The meat dried in the oven after treated with some additives divided into four treatments: control treatment1(without additions) , treatment2 (Soya Sauce added) , treatment3 (special spices added) , treatment4(sweet chili sauce added). The moisture and protein percentage of jerky pieces were measured then panel test was conducted by specialized professors in the department .The results showed a significant differences in moisture contents between four treatments where the percentage was low in the third treatment than the others (23.45±0.45)% also the control treatment which was (25.16 ±0.22) %. protein percentage, the results indicated that there was a significant decreased in the protein percentage for treatment 2 and 4 which were (64.94±0.28)% and (65.02±0.74)% respectively .while this percentage was increased significantly in1 and 3 treatments ( 67.02±0.33)% and (68.52±0.11)% respectively.For the PH value, the results indicated that there was a significant decreased in the pH value for treatments 2,3 and 4 (5.66±0.04)(5.59±0.00)(5.71±0.01) compared to the control treatment which was (5.93±0.03).For the panel test, the results indicated that there was no significant differences in rancidity except accounting differences only where treatment 4 was superior than the other treatments . as for the color, treatment 2,3 and 4 showed significant differences for the desired color of the Jerky by the consumer as it reached (4.11±0.63) (4.74±0.17) and (4.90±0.62) respectively compared to the treatment 1 (3.12 ± 0.22). For the tenderness, there was no significant differences between the four treatments where the tenderness was decreased for all treatments.Finally, for the general acceptance, treatment 1 and 3 were superior as it reached (4.94±0.71)(5.00±0.65) respectively compared to treatment 2 and 4 as it reached (3.11±0/61)(4.28±0.58).
