Various methods of vacuum preservation of coffee beans!

There are many ways to preserve coffee beans. Let's take a look at the ways to preserve coffee beans I found for you online:

Gas packaging, the most common packaging, using empty cans, glass, paper bags or plastic containers to pack beans, powder, and then capped or sealed packaging. Low preservation, and due to constant contact with the air, need to drink as soon as possible, drinking period is about a week.

Vacuum packaging, packaging containers (cans, aluminum foil bags, plastic bags) after filling coffee, draw out the air from the container. Although it is called a vacuum, it actually removes at most 90% of the air, and the surface area of the coffee powder is larger than that of the coffee beans, and even the remaining air can easily combine with the powder to affect the flavor.

Gas filling packaging, design a pinhole in the metal bag, after filling the coffee, pour inactive nitrogen into the bag, squeeze out the carbon dioxide pinhole. This method is more popular, but after all the gas is discharged, the oxygen is quietly drilled back into the bag from the pinhole.

Gas absorbent packaging, the absorbent made from deoxidizer and decarbonization is put into the bag, the air in the package can be easily absorbed, and the carbonation produced by coffee can also be inhaled, but the aroma of coffee will also be sucked away is its disadvantage.

UCC Euro packaging is the most ideal outer packaging for coffee at present, all of which are packed in the shape of beans rather than powder. It is similar to the pinhole metal bag, except that the gas in the bag can be discharged through the pinhole, while the unidirectional piston can prevent the oxygen from entering the bag.

The above are just a few preservation methods of coffee beans, of course, there are many preservation methods and techniques, but I think what has been mentioned above is already very good, so I will not tell you the preservation methods of coffee beans one by one.
