Is the coffee bean packing one-way exhaust valve important?

Coffee is the number one beverage in the world and one of the most popular drinks in the world.

Coffee beans are an important raw material for making coffee, for people who like to drink coffee, choose their own coffee beans to grind, not only can get the freshest and most ecological coffee experience, but also according to personal taste and preference to control the taste and quality of coffee. By adjusting the grinding thickness, water temperature, water injection and other parameters, make a cup of their own coffee.

I do not know if you have found that the bag containing coffee beans and coffee powder is not the same, the bag containing coffee beans often carries a hole shaped object, what is this? Why is the coffee bean packaging designed this way?

This round object is a one-way exhaust valve. This double-layer valve made of film is loaded into the baked beans, and the carbonates generated after baking will be discharged from the valve, and the outside gas can not enter the bag, which can effectively maintain the original aroma and essence of the roasted coffee beans. This is the most recommended packaging of roasted coffee beans, and you should try to choose coffee products with such packaging when purchasing.

Roasted coffee beans continue to release carbon dioxide, and the longer they are roasted, the less gas they release and the less fresh they become. If the roasted coffee beans use vacuum packaging, the bag will soon bulge, and the beans may not be fresh. As more gas is emitted, the bags become more bulging and are more likely to break during transport.

One-way exhaust valve means that the air valve only goes out and does not enter, and the coffee beans will produce carbon dioxide and other gases after roasting, which need to be slowly discharged. The one-way exhaust valve is packaged above the coffee bag and pierced on the surface of the bag at the position of the package check valve, so that the carbon dioxide extracted from the coffee beans after roasting can be automatically discharged outside the bag, and the outside air can not enter the bag. Effectively ensure that the coffee beans are dry and mellow, and will not open the bag because of the accumulation of carbon dioxide, and prevent the coffee beans from being accelerated by the outside air.

For consumers, the exhaust valve can also better help consumers to confirm the freshness of coffee, you can directly squeeze the bag at the time of purchase, the aroma of coffee directly from the bag to let people smell its aroma, so as to better confirm the freshness of coffee.

In addition to the installation of one-way exhaust valve, the choice of material should also be more careful, generally coffee beans will choose aluminum foil bag or aluminum plated kraft paper bag, this is because aluminum foil bag has good shading, can avoid coffee beans and sunlight and air contact, avoid oxidation, retain the flavor. So that coffee beans can be stored in the best packaging state, keep the fresh flavor of coffee beans.
