Zusammenfassung:	Bioactive compounds and physical properties of Roselle ( Hibiscus sabdariffa L. calyces) are of interest in food, cosmetics and pharmaceutical industries. The objective of this study was to relate water activity with the extractable polyphenols and physical properties of freeze- dried calyces stored at 35 °C for 49 days. The minor changes in soluble phenols, monomeric anthocyanins, antioxidant activity and color were found at a w ’s
