The present work was aimed to study the oxidative
deterioration of lipid profile in Indian mackerel (Rastrelliger
kanagurta) at an accelerated storage temperature.
Fatty acid (FA) composition and oxidative changes were
analyzed at regular intervals. Initially, the total polyunsaturated
fatty acid (PUFA) content was predominant followed by saturated
(SFA) and monounsaturated fatty acids (MUFA). With increase
in storage period, the decrease in PUFA content was significantly
higher (P < 0.05) than SFA and MUFA. Among the essential
FAs, ù-3 FAs were more predominant and with the storage period
they showed a decreasing trend whereas the lipid oxidation
products viz., peroxides, malonaldehyde and free fatty acids
(FFA) increased significantly. The decrease (P < 0.05) in PUFA
compounds (82.5%) has been as follows: ù-3 , ù-3 / ù-6
ratio (66.65%), PUFA/SFA ratio (66.3%) and Polyene index (PI)
(82.24%) at the end of storage period. In addition, the peroxides
and malonaldehyde contents showed a negative correlation (r
2
= 0.98 and 0.96 respectively) with PUFA and FFA showed a
negative correlation (r
2 = 0.98) with phospholipids indicating
the overall loss of valuable lipid fractions with the storage
period. The study provides strong evidence that, oxidation of
lipid affects nutritional quality of mackerel.
