Kajian Disinfestasi Lalat Buah (Bactrocera dorsalis) dengan Perlakuan Uap Panas (Vapor Heat Treatment) pada Mangga Gedong Gincu
Abstract: Since the
prohibition of chemical method for insect disinfestations processes such as
ethylene dibromide in 1984, heat treatment method was developed as quarantine
technology. One of the heat treatment methods is vapor heat treatment (VHT).
The objectives of this research were to study mortality of fruit fly
(Bactrocera dorsalis) and to study the responses of VHT on quality of gedong
gincu mango. Fruit fly mortality due to heat has been investigated by immersing
fruit fly eggs into heated water at temperatures of 40, 43, 46 and 49OC for 30
minutes immersed, also at temperature of 46OC for 5, 10, 15, 20, 25 and 30
minutes. Gedong gincu mangoes were treated at temperature 46.5OC for 0, 10, 20,
and 30 minutes. The results showed that mortality has been achieved 100% at
temperature more than and equal to 43OC for 30 minutes and at temperature 46OC
for more than and equal to 10 minutes. The VHT has significantly and fungi
population although without adversely affecting to the fruit quality and there
were no significant change in the fruitweight loss, hardness, color, soluble
solid content, water content, vitamin C and organoleptic test. VHT at temperature
46.5OC for 20 up to 30 minutes were effective to kill fruit flies inside
mangoes and were able to maintaining mango quality during storage.
