TLDR
In this paper, different malonaldehyde-amine condensation products were tested for their relative color contribution to the thiobarbituric acid (TBA) test, an indicator for oxidative rancidity of polyunsaturated lipids.Abstract:
Different malonaldehyde-amine condensation products were tested for their relative color contribution to the thiobarbituric acid (TBA) test, an indicator for oxidative rancidity of polyunsaturated lipids The open chain mono- and disubstituted malonaldehyde (M) addition products (R-N=CH-CH=CHOH and R-N=CH-CH=CH-NH-R) gave complete (100%) recovery ofM on a mole basis When theM residue was incorporated into cyclic products which formed between the ureido- or guanidino- substituents of α-amino acids such as citrulline or arginine andM, recovery ofM by the TBA color test was 30% and 6%, respectively Products, from imine-amine type interactions, containing theM residue as in pyrazoline or pyrazole ring systems, released from 4% to noMread more

Malondialdehyde and thiobarbituric acid-reactivity as diagnostic indices of lipid peroxidation and peroxidative tissue injury.
TL;DR: The conclusion is reached that MDA determination and the TBA test can offer, at best, a narrow and somewhat empirical window on the complex process of lipid peroxidation.

R.P. Bird,H.H. Draper +1 more
TL;DR: Malonaldehyde is of interest primarily as a product of lipid peroxidation in vivo and as an index of oxidative rancidity in foods and reacts with a variety of compounds to form derivatives, which can be estimated spectrophotometricaily.

The thiobarbituric acid (TBA) reaction in foods: a review.
TL;DR: The wide diffusion of 2-thiobarbituric acid (TBA) in the scientific literature is due to the TBA assay, or TBA test, which has been employed in the determination of autoxidative alterations of fats and oils.

Protein changes in frozen fish
Z Sikorski,J Olley,S Kostuch +2 more
TL;DR: Retardation of the deteriorative changes of proteins in frozen fish is possible by avoiding high storage temperatures and oxidation of lipids, removing hematin compounds and other constituents promoting cross-linking reactions, and by adding cryoprotectors like sugars, several organic acids, amino acids, or peptides.
