Microencapsulation of Polyphenols from Orthosiphon stamineus Leaves Extracts using Polysaccharide and Protein

This paper presents the Orthosiphon stamineus polyphenol extraction and microencapsulation study using whey protein isolate, gum arabic and maltodextrin. Polyphenol content was analysed using ultra-performance liquid chromatography. The highest yield of rosmarinic acid (38.70 mg RA/g DW) was obtaine...
