Effect of the temperature and duration of storage on quality characteristics of fresh-cut papaya fruit
Effects of storage temperatures (0 ± 2, 5 ± 2 and 10 ± 2 °C) and storage durations (1,2,3, 4 and 5 days) on the quality of fresh-cut papaya (Carica papaya Cv. Exotica II) were determined. Each stored fresh-cut papaya slices samples were compared with freshly cut papaya fruit slices (Control). The...

| Summary: | Effects of storage temperatures (0 ± 2, 5 ± 2 and 10 ± 2 °C) and storage durations (1,2,3,
4 and 5 days) on the quality of fresh-cut papaya (Carica papaya Cv. Exotica II) were
determined. Each stored fresh-cut papaya slices samples were compared with freshly cut
papaya fruit slices (Control). The visual appearance, weight loss, firmness, total soluble
solids, pH and total titratable acid were evaluated daily throughout the storage period.
Sensory evaluation based on difference-preference testing involving 20 panelists was also
carried out. Sweetness, texture, taste, aromatics, juiciness and overall acceptability was
determined using a defined hedonic score. Fresh-cut papaya slices stored at lower
temperatures (0 ±2 and 5f2 °C) showed better visual appearance, reduced weight loss
and high firmness. Storing fresh-cut papaya at 10 ± 2 °C was not suitable due to the poor
visual appearance that limits its marketability, excessive loss of water and dramatic loss
of firmness. There were no significant effects of storage temperatures on the total soluble
solids, pH and total titratable acid. However, the changes in these chemical properties
were significantly affected by storage durations. Sensory evaluation indicated that the
fresh-cut slices stored at 10 ±2 °C were preferable for consumption. The storage duration
did not significantly influence the changes in sensory qualities. |
