Can I put the coffee powder in the refrigerator? what's the best way to keep it?

Coffee powder can be placed in the refrigerator?

If you have to put coffee in the freezer, make sure you put it in the freezer immediately after you buy it. Coffee beans can be stored in freezers for up to a month, according to the National Coffee Association. Once you start using it, you must remove coffee from the refrigerator and store it in a cool, dry place.

The location of coffee storage is important, and the choice of packaging bags cannot be ignored. Whether you're storing coffee in a freezer for long-term storage or in a cupboard for daily use, remember to keep coffee in vacuum bags. Blue Bottle coffee shop professional barista also suggested that the bag should be equipped with one-way vent holes. The one-way vent not only ensures that the outside air cannot enter the packaging bag, but also allows the carbon dioxide in the coffee beans to be fully discharged. Coffee releases a certain amount of carbon dioxide after roasting. Only when the carbon dioxide is fully released can the taste of coffee reach its peak. Since humidity and oxygen can cause coffee to deteriorate faster, it is important to store coffee in sealed bags.

Don't worry, let's listen to the experts to analyze the benefits of putting coffee in the refrigerator. A team of researchers from the University of Bath, UK, in collaboration with local cafes, studied the effect of temperature on coffee grinding, ranging from room temperature to-196 ℃. Do you need liquid nitrogen?) The team published their findings in Scientific Reports, which caused quite a stir. They found that refrigerated coffee was better because the cooler the temperature, the smaller the gaps between the coffee molecules and the more neatly arranged they were, so we were able to extract more flavor for the same amount of coffee used during brewing.

Coffee brewing, like cooking, is a rigorous science, and ideally we should be able to extract as much quality flavor as possible from coffee beans. The degree of extraction depends on many factors, such as water quality, coffee contact area with water, and the temperature conditions of coffee grinding process according to recent research. The team said coffee powder with smaller, more orderly intermolecular spaces could extract more flavors and make coffee more delicious

Let's look at the impact of air on coffee quality. The flavor oil of coffee beans is easily oxidized, so before sealing coffee beans, the gas in the sealed can or coffee bag should be squeezed out and sealed. There is no room for air.

About temperature: high temperature will make coffee out of oil, increase the chance and degree of flavor oil oxidation by air. So friends sometimes keep coffee in the fridge, just like tea leaves. Here I just want to say that friends in the north please put coffee beans in winter as far away from the heating place. If you consider putting it in the refrigerator, you can, but check whether it is closed and put it in the refrigerator, otherwise your coffee will become a deodorant in the refrigerator.
