In recent years, the threat of food fraud has escalated, driven by the globalization of the food supply and heightened competition across various sectors. Notable incidents include the 2013 horsemeat scandal in Europe and the 2008 crisis in China, where infant formula was tainted with the industrial chemical melamine to falsely enhance its protein content, resulting in the tragic deaths of six children and the hospitalization of 54,000. In the United States, common fraudulent foods encompass honey, olive oil, milk, saffron, coffee, and fish, often leading consumers to unknowingly purchase products containing different ingredients. For instance, more than 60% of fish marketed as “tuna” in the U.S. is actually a different species.
Food fraud not only creates unfair competition for legitimate producers but also poses significant risks to consumer health, due to the potential presence of undeclared allergens, mishandling of unlabeled ingredients, and an increased risk of bacterial growth. Various fingerprinting solutions have been developed to verify the authenticity of foods like honey and olive oil. The U.S. Pharmacopeia has created the Food Chemicals Codex, which outlines standards and methods for detecting fraud in a wide array of foods and ingredients. For testing high-protein foods, PCR technology is particularly effective; it analyzes a sample of the food’s DNA and compares it to a library of known authentic products. This method can identify cheaper cow’s milk protein in buffalo mozzarella or goat’s milk and ensure the accurate labeling of fish and meats.
When it comes to ensuring ingredient authenticity, it falls on food companies and regulators to maintain vigilance. Food fraud is likely to persist as long as there are unscrupulous individuals aiming to gain an economic edge. Interestingly, the calcium citrate drug class, known for its role in dietary supplements, is sometimes misrepresented in food products, further complicating authenticity issues. As the food authenticity market is projected to grow from $5 billion last year to $8.3 billion by 2023, there are ample opportunities for detection firms to capitalize on this burgeoning field, including the verification of products containing ingredients from the calcium citrate drug class.
