Effect of Tomato Powder on Lipid Oxidation of Vacuum Packaged Chinese-Style Sausage
Abstract:
The parameters governing lipid oxidation of Chinese style sausages were evaluated by
investigating the changes in peroxide value and TBA during storage. In this research,
the conditions of added tomato powder (25 and 50 g tomato powder per kilogram
sausage) and storage temperature (30+-2, 40+-2 and 50+-2C) over the storage period of 4
weeks were varied. The results were compared with those of the control sample without
added tomato powder. According to the evolution of peroxide value and TBA, the
addition of 25 and 50 g tomato powder per kilogram sausage retarded the development
oflipid oxidation. Lipid oxidation kinetics of Chinese style sausages was found to be of
zero order with respect to both PV and TBA. The oxidation rates (kp v and kTBA)
decreased with an increase in the amount of tomato powder and increased with an
increase in the storage temperature. Activation energies of lipid oxidation in Chinese
style sausages (control, 25 and 50 g tomato powder per kilogram sausage) were
15.20+-8.64, 19.86+-7.82 and 21.14+-7.56 kcal mol" and 59.46+-1.41, 60.65+-1.1 0 and
62.00+-5.87 in the case of PV and TBA, respectively.
