Roasted coffee beans are easily oxidized by oxygen in the air, which makes the oil contained deteriorate, and the aroma also volatilizes away. After temperature, humidity, sunlight and other influences, the deterioration is accelerated, especially after multi-layer treatment of decaffeinated coffee beans. Oxidation is faster.

Coffee beans produce three times the volume of carbon dioxide after roasting, so the packaging of coffee is mainly to avoid contact with air oxidation and to treat the carbon dioxide produced by coffee beans.

Therefore, in order to maintain the aroma and quality of coffee, how to preserve coffee beans (powder) has become a university study.

Consumers often ask us: How does the aroma disappear after the beans are bought and opened? Coffee beans ground into powder to put after where is better ah? Will the coffee powder deteriorate due to moisture in the refrigerator? Is it right to put coffee beans in airtight cans? Wait, I believe these are also questions that everyone often doubts.

Actually! It's really not hard to preserve coffee beans (powder)~

Just remember, any food will have its best shelf life, of course, coffee beans are also the case, it is recommended to buy coffee beans, once open the oil-proof or tinfoil packaging coffee paper, to immediately pour coffee beans or coffee powder into the airtight jar!

After putting it into a closed can, it is best to put it in a cool place with low temperature and humidity, and it is recommended to drink it within two weeks. If there is no way, it is to vacuum package, make sure there is no moisture, and pack it in small packages. Squeeze out the air, so as to avoid taking it out many times, so that the coffee beans are affected by moisture, but it is easier to make the coffee beans deteriorate.

In general, baked beans can be stored for up to one month at room temperature, but about two months in vacuum, so we also recommend that you do not buy too much at once to store, even if you drink it every day, buy half a pound at a time. For ground coffee powder, it is generally stored at room temperature for up to one week, while it is stored in a sealed jar for two weeks.

Why do we say that it should be stored in an airtight container?

The biggest focus of preservation is not to contact the heat and moisture in the air, that is, to eliminate all external factors, so it is best to use vacuum bottles to preserve will be the best choice.
