Abstract
Highly efficient, low cost, methods and compounds to determine product authenticity, tampering, manufacturing compliance are provided. The methods and chemicals defined are capable of measuring the relative amount of key materials in these products. The compounds are light emitting and interact with key elements in products like, neutral spirits, vodka, tequila, soft drinks and infant formulas. After the interactions are complete, methods are employed to determine resulting key components by light emission.
