Generally speaking, we think that this is due to the oxidation of the oil in coffee beans, but this is not the main reason. Because coffee beans are rich in a variety of antioxidants, the process of oil oxidation is very slow, and we detect the time when the flavor of coffee beans changes.

Why does the taste of coffee beans change? Generally speaking, we think that this is due to the oxidation of the oil in coffee beans, but this is not the main reason. Because coffee beans are rich in a variety of antioxidants, the process of oil oxidation is very slow, and we detect the change of coffee bean flavor much earlier than the time of oil oxidation. The change in the taste of coffee beans is actually a change in flavor.

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 to, for example, when you can't grind beans in the office or out, you'd better buy fresh coffee beans and grind and brew them before drinking them.

1. Freezing slows down the decay period and preserves the fresh flavor-after freezing, coffee beans will remain where they are when you put them in the freeze, and then decay very slowly, almost for a long time unless your refrigerator breaks down.

two。 Freezing can give your delicious coffee enough time to develop a real flavor-if your preserved coffee beans are really good beans, then freezing will give your beans enough time to slowly release trace elements and aromatic substances.

Fresh beans will exhaust strongly in the first few days, if you are dehydrated at a higher temperature, or for too long, or if you use a larger air volume or secondary baking, it will accelerate the discharge of trace elements and aromatic substances. the best taste period for coffee will be only a few days, such beans are basically difficult to preserve, only to drink as quickly as possible. At this time, after you cool it, you can put it directly into the freeze and you can slightly prolong the taste period.
