SENSORY EVALUATIONS ON TANGERINE‐GRAPEFRUIT JUICE BLENDS

Abstract
Tests were conducted on blends of tangerine and grapefruit juices reconstituted from concentrates. Flavor thresholds, preferences and influences of ∘Brix and ∘Brix/acid ratio on tangerine‐grapefruit juice blends were established from evaluations by panelists who were familiar with citrus juices. Flavor thresholds of tangerine in grapefruit juice were 14–15%. Blends at concentrations of 15–35% differed significantly from and were preferred over unblended grapefruit juice. Increasing ∘Brix of the blends caused a significant difference among blends, but the influence of ∘Brix/acid ratio was negligible.
