A Timely Application-Temporal methods, past, present, and future

Area of Science:

• Food Science
• Sensory Science
• Consumer Research

Background:

• Eating is a dynamic process, necessitating methods to capture product changes during consumption.
• Temporal sensory methods are crucial for documenting how food characteristics evolve over time.

Purpose of the Study:

• To review the evolution and current state of temporal sensory methodologies.
• To provide guidance on selecting appropriate temporal methods for food product evaluation.
• To offer insights into future research directions in temporal sensory analysis.

Main Methods:

• Comprehensive literature review of approximately 170 sources on temporal evaluation of food products.
• Analysis of various temporal methods, including Time-Intensity, Temporal Dominance of Sensations, and Temporal Check-All-That-Apply.
• Consideration of panelist selection and research scope in method selection.

Main Results:

• Temporal methods have evolved to capture diverse sensory attributes over time.
• Guidance is provided for selecting methods based on research objectives.
• The importance of panelist selection in temporal evaluations is highlighted.

Conclusions:

• Temporal sensory methods are essential for understanding the dynamic nature of food consumption.
• Careful selection of methods and panelists is critical for effective temporal sensory research.
• Future research should focus on validating and improving temporal methodologies.
