How to vacuum pack food?
Vacuum packing is very easy and can be done at home too. There are various equipment and machines available that can seal pack the food. These are called vacuum sealers and they remove air from the package before closing it. You can use the following things for food preservation vacuum packing:
An automatic machine starts the sealing process when a plastic bag is placed inside it. It uses sensors which start working when the button is pressed and the packet is placed inside it. The machine withdraws air from the plastic bag and starts sealing it. This method is used for sealing plastic bags or pouches.
A manual pump can also be used for food preservation vacuum packing. The manual vacuum packing is done for containers or jars rather than plastic bags or pouches. To do so, a container with a nozzle should be used where the manual pump can be inserted for drawing the air. Once the air is drawn using the manual pump, the nozzle closes itself so that no air can enter it.
