How to preserve the coffee powder?
About whether the coffee should be kept in the refrigerator: first of all, we should know whether the coffee is kept in the refrigerator and whether the coffee bag can be properly sealed is very important. Because moisture has a greater effect on coffee quality than temperature, it is particularly important to use sealing cans or coffee bag sealing rods to properly seal coffee bags. If the indoor temperature is too high after solving this problem, you can consider putting it in the refrigerator.
Let's look at the effect of air on the quality of coffee. The flavor oils of coffee beans are easily oxidized, so the sealed cans or the gas in the coffee bags should be squeezed before sealing the coffee. There is no room for air.
About temperature: high temperature will cause coffee to produce oil, increasing the chance and degree of flavor oil being oxidized by air. So friends sometimes put coffee in the refrigerator, just like keeping tea. Here I just want to say that friends in the north please put the coffee beans away from the heating as far as possible in winter. You can also consider putting it in the refrigerator, but check whether it is closed and put in the refrigerator, otherwise your coffee will become a deodorant in the refrigerator!
Among the many elements that affect the quality of coffee, the order from heavy to light is as follows: moisture, air, high temperature, sunlight. The change in the taste of coffee beans after being wet is that the coffee becomes more bitter, has no aroma and has a single taste. High temperature will cause the coffee to produce oil, and direct sunlight will make the coffee lose its aroma.
