Tomato pomace supplementation didn’t significantly improve the color content of fatty acids, cholesterol and lipid oxidation and didn’t allow the incorporation of lycopene and β-carotene in meat. However, an increased content of α-tocopherol in muscle, liver and blood plasma and food intake in ad libitum phase of pigs. The type of fat influenced the fatty acid profile which soybean oil increased MUFA and PUFA and decreases the SFA. In sum, it was not possible to prove the effectiveness of the addition of 5% tomato pomace on nutritional parameters of pork meat. But there was a nutritional improvement on the lipids meat with soybean oil comparing to the lard.
