Optimising the Encapsulation of an Aqueous Bitter Melon Extract by Spray-Drying.

Our aim was to optimise the encapsulation of an aqueous bitter melon extract by spray-drying with maltodextrin (MD) and gum Arabic (GA). The response surface methodology models accurately predicted the process yield and retentions of bioactive concentrations and activity (² > 0.87).

An Optimised Aqueous Extract of Phenolic Compounds from Bitter Melon with High Antioxidant Capacity.

Bitter melon (Momordica charantia L.) is a tropical fruit claimed to have medicinal properties associated with its content of phenolic compounds (TPC). The aim of the study was to compare water with several organic solvents (acetone, butanol, methanol and 80% ethanol) for its efficiency at extracting the TPC from freeze-dried bitter melon powder.
