Abstract:A rheometer was employed to study the effects of four ingredients in chicken surimi (myofibrillar protein, fat,
starch, salt and soy protein) on starch retrogradation during storage. Myofibrillar protein and fat at higher levels exhibited
a greater inhibitory effect on starch retrogradation; this effect was more evident with prolonged storage time. After
different storage times, the inhibitory effect of fat and soy protein rose at first and then dropped with increasing levels.
From orthogonal array experiments, it was found that the lowest extent of starch retrogradation was obtained when 1.00%
myofibrillar protein, 1.50% fat, 4.00% salt and 4.00% soy protein were added. In addition, the importance of the ingredients
followed the decreasing order: salt, myofibrillar protein, fat and soy protein.
