title: Effects of debittering on grapefruit juice acceptance.
abstract: This study was conducted to assess the acceptance of grapefruit juice which has undergone a debittering process. The sensory effect of debittering and the sensory attributes of sourness, sweetness, bitterness, and aftertaste were appraised, and the correlation between chemical and sensory analyses of the debittered juice were identified. The effect of added grapefruit flavor on perception of sweetness and sourness was statistically significant. Both the level of bitterness and storage duration of grapefruit were shown to influence the way judges perceived bitterness and sweetness. Storage study showed no difference in aftertaste, which may increase consumers buying interest in debittered juice with a high level of bitterness (450 ppm).
