The aim of this study is to characterize the different olive oil producing varieties produced in Ghabir Valley, Kalar Kahar For this purpose physical, chemical & orgnoleptic testing were performed & compared with international standards. Olive oil samples were tested on different parameter that included Refractive index, free fatty acid value, peroxide value, iodine value, Saponification numbers, Phenolic content & fatty acid profiling. In addition to characterize olive oil samples, olive leaves were dried up to certain temperature and conditions that can be used for traditional olive kehwa. Olive leaves are excellent source of oleuropein best known for its blood pressure-lowering effect. Olive dried leaves of same varieties were test for their Carbohydrates, protein, fat content, moisture content & ash contents. Among all olive varieties Pendolino oil & dried leaves have shown batter result in sense of shelf life stability, clarity, nutritive value & medicinal values. Olive extracts & olive pickles can be further developed as these products may have highly nutritional value & commercial outcomes.
