The present study compared the sensory and physicochemical characterizations of Alaska pollock Theragra chalcogramma roe according to the L, M, S, 2S, KA, KB, KC, and G grades. The mean weights of the Alaska pollock roe were 81.2 g (74.1-85.7 g) in the L grade, 48.4 g (41.1-54.8 g) in the M grade, 38.6 g (33.5-45.6 g) in the S grade, 29.3 g (25.7-34.2 g) in the 2S grade, 45.7 g (41.4-50.0 g) in the KA grade, 41.4 g (37.7-46.1 g) in the KB grade, 38.3 g (36.0-42.6 g) in the KC grade, and 15.0 g (14.2-15.6 g) in the G grade. The results of the sensory (transparency, physical damage, texture, and odor) and physicochemical (moisture, amino nitrogen and volatile basic nitrogen contents, Hunter redness, and texture) evaluations revealed that, in the normal group, the quality of Alaska pollock roe was highest in the L grade followed by the M, S, and 2S grades whereas, in the cut-group order, the quality was highest in the KA grade followed by the KB, KC, and G grades. The present results suggest that the L, M, S, 2S, KA, and KB grades could be used for high-quality Alaska pollock roe products
