Description
One of the chemical reactions mentioned above causes carbon dioxide to be released from the beans. Freshly roasted coffee will emit CO2 for up to 7 days after it is roasted. Roasted coffee is sensitive to light, oxygen and moisture and because of this, finding packaging that will prevent the coffee from going stale used to be extremely difficult.
The problem was that if the beans were placed in a hermetically sealed environment, the package had a tendency to burst due to the internal pressure of the excess gases. To solve this problem, a package had to be created that allowed the gas inside the bag to escape without letting outside oxygen in. Thus, the degassing valve was invented. This small device, when applied to a foil bag or pouch, will allow freshly roasted coffee to be packaged almost immediately after roasting and will keep the product safely away from the degenerative effects of oxygen, light, and moisture. This innovation in packaging has proven industry changing and is now being used worldwide.
