Influence of water and glycerol contents on the aw of fish pastes
The influence of fish water content on the characteristics of water activity (aw) of reduced paste was studied. Two fish species were used: a fat species, mackerel (Scomber japonicus marplatensis), and a lean species, Brazilian sandperch (Pseudopercis semifasciata). Glycerol (from 15 to 50%) was use...
