Abstract
Nowaday, Philippines facing the major problem in agriculture sector, which is the post-harvest lost due to short shelf life of perishable crops. This study aimed to determine the influence of acoustic waves on the shelf life quality of mature mango. Specifically, it aimed to determine the time of exposure that will give the optimum marketable quality of mature mango. Prior to storage, mature mango samples were subjected to acoustic wave 1 KHz at 100 dB.
Mature mango fruits from the farm were exposed to acoustic waves at different levels: T1 (control treatment)- zero exposure; T2 - 4 hours of exposure; T3 - 6 hours of exposure; and T4 - 8 hours of exposure. Subsequrntly, mature mango were stored in a chiller at 10°C. Considering the surface color, total soluble solids content and flesh firmness, the optimum exposure time of mature mango to acoustic waves that can give the best physiochemical and mechanical properties was determined.
Result showed that under zero exposure, samples were marketable until the 11th day of storage. Four hours of exposure gave the best physiochemical and mechanicalproperty of mature mango. It also gave the optimum shelf life of the mature mango quality with 23 days. On the other hand, additional marketable days of 9, 6, and 3 for exposure time of 4 hours and 8 hours, respectively.
Over all, it can be concluded that the most effective treatment in this study was the Treatment 2 (4 hours of exposure). Moreover, acoustic waves effectively slowed down the ripening and deterioration of the mango.
