Pengkajian Karakteristik dan Pendugaan Umur Simpan Jambu Mete Segar (Anacardium occidentale L.) pada Sistem Penyimpanan Atmosfir Termodifikasi

Abstract

The aims of this research are: I) to identify the changes of physiologic characteristics of cashew apples during storage under MAP system; 2) to verify the changes of their quality during storage; and 3) to establish the optimum gaseous compotition range in the MAS system. To completed the research, the experiment was conducted by four steps activities as follows: I) the measurement of respiration rate; 2) establishment of the range of modified atmosphere storage for cashew uppels; 3) computing the packaging area and selecting the kind of plastic film; 4) prediction of shelf life for cashew appels during storage under MAP system. The results showed that the O2 consumption rates of cashew appels were 9.21, 14.82, 18.02, 25.50, 5 1.35 (ml/kg-h) and the C02 production rates were 13.99, 24.79, 32.33, 46 88, 75.42 (&kg-h) for temperature storage of 5, 10, 15, 20 and 26.7 "C, respectively. The gaseous composition of 4 - 6 % O2 and 5 - 9 % C02 and propilene film was the best for protection of the cashew appels quality during storage, with the packaging area and weight of cashew appels for modified atmosphere storage design were 0.0240 m2 and 119.59 g, respectively. Under above condition, the shelf life of cashew appels was 17.95 days in the 10 "C temperature storage and 18.97 days in the 5 "C temperature storage by using MAS system.
