This study was performed to evaluate the effects of chicken breast meat on the quality of mackerel sausages. The mackerel sausages were manufactured by additions of 5%, 7%, and 10% of chicken breast meat. The lightness of mackerel sausages showed no significant differences between the control and addition groups. The redness increased in a dose-dependent manner, but the yellowness decreased significantly with the addition of 7% chicken breast meat (p<0.05). The whiteness value of mackerel sausage added with 7% chicken breast meat was significantly higher than those of the other groups (p<0.05). In texture analysis, the hardness and adhesiveness of the mackerel sausage added with 5% of chicken breast meat showed no significant differences as compared to the control. However, the mackerel sausages added with 7% and 10% of chicken breast meat showed a dose-dependent decrease. The gel strength of the mackerel sausage added with 5% chicken breast meat was not significantly different from the control, but the addition of 7% and 10% chicken breast meat reduced the gel strength of the mackerel sausage. In sensory evaluation, the mackerel sausages prepared with chicken breast meat have higher scores in smell, taste, texture, hardness, chewiness, and overall preference as compared to the no addition group. Therefore, these results suggest that the optimal condition for improving the properties within mackerel sausages was 5% addition of chicken breast meat.
Processing conditions of mackerel sausage were optimized for number of washes (0, 1, 2, and 3 times) and percentages of various additives: salt (1, 1.5, 2, 3%), phosphate complex (0.1, 0.3, 0.5%), sugar (1, 2, 3%), and corn starch (1, 3, 5%). The whiteness of mackerel sausage significantly increased with increasing washing time, but the whiteness of mackerel sausage prepared with additives did not show large differences. Conditions consisting of two washes, 2% salt, 2% sugar, and 5% corn starch showed the highest hardness and gel strength, whereas the group supplemented with phosphate complex showed no considerable differences compared to the control. In the sensory evaluation, the mackerel sausage prepared with two washes compared to the control scored higher for color, aroma, and overall preference. In addition, mackerel sausage supplemented with 2% salt, 2% sugar, and 5% corn starch scored highest in overall preference. There was no significant difference in mackerel sausage supplemented with phosphate complex. Therefore, these results suggest the optimal conditions for improving the texture and sensory properties of mackerel sausage were two washes, 2% salt, 0.5% phosphate complex, 2% sugar, and 5% corn starch.
This study was conducted to evaluate the qualities of mackerel Scomber japonicus sausage prepared with Theragra chalcogramma surimi (TS, A grade), Nemipterus virgatus surimi (NS, A grade) (0, 5, 7, 10%), and 7% NS with starch (0, 1, 2, 3%). The whiteness of the mackerel sausage was significantly increased by adding TS and NS, but that of the NS with starch groups was decreased compared with the control. The hardness increased significantly with the addition of TS, whereas the NS and NS with starch groups showed no considerable differences compared with the control. The gel strength was not significantly different among the mackerel sausage additive groups. In the sensory evaluation, the mackerel sausages containing 5% TS, 7% NS, and 7% NS with 2% starch had the highest overall preference. In conclusion, these results suggest that 5% TS, 7% NS, and 7% NS with 2% starch improve the quality, texture and sensory properties of mackerel sausage.
