Measuring Oral Fatty Acid Thresholds, Fat Perception, Fatty Food Liking, and Papillae Density in Humans

DOI: 10.3791/51236-v
What you'll learn
  • ✓ Prepare standardized fatty acid samples for human oral chemoreception testing
  • ✓ Conduct oral fatty acid threshold detection assays with human participants
  • ✓ Analyze taste detection thresholds and interpret individual variation in fat perception
  • ✓ Assess the relationship between oral fat sensitivity and dietary preferences
Protocol

Oral chemoreception of fatty acids and the association with diet and fatty food preferences may enable the identification of mechanisms involved with the development of obesity and why dietary changes may be difficult for many individuals.

Difficulty
intermediate
Total time
~1-2 hours per participant (including sample preparation, threshold testing, and sensory assessment)

Steps

1
Produce oral fatty acid threshold test samples

Prepare standardized fatty acid solutions at varying concentrations for threshold detection testing. Samples are formulated to assess individual sensitivity to fat chemoreception.

2
Conduct oral fatty acid threshold testing procedure

Administer fatty acid samples to participants in ascending concentration order to identify individual detection thresholds. Record responses and sensory perceptions at each concentration level.

3
Analyze taste detection thresholds and results

Quantify detection thresholds from participant responses and evaluate variation in individual fat perception sensitivity across the cohort.
