Abstract

The rheological properties and physical stability of mangosteen (Garcinia mangostana L.) extract in oil-inwater (MIO/W) emulsions were investigated. Rheological study on the emulsions exhibited Newtonian flow behavior. The 20 wt.% emulsion showed higher apparent viscosity than 10 wt.% MIO/W sample. The effects of salt (NaCl) concentration (0, 50, 100, and 200 mM) and heat treatment (70 °C) on the stability of the emulsions were also examined. Heat (70 °C)- and NaCl (100 and 200 mM)-treated emulsions showed creaming and droplet aggregation on storage for a period of 60 days. The 10 wt.% MIO/W emulsions stored at 4 °C showed a homogeneous distribution of oil droplets with good stability to creaming and viscosity independent of shear stress (i.e., a Newtonian liquid).
