Chlorpyrifos is a Malaysian Pesticide Board‐approved organophosphate insecticide, which may become concentrated during fractionation. The objective of this project was to develop and validate a method to detect and quantify chlorpyrifos in food‐grade fatty acids ingredients, e.g. caprylic‐capric acid mixture and oleic acid (OLA) used to synthesize triacylglyceride based food additives and in the cosmetic industry. A selective ion monitoring gas chromatography–mass spectrometry method with a matrix‐matched calibration curve calibration was selected. The method involved the direct injection of chlorpyrifos spiked into the fatty acids matrix. The percentage recoveries at spiking levels of 0.5, 0.75, 2.5, and 4.0 μg g−1 of chlorpyrifos in OLA and caprylic‐capric acid ranged from 85.7%–101.1% to 97.2%–112%, respectively, with a relative standard deviation of within 11%. The intra‐day and inter‐day precision were deemed acceptable as indicated by an relative SD value of within 10%. A good linear relationship with a coefficient of correlation >0.99 for the matrix‐matched calibration was achieved between 0.5 and 5 μg g−1. The limit of detection and limit of quantification corresponded to 0.5 μg g−1 for OLA and 0.55 μg g−1 for caprylic‐capric acid.

“…The oil palm industry is the single largest contributor of biomass resources in Malaysia, amounting to 90% of the country's total lignocellulosic biomass [5,6]. The oil palm lignocellulosic biomass is mainly generated from 5.90 million hectares of oil palm planted areas and 452 palm oil mills nationwide [7]. Assuming that the mean weight ratio of mesocarp bre, palm kernel shell and empty fruit bunches (EFB) to fresh fruit bunches (FFB) is 13%, 6% and 23% [8,9] respectively, the estimated total solid biomass production from the palm oil milling sector alone was 40.3 million t (wet basis) based on 98.28 million t FFB processed in 2019 [10].…”

Fuel quality is among the major issues encountered for commercial production and utilisation of oil palm-based biomass pellets from empty fruit bunches (EFB). In this study, a physical treatment, namely sieving and water washing, was applied to EFB prior to densification using an industrial-scale plant. The physiochemical properties of the produced EFB pellets were compared with those without physical treatment as the control. The results showed that the physical treatment process had significantly enhanced the fuel properties of EFB pellets, particularly in reducing ash content. Both the treatments; sieving alone and a combined sieving and water washing of the feedstock managed to reduce the ash content of EFB pellets to < 4 wt.% and < 2 wt.%, respectively compared to > 5 wt.% of typical commercial EFB pellets. The reduction in ash content improved the calorific value of pellets to > 17.5 MJ kg-1 which signified achieving a milestone for oil palm biomass-based heat and power generation from technical, operational, economic and environmental points of view. The findings also indicated that the combined sieving and water washing treatment method could potentially reduce further the unwanted ash-inducing elementals in EFB pellets, in particular chlorine and potassium. This study demonstrated that the employed physical treatment is an immediate and cost-effective practical commercial approach to improve the fuel properties of EFB pellets.

“…is an important oil crop which supplies 35% of the global vegetable oils and fats [1]. Currently, oil palms have an economic life exceeding 20 years and can produce 10 times more oil per hectare than other oil crops [2]. One of the contributing factors to current yields is the switch in the 1960s of commercial dura planting to dura x pisifera hybrids (DxP), also termed tenera.…”

Ethephon-Induced Abscission of Oil Palm Fruits at Optimal Bunch Ripeness and Retting Period to Improve Commercial Seed Production

Oil palm seed producers typically require 10 months of various processes from pollination to seed germination to produce commercial dura × pisifera hybrid seeds. Conventional forced fruit shedding from underripe fresh fruit bunches (FFB) usually causes seed damage and an extended retting period (incubation for natural fruit abscission from spikelets), eventually leading to bunch rot and disease infection. As a fruit ripening agent, ethephon has been explored to hasten fruit abscission in many fruit crops and oil palm. Nevertheless, the previous studies in oil palm only focused on fruit shedding from FFB to improve oil extraction rate in oil mills without considering the actual FFB ripeness and retting period, which are critical for oil palm seed production. In this study, the application of ethephon containing buffer (adjusted to pH 9.0) to underripe FFB at 145 days after pollination (DAP), 135 DAP and 125 DAP resulted in 50% more fruit abscission after a 72-h incubation. Considering the minimal seed loss upon FFB harvest (<1%) and 50% reduction in retting period, underripe FFB at around 145 DAP was found to be optimum for seed production using ethephon treatment. The treatment, however, made negligible improvement in fruit detachment for ripe FFB at 150 DAP and older. Importantly, seed germination and culling rate at nursery stages were not significantly affected by the ethephon treatment. Hence, ethephon application can improve commercial seed production practices for oil palm.
