With traditional blenders, as soon as you begin to chop, puree, and blend up fruits and vegetables, those nutrients are exposed to oxygen and begin to break down and lose their nutritional value. This continues if your blend is not enjoyed right away, or if it is placed in the refrigerator overnight. With vacuum blending, you are able to remove oxygen and preserve the nutrients in fruits and vegetables, even if you choose to enjoy your blended drink or smoothie the next day.
