魚肉のビタミンAに關する研究-II

体側の左右によるビタミンA含量の差異

抄録

In the previous work when the authors studied the vitamin A content in fish meat by the anatomical locality, all the samples were taken from one side of the bodies.
The present paper deals with the difference in vitamin A content of the meat sampled from the left and right sides of fish body.
In the sardine, a filefish Cantherines modestus, Promethichthys prometheus and harvest fish Pampus argenteus, the vitamin A content in meat is not always equal to each other side of the body (Tables 1-5, Figs. 1, 2).
In flatfishes, the vitamin A content in meat of the eyed sides are higher than that in the blind sides. In the case of meat of flounder, Paralichthys olivaceus, the difference in vitamin A content between both sides is remarkable on the surface layer but very small on the inner layers (Tables 6-8, Figs. 3, 4).
