In order to extend the shelf life of coffee beans, you need to understand the three enemies that make coffee beans go bad!

Temperature.

When coffee beans encounter sunlight, there will be chemical changes, water evaporation, beans will begin to produce a unique odor, the main factor is that the influence of sunlight and temperature will promote the oxidation of coffee bean fat, coupled with high temperature is easy to volatilize the aroma of coffee and the excellent substances inside coffee beans. Therefore, when preserving coffee beans, be sure to avoid sunlight and ultraviolet light, and keep them in a cool, dark place after sealing.

Humidity

Freshly roasted coffee beans, with a water content of less than 5%, are the best dry state of coffee beans, but coffee is prone to moisture due to improper environmental temperature and humidity, resulting in deterioration of compounds. Moist coffee beans are easy to let mold grow and produce ochratoxin, which is a colorless crystal compound, which has a very serious negative impact on human health.

Oxidation rate

In the roasting process of coffee beans, the water of raw coffee beans is slowly released, the weight decreases, the color deepens, and the volume begins to expand, at this time the oil and aroma in the coffee will be slowly released, while the oil in the coffee beans, if it comes into contact with oxygen, it will produce oxidation, if the degree of oxidation is too intense, it is easy to cause deterioration and decay.

Use opaque cans to store coffee beans

"Light" is the medium to accelerate the oxidation of coffee, which will increase the oxidation rate of coffee and accelerate the deterioration of coffee.

If you can, please choose a bean storage tank with an opaque outer layer, or a vacuum tank can pump out the air inside the tank, isolating oxygen and moisture.

Forming a vacuum preservation state is a good way to preserve coffee beans.

Therefore, the correct way to preserve the coffee beans should be to put the coffee beans in the jar and add a simple cloth or dark paper to cover the outside of the jar.

The receiver should be placed in a shady place out of the sun. If you need to brew coffee and grind the coffee beans, you can effectively slow down the oxidation of coffee beans.

Don't put the coffee beans in the refrigerator.

Opinions vary on the Internet as to whether coffee beans should be put in the refrigerator or not. But we still advise you not to put coffee beans in the refrigerator.

The reason is that when taking out coffee beans from the refrigerator, once exposed to room temperature, it is easy to make the appearance of coffee beans produce condensate.

At this time, the coffee beans will soften after absorbing moisture, causing the coffee beans to become damp and slowly go bad. Therefore, it is best to avoid refrigeration or cryopreservation as far as possible.

Coffee processing methods are often heard of a variety of treatments, different treatments will give different flavors, of course, there will be a gap in price
