Addition of sodium chloride: Sodium chloride has
shown the ability to inactivate autolytic enzymes in
marine species. reported the
inactivation of cathepsin extracted from winter flounder
using 5% NaCl when incubated for 25 h at room
temperature. They concluded that NaCl is an inactivator
of catheptic activity, which may, also, control autolytic
spoilage. The effect of NaCl on cathepsin is shown
