Abstract
Imitation crab stick samples were made from Alaska pollack with Golden treadfin bream surimi (C), Alaska pollack with Golden treadfin bream surimi and spent laying hens breast surimi (T1), Alaska pollack with spent laying hens breast surimi (T2), and Alaska pollack with Golden treadfin bream with mechanically deboning chicken meat (MDCM) (T3). Crude protein was significantly lower in T2 and T3 compared with C and T1. However, crude fat and carbohydrate were not significantly different among the samples during storage periods. pH steadily increased until 2 weeks of storage thereafter pH was decreased in all samples. Lightness (L ∗) and whiteness (W) were significantly lower in T3 than those of other samples. In fatty acid composition, the amount of polyunsaturated fatty acids such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) was higher than other fatty acids in all samples at 0 week of storage period. TBARS (thiobarbituric acid reactive substances) value was highest in control sample compared with other samples. In sensory evaluation, color was the highest in C than other samples, whereas T3 was lowest in color than those of other samples. Overall acceptability was significantly highest in T1 compared with other samples during the storage periods.
