Usage Tips

  1. Preservative (E 224) is commonly added to wine or must (freshly crushed fruit juice (usually grape juice) that contains the skins, seeds, and stems of the fruit) in which it forms sulfur dioxide gas (SO2). This helps prevent micro-organisms from growing, and also it acts as an antioxidant, protecting both the color and delicate flavors of wine.
  2. It preserves the taste of dehydrated foods and makes these foods more palatable. It preserves frozen vegetables, frozen shellfish, fruit juice, and pickles and increases their shelf-life.
  3. Always store Preservative (E 224) in a cool and dry place, away from direct sunlight and keep in a tightly sealed container when not in use.
