Abstract Details

2018, Doctor of Philosophy, Ohio State University, Food Science and Technology.
Recent safety scares with imported products have raised significant concerns in the U.S. threating a 1.2 trillion dollar food industry, and to the billions of dollars of imported foods. Perpetrators and unscrupulous manufacturers are using their knowledge to beat the system by tricking regulatory agencies and supply chains with adulterated products costing the industry billions of dollars in revenue losses, recalling products, rebuilding their brand, restoring public health and reparations. Economically motivated adulteration (EMA) and contamination of global foods may cost the industry an estimated $10 to $15 billion per year. The aim of EMA is to inflate profits by fraudulent means and it is estimated that up to 10% of food products in retail stores contain some degree of adulteration. There have been multiple cases of EMA including the 2013 Groeb Farms, Inc. in which the US Department of Justice criminally charging them a $2 million fine for the illegal purchase of Chinese-origin honey. However, EMA can have serious consequences for public health. In 2008, milk and infant formula was adulterated with melamine costing $18 billion in fines, recalls and reparations and physical harm with 300,000 people becoming ill, more than 50,000 infant hospitalizations and six infant deaths. Analytical methods for determining whether a raw material is adulterated and for routine monitoring for quality assurance is expensive, time consuming and labor intensive. There is a need for sensitive and robust screening tools for assuring the quality of incoming raw materials to supplement the assurances provided by food manufacturer and vendor auditing programs. Our aim is to evaluate the ability of vibrational spectroscopy (mid-infrared (MIR), near-infrared (NIR) and Raman) in combination with multivariate analysis and supervised pattern recognition techniques as a screening tool for authentication and detection of contaminants in high priced food ingredients.
