Rheological and Stability Evaluation of Emulsions Containing Fenugreek Galactomannan—Xanthan Gum Mixtures: Effect of Microwave and Ultrasound Treatments

The effects of treating two biopolymers (Trigonella foenum—graceum galactomannan and xanthan gum mixtures) with microwaves ultrasound on the rheological aspects O/W emulsions were investigated. data obtained from steady shear flow fitted various models best chosen due to values R2 RMSE. oscillatory rheology demonstrated that not treated or had viscous-like behavior samples weak gel behavior. for parameters (especially apparent viscosity, storage modulus loss modulus) indicated fenugreek more impact in comparison gum. In addition, synergistic interaction between biopolymers, particularly ultrasound, resulted better which could be affiliated strong bonds hydrocolloids. By emulsion stability those a high ratio galactomannan) significantly increased, might connected parameters, especially viscosity.
