Consumers around the world are increasingly demanding information on and reassurance of the origin and content of their food. In addition, food manufacturers must provide and confirm the authenticity and point of origin of food products and their components. These increased demands come amid legislative and regulatory pushes that increase the complexity and level of regulation imposed on the food supply worldwide. Protecting consumer rights and preventing fraudulent or deceptive practices such as food adulteration are important and challenging issues facing the food industry.

Food adulteration reports are a growing challenge for food manufacturers. Because most adulterants are unknown, they are difficult to recognize using the targeted screening methods typically used in food laboratories. The industry urgently needs methods that will screen non-targeted food samples for contaminants to provide proof of origin and prevent deliberate or accidental undeclared admixture to food samples.
Determining the authenticity of foods can prevent false description, substitution of cheaper ingredients, and adulteration, as well as incorrect origin labeling. This article will provide an overview of food authentication challenges and will highlight the need for rapid development of analytical methods to enable reliable food authentication.
Food Authentication Challenges
Consumers and producers alike place a high value on accurate and defensible labeling, and providers are now proactively providing consumers with clear labeling, traceability, and transparency. These producers must convert ingredients received from around the world into a finished product that is then distributed globally. The challenge for food producers lies in complying with international, national, and local traceability rules that apply both to what comes in and what goes out.
The growing variety and complexity of available foods is one challenge within the food industry. Consumers demand information about, and proof of, the quality and safety of “new” food items and preservatives. Meanwhile, rapid population growth results in raw material shortages, which in turn forces some producers to bulk up their products with questionable fillers, a strategy that, in itself, introduces additional ingredients of unknown origin.
Regulators worldwide must develop standards and legal policies to determine ways to identify and label food using appropriate terminology. Regulatory agencies now require food testing laboratories to meet lower detection levels for potential contaminants and continually add compounds and matrices to those that must be analyzed. Keeping contaminants out of the food chain requires robust instrumentation that can meet today’s threats while being advanced enough to address tomorrow’s challenges.
