About the Presentation

 

Sensory analysis is performed in FDA testing laboratories to determine the decomposition status of seafood samples. Current methodology to complement this testing with chemical analysis (e.g., histamine) is not always directly comparable to sensory testing. 

The presentation will discuss a new method that FDA is exploring with untargeted analysis and a statistical model driven by sensory results via a script written in the R programming language. This makes it possible to generate data that are directly comparable to commonly used sensory scoring techniques. 

Over time this work has the potential to inform FDA’s decision-making process by making an additional screening tool available to laboratories that do not have sensory capability, or even to remote field locations
