Abstract The first action modified Babcock method for crude fat in canned fish, 18.013, was studied collaboratively on 2 samples of canned fish and 2 samples of frozen fish. The results were compared with those by the official acid hydrolysis method, 18.012. Nine analysts, representing 5 different laboratories, cooperated in the study. The results show that the modified Babcock method has about the same degree of reliability as the acid hydrolysis method. It was recommended that the method be made official, after some slight changes in the wording.

Abstract The first action rapid modified Babcock method for crude fat in canned fish (18.013) was again studied collaboratively. Two samples of fresh (unfrozen) fish were examined by 6 analysts in 3 different laboratories. The same fish (frozen) together with samples of canned tuna, canned salmon, and a mixture of raw sablefish and canned tuna were examined by a total of 12 analysts in 6 different laboratories. Each analyst also determined fat by the official acid hydrolysis method (18.012). The results show that the rapid modified Babcock method (18.013) has the same degree of reliability as the acid hydrolysis method; it has been rewritten for greater clarity following the suggestions of the collaborators, and the revised form is recommended for adoption as official, final action.

Theoretical Considerations

1. The water, ash, glycogen, nitrogen, and ether extract content of the tissues of chicken embryos were determined between the 5th and the 19th days of incubation. 2. It was found that the concentration of solid substance changed from approximately 5 to 17 per cent during this interval. The chief change in the organic substances involved a relative decrease in the nitrogen as compared with the fat. 3. Bomb calorimetric estimations confirmed these findings. It was shown that the calorific value of the dried substance increased with age. 4. The rate of growth of the total solids, and of the potential energy of the tissues was estimated. 5 Various theoretical considerations were brought forward dealing chiefly with the order in which the chief organic substances, carbohydrate, protein, and fat could be ranged when judged by various criteria.
