These sample data received show the inhibition
potency on extracts of peel, cinnamon, and the citrus
oil that can be considered as preservative agents for
both antibacterial and antioxidant activities. This
study provides the important baseline information
for the use of extracted peel from G. mangostana as
well as the essential oils as the preservative agents for
some types of food. Then in vivo experiment should
be conducted for further study. The antibacterial and
antioxidant studies of these peel and essential oils
are being considered as the future objective for the
planning of using these potential preservation agents
in fresh-cut mangosteen.
