Temporal Dominance of Sensations (TDS): a new deal for temporal sensory analysis

- TDS derives a temporal sensory profile as a sequence of perceived attributes.
- Temporal profile can be within one intake (sip, mouthful) or across consumption of the food portion.
- TDS is feasible by consumers with very light training.
- TDS can be paired with temporal liking allowing to derive temporal drivers of liking.
- TDS can be extended to wanting, satiation and emotion.

Temporal Dominance of Sensations (TDS) fills the gap between static multidimensional sensory profiling and dynamic unidimensional Time-intensity (TI) by offering a way to assess simultaneously several attributes dynamically over time. The breakthrough idea of TDS was to no longer score intensities, but to elicit dominances; a much simpler task feasible by untrained consumers. Consequently, TDS was recently paired with liking, wanting and/or satiation evaluated quantitatively and dynamically during the intake of a full portion of a food, beverage or combination of the two. Further, Temporal Dominance of Emotions (TDE) has been recently proposed as a TDS based on emotional rather than sensory attributes. TDS has truly rejuvenated research in temporal sensory evaluation to the benefit of food and beverage industries, which are currently using it extensively.
