Summary
Remote sensory testing offers a valid alternative to traditional lab evaluations, maintaining data integrity outside the facility. This method, especially with trained panels and consumers, proved effective even during the pandemic.
Area of Science:
- Sensory Science
- Consumer Behavior
- Food Science
Background:
- COVID-19 pandemic restrictions impacted traditional sensory and consumer testing.
- A growing need for out-of-laboratory data collection emerged.
- Remote sensory testing offers a balance between control and convenience.
Purpose of the Study:
- To evaluate the effectiveness and validity of remote sensory testing.
- To compare remote testing results with classical laboratory settings.
- To develop guidelines for remote sensory evaluation sessions.
Main Methods:
- The Italian Sensory Science Society conducted a research project comparing remote and lab-based sensory tests.
- Methods included triangle, tetrad, Descriptive Analysis, Temporal Dominance of Sensations, Check-All-That-Apply, and hedonic tests.
- Tests involved both trained panels and consumers under live online supervision.
Main Results:
- Remote sensory testing yielded results comparable to lab testing across most methods.
- An exception was noted for the tetrad test conducted in a work environment.
- No significant differences were observed for triangle, Descriptive Analysis, Temporal Dominance of Sensations, Check-All-That-Apply, and hedonic tests.
Conclusions:
- Remote sensory testing is a viable and promising alternative to traditional laboratory evaluations.
- Strict adherence to specific sensory protocols is crucial for successful remote testing.
- This approach is applicable to both trained assessors and consumers, extending beyond pandemic-related needs.
