However, when using sugar replacers, product structure can be negatively altered. The effect on air cell development and microstructure with the use of Stevianna, or inulin, as sugar replacer was evaluated using muffins as a model food. The total replacement of sugar using Stevianna or inulin resulted in the development of non-uniform air cells leading to poor muffin microstructure. However, formulations involving partial sugar replacers gave similar air cell characteristics and hence microstructural characteristics, to that of the control sample.
