Back in 2014, when we were dedicated to developing a whole new vacuum canister system, we bought and tried various storage containers in the market. We carefully analyzed the pros and cons of each product.
Finally, the Ankomn team simplified the options and designed two main product lines:
- Twisting Vacuum Canister
- Twisting Airtight Canister
providing solutions for everyday food storage and preservation.
But how do you choose between a vacuum canister and an airtight canister?
It's probably one of the most frequently asked questions after browsing our products. Here, I'll share the selection methods I personally use, making your decision-making process easier
Principles of Vacuum Sealed Containers and Airtight Containers
Before diving into the selection methods, let me briefly explain the principles of Ankomn's rotating vacuum and airtight containers.
How Ankomn Twisting Vacuum Canister Works:
Twist the lid, and the internal device will extract air from the canister, reducing moisture and oxygen to achieve preservation.
How Ankomn Twisting Airtight Canister Works:
Twist the lid to control airflow, blocking it. When the airflow is blocked, the canister enters a completely airtight state, isolated from the external environment until the next opening.
Now that you have a quick understanding of the principles,
let's move on to the main topic:
how to choose between a vacuum canister and an airtight canister!
Expert Tip #1: Use "Opening Frequency" to Choose Vacuum and Airtight Canisters
Let's consider two common scenarios together:
Scenario 1: Your coffee and nuts are opened every day, with a portion taken and then closed.
Scenario 2: Your seasonings, such as spice powders, are used only occasionally for specific dishes.
For Scenario 1, I recommend a vacuum canister. Daily openings introduce new oxygen and moisture, and a vacuum canister effectively removes these elements that can cause deterioration.
For Scenario 2, I recommend an airtight canister. Since you don't plan to open it frequently, once you block all airflow, the canister will remain in an airtight state, and its contents won't undergo significant changes over time.
In summary: "Choose a vacuum canister for frequent openings, and an airtight canister for infrequent openings."
In addition to this method, I'll share two additional criteria to make your decision even easier.
Expert Tip #2: Use "Oxidation or Moisture" to Choose Vacuum and Airtight Canisters
For foods prone to flavor changes due to oxidation, like coffee beans and nuts, use a vacuum canister. For ingredients susceptible to spoilage from humidity, like flour and rice, an airtight canister is suitable.
Expert Tip #3: Use "Food Shape" to Choose Vacuum and Airtight Canisters
For foods with irregular surfaces, like whole coffee beans, vacuum canisters are preferable. Processed powdered foods, on the other hand, are better suited for airtight canisters to prevent clumping caused by moisture.
Understanding these three tips should make your decision-making process clear and straightforward. Now, armed with this knowledge, you can easily choose the right container for your needs.
