| Popis: | Precooling showed promises treatment for chilling injury symptom in the fruit. The research aimed to determine the effect of pre-cooling dan coating treatment using chitosan to the internal browning symptoms of pineapples during cold storage at 10°C. The pineapples of cultivar “Smooth Cayenne” were treated with 6 treatments, namely P0C0 (no pre-cooling and no chitosan), P0C1 (no pre-cooling and chitosan), P1C0 (1-day pre-cooling and no chitosan), P1C1 (1-day pre-cooling and chitosan), P2C0 (3-day pre-cooling and no chitosan), P2C1 (3-day pre-cooling and chitosan). Fruits qualities were evaluated by their weight loss, firmness, chilling injury, and chemical compounds including titratable acidity, phenol compounds, and reducing sugar. The analyses were performed on day 7, 14, 21, 28, and 28+3 days of storage. Each treatment was replicated three times and the data was analyzed using factorial complete randomized design (CRD). The result showed that pre-cooling and chitosan was able to inhibit chilling injury and prolong the shelf life of “Smooth Cayenne” pineapple. |
