説明

Aqueous solution (pH 4, 7 and 9), formulated diet, and minced mackerel supplemented with L-ascorbic acid (AA), L-ascorbyl-2-O-α-glucoside (AA-2G) or L-ascorbyl-2-phosphate Mg (AA-2P) were prepared and stored at 5, 23 or 37°C for 3-30 days. These materials were sampled periodically and the concentrations of AA, AA-2G, and AA-2P were determined by high performance liquid chromatography to estimate the stability of these compounds under storage. AA-2G and AA-2P were stable under all conditions of pH and temperature, while AA was unstable in aqueous solution and in the formulated diet. The stability of AA decreased as pH and temperature increased. The stability of AA-2G, AA-2P, and AA in minced mackerel decreased as temperature increased.
