ABSTRACT:
An antioxidant composition which utilizes a desiccant carrier impregnated with a suitable fat soluble antioxidant is conveniently contained within a vapor permeable housing to prevent homogeneous mixing thereof with a stored product when the composition is provided in granulated form. The desiccant carrier is selected from a group of suitable hydrophilic materials which demonstrates the capacity for reducing levels of atmospheric moisture by absorption thereof, including for example, silica gel. The housing may conveniently be a sealed packet formed from a porous fiber material, such as, for example, that commonly used for fashioning tea bags and the like. Alternatively, the housing may include an enclosed perforated structure, the perforations of which are smaller than the granules of the contained composition. Where the composition is provided in the form of a unitary body, a housing need not be used. The antioxidant composition is prepared by impregnating the selected desiccant with an oil soluble antioxidant, which includes for example, such compounds as ethoxyquin, ascorbyl palmitate, stearate or oleate, propyl gallate and other gallate esters, BHA (butylated hydroxy anisole), BHT (butylated hydroxy toluene), tocopherols and salts thereof (either natural or synthetic), TBHQ (tertiary butyl hydro quinone), etc. The composition, when placed in a closed atmosphere with the stored product, absorbs any moisture present therein, and releases antioxidant in vaporized form into the ambient atmosphere, which then permeates throughout the stored product.
