| dc.description.abstract | Despite being a rich source of bioactive compounds, the peel of mangosteen is
usually regarded as food industry waste. In this study, microwave applications and
enzyme treatment - Cellulase Onozuka R-10 (50 U/mg) were combined in numerous
ways in order to investigate their effects on the simultaneous extraction of
polysaccharides (PSs) and polyphenols (PPs) from the peel of mangosteen. More
specifically, the yields of these compounds were researched under a wide range of
enzyme concentrations (0-2.5%) and enzyme incubation time (0-150 minutes), with
and without the aid of microwaves. The results revealed that the suitable conditions
for the extraction of each method were at an enzyme concentration of 2% for 120
minutes for enzyme extraction alone (EA), at 1.5% for 120 minutes for microwave
application before enzyme extraction (MBE), and at 1.5% for 90 minutes for
microwave application after enzyme extraction (MAE). Under the ideal conditions, the
yields of PSs and PPs in EA, MBE, and MAE were 33.47±3.05% and 17.36±0.89%;
41.78±2.31% and 19.39±0.95%; and 43.13±2.40% and 22.15±1.06% respectively.
Additionally, the yields of PSs and PPs in combined methods (MAE & MBE) were
significantly higher than those of single-method extraction (EA) at several levels of
investigated parameters (p<0.05), indicating the substantial impact of combining
microwave and enzyme extraction. Consequently, microwave-assisted enzymatic
extraction (MAEE) of PPs and PSs from mangosteen’s peel can be utilized to improve
economic performance and contribute towards environmental conservation. | en_US |
