The secret of coffee bean bags to keep coffee beans fresh-one-way exhaust valve
For professional baristas, please follow the coffee workshop (Wechat official account cafe_style)
Just like Buddha wants gold clothes and people want clothes, coffee beans need good bean bags to hold!
Of course, the bean bag packaging mentioned here is not only as simple as beautiful outside, the most important thing is to help keep the coffee beans fresh.
Generally, for roasted coffee beans, most of our coffee bags are made of aluminum foil, while sealed packaging with aluminum foil bags can avoid coffee beans coming into contact with light and air, resulting in rapid disappearance of fragrance and acidification and oxidation.
Another important secret weapon is the "one-way exhaust valve", which is even more special. after roasting, coffee beans will produce various substances and naturally emit carbon dioxide gas. if you let all those gases accumulate in the bag, it will affect the quality of the coffee beans and break the bag. At this time, the "one-way exhaust valve" on the bag can maintain the pressure in the bag, let the excess gas out, and can also isolate the light and air outside the bag, so that the coffee beans can keep the fresh original taste of the coffee beans in the best state of preservation and packaging.
So try to squeeze the exhaust valve on this bag, and you will find that air is discharged, and many consumers think it is designed to make people smell incense. Force, big mistake.
The next time you have doubts about the flavor of coffee beans, don't rush to squeeze the exhaust valve to try and judge, in fact, just ask the boss!
Note:
We have also seen a lot of coffee bean bags without breathable valves. Is this not good? actually, it is not!
Here, I would like to make it clear that the air can be kept in the bag by the way of inner folding, which is similar to the function of using breathable valves. in addition, taking environmental protection as the demand, reducing this kind of plastic packaging material is also a good starting point.
Therefore, the function of coffee bean bag can only help to keep the coffee beans fresh, and it is most important to drink them quickly while they are fresh.
