**studies which reported beneficial effects at much lower US intensities. Siró et al. (2009) and Cárcel et al. (2007) reported that 2.5 Wcm-2 (180min) and 39 W cm-2 (45 min) respectively will cause water mass transfer and binding. However, Siró et al. (2009) reported decreased water – uptake and binding. With higher US intensities (3 – 4 W cm-2) attributing this to protein denaturation. In a study using the same treatment chamber, M cDonnell et al., (2003) (19 W cm-2 (40 min) which may explain the results of the present study whereby this treatment did not result in the greatest water uptake.
