Because the flavor oils of coffee beans or powder are easily oxidized, humidity and high temperature will also make coffee lose its aroma. Roasted coffee beans also contain high levels of carbon dioxide, which can affect flavor if kept in a bag for a long time.
How do protect the coffee from moisture and odor, and keep the aroma of coffee for a long time?ย ย
1, It requires a gadget that exhausts, we call it โOne side Degassing-valveโ, which allows carbon dioxide to escape from the inside of the bag without allowing external oxygen into the sealed bag.
As for grounded coffee/coffee powder, it requires that the valve need to be coated with non-woven fabrics, which can ensure that the powder does not clog the vent. As for coffee beans, then no need for non-woven fabrics.
The different volumes of coffee need a different valve. Coffee bags which under 16oz have required a valve with 5 holes, but if over 16 oz, they need a valve with 7 holes.
2, It also requires a suitable material structure, it needs a light-proof and high barrier.
