Name two methods of sensory evaluation used in quality control.

• A. Visual inspection and sensory tasting by a trained panel
• B. Visual inspection and chemical analysis
• C. Thermal testing and weight measurement
• D. Cooking time and temperature control

Answer: (A)

Sensory evaluation relies on human perception to judge product quality, and the two common methods in quality control are visual assessment of appearance and tasting by a trained panel. Visual inspection focuses on what the product looks like—color, uniformity, surface defects, gloss, and packaging condition—because appearance often drives first impressions and can signal problems in sourcing or processing. Sensory tasting by a trained panel goes deeper into how the product smells, tastes, and feels in the mouth, using standardized scales to describe aroma, flavor intensity, texture, and aftertaste. This controlled, systematic tasting captures nuanced differences that instrumental tests may miss and helps ensure consistency across batches.

Other options aren’t sensory evaluation methods because they rely on measurements or physical properties rather than human perception of sensory attributes. Chemical analysis, for example, checks composition rather than how the product is perceived by a eater. Thermal testing and weight measurement assess physical performance, while cooking time and temperature control pertain to process parameters rather than sensory quality.
