Conclusions
High methoxyl pectin was extracted from dragon fruit peel using
1% citric acid. The physico-chemical characteristics of the
dragon fruit peel pectin were comparable to that of commercial
pectins except for the viscosity. However, the dragon fruit peel
pectin can be utilised as a functional ingredient in low viscous
foods. Both technological and health functional characterisations
should be performed to further understand its behaviour in food
and the health benefits it may provide.
