Abstract

The effect of vinegar concentration (+30%, 0% and -30%) on the emulsion stability of mayonnaise dressing was studied by the measurement of theological test and sensory evaluation. The emulsion stability of mayonnaise dressing increased with increase in vinegar concentration. The results of steady shear theological test indicated that C sample of the highest vinegar concentration (+30%) exhibited higher emulsion stability than other samples. The dynamic shear datas were similar to steady shear theological data. The mayonnaise dressing samples showed time dependence, which was quantitatively described by the Weltman model. Parameters A and B indicated that the structure of C sample exhibited more stable than that of A (-30%) and B (0%) samples. The amount of oil separation was less than that of A and B samples. The results of sensory evaluation were similar to those of theological and emulsion tests.
