In addition, the steady and dynamic shear properties were optimized using ridge analysis in terms of amplitude level, sonication temperature and exposure times levels. Increasing amplitude level and sonication time decreased considerably the ?, ?, K, G?, G? and ? values of salep dispersions (SS and SD samples). However, sonication temperature did not have a remarkable effect on these properties. © 2011 Elsevier B.V.
