“…As reported by [1], this value is slightly higher than that of sunflower seeds (3%). Also, it was found that Moringa seed has higher ash content than groundnut as reported by [12], who found the range of 2.2% to 2.5% for three groundnut seeds.…”

Moringa stenopetala, locally known as Shiferraw, is an indigenous vegetable tree native to southern Ethiopia and grown mainly for its food value. This study deals with the investigations of physicochemical characteristics of Moringa stenopetala seeds’ oil extracted using solvent extraction with food-grade hexane as a solvent and Analysis of Variance (ANOVA) of the extraction parameters. The seeds were collected from Adama located in Oromia, East Shewa Zone of Ethiopia, and they exhibit the average moisture, ash, fiber, protein, and oil contents of 6.3, 4.2, 2.3, 27.5, and 40.2%, respectively. Temperature, extraction time, and particle size had a significant p < 0.05 effect on the oil yield. According to the Experimental Design Response Surface Methodology (RSM) and ANOVA analysis, the optimum process parameters’ combination to find the highest oil yield was particle size of 0.83 mm, the temperature at 78.82°C, and extraction time of 5.13 hours. The model predicted oil yield was 39.7 ± 0.32%. The oil from Moringa stenopetala seed exhibits physiochemical characteristics of refractive index (40°C), 1.4625; viscosity 49.4 Cp; density at 25 °C, 0.9317 g/cm−3; saponification value, 191.4; peroxide value, 11.52 millieq O2/kg; iodine value of 89.21; and Acid Value (AV) 2.21 mg KOH/g. Fourier-transform infrared spectroscopy (FT-IR) analysis shows that the oil contains both ester carbonyl (C=O) functional groups saturated and unsaturated fatty acid. The physicochemical properties of Moringa stenopetala seeds were compared with other edible oil properties such as sesame, groundnut, olive, and sunflower seeds. The result shows that in the future Moringa stenopetala could be used as a substitute for other oil-bearing seeds sources, such as soybean, sunflower, and groundnut.

The increasing use of composite components in various engineering disciplines necessitates detailed comprehension of their operation. When subjected to adverse environmental circumstances, such as variable humid surroundings and UV radiations, the structural and mechanical characteristics of the composites can deteriorate. Additionally, using these composite materials for structural applications such as rooftop buildings or household properties may reduce lifespan. In this study, the static and dynamic mechanical properties and the stability of novel lignocellulosic Moringa stenopetala (MS) husk fiber‐based epoxy composites exposed to various environmental factors were assessed. These harsh conditions were picked to imitate those encountered outside and influence the longevity of these composites. The obtained fiber from the husk was examined for its physiological, structural, and thermal characteristics. Using the Broido, Kissinger, Flynn‐Wall‐Ozawa (FWO), Coats‐Redfern and Kissinger‐Akahira‐Sunose (KAS) isoconventional models, the thermal degradation kinetics of the fibers were investigated. KAS method results in the best‐fitted curve and shows maximum activation energy of 175.13 KJ/mol. After husk fiber assessment, composite materials were fabricated using a Hand layup method, and their static and dynamic mechanical properties, water uptake rate, and contact angle analysis with surface energy behavior under various environmental aging circumstances were studied. In comparison to the composites “as developed,” the findings indicate that the mechanical characteristics of husk fiber‐based epoxy composites are significantly reduced by humidity and UV aging. Overall, the development of thermoset composites for structural applications can utilize husk fiber. Furthermore, after curing the water and UV‐aged composites, qualities can be recovered.

The physical properties of groundnut seeds were calculated as a function of moisture content. The average length, breadth and thickness of the seed various from 13.09 to 14.10, 8.68 to 9.56 and 7.07 to 7.82 mm, respectively. As the moisture content, increased from 8.13 to 79.80% d.b. the roundness and sphericity increased from 92% to 94% and 68% to 71%, respectively. Also the seed volume increased from 0.803 to 0.984 cm3, 1000 seed weight, W1000 from 328 to 380 g, the angle of repose from 32.620 to 36.50 and the bulk density decreased from 0.845 to 0.81 g cm-3 for the same range of moisture content. The static coefficient of friction increased on three structural surfaces namely, stainless steel (2.013-2.32), aluminum (2.47-2.62) and wooden (2.25-2.42) as the moisture content increased from 8.13 to 79.80% d.b.
