Flavored paste was filled in glass jars covered with olive oil and stored for 180days at room temperature. Olive paste samples were analyzed for physicochemical properties and sensory evaluation.PH values of the pastes were ranged 3.20 to 4.30.There were significant difference between olive paste without addition and olive paste with basil after 180days of storage, on other hand the olive paste with dried tomatoes had no significant difference after storage.
