Introduction to the flavor description of roasted coffee beans with a shelf life of how many days

How many days can roasted coffee beans be stored? Flavor Description Variety Introduction

Don't put coffee beans in the refrigerator:

1. The air in the refrigerator is cold and dry, and it is easy to evaporate the water inside the coffee beans, which makes the aroma lose.

2. There is too much bad smell in the refrigerator.

3. Due to the low temperature in the refrigerator, coffee beans will condense into water vapor covering the surface of coffee beans when they are taken out of the refrigerator. After grinding, these small water droplets will form coffee powder into lumps, resulting in uneven brewing.

4. As mentioned above, after the coffee beans are roasted, the internal reaction continues. If the coffee beans are put into the refrigerator at this time, the coffee beans will be cooled and stop the internal reaction, resulting in the loss of flavor.

Keep it in a cool, dry place. 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.

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.
