The Solis vacuum machine: What can you do with it? Vacuum food. Why would you do that? Because it lasts longer or because it marinates better! Restaurant chefs are using vacuum technology for many years now. They divide meat, for example, into portions and put it in a vacuum bag, sometimes with marinade, so it last longer and can extract the flavors extra well. In these sales you will find the vacuum foil and bags you need for the Solis vacuum machine.
