The Function of Valve in Coffee Bean Packaging, Do You Know?

The following is the translation of the 'Bahasa' text to 'English' while preserving any html tags: "Coffee beans that have been roasted are usually placed in special aluminum foil packaging. There are holes or valves visible in the middle or on the side. It is an air valve that greatly determines the taste and aroma of the coffee beans inside."

What is Valve?

The following is the translation of the text from Bahasa to English while preserving any HTML tags: "Valve or air valve on the coffee packaging is like a special hole designed for the gas produced by the coffee bean roasting process to escape. Without the valve, the gas inside can cause the packaging to leak or damage the taste of the coffee."

"Function of Valve in Coffee Packaging"

The valve on the coffee bean packaging serves to address the problem of carbon dioxide gas release that occurs during the coffee bean roasting process. At that time, the beans will release carbon dioxide gas as a chemical reaction takes place. If this gas is not released, oxygen-containing air will enter, which can accelerate the oxidation process in the coffee beans and damage the taste and aroma of the coffee. With the valve, carbon dioxide gas can be released without opening the packaging.

Reasons Why Coffee Packaging Has a Valve

"After undergoing the roasting process, coffee beans slowly release CO2 over several days," said Monica Russel, founder and CEO of Acquired Coffee. This stage is called de-gassing and the process continues until the coffee beans are packaged."

Risk If Not Using Valve

Valve or tap on the coffee bag is very important because it can prevent the dangerous accumulation of carbon dioxide gas that can cause the packaging to leak. This valve is specifically designed to allow carbon dioxide gas to escape, but prevent oxygen and moisture from entering the bag. This not only ensures the safety of the coffee bag, but also ensures the optimal quality of the coffee taste by avoiding exposure to oxygen that can damage the flavor of the coffee beans.

"Does every coffee packaging have a valve?"

Not all coffee bags require a valve, depending on the roasting and packaging methods used. It is the de-gassing process that can cause the coffee bag to have holes. Therefore, if there is no CO2 release after packaging, then a valve is not necessary.

"Some special coffee roasters choose not to use valves, as they prefer their coffee beans to naturally release their gas before packaging, which can result in a more nuanced and complex flavor profile."
Russel said, quoted from Reader's Digest.

Russel said that the use of valves or holes is an industry standard and this also applies to packaging for dried fruits, roasted nuts, and tea. The use of these valves helps prevent food packaging from swelling, which can cause the food to spoil. Report: Aisyah Cryshanty / Source: Reader's Digest
