This study investigated the impact of adding beta-carotene on the structure of fresh O/W emulsions with different oil phase (sunflower oil-LCT or NEOBEE (R) 1053-MCT) and emulsifiers (WPI, Tween 80 - T80 or WPI/T80 mixture). In this sense, the behavior of emulsions through the gastrointestinal tract, the stability and bioaccessibility of beta-carotene were also assessed. The beta-carotene reduced the interfacial tension of the LCT/MCT-water systems. The addition of beta-carotene promoted an increase of viscoelasticity of LCT/MCT-T80 (0.5% WPI/0.5% T80 and 1% T80 w/w) interfaces, but an increase of WPI content reduced the viscoelasticity of interfacial layers (LCT/MCT-1% WPI). These changes in the interface properties influenced the mean droplet size and zeta-potential of the fresh emulsions. LCT systems presented similar bioaccessibility/stability of beta-carotene. However, beta-carotene entrapped within protein-coated MCT droplets was more stable than within T80-MCT systems. Our results show that beta-carotene interacted with other ingredients of emulsions changing their properties and behavior under gastrointestinal tract as well as the stability/bioaccessibility of beta-carotene.
