Flow properties of fruit purees are of considerable interest in the development of fruit products for
technological and marketing reasons. Together with others, they provide the information necessary for the
optimum design of unit processes; contribute to the quality control in both manufacturing processes and
final product; limit the acceptability and the field of application of a new product; and finally, they are a
powerful tool into understanding molecular structure changes [3]. Moreover considering the consumer
demand for processed foods with high quality, there is a need to define changes in rheological properties
of foods in processing operations and during the storage that may affect their overall acceptability [4].
