Comparison of the physical properties and microstructure of bigels prepared from ethyl cellulose oleogels and konjac glucomannan hydrogels containing casein or whey protein isolate.

ABSTRACT: Bigels were prepared from ethyl cellulose oleogels and binary hydrogels containing konjac glucomannan (KGM) and two homologous proteins: casein (CS) and whey protein isolate (WPI). An increase in CS concentration led to an initial enhancement, followed by a reduction in the yield stress and hardness of the bigels. Conversely, variations in WPI concentration did not have a significant effect on these properties. As protein concentration increased, WPI-based bigels maintained the hydrogel-in-oleogel structure, whereas CS-based bigels exhibited phase inversion. The change in binary hydrogels was responsible for the structural evolution and property differences in bigels. Both CS-KGM and WPI-KGM binary hydrogels played a role in stabilizing the droplets and decreasing interfacial tension. Nota
