Food vacuum sealers are a great way to keep the food fresh and retain its nutrients. These foods are known to stay fresh not just for days but even weeks and months for some ingredients. However, it is important to be careful of what is being packed in bags to ensure that one does not exceed the expiry date of the food. Here are some tips and tricks to make food vacuum sealers even more efficient. 1. Label the bags When vacuum-sealing food in bags, it is important to label the bags correctly. Some bags come with their own label, which can be used to easily write down the contents. It’s also a good idea to include the date of packaging and the expiry date on the label to ensure food safety. 2. Freeze liquids One trick to seal liquids in food vacuum sealers is to freeze them first. Once frozen, put them in the sealers and put them away. This will only take a couple of extra hours of work but will be rewarding as it creates no mess while sealing liquids that are flavorful when thawed. 3. Use oxygen absorbers These are small packets that are easily available in the market.
