Assemblies with multiple domains have been suggested as potential carriers for co-encapsulation of bioactive components with different solubilities. Although protein emulsion gels contain a dispersed oil phase and a gel network, there is no report about their use for co-encapsulation. Heat-denatured WPI particles and emulsions with 10% and 25% oil were characterised by size, zeta-potential and viscosity. The total encapsulation efficiency of resveratrol and alpha-tocopherol was around 60% and 98%, respectively, most located in the oil droplets. Cold-set gels were further fabricated with 10-100 mmol L-1 CaCl2 and characterised in terms of syneresis, water holding capacity and hardness. During in vitro digestion, alpha-tocopherol and resveratrol were completely released from the gels. After digestion, resveratrol remained above 50% and the highest (similar to 85%) at 10 mmol L-1 CaCl2 in the absence of oil, but ci-tocopherol remained only 25%. These results should be useful for the development of co-encapsulating carriers. (C) 2020 Elsevier Ltd. All rights reserved.
