The control had the highest storage moduli and increasing replacement of shortening with Nutrim OB caused a decrease in the storage modulus. The same trend was observed in the loss modulus. The dynamic viscoelastic properties decrease with increasing moisture content in dough (Navickis et al., 1982; Dreese et al., 1988). Thus, the decrease in the dynamic viscoelastic properties of cookie doughs containing Nutrim OB would be attributed to their increased moisture content.
