The role of sensory evaluation

Prof. Susan Duncan is a professor in Food Science & Technology at Virginia Tech. She focuses on the role of flavor, sensory quality, and nutrient value of food. With the help of FaceReader, she can capture how people are interacting with and responding emotionally to food products.

How do we experience food consumption?

In response to seeing, smelling or tasting food, facial expressions demonstrate how we react to the particular food. Maybe it smells disgusting, does the weird color makes us feel anxious, or does the experience of the tasty food gives us a happy feeling. Often, these are ‘in-the-moment-responses’ which we are not aware of. FaceReader can help study these unconscious consumer responses.


Prof. Susan Duncan: "We have the privilege of using Noldus software in our laboratory."

In this video, Prof. Susan Duncan of Virginia Tech explains that FaceReader augments the traditional sensory evaluation technologies and allows them to try and explore new things. To be able to use machine learning for capturing how people respond to products is amazing. 

Watch the video to learn more about why she chooses Noldus' tools.
