This work aimed to characterize and compare the physicochemical, ascorbic acid, phenolic, and flavonoid compounds, as well as the antioxidant properties, pollen spectra, and sugar profiles of twenty-three organic honeys produced in the Middle Atlas of Morocco. As results, the pollen analysis showed 22 taxa and revealed the dominance of Ziziphus lotus pollens for all monofloral honeys. The moisture content ranged from 15.9 to 19.0%, pH values werebetween 3.9 and 4.8, electrical conductivity varied from 100 to 581 µs/cm, ash content varied from 0.1 to 2.4%, and the invertase activity ranged from 3.5 to 36 U/kg. Moreover, hydroxymethylfurfural(HMF) varied from 1.2 to 13.5 mg/kg, which confirmed the freshness of our honey samples. For the sugar profiles, there were no significant differences between the examined groups of honeys (p > 0.05) for both fructose and glucose. Additionally, our study showed good antioxidant properties (total antioxidant activity ranged from 34.18 to 131.20 mg AAE/g; DPPH IC50 values ranged from 8.14 to 45.20 mg/mL; ABTS IC50 values ranged from 8.19 to 32.76 mg/mL) and high amounts of phenolic compounds ranging between 20.92 ± 0.03 and 155.89 ± 0.03 mg GAE/100 g, respectively; flavonoid compounds ranged from 5.52 to 20.69 mg QE/100 g, and ascorbic acid ranged from 8.01 to 23.26 mg/100 g. Overall, the proximate composition and the general characterization of organic monofloral and polyfloral honeys as sustainable and health-promising functional products may increase their commercial values, promote their marketability, and might have a significant impact on the basic circular/sustainable economy as a solid lever for solidarity economic development, especially in the rural/poor Moroccan communities. The investigated features may allow and support the incorporation of Moroccan organic honeys and their biovaluable ingredients in the nutraceutical and food industries for multiple purposes.

Rapeseed (Brassica napus L.) is the world’s second-largest oilseed crop after soybean. It contains functional compounds, including fatty acids and phenols, which are known for their health and nutritional benefits. In Morocco, rapeseed was introduced as a promising oilseed crop that has shown good adaptation and great potential. Six genotypes were registered and released as the most high-performance Moroccan varieties in terms of both seed yield and oil content. Apart from their ‘00′ quality, i.e., oil without erucic acid and meal with very low glucosinolate content, there is no information on other important quality traits. Therefore, this research aimed to characterize the lipochemical and phenolic attributes of those varieties, namely Baraka, Narjisse, Moufida, Lila, Alia, and Adila, grown at two contrasting sites (Allal Tazi and Douyet) so as to assess the environmental impact on oil quality. A set of 14 parameters were analyzed, comprising seed yield, oil content (Oil C), protein content (PC), acidity index (IA), peroxide index (IP), refractive index (IR), iodine value (IO), total phenolic content (TPC), total flavonoids, total carotenoid contents, free-radical scavenging activity (FRSA), half-maximal inhibitory concentration, fatty acid composition, and omega 6/omega 3 ratio. The results displayed significant differences (p < 0.001) between the two sites for all the abovementioned traits, except for IA, with an outperformance of Allal Tazi over Douyet. Additionally, variety and variety by site interaction had a significant effect on all the studied parameters, except for IA, IP, IR, and TPC. Over both environments, the varietal effect generated variations in yield of 10.9 to 17.1 q/ha, Oil C of 36.7 to 39.9%, PC of 21.3 to 25.9%, IO of 94.1 to 100 g I2/100 g, FRSA of 22.7 to 42.9%, and an omega6/omega3 ratio of 1.8 to 2.3%. It is noteworthy that the Moufida and Alia varieties displayed a low-magnitude effect of the environment, as they maintained similar high performance over both sites. They, thus, represent Moroccan genetic material of interest from an agronomic and nutritional perspective. Therefore, they should be promoted and encouraged for cultivation in Morocco, mainly in the Allal Tazi area and similar regions.

This study aimed to screen 135 cultivars of fig (Ficus carica L.) to identify the most suitable cultivars in terms of morpho-agronomic and biochemical characters. The free radical scavenging activity was assessed through DPPH, ABTS and β-Carotene bleaching assays. The studied genotypes exhibited significant variability (p < .01) following all traits analyzed. The Canonical Correlation Analysis (CCA) revealed a significant relationship between biochemical components and morpho-agronomic traits of fig. With the exception of the drop at the ostiole, lenticel color, and seed sizes, all variables showed highly significant differences. All studied genotypes averaged the fruit weigh of 34.41 ± 14.78 g with a dominance of globose shape. Based on the principal component analysis, the most discriminant attributes were the fruit geometrical traits, color, and peel characteristics. Also, the total sugars (10.08–15.10 g/100 gdw), total anthocyanins (0,41 to 47.95 mg cy-3-rutinoside/100 gdw) and flavonoids (103,7 ± 8.9–14.6 ± 4.6 mg CE/100 gdw) contributed significantly in fig assessment. Unweighted pair group cluster analysis based on Euclidean distance revealed five distinct groups. The local genotype ‘Ounq Hmam PS14ʹ showed a typical profile and was classified as an independent branch. The findings confirmed the effectiveness of combining morpho-agronomic and biochemical analyses in fig assessment. They also showed that the studied fig germplasm has high phenotypic diversity, which is probably more genetically related. The studied accessions can be recognized as an important gene pool for future breeding programs.

Vegetable oils are crucial for the human diet, providing energy and essential fatty acids. This study investigates the formulation of a high-quality cold-pressed vegetable oil blend from rapeseed, sunflower, sesame, and safflower, chosen for their agronomic benefits, cost-effectiveness, and reduced environmental impact. For the first time, this study is carried out in order to enhance the nutritional profile of these blend oils compared to commercial oils. The study’s results showed that all formulated blend oils had higher total polyphenol and flavonoid content. Specifically, the blend of 1/2 rapeseed, 1/4 sunflower, 1/8 sesame, and 1/8 safflower had an oil yield ranging from 37 to 39% and was rich in total polyphenols (18 mg GAE/100 g), total flavonoids (2 mg/g), antioxidant activities (52%), oleic acid (46.4%), and saturated fatty acids (11%), with a balanced omega-6/omega-3 ratio (2.5). Consuming this blend oil offers a healthier choice rich in nutrients and natural antioxidants. This could open new market opportunities and cater to the growing demand for healthier oil options, especially since it is extracted without a refining process. Further research could focus on the sensory attributes and consumer acceptance of these blend oils to ensure market success, noting that sesame and sunflower involve agreeable pronounced aromas.
