Abstract
A water-soluble prolamin composition, such as a zein composition, and methods for producing the same. A method for tagging items comprising applying a plurality of non-coding DNA tags in a prolamin composition, such as a zein composition, wherein the selection of the particular taggants corresponds with a binary or nonbinary code sequence containing information about the tagged items.
Claims20
A water-soluble composition comprising zein, cyclodextrin, surfactant, casein, and [1,3]-propanediol, in an aqueous carrier solution.
A method for tagging items comprising:
- mixing a plurality of non-coding DNA tags with a solution of zein and surfactant in [1,3]-propanediol, to provide a DNA-containing amorphous zein solution;
- combining the DNA-containing amorphous zein solution with cyclodextrin, and casein, to provide a zein mixture comprising the plurality of non-coding DNA tags, the cyclodextrin, the surfactant, and the casein;
- and
- applying the zein mixture to an item to create a tagged item, wherein a selection of particular tags corresponds with a binary or nonbinary code sequence containing information about the tagged item and wherein a non-coding DNA tag comprises a DNA sequence that would not otherwise be present in or on the tagged item.
