| 概要 |
Lanzones (Lansium domesticum Correa) is a highly perishable tropical fruit. This study evaluated the effects of polyethylene (PE) packaging (25, 36, and 64 μm thick) and storage temperature (13, 18, a...nd 31 °C) on fruit quality and shelf life. Key quality properties: Weight loss, color (L^*, a^*, b^*), browning index, and total soluble solids (TSS). The degradation patterns of these parameters were modeled using zero- and first-order reaction kinetics, and temperature dependence was analyzed using the Arrhenius equation. Weight loss followed zero-order kinetics, while color and browning index followed first-order kinetics. The browning index was the most effective shelf life indicator. First-order kinetic models based on the browning index accurately predicted shelf life, with relative errors of less than 12%. Polyethylene bags of 36 μm and 64 μm stored at 13 °C best preserved the fruit quality. These results highlight the critical role of packaging and temperature in optimizing the postharvest handling and marketability of lanzones.続きを見る
