Any food gold has a shelf life, of course, coffee beans are no exception. Freshly roasted bagged coffee beans can be preserved for about a month, and coffee beans stored in vacuum can be preserved for about two months. therefore, the editor suggests that if you are a daily coffee drinker, you can buy half a pound first, grind coffee powder at room temperature for a week, and seal it for two weeks. With all that has been said above, what kind of container should we use for preservation?

The one-way exhaust valve bag is the most suitable container for storing coffee. Coffee beans or coffee powder that should be put directly into the one-way exhaust valve bag should be stored in a low temperature and humidity environment and avoid exposure to the sun. It is recommended to finish drinking as soon as possible.

The impact of improper storage

Guangzhou is a hot and humid climate, coffee is easy to produce ochratoxin due to improper environmental temperature and humidity, which is a colorless crystal compound, which has a very serious negative impact on human health, which can lead to kidney poisoning, liver poisoning and even kidney failure or cancer. Coffee beans baked at high temperatures still have 30% residue after five minutes, but also because large amounts of ochratoxin can be produced in roasted coffee beans, regardless of whether they are roasted or not.

Therefore, under the preservation of coffee, the editor explains to you what harm coffee beans will do when they are damp.

Damp damage to coffee beans:

1. The viscosity of coffee powder increases after being exposed to moisture, which will clog the coffee machine grinder and cause adverse effects on the machine.

2. Once coffee beans are exposed to moisture, they will easily deteriorate and become moldy, which will greatly shorten their shelf life and be harmful to their health.

3. It will affect the taste of coffee drinks.

Therefore, the four most important factors in the preservation of coffee beans are "sunlight, oxygen, temperature and humidity". Avoiding contact with these four points is the best way to store coffee beans.

Top five NG of coffee storage

1. Refrigerate in the refrigerator

Generally speaking, the best taste period for coffee beans is two weeks, which can be kept indoors in a cool place. If the coffee beans in large packages can be divided into vacuum bags when it is determined that there is no moisture in the coffee beans, this way can avoid making the coffee beans affected by moisture and deteriorating when they are taken out and used many times. Even if the cryopreservation can be purchased for an extended period of time, it is still recommended to drink it in a short time in order to enjoy the taste of the coffee itself.

If the frozen coffee beans are unsealed immediately after they are taken out, they will condense moisture on the surface because of the temperature difference, which will greatly destroy the quality! So do not unseal the sub-packaged coffee beans after they are taken out, be sure to leave them at room temperature and deice for 2 hours until reduced to room temperature before using.

Remember that the coffee beans that have been taken out of the refrigerator can not be put back to prevent moisture from affecting the flavor in the process of freezing and deicing.

2. Put it in a hot and humid environment

The weather in Taiwan is hot and humid, and if the rich water in the air seeps into the coffee beans, it will wash away the fragrant oil from the coffee surface, and even produce a bad smell. Therefore, coffee beans must be kept in a dry and cool place to prevent the beans from absorbing too much moisture or deteriorating due to high temperature.

Coffee beans are afraid of heat (sun, heat) and humidity-in fact, as long as you grasp the main points, the life of coffee beans will not break with you in advance:

→ is stored in a "cool" and "dry" place (without exposure to the sun, if you need to put it in a sealed jar, choose an opaque material, do not remove the original package of coffee, put the whole package in a sealed jar)

3. Massive exposure to oxygen

Roasted coffee beans have low moisture content, so they are not easy to rot. On the other hand, because coffee is a seed crop, it contains a high amount of fat, and if it comes into contact with oxygen, it will begin to become sour and rotten. Therefore, it is better to use a closed container that can isolate oxygen as far as possible. When preserving coffee, the most important thing is to isolate the light and the outside air. For this reason, almost most of the bags containing coffee are aluminized to block air and prevent light from entering.

The best way to preserve coffee is to use tinned cans to preserve coffee. But if you go to most coffee shops, you will find that many stores use transparent sealed bottles to preserve coffee. This is based on the consideration of display, because the store has to show the coffee before it can be sold. Coffee in this kind of coffee shop is usually sold quickly, so the possibility of bad taste due to improper preservation can be said to be very small.

4. Grind it into powder and preserve it

It is not recommended to save in the form of coffee powder. Even if the freshly roasted coffee beans, once ground into powder, their contact surface with the air will be greatly doubled and oxidized very quickly, the freshness of the coffee will be lost immediately, and because of the low moisture content of the coffee beans, it is easy to absorb moisture in the air, which leads to oxidation and corruption.

Therefore, the editor still recommends that you usually buy coffee beans, and if you have really ground the coffee beans into powder, drink them as soon as possible within the shelf life of two weeks.
