Presentation will begin: Tuesday, April 18, 2023 - 1:50 PM EDT
Presented by: Luis Rodriguez-Saona, Ohio State University
The current methods for testing foods are time-consuming, expensive, labor-intensive, and require complex procedures for sample treatment along with well-trained technicians to operate expensive instrumentation. Vibrational spectroscopy (NIR, IR and Raman) technology provides rapid and cost-effective tools for effective food surveillance.
Rodriguez-Saona covers the current state of research for applications of vibrational spectroscopy for monitoring raw materials, screening for adulteration, and detecting food contaminants. Optical technology is rapidly developing into small size and compact devices allowing for robust, high-throughput, and ease of operation in-field routine analysis.
This technology addresses the industry need for tools that can verify nutritional levels at the point of sale. These tools allow the detection and quantification of food components through spectral signature profiles enabling real-time, field-based measurements to assist in controlling the product stream, addressing risk management, and brand equity.
About the presenter
Luis Rodriguez-Saona, Ph.D., is distinguished professor in the Department of Food Science and Technology at the Ohio State University (OSU). He received his bachelor’s and food engineer degrees from the Universidad Nacional Agraria, La Molina, in Lima, Peru. Later, he received his master’s and doctorate degrees in food science from Oregon State University in 1994 and 1998, respectively.
Rodriguez-Saona has worked as research scientist for the Joint Institute of Food Safety and Applied Nutrition (JIFSAN– UMD/FDA) and the U.S. Department of Agriculture Human Nutrition and Research Center before joining OSU. He is the undergraduate coordinator in his program and serves as undergraduate liaison with the college as well as being the contact for prospective students. Rodriguez-Saona advises over 80 students and is responsible for assisting in planning their course of study, minor, course selection, and career focus. He has received the OSU Outstanding Teacher Award, the OARDC Distinguished Faculty Research Award, and the North American Colleges and Teachers of Agriculture (NACTA) Educator Award.
His main area of research is the applications of spectroscopic techniques for chemical detection and characterization in the field of agricultural. Through collaboration with leading optical sensing industries, the Molecular Vibrational Lab has pioneered the application of portable and micro- devices combined with chemometrics for the screening of target components. His research has been nationally and internationally recognized for use in the integration of pattern recognition analysis of complex spectral information to identify the potential tampering of foods. Rodriguez-Saona’s work has generated over 110 peer-reviewed articles, 20 book chapters, and has been featured in multiple national and international meetings.
