  • The interactions between polyelectrolytes Mesquite Gum and Chitosan at the water-Canola oil interface are analyzed, measuring the interfacial apparent viscosity and interfacial creep-compliance properties of the adsorbed polymer films.

  • The morphological characteristics, rheological properties and stability of simple emulsions O/W and multiple emulsions W1/O/W2, formulated with Mesquite Gum-Chitosan complexes, are evaluated.

  • The use of a cationic polysaccharide, such as Chitosan, combined with an anionic hydrocolloid with more surface activity, like Mesquite Gum, form electrostatic complexes in aqueous solutions. These interactions allow the formulation of stable multiple emulsions W1/O/W2.
