A rapid method of total lipid extraction and purification.
The lipid decomposition studies in frozen fish have led to the development of a simple and rapid method for the extraction and purification of lipids from biological materials that has been applied to fish muscle and may easily be adapted to use with other tissues.
Proteins in Fish Muscle.: I. Extraction of Protein Fractions in Fresh Fish
Methods for the extraction of protein from fish muscle have been studied. Using the Waring Blendor to obtain fine subdivision, up to 95 per cent of the fish muscle protein can be extracted with 5 per…
Amines in Fish Muscle: I. Colorimetric Determination of Trimethylamine as the Picrate Salt

- 1 May 1945
A sensitive accurate colorimetric method for trimethylamine determination is presented, based on the extraction with toluene of an alkaline sample containing 0.002 to 0.02 mg. trimethylamine…

Principal Acid-Soluble Nucleotides in Adductor Muscle of the Scallop Placopecten magellanicus and Their Degradation during Postmortem Storage in Ice
In scallop adductor muscle stored at 0 C, a rapid turnover of the intermediates in the degradative sequence, indicating relatively high activities of the enzymes catalyzing these reactions, resulted in the formation of appreciable amounts of Hx within the edible storage period.
Amines in Fish Muscle: II. Development of Trimethylamine and Other Amines
Relatively large amounts of nonvolatile higher amines are formed during proteolysis of fish muscle by bacteria. This follows closely the formation of trimethylamine. Fresh fish contain 0.2 mg.…
Simultaneous Measurements of Trimethylamine and Dimethylamine in Fish, and Their Use for Estimating Quality of Frozen-Stored Gadoid Fillets
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)…
