Preservation methods of coffee beans

Bean friends who often buy coffee beans all know that the shelf life of roasted coffee beans is not very long compared with raw beans. Raw beans can be kept for a long time as long as the temperature is suitable and is not affected by moisture. If the cooked beans are not packaged properly, they will soon lose the best flavor. Uncle bean once taught us how to preserve cooked coffee beans.

If the packaging is good (with oxygen-resistant aluminum film nitrogen-filled packaging, it can be more than 1 year). If it is ground into powder, the best flavor will be lost in 24 hours, of course, it is not impossible to eat in 24 hours, but the flavor of the extracted coffee is very different.

How to preserve coffee beans:

1. When the bagged coffee bean is unpacked, the opening must be folded and clamped with a clamp to avoid contact with the air. The coffee bean will produce oxidation reaction when it comes into contact with the air, which will affect the original flavor of the coffee bean and greatly reduce the quality of the extracted coffee.

2. After sealing the mouth of the bag, put the bag into a sealed can for storage. It is best to use a container with good sealing performance such as Le buckle.

Do not put coffee beans in the refrigerator; store coffee beans in a dry and cool place.

When storing coffee beans, be sure to avoid damp coffee beans. This is because:

1. The viscosity of coffee powder increases after being exposed to moisture, which will clog the coffee machine grinder and cause adverse effects on the machine.

2. Once coffee beans are exposed to moisture, they will easily deteriorate and become moldy, which will greatly shorten their shelf life and be harmful to their health.

3. It will affect the taste of coffee drinks. It is recommended that poorly preserved coffee beans should not be eaten.
