Tomato Flavor and Aroma Quality as Affected by Storage Temperature

ABSTRACT: Studies were conducted to describe flavor and aroma in ripe tomatoes stored at 5, 10, 12.5 and 20 °C. Fruit stored for 2 d below 20 °C were rated by trained sensory panelists as significantly lower (P < 0.05) in ripe aroma, tomato flavor, compared to those stored at 20 °C. Fruit stored at 5 °C for 4 d were rated significantly lower in ripe aroma, sweetness, tomato flavor, and significantly higher in sourness, compared to those stored at 20 °C. Following 8 and 12 d storage, fruit at 5 °C were rated lowest in ripe aroma and sweetness. Significant reductions in important GC aroma volatiles and chemical composition and electronic nose analyses concurred with sensory descriptor ratings.
