| Outline of Final Research Achievements |
We investigate formation of trans fatty acid (TFA) in pork products such as ham and sausage, and control points to prevent formation of TFA in meat products. Higher amount of sodium nitrite added as a color coupler could be a catalyst that isomerizes unsaturated fatty acids in pork to TFA. The concentration of nitrite in pork was above 5 times higher than normal concentration to process meats. In addition, the effect of nitrite on TFA formation was enhanced by decreased pH of pork meat lower than 5.0. As the results of this study, both amount of nitrite and meat pH were critical control points to regulate the formation of TFA in pork products, and the product would be kept safe from risk caused by TFA if those points were appropriately controlled.
