Coffee beans are a food that is susceptible to oxidation and moisture, so the correct storage method is essential to maintain its freshness and taste. When choosing a container for coffee beans, sealed jars and vacuum jars are two common options. The following will analyze these two containers and give the best choice.
First of all, the sealed can is a container with good sealing performance. It can effectively prevent air, moisture and light from entering the can, thereby slowing down the deterioration of coffee beans. Due to its good sealing performance, it can maintain freshness for a long time even after opening. In addition, the sealed can also has the advantages of being convenient to use and easy to clean.
However, when compared to vacuum tanks, sealed tanks have an obvious disadvantage: they cannot completely exclude air. Even with high-quality sealing materials, a small amount of air will still enter the container after long-term storage and come into contact with the coffee beans, causing deterioration to accelerate. In contrast, vacuum tanks create a truly oxygen-free environment by extracting the internal air and keeping it in a constant state.
In summary, although sealed cans are a viable option, vacuum cans are more suitable for the preservation of coffee beans. Vacuum cans can provide better preservation, extend the shelf life of coffee beans, and ensure that you can enjoy the taste of fresh roasting every time you use it. Therefore, when buying containers, we should give priority to vacuum cans.
