1. The method of preserving coffee powder is sealed and protected from light at low temperature.

2. Therefore, after the coffee powder is opened, it needs to be sealed with a professional sealing strip first, or put into a special sealed can, and then stored in a cool and dry place.

3. Because coffee powder has a strong adsorption force, if it is not sealed after opening, it is easy to adsorb external water vapor and odor, and if it is exposed to high temperature, it is more likely to deteriorate.
