Coffee beans gradually release carbon dioxide after baking, and coffee beans are usually undrinkable after roasting, because they contain a lot of carbon dioxide and pyrotechnic odors produced by baking, so they need to raise beans. Generally, the time of growing beans is determined according to different baking degrees, the time of baking is shorter than that of shallow, and the time of baking is deeper, and the time of cultivating beans is longer. Generally, it is more reasonable to raise beans for about seven days. The flavor of coffee beans reaches the best time to taste in about seven to ten days, and the flavor continues to develop, and it will gradually decrease after a month, so we recommend that freshly roasted coffee beans are finished within a month, preferably no more than two months, and will not go bad, but the smell will be weaker and weaker.

Therefore, coffee packaging should not only avoid contact with air oxidation, but also need to deal with the carbon dioxide produced by coffee beans, of course, the safety of contact with food must be put in the first place.

The enemies of coffee beans are: oxygen, humidity, temperature, light, so the key to preservation is: sealing, light protection, moistureproof, exhaust.

Vacuum tank preservation

The vacuum tank can pump out the air in the tank to form a vacuum, which is a good way to store coffee beans without oxygen and water vapor, but it should be noted that this method can only delay the shelf life of coffee beans. It does not guarantee that the coffee beans are fresh for a long time. There are more and more vacuum cans on the market, and the price is getting cheaper and cheaper. The quality is mixed, but the quality is reliable. The one of poor quality is not as good as that of the original package. This is recommended for household use. If you drink slowly, you can consider a bag that takes more than two months to finish.

Sealed pot preservation

Using sealed cans to preserve coffee beans is also a good way, but it should be noted that the quality of sealed cans must be good, if the quality is too poor, it is better to use the original packaging bag, there is another point, do not buy transparent cans for the so-called beauty, light can improve the speed of coffee oxidation, it is recommended not to buy transparent ones. Some commercial coffee shops and other use environment, many people will use large transparent sealed cans, this specific treatment, because transparent cans can directly see baked beans, the business environment helps consumers to choose, in addition, coffee shops use a large amount of beans, so this is determined according to the usage, and there is no consideration for prolonging the shelf life if one can be used up in a few days.

Bagged preservation

After unpacking the bagged coffee beans, be sure to fold the opening and clamp it with a clip to avoid contact with the air. At the same time, after sealing the mouth of the bag, put the bag into an opaque sealed jar for storage, the opaque jar can slow down the speed of oxidation. Finally, store the jar in a dry and cool place. Nowadays, there are many vacuum cans specially used to preserve coffee beans on the market, and their prices are relatively cheap, so they are good tools for storing coffee beans.

Refrigerator preservation

If the unopened coffee beans can be put in the refrigerator, the temperature decreases, the oxidation rate of coffee beans is bound to slow down. However, if coffee beans have been opened, it is not recommended to put them in the refrigerator. Among the important elements that affect coffee, moisture has the greatest impact on the taste of coffee. Coffee beans will absorb moisture and the taste will deteriorate to a great extent.
