Recommended for household coffee beans: there is no brand of coffee beans, depending on the origin and roasting. Freshness is also very important, Taobao can buy good beans, of course, taste, price, according to their own taste and demand and budget. Taobao also has good sellers, with large baking equipment that the family does not have, so take a closer look at the baking equipment and bean seeds used when choosing a store. From the gradual progress of blending beans to bidding beans, you can try different varieties to determine your favorite taste, of course, those who want to experience the fun of baking beans can also choose to buy online baking machines and raw beans to bake by themselves. Beans are generally required to be consumed within a month, do not buy too much at once, drink up and then buy. After opening the bag, it is better to keep it in a metal sealed jar with a rubber gasket.

Many friends bought coffee beans, which led to the rapid loss of coffee flavor due to improper storage. So today I will tell you how to store coffee beans at home so that the flavor of coffee beans can be lost more slowly.

First of all, it is clear that for roasted coffee beans, the shelf life is not very important, because they are very long, shelf life is what we should pay attention to. As for coffee powder, er, there seems to be no way to prolong the shelf life, so let's freshly grind it in order to drink good coffee.

Freshly roasted household coffee beans oxidize with time exposure to oxygen, their oil quality deteriorates, their aroma gradually volatilizes, and their aging is accelerated by temperature, humidity, sunshine and other preservation environment.

When the coffee bean comes into contact with the air, its flavor begins to lose, and the area of a complete coffee bean in contact with the air is limited, but the coffee bean forms a powder after grinding, and the surface in contact with the air is magnified thousands of times. there are countless noodles in contact with the air, resulting in a rapid loss of flavor, usually extraction should be carried out within 15 minutes after grinding. Therefore, when making coffee, grind and use it as much as possible, so as to ensure the quality of each cup of coffee. Never buy directly ground coffee. Say the important things three times.

Therefore, in order to prolong the shelf life of coffee beans, how to package and preserve coffee beans has become a special work.

Coffee beans gradually release carbon dioxide after baking, and coffee beans are usually undrinkable after roasting, because they contain a lot of carbon dioxide and pyrotechnic odors produced by baking, so they need to raise beans. Generally, the time of growing beans is determined according to different baking degrees, the time of baking is shorter than that of shallow, and the time of baking is deeper, and the time of cultivating beans is longer. Generally, it is more reasonable to raise beans for about seven days. The flavor of coffee beans reaches the best time to taste in about seven to ten days, and the flavor continues to develop, and it will gradually decrease after a month, so we recommend that freshly roasted coffee beans are finished within a month, preferably no more than two months, and will not go bad, but the smell will be weaker and weaker.

Therefore, the packaging of coffee is designed according to the characteristics of roasted coffee. Packaging should not only avoid contact with air oxidation, but also need to deal with carbon dioxide produced by coffee beans, of course, the safety of contact with food must be put in the first place.

The enemies of coffee beans are: oxygen, humidity, temperature, light, so the key to preservation is: sealing, protection from light, moisture, exhaust.

Based on the above theoretical principles, we need to choose the appropriate containers for the preservation of coffee beans.
