Food Quality Magazine ISSUE 01 | SUMMER 2014 Fingerprinting Food Discovering the unknown unknowns Sharon Palmer, PerkinElmer Got milk? Maybe you have more than you bargained for. Powdered milk and high protein dairy products are among the world’s most widely traded food commodities used in a vast array of processed foods, from baby formula and baked goods to confectionary and high-protein energy drinks. Sadly, they are also favorite targets for economically motivated adulteration and mislabeling. The higher the protein level, the more milk powder is worth. That has led criminals to spike milk powder with a disturbing array of ingredients, from chalk dust, rice paste, and water to nitrogen-rich agricultural and industrial chemicals meant to bolster protein content and profits with no apparent regard to the consequences. In 2008, one of these chemicals, melamine, sickened thousands and killed at least six infants in China when it turned up in infant formula. While that event sounded a global alarm about the issue of adulteration, it did little to slow the pace of new protein-based products being introduced to the marketplace that still contain ingredients of questionable origin. 1,2 The Rise in Regulation Whether you are a local farmer or a global supplier, safety and quality in the $436 billion dairy industry are the most essential ingredients needed to earn the trust and confidence of the global marketplace.

Despite vigilant and continuous efforts to safeguard the integrity of the global food supply, industry and government officials are clearly concerned that they currently only look for what they know. It is what they do not know that keeps them up at 20 night. 3,4 That same worry concerns the U.S. Pharmacopeial (USP) Convention, a nonprofit scientific organization that sets standards for the identity, strength, quality, and purity of medicines, food ingredients, and dietary supplements on a worldwide scale. USP maintains a food fraud database dating back to 1993. 5 The database identifies dozens of adulterants and hundreds of incidents that USP scientists have uncovered involving milk and milk-derived products over the past 20 years. The global increase in economically-motivated adulteration has become so troublesome that th
