In this study, olive oil producing, processing and intermediary enterprises in the TR22 Region in the 2017-18 production year were examined. As a result of the study, it was found that oil mills, olive oil factories, traders, retailers, TARİŞ and final consumers form the marketing channels in olive oil and olive oil in the research region. It was found that the waiting of oil grain olives as a result of agglomeration in post-harvest processing centers, the use of sacks in the transportation of oil grain olives, the mixing of bottom olives with the ones plucked from the branch and the use of poles in harvesting were found to reduce the efficiency. It has been found that increasing the olive paste temperature above the optimum level, opening the lid of the malaxer machine during kneading, and the emergence of the black water problem as a result of the use of three-phase and classical systems are the factors that reduce the marketing efficiency in the processing service. It was found that the marketing margin of the intermediaries was 1.64% in olive oil, 20.00% of traders in olive oil, 14.06% of factories and 22.58% of retailers. The difference between producer prices and retail prices was 51.16% for olive oil.
