Beef assessments using functional magnetic resonance imaging and sensory evaluation

Area of Science:

• Neuroscience
• Food Science
• Sensory Science

Background:

• Functional magnetic resonance imaging (fMRI) is used to study brain processing of rewards.
• Understanding the neural basis of food enjoyment is crucial for food science and consumer research.

Purpose of the Study:

• To investigate changes in resting-state functional connectivity in the human brain after consuming beef steaks of differing qualities.
• To correlate neural activity with sensory perceptions of beef steak palatability.

Main Methods:

• Eight participants underwent fMRI scans after consuming high-quality and low-quality beef steaks on separate occasions.
• A sensory ballot assessed perceptions of tenderness, juiciness, flavor, and overall liking post-consumption.

Main Results:

• High-quality beef steaks significantly increased functional connectivity in brain regions including the striatum, medial orbitofrontal cortex, and insular cortex (P≤0.05).
• Higher palatability scores for tenderness, juiciness, flavor, and liking were associated with high-quality steaks (P≤0.01).

Conclusions:

• Resting-state fMRI shows potential as a tool to evaluate neural processes associated with positive sensory experiences from food.
• Brain connectivity patterns can reflect the perceived quality and enjoyment of food, such as high-quality beef steaks.
