To evaluate the effects of sucrose replacement by polyols on pH value, surface tension and apparent viscosity of LWE, LWE solutions were prepared.According to the formulation of sponge cake, 180 g LWE and 100 g sweeteners were poured into a mixer bowl (5K5SS Kitchen Aid Mixer, St. Joseph's, MI, USA) and mixed by a wire whip at room temperature (25 C), until the sweeteners were completely dissolved.
