## Abstract A model system was used to study the pattern of rancidity in linoleic acid and corn oil using the TBA method. It was shown that malonaldehyde is not a stable end product of rancidity and therefore, the TBA test is not a reliable means of quantitative feasurement of degree of rancidity i
Rancidity of frozen fish (Baltic cod and herring, mackerel, horse mackerel and hake) was determined by means of TBA value, organoleptical scoring and peroxide value. The correlation between the rancid odour sensory assessment and TBA test results proved insignificant ( I = 0.53). Model experiment wa
