On the basis of some of the recent modifications of Dyer's colorimetric test for measuring trimethylamine (TMA) in fish, a procedure is described that gives both the TMA and the dimethylamine (DMA) contents. Measurements on 84 frozen-stored fillets o

Small amounts of nitrite slowly accumulated in cod fillets that had been dipped in a solution of hydroxylamine. Cultures of Pseudomonas isolated from fish, as well as two species of Proteus and one species of Microbacterium, were able to convert hydr

A method that can be carried out within 24–72 hr is suggested for determining the tendency of fish muscle to become rancid. It consists of adding measured, trace amounts of copper ion to muscle that has been blended with water (1:3) followed by sto

Erroneously high TBA values were obtained from liver, dark muscle, and certain other organs taken from seven species of sea fish. This error was eliminated by carrying out a portion of the test under anaerobic conditions or, more simply, by adding a

It was observed that a reduction in storage temperature from 2.8 °C. to − 0.3 °C. approximately doubled the keeping time for haddock and cod fillets as judged by the development of trimethylamine. This reduction of 3° in the region of the freezi

Storage studies of iced irradiated scallops (Placopecten magellanicus Gmelin) have shown that treatment with a dose of 75,000 rads of gamma radiation increases the useful storage life at 0 °C with negligible changes in odour and texture. The raw sca

A study has been made of the landed quality (i.e. the quality at the time of discharge from the vessels) of trawler-caught, gutted and iced market cod and large haddock. The rate of deterioration, as indicated by the rise in TMA values, varies with t

The accuracy of the trimethylamine (TMA) grade probability curve, developed in 1958 by Hoogland for gutted, trawler-caught Atlantic cod and haddock has been verified by tests made on 3170 cod and haddock.It has also been shown that the relation betwe

Panels of experienced fish-plant foremen and government fresh-fish inspectors graded cod and haddock in the round or as gutted whole fish, and subsequently graded the same fish as fillets. The results show that in general the two sets of gradings wer

In a study of copper-catalyzed rancidity of cod fillets it has been found that: (1) muscle from the tail section goes rancid faster than muscle from the head or centre sections; (2) there is no apparent difference in the development of rancidity in t
