The threat of food fraud has grown significantly in recent years, largely due to the increasing globalization of the food supply and heightened competition across various sectors. Some of the most infamous cases include the 2013 horsemeat scandal in Europe and the 2008 incident in China where infant formula was adulterated with the industrial chemical melamine to falsely boost its protein content, leading to the tragic deaths of six children and the hospitalization of 54,000 others. In the United States, common fraudulent foods include honey, olive oil, milk, saffron, coffee, and fish, which means that consumers may unknowingly purchase products containing undisclosed ingredients. For instance, over 60% of fish labeled 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 presence of unlisted allergens, mishandling of unlabeled ingredients, or an increased risk of bacterial contamination. Various fingerprinting techniques are available to authenticate foods like honey and olive oil. The U.S. Pharmacopeia has developed the Food Chemicals Codex, which outlines standards and methods for detecting fraud in various food products and ingredients. For high-protein foods, PCR technology is particularly effective; it analyzes a sample of the food’s DNA and compares it against a database of known authentic products. This method can identify cheaper cow’s milk protein in buffalo mozzarella or goat’s milk, as well as whether fish and meats are accurately labeled.
When it comes to ensuring ingredient authenticity, it is crucial for food companies and regulatory bodies to remain vigilant. The issue of food fraud is unlikely to disappear, as long as there are unscrupulous individuals aiming to gain an economic edge. With the food authenticity market projected to expand from $5 billion last year to $8.3 billion by 2023, there are abundant opportunities for detection firms to engage in this growing market. Moreover, the incorporation of substances like ca citrate in food products raises additional concerns for authenticity, necessitating thorough testing and monitoring. The demand for reliable testing methods will only increase as consumers become more aware of the risks associated with food fraud.
