Abstract

The objective of this study was to develop, characterize and compare quercitin loaded nano and microemulsions systems. Oil in water emulsions were prepared using a high speed homogenizer (Ultra Turrax) and a high pressure homogenizer (HPH, Emulsiflex-C5, 500-1200bar). Hydrocolloids incorporation, Beta-lactoglobulin concentration and volumetric fraction variation were evaluated. Emulsifyng capacity and stability were analyzed by light backscattering (Turbiscan Classic) and droplet profile analysis (Malvern Zetasizer Nano). Using the Ultra Turrax optimum conditions for stability with a suitable particle size (d<500nm) were achieved with a concentration of 2.2 % (m/v) protein and between 0.1-0.2 % (m/v) of guar gum, while using HPH emulsions showed higher stability (α <0.05) achieved at a concentration of 1.5 % of Beta-lactoglobulin (m/v) and without using hydrocolloids. Emulsions made with high pressure achieved greater percentage of quercetin encapsulation.
