The gel strength of minced mackerel with MTGase alone at a concentration of 0.47 unit/g reached 1789 g.cm, which was 3 times greater than that of control. When MTGase-supplemented minced mackerel was exposed to UV light for the optimal irradiation time of 20 min, the gel strength could be further increased by 25%. SDS-PAGE analysis suggested that UV irradiation accelerated the MTGase to catalyze the cross-linking of myosin heavy chains in mackerel actomyosin. |
