Relationships between 4-Hydroxy-2-nonenal, 2-Thiobarbituric Acid Reactive Substances and n-6 Polyunsaturated Fatty Acids in Refrigerated and Frozen Pork

The relationships between 4-hydroxy-2-nonenal (HNE), 2-thiobarbituric acid reactive substances (TBARS) and n-6 polyunsaturated fatty acids (n-6 PUFAs) were investigated for pork stored at 0, -20 and -80 degrees C. A significant linear correlation was apparent between HNE and TBARS for the pork stored at each temperature. However, the n-6 PUFA content remained unchanged during storage.
