The objective of this study was to investigate Alaska pollock Theragra chalcogramma roe grade distribution among
blocks and its nutritional components by grade. M grade roe was predominantly distributed in blocks labeled as L and
M (52.1 and 82.8%, respectively), and S grade roe was mainly found in blocks labeled as S (98.6%). Products labeled
as containing KB and KC grade roe contained 77.1 and 65.5% normal roe, respectively. Among the five roe grades
(L, M, S, G, and Off), total amino acid content was higher in normal roe than in abnormal roe. The major amino acids
found in normal roe were leucine, aspartic acid, and glutamic acid, whereas G and Off grade roe contained leucine
and glutamic acid, but not aspartic acid. The calcium, phosphorus, potassium, and iron contents of the five roe grades
were within the ranges 13.0-20.0, 314.4-392.0, 124.1-157.7, and 1.7-2.2 mg/100 g, respectively. The five roe grades
contained total fatty acid contents of 765-1,252 mg/100 g, with no significant differences among grades. The major
fatty acids were 16:0, 18:1n-9, 20:5n-3, and 22:6n-3.
