Four common types of coffee packaging on the market
1. Flexible non-airtight packaging: This is the most economical packaging. Usually used by small local roasters because they can guarantee prompt supply. Coffee beans can be consumed in time. Coffee beans in this packaging can only be stored for a short time.
2. Air-tight packaging: After filling the coffee, vacuumize and seal it. Due to the formation of carbon dioxide during the roasting process, this packaging can only be packaged after the coffee has been left for a period of time to degas it, so there is a storage interval of several days. Coffee beans sit longer than ground coffee. The cost is low since it does not need to be separated from the air during storage. Coffee in this packaging should be used up within 10 weeks.
3. Packaging with one-way exhaust valve: After roasting, the coffee is placed in a special one-way exhaust valve. This exhaust valve allows gas to exit, but not to enter. A separate storage stage is not required, but there is a little loss of aroma due to the outgassing process. It avoids the formation of spoilage taste, but it cannot prevent the loss of aroma.
4. Pressurized packaging: This is the most expensive way, but it can keep coffee for two years. After a few minutes of roasting, the coffee is vacuum packed. After adding some inert gas, the proper pressure is maintained inside the package. The coffee beans are kept under pressure, which allows the aroma to flow over the fat, thereby improving the aroma of the drink.
