“…The main reason for the increased cultivation of O Â G cultivars in Colombia is that some of these cultivars have some degree of resistance to bud rot (BR) (Navia et al, 2014;Ávila-Diazgranados et al, 2016), the most serious disease affecting oil palm crops in Latin America (Torres et al, 2016;Swinburne, 1993). The oil extracted from O Â G has gained prominence in the production of goods for human consumption along the past decade because it has high concentrations of oleic acid, tocotrienols, and phytonutrients, which entail cardioprotective, antioxidant, and anti-inflammatory benefits (Mozzon et al, 2018;González-Diaz et al, 2021).…”

Oil palm interspecific hybrids Elaeis oleífera × Elaeis guineensis (O × G) are grown across approximately 68,000 hectares in Colombia. To address the limited natural pollination capacity of O × G hybrids and the difficulties associated with assisted pollination regarding the timing of E. guineensis pollen application, the Colombian Oil Palm Research Center (Cenipalma) conducted studies on induction of parthenocarpic fruits. Cenipalma confirmed that application of 1,200 ppm of 1-naphthaleneacetic acid (NAA) at different phenological stages enabled the formation of parthenocarpic fruits. This technological advance was termed artificial pollination. This paper presents the results from a research study aimed at assessing the labor productivity for two methods of NAA application (NAA in solid mixture and NAA in liquid suspension). From a methodological standpoint, a time and motion study was conducted to assess labor productivity for each NAA application method, with time data collected using the software Cybertracker on a mobile platform (smartphone). The results indicated that a worker can cover 3.9 hectares in a working day and sprinkle 303 inflorescences in a working day when applying NAA in solid mixture. On the other hand, when applying NAA in liquid suspension, the worker can cover 3.2 hectares and sprinkle 315 inflorescences (i.e. in a working day).

“…Virgin palm oil (VPO) is a phytonutrient-rich palm oil that can be applied as food ingredients, pharmaceuticals, and cosmetics [6,14]. Generally, VPO is the improved version of palm oil and contains vitamin E, phytosterols, carotenoids, phenolic, medium-chain fatty acids, and water-soluble antioxidants [14]. Despite the wide application of palm oil in various products application, the production and uses of VPO in food, pharmaceutical, and cosmetics production are not well-known because of the lack of exposure to the functional properties of VPO, its usability, and health benefits.…”

Palm oil is known to be rich in carotenoids and other phytonutrients. However, the carotenoids and phytonutrients degrade due to high heat sterilization of oil palm fruits. The present study was conducted to produce carotenoid-rich virgin palm oil (VPO) using cold-press extraction. Herein, the influence of sterilization of oil palm fresh fruits in the production of cold-pressed VPO was determined with varying sterilization temperatures, times, and amounts of palm fruits in sterilization. The experimental sterilization conditions were optimized using response surface methodology (RSM) based on the maximum VPO yield and minimum FFAs in cold-pressed VPO. The optimal sterilization experimental conditions of oil palm fruits were determined to be a sterilization temperature of 62 °C, a time of 90 min, and an amount of oil palm fruits of 8 kg. Under these experimental conditions, the maximum cold-pressed VPO yield and the minimal content of free fatty acids (FFAs) obtained were 27.94 wt.% and 1.32 wt.%, respectively. Several analytic methods were employed to determine cold-pressed VPO quality and fatty acids compositions and compared with the crude palm oil. It was found that cold-pressed VPO contains higher carotenoids (708 mg/g) and unsaturated fatty acids compared with the carotenoid (343 mg/g) and fatty acid compositions in CPO. The findings of the present study reveal that the sterilization temperature potentially influences the carotenoid and nutrient contents in VPO; therefore, the optimization of the sterilization conditions is crucial to producing carotenoid- and phytonutrient-rich VPO.

“…Because of their ability to scavenge free radicals in the environment, antioxidants such as carotenes, tocopherols, tocotrienols and ubiquinones are highly reactive compounds, which bring about the possibility that one or more of these compounds may be depleted with time during processing and storage when exposed to different conditions. Heat is the catalyst for the formation of free radicals leading to higher losses of these antioxidant vitamins ( Teh and Lau, 2020 , Gonzalez-Diaz et al, 2021 ).…”

“…increases our requirements for these antioxidant phytonutrients. Consumption of foods rich in these antioxidant vitamins would, therefore, provide health benefits to the consumers ( Idris et al, 2014 , Gonzalez-Diaz et al, 2021 ). The presence of this natural vitamin E in palm oil ensures a longer shelf life for palm-oil-based food products ( Meng et al, 2020 ).…”

The objective of this research work was to produce acceptable quality functional foods, namely, extruded snacks, digestive biscuits and pan bread, on a pilot scale, using vitamin E and β-carotene-rich red palm olein (RPOL) and red palm shortening (RPS). These products were evaluated for their chemical composition and sensory quality along with the antioxidants and vitamin contents during the six months of storage at room temperature (22 ± 1 °C). Extruded snacks and digestive biscuits prepared with RPOL and RPS were found to be good sources of these antioxidant vitamins. The average β-carotene content of the control and test snacks at the end of six months of storage ranged from 26.8 to 56.1 mg/kg fat, and from 430.9 to 468.9 mg/kg fat, respectively. The total vitamin E content in control and test snacks made in Plant No. 1 decreased after six months of storage from 786.1 to 704.4 mg/kg fat, and from 765.1 to 695.4 mg/kg fat, respectively. As expected, the total tocotrienol content was four to five times higher than the total tocopherols in control biscuits. The RPOL containing 600–750 ppm of carotenes (mainly α- and β-carotenes), 710–774 ppm of vitamin E, was found to be suitable for industrial application in producing acceptable quality pan bread, digestive biscuits and snacks. These functional foods contained significant amounts of β-carotene and total vitamin E, indicating the possibility of producing such foods rich in these two of the important antioxidant vitamins coming from a natural source. The research findings strongly indicate that good-quality pan bread, extruded snacks and digestive biscuits can successfully be produced to offer healthier eating choices to the consumers of this region, thereby promoting better health and productivity among the population.
