New options for coffee bean storage: airtight cans vs vacuum cans

Airtight jars and vacuum jars: new options for coffee bean storage

How to preserve coffee beans has always been a hot topic among coffee lovers. With the advancement of technology, many new types of storage containers have emerged, among which the most popular ones are sealed cans and vacuum cans. This article will compare these two containers from different angles and explore their advantages and disadvantages in keeping coffee beans fresh.

Design and materials

First, let's take a look at the differences between sealed jars and vacuum jars in terms of design and material. Sealed jars are usually made of glass or ceramic, and are exquisite and transparent; while vacuum jars are mostly made of plastic or metal, and are lightweight and durable.

From the appearance, the sealed can is more elegant and graceful, and can also serve as a decoration when placed in the kitchen; while the vacuum can is more practical and simple, and is easier to operate when traveling or using outdoors.

Gas barrier properties

Next, let's compare the gas barrier properties of these two containers. Sealed cans are usually sealed by rubber gaskets or metal threads, which can effectively prevent air from entering the container; while vacuum cans use a vacuum pump to extract the air inside the container to form a vacuum environment.

In this regard, the vacuum tank has obviously better performance. Due to the absence of oxygen and humidity, the oil and aroma substances in the coffee beans are not easily decomposed and volatilized, thus maintaining freshness for a longer time.

Convenience and service life

Finally, let's compare the differences between these two containers in terms of convenience and lifespan. Since airtight cans are made of glass or ceramic, you need to be careful in daily use to avoid collisions and breaks; while vacuum cans are mostly made of plastic or metal, which has an advantage in durability.

In addition, the vacuum tank has an obvious advantage that it can be reused. You only need to clean it regularly and replace parts such as the vacuum pump to continue using it; while the sealed tank requires more careful maintenance to prevent the sealing performance from deteriorating.

in conclusion

In summary, both sealed cans and vacuum cans have their own advantages and applicable scenarios. If you pursue an elegant appearance and exquisite decorative effects, and do not have high requirements for storage time, then a sealed can will be a good choice; if you pay attention to the freshness of coffee beans and want to store them for a long time, then a vacuum can is more suitable.

Finally, please choose the container that suits you according to your personal needs and actual situation, and pay attention to maintenance and cleaning during use. Only by using these containers correctly can you maximize the freshness of the coffee beans and make every cup of coffee a wonderful experience.
