This study aimed to determine the effect of adding sonicated coconut shell liquid smoke to pekin duck jerky with different storage times at room temperature and vacuum packed. Ground duck jerky is made from Pekin duck meat (Anas platyrhynchos domesticus) soaked in coconut shell liquid smoke (CSLS) which has been sonicated for 20 minutes and seasoned with spices such as garlic, galangal, coriander, tamarind, salt, and coconut sugar. A laboratory experiment was done using a completely randomized design (CRD) consisting of 5 treatments (control: 0 day storage period, T1: 7 days, T2: 14 days, T3: 21 days, and T4: 28 days) and 4 replications. The results showed that the addition of sonicated CSLS with differences in the shelf life of pekin ground duck jerky had a significant effect (P<0.01) on pH, texture, color L, a*, b*, Aw, water content, fat, carbohydrates by difference, thiobarbituric acid (TBA), and iodine number. Had a significant effect (P<0.05) on ash content, and had no significant effect on Water Holding Capacity (WHC), protein content, and organoleptic quality. It was concluded that storing ground duck jerky for 14 days at room temperature and vacuum packed did not show any damage to pH, water activity, water content, fat, protein, TBA and iodine number, and did not occur rancidity.
