Developing a Descriptive Sensory Characterization of Flour Tortilla Applying Flash Profile

Area of Science:

• Food Science
• Sensory Analysis
• Consumer Behavior

Background:

• Understanding consumer food preferences and consumption patterns is crucial for product development.
• Descriptive methodologies are essential for identifying product quality attributes.
• The flash profile (FP) method offers a rapid approach to attribute generation without extensive panelist training.

Purpose of the Study:

• To investigate the consumption and preference of flour tortillas among consumers.
• To develop a descriptive characterization of flour tortillas using the flash profile method.

Main Methods:

• Utilized the flash profile (FP) method with ten experienced panelists.
• Generated 22 distinct sensory descriptors (texture, appearance, odor, flavor) for flour tortilla samples.
• Applied Generalized Procrustes Analysis to analyze sensory data and assess panelist performance (Rc = 0.508).

Main Results:

• The flash profile (FP) method successfully generated descriptors that differentiated between commercial and handcrafted flour tortilla samples.
• The first two dimensions of the Generalized Procrustes Analysis explained 83.78% of the data variability.
• Panelist performance was validated with a consensus index (Rc) of 0.508.

Conclusions:

• The flash profile (FP) method is an effective, rapid, and accessible technique for obtaining distinctive sensory attributes of food products like flour tortillas.
• This method aids in understanding product characteristics important for consumer preference and quality assessment.
