Can coffee beans and coffee powder be refrigerated or frozen in the refrigerator?

Frozen coffee beans and coffee powder will attract moisture, which will freeze on the surface of the beans. at the same time, there are many pores in the roasted coffee beans, and freezing will seal off the water, thus terminating the natural chemical reaction of the beans. Therefore, the flavor of thawed coffee beans or coffee powder is much better than that at room temperature.

What about refrigeration? And you can't! The circulating moisture in the refrigerator is the biggest natural enemy of coffee beans or powder, and the freezer is full of odors, unless you want to do scientific experiments to see how long it takes to destroy a bag of good coffee beans. By the way, after grinding stale coffee beans into powder, it can be a very effective dehumidifier and deodorant.

Will coffee powder be easier to preserve than coffee beans? NO!

In general, coffee beans can be preserved for about a year without being sealed. After exposure to air, it is best to eat up within 14 days to prevent moisture. In this way, how does oxygen affect the quality of coffee beans? Coffee beans will deteriorate because of oxidation, and the longer they are exposed to the air after baking, the less fresh the coffee beans will be, and the worse the flavor of the brewed coffee will be, not to mention the coffee powder that has been ground has a larger surface area in contact with the air. it's more likely to deteriorate.

In 1999, the American Fine Coffee Association (SCAA) publicly adopted the definition of "freshly roasted coffee": no matter how it is packaged, it must be brewed within 3-7 days of baking and immediately after grinding into powder. So, if you have bought a whole bag of coffee powder to go home, the best way is to finish drinking!

General arrangement of preservation tips for coffee powder

Sealed cans are filled:

Put an end to the possibility of damp coffee powder caused by oxygen

How long is the shelf life of coffee powder?

Focus on:

1. Don't buy too much at once.

two。 Use opaque aluminum foil bean bags provided by merchants and equipped with one-way exhaust valve

3. Use bean cans, choose opaque materials, and clean and keep dry before pouring in new beans.

4. If you have finished drinking coffee powder for more than 2 weeks, please keep it frozen for safety.

5. Frozen coffee can be brewed after rewarming.

In fact, it depends on the degree of individual requirements for the quality of coffee. Based on the difference in people's sensitivity to smell and taste, how many people can taste the difference between a week and a week, or a week and a month? Therefore, as long as you know how to preserve coffee powder, one month is generally acceptable.

The shelf life of coffee powder is very short. After grinding into powder, as the surface area increases, oxidation is accelerated, and a large amount of aroma and flavor will be lost within a few minutes. Therefore, unless you have no choice, such as in the office, going out, etc., it is best to buy fresh coffee beans and grind and brew them before drinking them.
