Rheological and microscopic studies were carried out on the fish cracker ('keropok') gels. A hard gel is very important for the production of uniform, round, and thin slices of dried 'keropok' and easier for mechanical slicing. The addition of 2% salt in the 'keropok' gel increased the storage modulus (G'), and reduced loss tangent (tan delta = G"/G'). An increase in the fish content in 'keropok' also increased the G' and reduced tan delta. Gels having higher values of storage modulus G' and lower tan delta values, indicative of a strong elastic network, showed well crosslinked fish muscle bundles in the microscopy studies. In the absence of salt, the fish protein appeared to be in lumps and this has resulted in low storage modulus G' and higher tan delta values. Lower the temperature of the gel to 5C will result in 5-6 fold increase in the G' value.
