To seal in all the nutrients, flavors and juices, make sure to push out as much air as possible from the Yummy Bag before closing it. When you close the yummy Bag, you should hear both closing latches click.
Pro tip! For long-term storage of food or liquids, it helps to eliminate as much air as possible from the bag before closing it. After you’ve put your food or liquids in, close 1 of the 2 latches. Then, slowly dip the bottom of the Yummy Bag in water, slowly pushing it further down. You will see some air move to the surface and escape from the top of the Yummy Bag. Finally, push the last remaining air out and close the 2nd latch before taking the bag out of the water.
