The present study investigated the relationship between physical conditions and sensory properties of red pepper powder stored at different temperatures (-20 o C, 0 o C, 20 o C) and in different wrap materials (linear low density polyethylene, LLDPE; aluminum/linear low density polyethylene, Al/LLDPE). Red pepper powders with initial moisture contents of 17.35±0.32% were not affected by the packaging material or storage temperature. Hunter a values of red pepper powder decreased while Hunter b

The American Spice Trade Association (ASTA) color value (60.85±0.13) significantly decreased with increasing temperature from -20 o C to 20 o C (21.70 ±0.06 to 56.03±0.24). The ASTA color value of samples packed with LLDPE (21.70±0.06) decreased more compared to samples packed with other materials. Further, capsanthin contents (13.74±0.02 mg/100 g) significantly decreased with increasing temperature from -20°C (0.25±0.01 to 0.28±0.01 mg/100 g) to 20 o C (0.13± 0.01 to 0.25±0.01 mg/100 g). In the sensory evaluation of red pepper powder, overall acceptability was influenced by redness, yellowness, and pungency color. All physicochemical and sensory properties of red pepper powder were compared. Hunter a values, ASTA color values, and capsanthin contents were significantly associated with sensory preferences. In particular, ASTA color value showed a close relationship with color preference for red pepper (R2=0.922). Thus, we suggest that the preference for red pepper powder can be determined based on instrumental measurements of Hunter a values, ASTA color values, and capsanthin contents.
