The effect of maltodextrin (MDX) concentration on the stability of multilayer linseed oil-in-water emulsions before and after freeze-thawing has been studied. Interfacial double-layer emulsions were obtained by performing electrostatic deposition of sodium alginate (SA) onto whey protein isolate (WPI) coated oil droplets at pH 5 (10 wt% oil, 1 wt% WPI 0.25 wt% SA). MDX was also added to emulsions formulation in different concentrations (0-20 wt%), and the systems were then stored at two freezing temperatures (-18 and 80 degrees C). Stability of emulsions was studied using droplet size, zeta-potential, as well as microstructure determinations and monitoring backscattering profiles versus time. Non-frozen emulsions showed smaller droplet sizes at higher MDX concentrations thus reducing creaming mechanisms and improving emulsion stability. In the absence of MDX, emulsions were highly unstable after freeze-thawing and destabilized faster at -18 degrees C than at 80 degrees C, which was attributed to the formation of larger ice crystals at slower freezing rates that promoted interfacial membrane disruption leading to extensive droplet coalescence and oiling off. Both systems showed macroscopic phase separation within the first hour of analysis. The addition of MDX greatly improved emulsion stability after freezing, as emulsions showed no phase separation after thawing during one week storage. This behavior was attributed to MDX cryoprotectant effect, that could have considerably reduce the amount of ice formed during freezing, thereby maintaining the integrity of the interfacial WPI-SA bilayer surrounding oil droplets. Our results suggest that 20 wt% MDX emulsions were the most stable systems both to creaming destabilization and to freeze-thawing processes. (C) 2015 Elsevier Ltd. All rights reserved.
