Rapid Food Authentication Using a Portable Laser-Induced Breakdown Spectroscopy System
January 14, 2023
Laser-induced breakdown spectroscopy (LIBS) is an atomic-emission spectroscopy technique that employs a focused laser beam to produce microplasma. Although LIBS was designed for applications in the field of materials science, it has lately been proposed as a method for the compositional analysis of agricultural goods. We deployed commercial handheld LIBS equipment to illustrate the performance of this promising optical technology in the context of food authentication, as the growing incidence of food fraud necessitates the development of novel portable methods for detection. We focused on regional agricultural commodities such as European Alpine-style cheeses, coffee, spices, balsamic vinegar, and vanilla extracts. Liquid examples, including seven balsamic vinegar products and six representatives of vanilla extract, were measured on a nitrocellulose membrane. No sample preparation was required for solid foods, which consisted of seven brands of coffee beans, sixteen varieties of Alpine-style cheeses, and eight different spices. The pre-processed and standardized LIBS spectra were used to train and test the elastic net-regularized multinomial classifier. The performance of the portable and benchtop LIBS systems was compared and described. The results indicate that field-deployable, portable LIBS devices provide a robust, accurate, and simple-to-use platform for agricultural product verification that requires minimal sample preparation, if any.

Susan McCreery recipient of the Above and Beyond Award at the 2022 OEVPRP Employee Recognition Award
December 16, 2022
The Above and Beyond Award program is the Office of the EVPRP adaptation of the university?wide Bravo Award. It is an after?the?fact discretionary award program designed to provide recognition and reward for substantial accomplishments that extend well beyond regular work responsibilities. This award differs from the annual Merit Awards (which recognize outstanding job performances) as the Above and Beyond awardees are recognized for extraordinary contributions that have made a positive impact on their department, Purdue, and/or the community.

Impact of combination of short lecture and group discussion on the learning of physiology by nonmajor undergraduates
December 15, 2022
The purpose of this study was to evaluate the effect of group discussion on the learning of mammalian physiology by nonmajor undergraduate students. Combining traditional lectures with group discussions increased the active participation of students in class and improved their learning of physiology, as measured by the results of in-semester and final examinations. The active learning technique benefited all class ranks on average. Purdue University Elikplimi K.
