Emulsion-type sausages were manufactured to investigate the effects of CLA-vegetable oils and CLA-lard on quality of emulsion-type sausage. Each treatments replaced pork back fat with CLA-sesame oil (CLA-SO), CLA-lard (CLA-LD) and CLA-safflower seed oil (CLA-SSO) were stored during 1, 7, 14, 21 and 28 days at 4$^{\circ}C$. The changes in physico-chemical properties, thiobarbituric acid reactive substances(TBARS) and fatty acid composition of each treatments were measured during 1, 7, 14, 21 and 28 days at 4$^{\circ}C$. The pH values of all treatments significantly(p<0.05) decreased as storage time increased. Sausage products containing CLA-vegetable oils showed higher pH value than that of CLA-lard among the treatments. Color a*-value of CLA-SSO was higher than that of other treatments. During storage, TBARS values of treatments were significantly (p<0.05) increased, sausage products containing CLA-vegetable oils showed lower (p<0.05) TBARS value than CLA-lard, and TBARS of sausage products containing CLA-SSO was the lowest. This result indicated that CLA concentration in emulsion-type sausage did affect the lipid oxidation stability. Fatty acids composition was changed by addition of CLA-vegetable oils and CLA-lard. All kinds of fatty acids content decreased whereas CLA content extremely increased by replacement of CLA-vegetable oils and CLA-lard. The level of CLA content in CLA-vegetable oils was higher than CLA-lard. It may be concluded that emulsion-type sausage could be manufactured using CLA-vegetable oils as a pork fat substitutor without any negative effects on general components or physico-chemical properties.
