The preservation of coffee beans the preservation method of coffee in the family

Coffee produces a large number of aroma components after roasting, which is why coffee beans can produce mellow coffee drinks. But the aroma of coffee is very easy to lose, and it will always come out of the coffee until it is completely evaporated. If the aroma of the coffee is lost too much, the coffee produced will not be very fragrant. The reason why we can drink strong coffee is due to its scientific packaging and preservation.

Coffee is different from ordinary food in that its aroma component is its life. Coffee without aroma has no meaning to exist. Therefore, the key to coffee preservation is how to best retain the aroma components in the coffee.

Coffee beans retain aroma ingredients much more easily than coffee powder. For coffee shops, purchasing coffee is a basic way to preserve the aroma of coffee. For families, it is also possible to buy coffee beans instead of coffee powder. If you have no choice but to buy coffee powder, be careful not to buy more coffee powder than you can use in 1-2 weeks. Otherwise, the coffee will not have the flavor it should have. In addition, you should try your best to sell according to the production tools you use to help you grind the coffee beans into powder. To avoid buying coffee powder that has been on the shelf for a long time, such coffee powder has lost a lot of aroma ingredients.

(1) the shelf life of coffee

General coffee packaging mentioned: "shelf life" is to reflect the coffee aroma components can be retained to a certain degree of shelf life. Instead of reflecting the time when coffee may go bad. Because coffee is different from ordinary food, its temperature is very low and it is not easy to deteriorate.

After making coffee, the waste coffee grounds are easy to get moldy, and it is because the coffee pool dregs become wet that they go bad and mildew. If the coffee grounds are dried, there will be no mildew.

Generally speaking, the shelf life of coffee in aluminum foil bags is 12 to 24 months. In the absence of an international standard in this regard, the shelf life offered by different coffee companies will vary slightly.

(2) the preservation method of coffee in the family.

The preservation of coffee here refers to both coffee beans and coffee powder. Many people keep their food in the refrigerator in order to avoid spoilage. The principle, of course, is to reduce the activity of food by lowering its temperature, so as to prolong its shelf life.

As we have mentioned above, unlike ordinary food, coffee has a very low moisture content and is not easy to deteriorate, and its shelf life is set for aroma. Therefore, putting coffee in the refrigerator is not good for it, on the contrary, it affects the aroma composition of coffee. Coffee should be kept at room temperature.
