Abstract:
The main problem of the dehydrated jackfruit developed by the Visayas
State University (VSU) is that it develops browning after one to two months even
if the product is packed in a good packaging material. This study was conducted
to determine the effects of variety and sulfite in controlling browning within 4
months of storage of dehydrated jackfruit pulp. Two recommended jackfruit
varieties (AES Jak 1 andAES Jak 2) and two levels of sulfite (0.1 and 0.2% w/w)
were used in the study. Treatments were laid out in CRD with three replications.
Data were analyzed using SPSS version 16 and HSD was used to test the
significance between treatments. Different parameters on physico-chemical
properties and functional components of the product were investigated at 0, 2
and 4 months of storage.
Results revealed that utilization of AES Jak 1 variety and either 0.1 or 0.2%
w/w sulfite can be used in dehydrated jackfruit processing with least browning
during storage. Correlation analysis showed that as pH and TTA increase, DB
decreases which indicates that pH and TTA can be used as control in minimizing
browning. The weak correlation of TP and TC on DB implies that browning of
stored dehydrated jackfruit is caused by non-enzymatic reaction.
