초록

This study investigated the correlation between physicochemical (color, soluble solids content (SSC), pH, titratable acidity (TA), and firmness) and sensory (appearance, taste, odor, and texture) characteristics of environment-friendly ‘Campbell early’ grapes to identify quality indices. For analysis, samples of similar-sized grapes were collected from five orchards. The results showed that the physicochemical characteristics of CIE L*, CIE a*/b*, SSC, pH, TA, and firmness and the sensorial characteristics of color intensity, freshness of stem, odor, sourness, sweetness, and elasticity were different among groups. Correlation analysis results showed that an increase in sweetness and firmness and a decrease in sourness were associated with an increase in overall acceptance. Sourness and sweetness were positively correlated with CIE L* (r=0.88) and firmness (r=0.95), individually. In the principal component analysis results, component F1 and F2 explained 44.35% and 33.77%, respectively, of the total variance (78.12%). F1 represented firmness, sweetness, elasticity, hardness, grape odor, color intensity, sweet odor, sourness, and damage degree. F2 represented CIE L*, TA, CIE a*, CIE a*/b*, SSC/TA, SSC, and peel thickness. The results showed that consumer acceptance of ‘Campbell early’ grapes can be determined by assessing physicochemical attributes of firmness, CIE L*, TA, CIE a*, CIE a*/b*, SSC/TA, and SSC and various sensorial attributes including sweetness, fruit elasticity, fruit hardness, grape odor, and color intensity.
