Optimización acoplada taguchi-RSM de las condiciones de emulsificación por microfluidización de α-tocoferol en una matriz de goma arábiga y maltodextrina

The effect of composition (Arabic gum (AG), maltodextrin (MD), surfactants, pH) and processing parameters (pressure and number of cycles of microfluidization) of ff-tocopherol (AT) emulsions was studied via a coupled Taguchi-RMS optimization. Creaming index (CI), particle size (PS) and zeta potential (ζ) were selected as response variables. The estimated optimal conditions were found at GA of 40%, MD/surfactant mixture of 60%, 30% AT, pH of 4.9, P of 76 MPa and five cycles of microfluidization for a predicted CI of 0.5 % at 24 h with a PS of 384 nm. Under these conditions the experimental results were 437 nm and 0.5 CI. It was possible to minimize the CI by varying the concentration of GA and modifying processing conditions.
