... differences are likely because of different moisture contents and different size composition of the experimental samples. Table 3 shows the measured physical properties of Mucuna pruriens (Ukpo) seed at average moisture content of 11.39 AE 0.82% db. Ukpo seed has a mean length, width, and thickness of 28.4 AE 1.6 mm, 28.1 AE 1.8 mm, and 19.4 AE 1.8 respectively. ...

... Bulk densities, coefficients of friction on some commonly used material surfaces (galvanized steel, plywood, glass, plastic, and concrete), and angles of repose of crops are all needed for the development of handling and storage machinery (Parde et al., 2003). These properties are also necessary for predicting the load and pressure on storage structures, as well as designing grain hoppers for processing equipment (Asoiro et al., 2020). ...

In this study, the effect of moisture content on the physical attributes of baobab seeds was examined, along with the implications for the design of machinery for postharvest handling and processing of the seeds. The seed's volume, sphericity, aspect ratio, axial dimensions, arithmetic, and geometric mean diameters were all determined. Gravimetric properties including porosity, bulk density, and thousand grain mass were measured. Additionally, the seeds' frictional characteristics on different surfaces for handling after harvest were established. The arithmetic and geometric mean diameters were found to be in a range of 8.00 and 9.64 mm and 7.86 and 9.50 mm, respectively, with moisture contents between 5.4 and 20.6% on a dry basis. The seed's sphericity ranged from 78.18 to 80.38 percent. Densities for the bulk and particle ranged from 740.77 to 763.40 kg/m 3 and 1155.22 to 1223-29 kg/m 3 , respectively. The study revealed that among the four frictional surfaces, plywood surface had the greatest resistance to the flow of the seeds, and the least was registered for the glass surface material. The effect of moisture content on the seed's physical properties were statistically significant (p≤0.05). Regression equations for future predicting the various physical properties at different moisture contents were developed. The study has produced valuable information that will help with the design of machinery for handling and processing baobab seeds after harvest.

... The effect of storage on the quality of the polymer [14], improvement of its shelf life [15] and modeling of its drying characteristics [16] have been investigated. Studies on the physical, chemical and biochemical properties of Irvingia gabonensis have been reported [17,18,19,20]. All of these show that Irvingia gabonensis polymer has been extensively studied in isolation and there is vast knowledge about its applications, properties, synthesis and nutritional value. ...
... Traditionally, the pulp of this fruit is eaten fresh and the seeds are used as a food additive, and as such possess superb economic and nutritional advantages [7]. They are good sources of phytochemicals including the likes of alkaloids, flavonoids, saponins, tannins, and glycosides, as well as proteins, minerals, vitamins, carbohydrates, fats, and soluble fibres [8]. Studies have shown that Irvingia gabonensis pulp extract possesses therapeutic potentials which are beneficial, including but not limited to weight loss [3] and antioxidant activity [9]. ...

This study evaluates the medicinal and therapeutic importance of aqueous pulp extract of Irvingia gabonensis (APEIG) fruit on some biochemical indices in adult male albino rats. Thirty-six adult male rats were grouped into 3 groups of 12 rats each. Group 1 was the control, while groups 2 and 3 received 100 and 200 mg/kg body weight of the extract respectively. The quantitative and qualitative phytochemical constituents present in the APEIG were alkaloids, flavonoids, and terpenoids in moderate amounts, while saponins, tannins, glycosides, sterols, and phenols were detected in trace amounts. The treatment lasted for 21 days and biochemical parameters were analyzed following standard procedures. Results obtained indicated a reduction in the bodyweight of the treated groups. The serum cholesterol, LDL, and VLDL concentrations were significantly moderated in the treatment groups, although, the serum HDL concentration was elevated dose-dependently on days 14 and 21. Alkaline phosphatase (ALP) was elevated in the treatment groups on days 7 and 14 while aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine, urea, uric acid, total protein, and albumin were not affected by the administration of (APEIG) on days 7, 14 and 21. Serum bilirubin was significantly lowered in the treatment groups on days 7, 14, and 21 while fasting blood glucose (FBS) of the treated groups was moderate. The results revealed that the administration of APEIG had promising medicinal potentials and could be harnessed in disease management.
... 5 Nevertheless, there is greater utilization of the kernel, hence, it is a common practice to split the fruit into two using cutlass, in other to remove the split cotyledon (kernel) with knife, after which the flashy mesocarp is discarded, while the kernel is used for number of purposes. 9 Over the years, researches on I gabonensis kernel (IGK) majorly have been on its nutritional and medicinal applications, as well as the used of the milled kernels as condiment in soup as thickener, due to its rich fat and protein content. [10][11][12] Medicinally, it is used in body weight reduction of obese persons. ...

The effects of the temperature, time, and particle size, in addition to the kinet-ics and thermodynamics parameters, of Irvingia gabonensis kernel oil (IGKO) yield were investigated. The highest oil yield of 68.80% (by weight) was obtained at 55 • C, 150 minutes, and 0.5 mm. The evaluated physicochemical properties of IGKO indicated that viscosity, acidity, dielectric strength, flash, and pour points were 19.37 mm 2 s −1 , 5.18 mg KOH g −1 , 25.83 kV, 285 • C, and 17 • C, respectively, suggesting its feasibility as transformer fluid upon further treatments. Between the pseudo-second order and hyperbolic kinetic models studied, the former best describes the experimental data. ΔH, ΔS, and ΔG values of IGKO extraction at 0.5 mm and 328 K were, 251.81 kJ mol −1 , 1.08 kJ mol −1 , and −105.49 kJ mol −1 , respectively, indicating the endothermic, irreversible, and spontaneous nature of the process. The kinetic model equations that describe the process were successfully developed for both models based on the process parameters. K E Y W O R D S

Engineering properties of pearl millet varieties (Pusa composite 443, Pusa composite 701, Pusa1201 and Pusa1801) were evaluated at varying moisture content (10-25% wb). A significant varietal difference was found on studied properties. GMD, Surface area, thousand grain mass, the angle of repose, porosity, internal coefficient of friction, static coefficient of friction (Poly, GI, MS and Al) increased linearly with increase in moisture content within the range of 10 to 25% (w.b.) while the bulk density, true density and hardness decreased linearly with increase in moisture content within the same range. But the value of sphericity showed that direct and indirect relation with moisture content depending variety. The mean value of different cultivars observed and found extreme high and low value of bulk density, true density and porosity for PC701 and Pusa1201, geometric mean diameter and surface area for pusa1801 to Pusa1201, sphericity and internal coefficient of friction for Pusa1201 and PC443, grain mass for Pusa1801 and PC 701, angle of repose for Pusa1201 and PC701, hardness for PC701 and PC443 respectively at moisture ranges from 10 to 25% (wb).
