Menunda kerusakan buah sawo (Manilkara zapota (L.) van Royen) dengan berbagai lama penyinaran UV-C dan penyimpanan pada suhu rendah
Abstract: Sapodilla (Manilkara
zapota (L.) van Royen) is a perishable fruit that exhibits rapid deterioration
after harvesting. Low temperature storage has been extensively used to extend
the storage life of many fresh commodities, however it is still rarely used for
sapodilla. UV-C radiation has been studied for its capability to inhibit fruit
ripening and senescence, and hence prolonging the period of fruit salability.
This UV-C radiation might be a pre treatment for sapodilla before storage at
low temperature. The objective of this research was to extend the storage life
of sapodilla fruits by retarding ripening process through UV-C radiation and
low temperature storage. Sapodilla fruits were exposed to four levels of UV-C
exposure time i.e. 0 (no radiation), 5, 10, and 15 minutes, then stored at room
temperature (27,13–28,11oC) and low temperature (16,70–18,13oC). Observations
were taken on fruit respiration and ripening, and other related variables. The
results showed that there was no interaction between UV-C radiation and storage
temperature. The UV-C radiation did not significantly inhibit fruit ripening,
thus did not inhibit the fruit senescence and deterioration. Keeping the fruit
at low temperature inhibit fruit ripening and prolong its shelf life 6 days longer
than those stored at room temperature.
Key words: Sapodilla, UV-C
radiation, low temperature storage, ripening, deterioration
