Compared to instant coffee, more and more people prefer to buy whole beans and use the coffee mechanism to make freshly ground coffee at home. With the expansion of the coffee market, in addition to eating out, more people begin to make their own coffee at home.

Recently, members of Taiwan's Costco store received a notice saying that as the bags of a small number of organic Sumatran coffee beans were found to be incompletely sealed, they called on people who bought this product between May 22 and June 9 to check the packaging of the products. If they have doubts about not eating them, they can take the products to the store to return them.

Some netizens said that because the backglue of the coffee bean package needed to be torn open to know whether the seal was complete or not, without paying attention, he had finished drinking a pack. Another netizen also said that after receiving the notice, he found that there was a big hole in the package. I really didn't know if I didn't look at it carefully.

Another netizen said that seeing the recent news report that there was a mistake in the packaging of the brand's coffee beans, they inspected an organic Ethiopian coffee bean purchased a few months ago and was surprised to find that the seal of the package was incomplete. Fortunately, I haven't eaten it yet.

It can be noticed from the pictures provided by netizens that the reason for the opening of the coffee bean bag is not entirely because the coffee bean package is not sealed, but also because the hole of the one-way exhaust valve in the bag is too small / there is a problem in design.

No matter what the roasting degree of coffee beans, after baking will release a large amount of carbon dioxide, when the one-way exhaust valve plays a very important role. Coffee beans release carbon dioxide in a completely sealed environment, but the carbon dioxide cannot be discharged through the valve, which will lead to excessive gas pressure in the package and open the seal of the bag.

In this case, will the coffee beans go bad? No, I won't! As long as coffee beans are stored in a dry and cool place, there is generally no mildew! But this is only for the state of the coffee bean itself.

When coffee beans are exposed to the air for a long time, the flavor molecules in coffee beans "escape" with the release of carbon dioxide. Although the organic matter in coffee beans will not have any health changes, the flavor of coffee will fade and the overall taste of coffee will become dull and tasteless.

Although the bag was opened this time, it may not be entirely due to incomplete sealing. However, no matter what causes the seal to be opened, the distributor has the obligation to change the product or refund the product.

With the increasing demand for coffee, many partners have the habit of hoarding coffee beans / coffee powder, and it has become a common practice to buy more than one month at a time. The best storage conditions for coffee beans / coffee powder are dry and cool. As a common food fresh-keeping equipment, the refrigerator is available in every house. at the same time, in order to slow down the oxidation rate of coffee beans, many coffee drinkers can think of putting the purchased coffee beans in the refrigerator.

However, due to the large temperature difference between inside and outside the refrigerator, when the coffee bean / coffee powder is taken out from the refrigerator, the large temperature difference is easy to cause water vapor condensation in the air and make the coffee bean / coffee powder damp.

Nowadays, the packaging of coffee beans purchased on the market mostly has an one-way exhaust valve design, the excess gas in the bag is discharged through the exhaust valve, when the air pressure in the bag decreases, the valve closes, and external air and water vapor cannot enter the bag. In other words, coffee beans are less likely to get damp when the bags are intact and at room temperature. In order to avoid incomplete packaging, friends are advised to check the outer packaging of each packet of coffee every time they receive the goods.

Want to maintain the original flavor of coffee beans, but afraid of dampness, in fact, the way is very simple, that is to show off a pack and then buy a pack.
