1. Gas-containing packaging.

The most common packaging, with glass cans, paper bags or plastic containers to package beans, powder, and then cover or seal packaging. Low preservation, and because of contact with the air at all times, need to drink as soon as possible, drinking period of about a week.

2, vacuum packaging.

Packaging containers (cans, foil bags, plastic bags) After filling with coffee, evacuate the air inside the container. Although it is called vacuum, it actually removes up to 90% of the air and is not suitable for preserving coffee powder.

3. Gas filling packaging.

A pinhole is designed on the metal bag. After filling the coffee, inert nitrogen gas is injected to squeeze out the carbon dioxide in the bag from the pinhole. This method is more popular, but after all the gas glass is exhausted, some air will be drilled from the pinhole into the bag.

4. Gas sorbent packaging.

The sorbents made of deoxy and decarbonization are placed in packaging bags, and the air in the packaging can be easily absorbed, and the carbonic acid gas generated by coffee can also be absorbed, but the disadvantage is that the aroma of coffee will also be absorbed.

5, UCC Rome packaging.

This is currently the most ideal coffee packaging, all in the form of beans rather than powder packaging. It is similar to a pinhole metal bag, except that the air inside the bag can be exhausted through the pinhole, while the one-way piston can prevent the air outside the bag from entering the bag. Coffee makers cool the beans immediately after roasting and pack them, pumping nitrogen into the bags to vent the gases. Although this packaging is the most ideal, but the material is expensive, high cost, currently only the selection of coffee companies will use this packaging method.

1. Use vertical sealed cans. Because carbon dioxide has a higher specific gravity than air, fresh coffee beans release carbon dioxide that is stored at the bottom of the container, which acts as an antioxidant layer to protect the coffee beans. In terms of containers, it is best to use vertical placement to prevent the loss of carbon dioxide in sealed cans or bags, so it is more appropriate to choose vertical sealed cans with upward openings.

Second, use a long spoon to remove coffee beans. The same principle as the specific gravity of carbon dioxide, so carbon dioxide deposits at the bottom, so when taking coffee beans do not use the pour way, otherwise the essence of the container, that is, carbon dioxide, will also be at the same time be poured out.

Third, the vertical type of sealed can is the best. Since light is the catalyst of oxidation, choosing a vertical airtight tank with no light transmission can slow down the rate of oxidation. Although most opaque cans are transparent, it is recommended that coffee beans stored in the can be handled in a way that can cover the transparent lid.

4. Use vacuum tank. There are many vacuum tanks on the market, most of which are pulled or taken out, and the air in the tank is pumped out to form a vacuum state. There is no oxygen and moisture in the vacuum state, so it will also be a method of storing coffee beans.

5. Place it in a cool and dry place as much as possible. Roasted coffee beans, if placed in a high temperature state, will easily lead to volatilization of coffee aroma and internal fine substances. Therefore, it is best to avoid placing coffee cans in high temperature environments, and it is best to choose to place them in cool and dry places.
