Hyper Pure Germanium (HPGe) radiation detector was used to estimate the activity concentration of fifteen soil and palm oil samples collected from the oil palm plantations in the southwestern, southeastern, and south southern states of Nigeria, and the risk assessments was evaluated. The activity concentrations at a soil depth 0 – 15 cm ranged from 187.4 to 514.4, 2.328 to 6.571, and 1.509 to 6.121 Bq/kg for 40K, 238U, and 232Th, respectively. The activity concentrations at a soil depth 15 – 30 cm ranged from 163.4 to 3188.8, 1.345 to 9.410, and 1.476 to 6.275 Bq/kg for 40K, 238U, and 232Th, respectively. The activity concentrations in the palm oil ranged from 122.3 to 968.0, 1.240 to 6.651, and 1.199 to 8.061 Bq/L for 40K, 238U, and 232Th. For the risk assessments of surface soil samples, the absorbed dose rate (D) ranged from 5.09 to 24.54 nGy/h, while the annual effective dose equivalent (E) ranged from 0.612 × 10-2 to 16.49 × 10-2 mSv/y. The radium equivalent, gamma absorbed dose rate, and the annual effective dose rate in the palm oil samples ranged from 9.981 to 88.00 Bq/L, 4.315 to 46.29 nGy/h, and 0.53 × 10-2 to 56.90 x 10-2 mSv/y, respectively. The activity concentrations reported for soil and palm oil samples were lower than the recommended world average values given by UNSCEAR. Hence, the hazard and risk assessments indicated a low radiation risk within the studied areas.

“…More recently, the quality and safety of palm oil is once again questioned. There are sometimes unfounded claims that presence of non-essential trace elements in palm oil reduces its nutritional benefits (Olafisoye et al, 2015). The case in point is the recent negative press on the presence of 3-MCPD and glycidyl esters (GE) in palm oil.…”

Arriving at this milestone after an illustrious century, the growth from an ornamental palm to a multibillion dollar commodity crop in Malaysia has been a remarkable journey for oil palm. From its humble beginnings in Malaya as a monoculture plantation crop in 1917, it has grown to occupy over 5.7 million hectares of land space by 2016, demonstrating the impact the crop has had on the country's economy over the last 100 years. Its importance has led to many initiatives being implemented with a concerted effort to effectively develop and safeguard the posterity of the industry. In treasuring the past, engaging the present and charting the future, this review reflects briefly on the direction the industry has taken to reach this present state. The foresightedness of early players in the industry has helped thrust the industry forward by systematically building a rich resource within the country. As the industry matures, it is only natural for challenges to surface and there is a constant drive to manage public perception and to stay sustainable in order to remain competitive. In this respect, oil palm has followed in the footsteps of other crops in decoding its genome and simultaneously answering some long-standing questions about the biology of the oil palm. Efforts have also been devoted to automate and mechanise the industry as a solution to address the labour supply issue. Midstream and downstream sectors have experienced similar transformations in their operations as well. Essentially, the employment of these so-called transformative technologies which are the essence of the 4 th Industrial Revolution are comparatively still at its infancy for this industry. However, as precision agriculture gains prominence and in keeping to Malaysia's 2050 national transformation aspirations, we envisage that these disruptive technologies will be the driver of innovations in all sectors, especially oil palm.

“…The fruit is the oil-producing organ of oil palm and the vegetable oil extracted from the mesocarp and kernel is known as palm oil (PO) and palm kernel oil (PKO), respectively ( Dussert et al., 2013 ).The mesocarp and the kernel of oil palm make this crop unique and economically important due to their extraordinarily high oil contents (approximately 85% and 50% dry mass, respectively). PO has excellent characteristics such as high nutritional and oxidative stability ( Olafisoye et al., 2015 ; Kadandale et al., 2019 ). It is low in sterols, rich in vitamin A and vitamin E, and contains 50% saturated fatty acids, 40% monounsaturated fatty acids, and 10% polyunsaturated fatty acids ( Clegg, 1973 ; Manorama and Rukmini, 1991 ; Boateng et al., 2016 ).…”

IntroductionOil palm is the world's highest yielding oil crop and its palm oil has high nutritional value, making it an oilseed plant with important economic value and application prospects. After picking, oil palm fruits exposed to air will gradually become soft and accelerate the process of fatty acid rancidity, which will not only affect their flavor and nutritional value, but also produce substances harmful to the human body. As a result, studying the dynamic change pattern of free fatty acids and important fatty acid metabolism-related regulatory genes during oil palm fatty acid rancidity can provide a theoretical basis for improving palm oil quality and extending its shelf life.MethodsThe fruit of two shell types of oil palm, Pisifera (MP) and Tenera (MT), were used to study the changes of fruit souring at different times points of postharvesting, combined with LC-MS/MS metabolomics and RNA-seq transcriptomics techniques to analyze the dynamic changes of free fatty acids during fruit rancidity, and to find out the key enzyme genes and proteins in the process of free fatty acid synthesis and degradation according to metabolic pathways.Results and discussionMetabolomic study revealed that there were 9 different types of free fatty acids at 0 hours of postharvest, 12 different types of free fatty acids at 24 hours of postharvest, and 8 different types of free fatty acids at 36 hours of postharvest. Transcriptomic research revealed substantial changes in gene expression between the three harvest phases of MT and MP. Combined metabolomics and transcriptomics analysis results show that the expression of SDR, FATA, FATB and MFP four key enzyme genes and enzyme proteins in the rancidity of free fatty acids are significantly correlated with Palmitic acid, Stearic acid, Myristic acid and Palmitoleic acid in oil palm fruit. In terms of binding gene expression, the expression of FATA gene and MFP protein in MT and MP was consistent, and both were expressed higher in MP. FATB fluctuates unevenly in MT and MP, with the level of expression growing steadily in MT and decreasing in MP before increasing. The amount of SDR gene expression varies in opposite directions in both shell types. The above findings suggest that these four enzyme genes and enzyme proteins may play an important role in regulating fatty acid rancidity and are the key enzyme genes and enzyme proteins that cause differences in fatty acid rancidity between MT and MP and other fruit shell types. Additionally, differential metabolite and differentially expressed genes were present in the three postharvest times of MT and MP fruits, with the difference occurring 24 hours postharvest being the most notable. As a result, 24 hours postharvest revealed the most obvious difference in fatty acid tranquility between MT and MP shell types of oil palm. The results from this study offer a theoretical underpinning for the gene mining of fatty acid rancidity of various oil palm fruit shell types and the enhancement of oilseed palm acid-resistant germplasm cultivation using molecular biology methods.
