Sealing in nutrition—and taste. There are proven nutritional
benefits to storing foods using the Seal-a-Meal® System instead
of conventional storage methods. Oxygen causes oxidation, a
process which causes the breakdown of natural vitamins and other
nutrients in food, decreasing its nutritional value. The Seal-a-
Meal® Vacuum Food Storage System removes the oxygen—so the
nutrients in foods are preserved. There's a science to
preserving flavor, too. Flavor is affected dramatically by
storage conditions, and our senses are able to detect some
changes in food in a matter of days. Fatty foods are
particularly prone to developing "off" flavors. The Seal-a-Meal®
System not only removes the oxygen that causes flavor
degradation, but keeps nearby flavors out, so food tastes
fresher, longer.
