“…Nonetheless, Pakistan has 5 million recently planted olive trees spread throughout 42,000 acres (17,000 hectares). This information was revealed by Muhammad Ramzan Anser, an agronomist and the deputy project director at CEFORT, on June 7, 2023, during the third annual "Olive Value Chain Conference" of Pakistan (S Ali et al 2024…”

To maintain the quality of extra virgin olive oil (EVOO), one important factor is to resist its oxidation during processing and storage. It is challenging task to prevent oxidation in EVOOs since various physical and chemical factors must be under control. In the present study extra virgin olive oil was stored under normal storage conditions for three months and monitored via quality parameters. A non-destructive fluorescence spectroscopy was performed to monitor the oxidation changes in EVOO from different olive growing regions of Pakistan and Al-Jouf region of the Kingdom of Saudi Arabia (KSA). Additionally, the impacts of geographic, climatic, and environmental factors on the oxidation of EVOOs were investigated. Two major changes in the fluorescence emission spectra of EVOO samples were mainly observed: a decrease in fluorescence emission intensities in the range between 500 to 600 nm, 650 to 690 nm, as well as a rise in the fluorescence emission intensities in the 365–500 nm region. These two changes were related to a degradation of beta carotene, chlorophyll content and formation of oxidation products. EVOO samples collected from Al-Jouf region, KSA showed low rate of oxidation which might be due to environmental and geographical effect, proper irrigation system, harvesting, processing and storage conditions. In a fast and non-destructive manner, The fluorescence spectroscopy successfully monitored the oxidation changes and deterioration of antioxidants in a rapid and non-destructive manner in the EVOOs.

This study aims at pomological characterizing of 09 olive cultivars planted in the field area of Barani Agricultural Research Institute (BARI), Chakwal to estimate genetic variability in Ottobratica, Hamdi, FS-17, Gerboi, Arbequina, Persia, Nabali, Koroneiki and Earlik. Following pomological traits: fruit and stone weight (g), fruit and stone size (cm), fruit and stone shape index (length/width) and flesh to stone ratio were studied. Data for studied traits were collected in 2019 according to the International olive council descriptor. A significant genetic difference was noticed in the morphological characteristics of both fruit and stone. Different pomological characters were expressed by each cultivar. A wide range of variation was noticed in fruit weight (1.33-5.57g), stone weight (0.20-0.63g) and flesh/stone ratio (0.90-4.96). Based on their fruit shape, studied cultivars were classified into two groups i.e., ovoid and elongate. However, no significant difference was recorded for the stone shape, as all the studied cultivars had the same elongated stone shape. Concerning the fruit size, high fruit size (4-6g) was observed in FS-17, Hamdi, Earlik and Persia whereas Koroneiki, Nabali and Gerboi had the smallest ones (>2g). Based on our results, Earlik, Hamdi and FS-17 are suggested to be more appropriate for table olive production. Thus, an evaluation of genetic diversity through this study can help in the varietal development of olive for table and oil purposes.
