Nutritional and extractable oil profile in seeds of Sesamum indicum L. and Moringa oleifera Lam. were investigated using standard biochemical procedures. Proximate analysis revealed % crude protein contents of 24.32% in S. indicum while M. oleifera had 27.66%. Crude lipid contents were analyzed and 47.78% was obtained in S. indicum while 28.87% was obtained in M. oleifera. Crude carbohydrate analysis revealed S. indicum with 37.89% while in M. oleifera, it was 34.51%. Crude fibre obtained was 11.32% in S. indicum while 9.37% was identified in M. oleifera. Higher ash content of 9.13% was obtained in M. oleifera while 7.62% was obtained in S. indicum. Available energy (k/cal.) was analyzed in the samples with obtained values in S. indicum 692.22 k/cal. While M. oleifera had 545.91 k/cal. With significant difference (P=0.05) between the two species in terms of available energy (k/cal.). Results of extractable oil profile of S. indicum and M. oleifera revealed appreciable amounts of the oil with 54.65% found in S. indicum while M. oleifera had 39.33% with significant difference (P=0.05) between the two species. Physico-chemical properties of the seed oils analyzed include, acid value determined with 34.32 mg KOHg-1 for S. indicum and 29.98 mg KOHg-1 obtained in M. oleifera. Saponification value of the two samples indicated that S. indicum had 148.82 mg KOH/g while M. oleifera had 127.88 mg KOH/g. Kinematic viscosity was determined and S. indicum had 0.97 mm2/s while 0.78 mm2/s was identified in M. oleifera. Iodine value was determined and S. indicum had 128.56 g l2 /100 g while M. oleifera had 103.68 g l2/100 g. Specific gravity was determined with 0.89 g/cm3 obtained in S. indicum while 0.84 g/cm3 was obtained in M. oleifera. Cetane number was determined; S. indicum had 34.00 while 30.00 was obtained in M. oleifera. Oil colour was determined and the colour ranged from yellowish-brown to creamy-yellow for S. indicum and M. oleifera respectively with no significant difference (P=0.05) in iodine number, acid value, kinematic viscosity and cetane number. State of the oil at room temperature indicated that the oils from the two seed types are liquid at room temperature. Mineral analysis of the two samples indicated that they comprise of appreciable amounts of minerals with phosphorus 385.51±4.96 mg / 100 g obtained in M. oleifera while in S. indicum, 254.54±4.06 mg / 100 g was obtained. Calcium was richly obtained in the two samples with 95.20 mg / 100 g obtained in M. oleifera while 66.70 mg / 100 g was obtained in S. indicum. However, potassium, manganese, copper, and magnesium were appreciably contained in the seeds with significant difference (P=0.05) between the two samples. Thus, it can be recommended that seeds of M. oleifera especially and that of S. indicum should be properly incorporated in the diets especially in the developing countries where hunger and malnutrition ravage the growing children and pregnant women.

Increased energy consumption and climate change, driven by greenhouse gas emissions, pose significant risks to global sustainability. Concerns about using agricultural land for fuel production and its competition with food production have made feedstocks like corn (Zea mays) highly controversial. This study explores the potential of alternative feedstocks, such as hemp (Cannabis sativa) and cucurbits (family Cucurbitaceae), for biofuel production amidst environmental concerns linked to fossil fuel usage. Hemp is widely acknowledged as a promising feedstock for sustainable biorefinery due to its agricultural adaptability and its ability to produce oil and carbohydrates. Cucurbits seeds are characterized by a high oil content, which can be utilized in the food industry or for energy production as biofuel. As a byproduct of cucurbits processing, a significant number of seeds often remains, which constitutes waste. By examining hemp and cucurbit byproducts and waste, which are suitable for bioenergy production, this research highlights the promise these alternative feedstocks hold for the biofuel industry. Utilizing these resources presents a viable route to diminish dependence on fossil fuels and transition toward a more environmentally sustainable energy future.

“…Within the vast Cucurbitaceae botanical family, consisting of 125 genera and 960 species, several vegetables stand out for their significance (Karaye et al, 2021;Verdejo-Lucas and Talavera, 2019). Notable species like Cucurbita maxima, C. moschata, C. pepo, C. ficifolia, and C. argyrosperma are widely cultivated (Decker, 1988;Yoo et al, 2023).…”

This study focused on the impact of citric acid, hot water blanching, and ultrasound pretreatment on the drying of zucchini slices, color properties, and the comparison of artificial neural network (ANN) and thin-layer modeling. The pretreatments enhanced the drying rate and reduced drying time. Ultrasound pretreatment was observed as the most effective, with a reduction rate of the drying time as 40%. Besides, mass transfer and moisture diffusion phenomena were positively affected by pretreatments, depending on the increment of the drying rate. The highest mass transfer coefficient (hm), moisture diffusivity (D) by the Dincer and Dost model, and effective moisture diffusivity (Deff) by the Crank equation were obtained with ultrasound pretreatment. On the other hand, Midilli and Kucuk, Parabolic, and Page gave the best predictions among the thin-layer models. However, ANN modeling had a better performance than thin-layer modeling due to a higher determination coefficient (R2) and lower root mean square error (RMSE) values. Color properties of the zucchini slices were affected by drying processes. In general, the redness and yellowness of the zucchini slices increased; however, lightness did not show statistical significance. Additionally, citric acid pretreatment gave the lowest total color difference (∆E).
