Forty-eight female piglets were raised with four levels of a-linolenic acid (0, 1.5, 2.5, 3.5%) to determine the effect of dietary fat on the fatty acid composition, sensory and storage stability of pork products. The degree of polyunsaturation in neutral lipids and phospholipids were increased significantly by the dietary LNA. R e thiobarbituric acid reactive substances (TBARS) values offeshly prepared brewast sausages with vacuum packaging remained low, but those of the loosely packaged, i. e., nonvacuumized, sausages increased more than 3 times during the 48 h storage period. The TBARS values of break$ust sausages frozen-stored for 3 months showed extensive lipid oxidation. The dietary LNA treatments andpackaging had significant effects on the susceptibility of breakjast sausages to lipid oxidation. However, the oxidative stability of cured products was not affected by the dietary treatments. The results indicated that the pork enriched with polyunsaturated fatty acids could be used in cured products or uncured meat products protected by 'hot vacuum packaging' without any sensory or quality deterioration due to lipid oxidation.
