The influence of US treatment was also noticeable after drying
and during storage in terms of dry matter content and water activity
(Table 4). The increase in solids gain during osmotic treatment
resulted in a higher dry matter content after 9 h of convective
drying. At the beginning of the shelf-life test (0 weeks) the dry
matter content amounted to 74.8% and 72.1%, respectively for
sonicated and not sonicated samples
