  5. Untrained Panelists • Evaluate after a product is developed. • Highly variable and inconsistent so needs large numbers of panelists. A 1.02 -- Taste Panels

  6. Control influence from other panelists Isolated booths One person at a time to test Limited noise Control environment Colored lights. if possible Blindfolds Warm water for rinsing between samples All samples the same temperature Control psychological bias Use codes to identify samples (letters and numbers) Use 3-digit numbers Maximum 4 to 5 samples Taste same samples in different orders Setting Up A Taste Panel A 1.02 -- Taste Panels
