In addition to emitting carbon dioxide, another important function of the one way degassingvalve is to prevent external oxygen from entering the packaging bag. Oxygen is the main culprit for the oxidation and deterioration of coffee beans. It can react with the oils and volatile compounds in the coffee beans, causing the aroma to dissipate and the taste to deteriorate. The sealing design of the one-way valve ensures that only gas flows out in one direction, avoiding the intrusion of oxygen, creating a low-oxygen, dry storage environment for coffee beans, and further ensuring the quality of coffee.
