To obtain a method suitable for determining the BHA added to marine products, three colorimetric methods were compared with one another: 2, 2-dipyridyl (2, 2-DP) method3), 2, 6-dichloroquinonechloroimide (2, 6-D) method 4), and potassium ferricyanide (K3(CN)6) method6). The antioxidant was drawn from the products together with crude oil by the Soxhlet extraction extended over 16 hrs., using peroxide-free ethys ether. After evaporating-off the solvent under reduced pressure, BHA was extracted by a modified method (see Table 1), and subjected to each colorimetric estimation mentioned above. From the results obtained, only the 2, 6-D reagent towards BHA. In the case of the other two methods, the reagents reacted with some other materials coming dissolved in alcoholic extracts of crude oil. It is possible, therefore, when the estimation is made with any of the latter methods, that the results become too large and misrepresent spurious substance as BHA. Consequently, the said two methods should be regarded as inapplicable to the case of marine products.
