For those who cook large quantities of food, FoodSaver vacuum packaging systems offer excellent protection against food spoilage and freezer burn. This jar sealer attachment fits on wide-mouth mason jars and is for use with any FoodSaver machine that has an accessory port. The top forms a tight seal on mason jars while the tubing removes air from the jar with the help of a FoodSaver machine. The jar sealer works equally as well in packaging liquid foods, such as jams or chocolate sauces, as it does for dry goods, such as brown sugar or spices. While vacuum packaging is not a substitute for traditional canning methods, it does keep food fresh three to five times longer than keeping it in a plastic food storage container in the refrigerator. --Cristina Vaamonde
This FoodSaver jar sealer allows vacuum packaging in wide mouth jars. It's ideal for liquids and fragile foods, or for storage of dry goods such as brown sugar, spices, dried fruit and flour.
