How to keep the coffee in the refrigerator correctly?
If you really want to put the coffee in the refrigerator, it is best to divide the coffee into small parts one by one and boil it with a bag every time you drink it, so that the coffee can preserve its freshness. After roasting, coffee beans produce an oxidation process that automatically releases carbon dioxide. A good coffee roaster will put the freshly roasted coffee beans in a marijuana bag and "bake" them in real time for 12-24 hours to inflate the heart of the coffee to release the sesame oil of the coffee, then put it in a sealed storage tank and pack it for sale. Generally put in the supermarket packaging will use "vacuum" method, into the "nitrogen", as well as the use of "one-way breathable valve" and other ways to save.
In general, the shelf life of coffee beans can be one year, while coffee powder may be 6-9 months, and after drinking, the storage time will be relatively short, but it also depends on the storage mode. As the name implies, "vacuum" means that the gas in the package is extracted by a vacuum machine, so that the residual carbon dioxide and air cannot be left, but some coffee aroma will be removed at the same time. The method of "vacuum" can preserve the taste of coffee as much as possible, and it will be preserved for a long time. Entering the "nitrogen" is to blow away the air in the coffee, by using the nitrogen to surround the aroma of the coffee beans to preserve the original flavor. The "one-way breathable valve" releases carbon dioxide from the coffee bag and prevents air or other gases from entering the bag from the outer layer, thus affecting the taste of the coffee.
The best way to preserve the coffee is to put the original bagged coffee in some sealed fresh bags and into a sealed bottle with a tight lid. just put it in a cool storage cabinet. the most important thing is that there can be no heating nearby, such as the oven or refrigerator, so as to prevent the coffee from being heated and causing the coffee to expand again and release carbon dioxide. If a friend buys coffee, he must read the instructions on the package carefully, because if the coffee is put into "nitrogen" during sealed storage, the coffee should be brewed for at least an hour before drinking, otherwise it will taste strange.
