This study was done to preserve snake fruit cultivar Pondoh cold temperature storage. Snake fruits was obtained from Turi, Sleman, Yogyakarta and transferred to the laboratory with the aseptic condition. The sortation based on the visual method was used to collect the proper snake fruit. The cleaning using aseptic cloth was done prior to storage. The snake fruit was collected individually in refrigeration containers at temperatures of 10±5˚C. The storage was done for 30 days and it was stopped until appearance of physical damage in snake fruit. The result indicates that the storage using this method might extend the shelf-life of snake fruit until 28 days. However, snake fruit was hardly to peeled and dry. It can be concluded that cold temperature might extend the shelf-life of snake fruit.

This study was carried out to assess the morphological characteristics, fruit quality, and antioxidant levels in sucrose ester-coated ‘Harmony’ plumcots (Prunus salicina Lindl. × P. armeniaca L.). Fruit samples in the control group were left untreated, with two further groups undergoing coating either after 0 days of cold storage (0 d CS) or after 7 days of cold storage (7 d CS) to evaluate changes in post-harvest quality at three-day intervals throughout 12 days of room temperature storage (12 DAS). Coating treatment significantly reduced fruit respiration during storage time in the 0 d CS samples, with this being attributed to the clogging of pores in peel stomata and lenticel, as observed on the fruits under scanning electron microscopy; however, the same effect was not observed in the 7 d CS samples from fruits with a high initial CO2 concentration. The coating delayed fruit softening and discoloration during storage in the 0 d CS samples, extending the shelf-life of the fruits for approximately 9 days. However, the coating treatment was found to reduce total flavonoid and anthocyanin content at 6 DAS and 12 DAS in both groups.

Sweet corn has short shelf life at room temperature storage in the tropical countries (28-33°C). The quality deterioration of sweet corn can be determined by the decrease of its sugar content. The study aimed to estimate the shelf life of sweet corn based on the reduction of its total soluble solid (TSS) by using Arrhenius model. The samples were prepared from fresh harvested corn stored for 10 days at 3 different temperatures of 5, 15 and 28 °C. Total soluble solid (TSS) were analyzed every day by using abbe refractrometer. Organoleptic analysis was used by using hedonic scales from 1 to 7. The analysis was conducted until respondents had graded the samples at score 5 (dislike slightly), 6 (dislike) and approaches can be used to calculate the shelf life of sweet corn. The acceleration factor for the TSS degradation at null approach, it was estimated that if the sweet corn were stored at temperature of 30, 25, 20, 15, 10 and 5°C, the shelf temperatures, the shelf life of sweet corn would be 3.7, 4.5, 5.6, 6.8, 8.4, and 10.3 days. In conclusion, the shelf life predictions of sweet corn were valid well with the experimental results.

Kerusakan jagung manis dapat diindikasikan dengan penurunan kandungan gulanya. Penelitian ini bertujuan untuk menduga umur simpan jagung manis berdasarkan reaksi penurunan kandungan total padatan terlarutnya (TPT) dengan pendekatan model Arrhenius. Jagung manis segar yang baru siap panen segera disimpan selama 10 hari pada 3 kombinasi suhu yaitu 5, 15 dan 28°C. Setiap hari dilakukan analisis kandungan TPT dengan . Uji organoleptik dilakukan dengan skala hedonik 1-7. Proses pengamatan dihentikan apabila responden telah memberikan nilai 5 (agak tidak suka), 6 (tidak suka) dan 7 (sangat tidak suka). Pendekatan model Arrhenius dilakukan dengan dua persamaan yaitu persamaan orde 0 dan orde 1. Hasil analisis menunjukkan bahwa kedua persamaan tersebut dapat dipergunakan untuk menduga umur simpan jagung. Nilai faktor percepatan reaksi penurunan mutu (Q) untuk persamaan orde 0 adalah 1,49, sedangkan nilai Q10 untuk persamaan orde 1 adalah 1,51. Dengan menggunakan pendekatan orde 0, penyimpanan jagung manis pada suhu 30, 25, 20,15, 10 dan 5°C akan berpengaruh kepada umur simpan jagung manis menjadi 3,7, 4,5, 5,5, 6,7, 8,2, dan 10 hari. Sedangkan dengan pendekatan orde 1, penyimpanan jagung manis pada suhu yang sama akan berpengaruh kepada umur simpan jagung manis menjadi 3,7, 4,5, 5,6, 6,8, 8,4, dan 10,3 hari. Dapat ditarik kesimpulan bahwa hasil dugaan tersebut sangat valid dengan hasil observasi.Kata kunci: Jagung manis, umur simpan, total padatan terlarut
