Coffee is a must-have drink for many people every morning. However, have you ever wondered why coffee beans are always kept in a light-proof container? Therein lies the secret of the black magic.
First, we need to understand the internal structure of coffee beans. The surface of coffee beans is covered with a layer of fats and oils, which are easily affected by sunlight and oxygen and undergo oxidation reactions. When coffee beans are exposed to sunlight, they quickly lose their freshness and develop an unpleasant odor.
Secondly, storing coffee beans in a dark environment can extend the shelf life of coffee beans. Sunlight contains ultraviolet radiation, which can destroy nutrients in food and accelerate food spoilage. Similarly, storing coffee beans in the sun for too long will cause them to lose their original rich aroma and taste.
In addition, avoiding exposure to sunlight can also prevent humidity from damaging coffee beans. High temperature and high humidity environments can easily cause coffee beans to absorb moisture, which affects their quality and taste. Therefore, storing coffee beans in a light-proof container can effectively prevent humidity from having an adverse effect on them.
Finally, keeping coffee beans away from light also helps preserve the aroma components in the beans. Sunlight destroys the volatile compounds in the beans, which are key components that give coffee its unique aroma and flavor. By keeping coffee away from light, you can ensure that these valuable aroma components are preserved intact.
In summary, storing coffee beans in a dark environment has multiple benefits. It can extend the shelf life, prevent oxidation, reduce nutrient loss, prevent moisture damage, and preserve the aroma components of the coffee beans intact. Therefore, after purchasing fresh coffee beans, be sure to store them in a dry, cool place away from direct sunlight.
