“…In Algeria, phoeniciculture is of great socio-economic and environmental importance because it is considered the linchpin on which life in the Saharan regions revolves. With over 18 million palm trees and more than 1,000 cultivars, Algeria occupies an important place among the world's date-producing and exporting countries (Benamara et al, 2017). This rise in consumption and production is directly proportional to the quantity of fruit waste generated.…”

Date fruit is a highly important crop cultivated in arid and semi-arid regions, known for its nutritional value and health benefits. Dates' benefits extend beyond their edible portion and include seeds, which are a by-product of different industries, often considered waste, and have untapped potential. This work aimed to optimize the extraction conditions of antioxidant compounds from date seeds and assess their ability to inhibit disease-related enzymes. The optimization was carried out by examining the main parameters, including solvent type (acetone, ethanol, methanol, and water), solvent concentration (25–100%), sample-to-solvent ratio (10–60/20 mg/ml), and extraction time (15–90 min). Phenolic content (PC) was determined using the Folin-Ciocalteu method, while antioxidant activity was evaluated by ABTS and DPPH scavenging assays, as well as ferric reducing power (FRP). Based on the statistical analysis, 75% acetone, 10 mg/20 ml, and 45 min were found to be the best extraction conditions, manifesting a PC of 128.65 mg GAE/g dw, antiradical powers of 244.91 mg TE/g dw (ABTS) and 64.27 mg GAE/g dw (DPPH), and a FRP of 64.27 mg GAE/g dw. Moreover, the extract of date seed demonstrated a promising inhibitory property against some key enzymes such as tyrosinase, acetylcholinesterase, and α-glucosidase, which may be considered a good candidate for managing diabetes, Alzheimer's disease, and neurodegenerative disorders.

“…To cope with the losses associated with excessive fruit ripening, studies have proposed the powder processing technologies on ripe fruits such as mangoes [10] and dates [11,12]. Others have produced enriched date powders by incorporating plants with interesting antioxidant activity, such as spirulina [13] and olive leaves [12]. Thus, such technology could be applied for the valorization of overripe plantain pulp, using tropical antioxidant-containing plants.…”

Enhancing the quality of overripe plantain powder by adding superfine fractions of Adansonia digitata L. pulp and Hibiscus sabdariffa L. calyces: characterization and antioxidant activity assessment

et al. 2020

In this study, the overripe plantain has been used to produce high-antioxidant powders, using Adansonia digitata L. pulp and Hibiscus sabdariffa L. calyces as antioxidant supplements. The constrained mixture design (ranged between 0.9-1.0 for plantain and 0-0.1 for supplements) was used to generate ten powder formulations. The obtained powders were evaluated for physicochemical properties and antioxidant activities. Generally, significant differences (p < 0.05) were found between moisture, proteins, ash, fibers, carbohydrates and fat contents of different raw material powders. The increase in the proportions of A. digitata L. and H. sabdariffa L. significantly increased (p < 0.05) the levels of polyphenols (40.19-583.46 mg GAE/100 g DM), flavonoids (18.27-103.46 mg RE/100 g DM), condensed tannins (28.73-276.47 mg CE/100 g DM), carotenoids (8.41-9.48 mg/100 g DM) and vitamin C (31.55-77.30 mg/100 g DM) in the formulated powders. The antioxidant properties of the powder formulations revealed higher radical-scavenging activities DPPH (IC 50 of 0.80 mg/mL) and ABTS (IC 50 of 1.51 mg/mL) for M10 formulation consists of 91.67% overripe plantain, 1.67% A. digitata L. and 6.66% Hibiscus sabdariffa L. The best reducing powers were found in M5, M6 and M10 formulations which improved by more than 2 to 3 times the value of M1 (2.66 mg AAE/g DM) not containing antioxidant supplements. M10 was the powder formulation that exhibited the best antioxidant activities despite its low hydration capacity. A. digitata L. pulp and H. sabdariffa L. calyces revealed the potential for an efficient improve of antioxidant activity of overripe plantain powder. High-antioxidant powders from the mixtures showed promise in helping to combat oxidative stress in Africa and other countries where chronic diseases pose a threat.
