Food has shelf life, today coffee valve to share coffee beans stored notes.
1.Please purchase a coffee package with one-way degassing valve. Many of my friends, especially those who have just started to contact original coffee, buy coffee powder directly, and most of them cannot finish drinking it at once. This can damage coffee flavor. As the contact surface of coffee powder with the air greatly increased, fast oxidation, so the choice of one-way degassing valve with a coffee package, you can save the original flavor of coffee mellow.
2.Not recommended to put the refrigerator directly, can be sealed into. Although the low temperature in the refrigerator can slow the natural deterioration of the coffee, it is a good storage place, but it is easy to taste. Therefore, the application of vacuum preservation box to save more appropriate isolation of other omnivorous refrigerators to prevent moisture loss.
3.Freshly preserved coffee beans are kept for two weeks at room temperature. Similarly, you can feel the active changes in coffee beans.
4.It is recommended to use upright tank. The CO2 released by fresh coffee beans will remain at the bottom of the container forming an oxidation resistant layer to protect the coffee beans. The container is best placed upright to prevent CO2 loss in the can or in the bag.
5.It is recommended to use a separate vacuum tank with a mechanism that allows the air in the tank to be defocused to create a vacuum. Absolute vacuum: no oxygen and water vapor, is a great place to store coffee beans.
6.Coffee odor adsorption capacity, especially high-quality coffee is more sensitive. Smell refers to stink, rotten taste, tea flavor, milk taste, etc. Therefore, the coffee must be stored separately and can not be placed in the same sealed jar with other articles or different varieties of coffee beans.
