This study was carried out to evaluate the phsicochemical, rheological and sensory characteristics of the restructured pork jerky with the addition of sliced cheese(4, 8 and 12%). The TC-1, TC-2 and TC-3 samples had lower moisture contents than the control, Crude protein and fat contents were significantly difference among all treatment (p<0.05). The crude ash and salinity values of TC-1, TC-2 and TC-3 were higher than the control. With the addition of sliced cheese(l2%), the manufacturing yield and water absorption ability were high among all the different treatments, but the control showed significantly higher values than TC-1, TC-2 and TC-3. The pH ranged from 5.62-6.01 in all treatments and the TC-3 sample had the highest pH, The water activity range was 0.70 - 0.74, and the various treatments had slightly higher than the control. The hardness of the TC-3( J 2%) treatment was the lowest among all the treatment. The strength values increased according to increases in sliced cheese, but there were no significant differences(p>0.05). The sensory evaluation for color and flavor received the highest scores in working males 6.96(TC-2) and student males 7.50(TC-2), respectively. The texture scores ranged from 7.07-7.63 and were the highest of all sensory evaluation factors, For overall acceptance the highest scores were received from student males(TC-3), student females(TC-2), working males(TC-2) and working females(TC-l), respectively.
