The salting-smoking process periodically performed from frozenfish species gave rise to a decrease in protein functionality,
namely a total loss of apparent viscosity (it could not be measured for this reason) and a loss of protein solubility (Fig. 3). The WHC was generally increased, especially at the beginning of the frozen storage (Fig. 2). It is especially remarkable the evident loss of protein solubility observed in the dolphinfish at the end of the storage and the drop in WHC in the lean sardine after the third month of storage. Fat release (Table 2) was proportional to the fat content, as described for both frozen sardine and dolphinfish. In
