors is insufficient or doesn\'t exist, the putrefaction never happens or goes slowly.
One of the best ways to store food is containers like canned goods or cans.
The canned goods are available to store foods for a long time for storing foods in vacuum state but they can be used just one time.
If there is a container providing vacuum function like cans and is able to use several times, it will be an outstanding one.
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.
At the edge of vacumm plate of e-jen, silicon packing is inserted and if you press the plate the packing makes it fixed so it can provide three functions at the same time including covering foods, pressing them with stones and generating vacuum state.

Effects for Use In the middle of the vacuum and airtight storage container, there is vacuum plate (pressing plate) movable upward and downward. You can store food with vacuum state by pressing the plate to move it close to the food and there are effects as follows
1. Kimchi
The vacuum plate makes kimchi inside the kimchi juice so it can keep its vivid colors and is crisp for making kimchi tissues alive and you can taste carbonated like sodas because the carbonate from fermentation of kimchi dissolves in the juice.
The pressing plate blocks the air outside and makes kimchi anaerobic state and you can have kimchi with many lactobacilli by helping proliferate them.

2. Soy Sauce
Many kinds of fungi, aerobic microbes, on the surface of soy sauce. If the pressing plate is close to soy Sauce,
the surface of sauce doesn\'t contact air
and you can have healthy sauce without microbes.
3. Pickles
Pickles are stored in salt water and the surface of
the water, aerobic yeast fungi are proliferated and
make the surface white and if the pickles float on the
water, the tissue gets soft so we can\'t eat them.
The vacuum plate in the e-jen keeps pickles inside
the water so it makes tissues firm and prevents
generation of the yeast fungi by blocking contact with air.
4. Fruit Wines (Enzymes for Fermenting Vegetables and Fruits)
Fruit wines are made by yeasts, alcohol
fermentation fungi inside wines and there
should be joy of smelling alcohol and fruits if the
unique smell of fruits remains inside the
alcohol. It is important to minimize contact with
air in making fruit wines.
If air remains inside the wines,
1) Alcohol becomes oxide by acetobacters which like oxygen in the air and people can\'t unique smell of fruit wines due to smell of vinegar in fruit wines from acetic acid fermentation.
2) Fruits on the surface are exposed to air and generate fungi, aerobic microbes. They produce abnormal fermentation, curb yeast generation, alcohol fermentation fungi, and generate foreign materials.

If you store fruit wines in e-jen, vacuum and airtight storage container, 1) you can prevent acetic acid fermentation because the vacuum plate blocks outside air and makes inside vacuum state
2) production of foreign materials are blocked by preventing abnormal fermentation
3) this helps normal fermentation by promoting generation of yeasts, anaerobic alcohol fermentation fungi and
4) you can feel taste and smell of taste at the same time.

5. Advantages in Storing Other Foods
1) Aging effect for taste:
1) Aging effect for taste:
marinated ribs, ingredients in pig intestines. In the aging process or storing meat in the refrigerator, you can store it for a long time and have tasty meat.
2) Blocking humidity:
2) Blocking humidity:
Green tea leaves, snacks, bread crumb, seaweed, cereals.
Green tea leaves, seaweeds and snacks tend to get soft by humidity in the air and the container protects them by minimizing air
3) Curbing growth: mushrooms
If mushrooms are exposed to air, they start to grow and taste and quality get deteriorated so the growth will be curbed by keeping vacuum state
4) Blocking evaporation: dried goods including anchovies
If fishery goods such as anchovies become dried too much, they will become hard and easily break
5) Vacuum effect: tofu, chopped garlic, fruits, salad, left canned foods
If these kinds of food are exposed to air, they lose their colors or go bad. The container keeps them in vacuum state and is possible to preserve the taste.
6) Blocking to become soft: fruits, salads, vegetables
They don\'t become soft or fade by blocking contact with air and keeping humidity
7) Blocking bugs: grains including rice
Curbing bugs in storing grains such as rice
8) Keeping freshness: vegetable juice, fresh juice
One or two hours after making vegetable or fresh juice, they lose colors and taste. If you put them into e-jen and store in the refrigerator, you can store them more than a week with fresh taste.
