Food fraud is a rising concern in the food industry. The deliberate substitution, addition, tampering, or misrepresentation of food for financial gain defines food fraud. The Grocery Manufacturers Association estimates loss between $10 to $15 billion to food fraud each year. As the food supply chain becomes more complex and global, the possibility of encountering food fraud along the chain increases. Unfortunately, detecting and tracing cases of food fraud to the root sources becomes tougher.
