UPCOMING WEBINAR

Forensic and Unique Methods:
The Missing Piece to the Most Puzzling of Cases

Wednesday, January 21, 2026 | 11 AM - 12 PM CST

The production and distribution of foods, beverages, nutraceuticals, and related products can offer a wide variety of unique challenges at every stage of development and release. Off-odors and off-flavors, discolorations, and the presence of foreign materials are just some examples of unexpected issues that can arise causing unwanted delays in product release or negatively impact consumer perceptions of a product already on the market.

This webinar will cover various analytical strategies for troubleshooting these challenging problems, from project design and execution to data analysis, alongside real-world case studies to demonstrate the process in action.
