Hi Dave, I received Hello I truffles in a sealed bag (not vacuum) from a supplier in the Netherlands. Hello I receievd truffles in a sealed bag(not vacuum) can I put them in a topperware with silica baggage? The vacuum packed one was in cupboard for 2 weeks unopened and now in fridge. The vacuum pack prices roughly the identical as the food dryer, a few tens of euros, but along with this use you'll uncover many different uses that make it a purchase you will recognize over time: meat, fish, cheese, there are lots of perishable merchandise that improve their shelf life within the refrigerator or freezer with vacuum protection. For those who open them and go away them refrigerated their shelf life will probably be shortened, should you open them and go away them at room temperature they are going to spoil quickly.
