Abstract
Description
Abstract This invention provides an iron-free oxygen-removing composition. The composition comprises ascorbate palmitate, natural antioxidants, activated carbon, silica gel, 4A molecular sieve, and water. The natural antioxidants include lycopene, ginger, orange, and lemon powder. The ratio of ascorbate palmitate, lycopene powder, and other components (activated carbon, silica gel with a water activity between 0.47 and 0.60, and 4A molecular sieve) in the composition is maintained at 3.2:1.1:1.4. This iron-free oxygen-removing composition has enhanced oxygen removal capacity, simultaneously removing oxygen, moisture, and odors from packaging. This iron-free oxygen-removing composition is environmentally friendly and can extend the shelf life of pharmaceuticals, food, and nutritional supplements.
