Abstract

Trimmed Young Coconut or TYC is one of Indonesia's favorite tropical fruit. The high demand for TYC brings to the development of TYC preservation in Indonesia. However, due to its damage, postharvest handling that has not been optimally operated impedes the development of the TYC agroindustry. In addition, it can cause problems in the form of quality degradation such as the appearance of mold, decay, shell cracking, and browning of TYC. The solution to prevent damage and extend the shelf life of trimmed young coconut (TYC) is hot water blanching. In this study, the temperature that is used is 80 ℃ and 95 ℃. While the immersion time applied was 1.5 and 5 min was carried out to keep the TYC quality for long-term storage. This study used 12 TYCs produced by local coconut farmers. Then, the TYC was kept at cold storage which is set at a temperature of 17 ± 0.5 ℃ and RH 90%. Physiological changes parameters such as carbon dioxide (CO2) production and colour changes were analyzed every day for 6 days of storage. Statistical analysis was implemented to test the hot water blanching effect on TYC for each parameter. This study has a conclusion that TYC with 95 ℃ with 5 min of hot water blanching gives the best result in extending the shelf life of TYC.
