| Summary: | The current study aimed to establish the chemical constituents, enzymatic browning, and physicochemical and phytochemical attributes of Artocarpus odoratissimus flesh during post-harvest ripening. This study employed a randomised complete block design (RCBD) with storage methods (with and without packaging) and temperature conditions (ambient at 25 °C and chilled at 10 °C) as the variables. After eight days of storage at 25 °C, the pH of the unpackaged fruits (control) significantly increased from 6.65 ± 0.02 in treatment 1 (T1) to 6.91 ± 0.01 by the eighth day in treatment 5 (T5). The fruit samples stored at room temperature also exhibited improved browning (0.25 ± 0.02) and phenylalanine ammonia-lyase (PAL) (667.66 ± 2.21 UE g−1 min−1) and polyphenol oxidase (PPO) (527.00 ± 0.77 UE g−1 min−1) enzymatic activities, particularly during days four to eight, with pronounced effects observed in packaged fruits. Meanwhile, storage at 10 °C delayed browning, documenting 0.18 ± 0.01 on the fourth day to 0.13 ± 0.01 on the 16th day. Enzymatic activities were also reduced, extending their flesh shelf life. The findings suggested that storage at 10 °C (low temperature) effectively prolonged the freshness of Artocarpus odoratissimus flesh. The method could be a practical approach to mitigating browning and enhancing shelf life and marketability. |
