What is a fish vacuum and how does it work?
A fish vacuum, also known as a vacuum sealer, is a kitchen appliance designed to remove air from a bag or container before sealing it shut. This process helps preserve the freshness of fish and other foods by preventing the growth of bacteria and oxidation, which can lead to spoilage. The vacuum sealing process involves placing food in a specially designed bag or a canister, inserting it into the vacuum sealer, and then activating the machine, which sucks out the air and seals the bag or container.
The eliminated air creates a tight seal around the food, which significantly extends its shelf life. This is especially useful for fish, which is perishable and can lose its quality quickly. By vacuum sealing, you can store your fish in the refrigerator for an extended time or even freeze it without worrying about freezer burn or loss of flavor.
