RESUMO

In addressing the challenges of food security and nutritional deficiencies, the study aimed to assess the nutritional and techno-functional attributes of an extruded breakfast cereal composed of yellow maize, sorghum, and date palm. The processing involved transforming yellow maize, sorghum, and date palm into flours, and various samples (MA, MB, MC, SA, SB, SC, and MSD) were blended in different proportions (90:0:10, 80:0:20, 70:0:30, 0:90:10, 0:80:20, 0:70:30, 45:45:10, respectively) to create a nutritionally balanced extruded cereal. Standard methods were employed for the analysis to evaluate techno-functional properties (bulk density, water absorption capacity, oil absorption capacity, swelling power, and dispersability), mineral content (sodium, potassium, calcium, iron, and zinc), and color properties (brightness, redness, and yellowness) of the extruded breakfast cereal samples. Techno-functional property ranges were determined, such as bulk density (ranged from 0.39 g/cm³ to 0.50 g/cm³), water absorption capacity (ranged from 1.69 g/ml to 4.43 g/ml), oil absorption capacity (ranged from 1.56 g/ml to 2.14 g/ml), swelling power (ranged from 1.43 g/g to 4.27 g/g), and dispersability (ranged from 23.37% to 60.05%). Mineral content results included sodium (ranging from 10.88 mg/100g to 18.67 mg/100g), potassium (ranging from 253 mg/100g to 351.65 mg/100g), calcium (ranging from 321.50 mg/100g to 421.40 mg/100g), iron (ranging from 9.22 mg/100g to 15.2 mg/100g), and zinc (ranging from 4.11 mg/100g to 5.36 mg/100g). Colour determination exhibited brightness values ranging from 55.31 to 64.48, redness from 0.63 to 2.73, and yellowness from 10 to 17.37.The study demonstrated that extruded breakfast cereals combining yellow maize, sorghum, and date palm met acceptable quality standards in nutritional assessment. The use of date palm as a sugar substitute enhanced mineral bioaccessibility. Furthermore, the incorporation of date palm flour into maize and sorghum-based samples improved both techno-functional properties and mineral content, presenting a novel application for date palm fruits.

RESUMO

The effects of methanolic and chloroform extracts of the leaves of Alstonei boonei, a medicinal plant with anti-malarial, anti-inflammatory and analgesic properties, were assessed on liver mitochondrial membrane permeability transition (MMPT) pore were assessed in experimental animals in vitro and in vivo. The results obtained showed that calcium ions induced the opening of MMPT pore significantly (P< 0.05) in rat liver mitochondria, while spermine (0.1mM) inhibited calcium-induced opening of MMPT pore of these mitochondria thus, indicating that the mitochondria were intact, ab initio. The results further revealed the inhibitory effects of different concentrations of the various extracts of leaves of Alstonei boonei (200 microg/ml, 600 microg/ml, 1000 microg/ml, 1400 microg/ml) compared with spermine. Specifically, the data revealed that methanolic and chloroform extracts of leaves of Alstonei boonei reversed calcium-induced opening of MMPT pore in a concentration-dependent manner (26.5%, 27.4%, 56.4%, 69.3%) for methanolic extract of Alstonei boonei and (9.6%, 34.9%, 51.5% and 82.1%) for chloroform extract of Alstonei boonei, respectively. Although, the MMPT pore was not affected by low concentrations of the methanolic extract of Alstonei boonei (200 microg/ml and 600 microg/ml) in the absence of calcium, the extract at higher concentrations (1000 microg/ ml and 1400 microg/ml) induced the opening of the pore in a concentration-dependent manner. Mitochondria isolated from Wistar strain albino rats orally exposed to various doses of the methanolic extract of Alstonei boonei exhibited pore opening in the absence of calcium. In this respect, maximum (112%) induction of pore opening was obtained at 250mg/kg body weight, while minimum (31%) induction of pore opening was obtained at 200mg/kg body weight. Calcium further increased the extent of opening of the MMPT pore in animals previously exposed to methanolic extract of Alstonei boonei. These findings suggest that certain bioactive components of Alstonei boonei may be involved in inhibiting the opening of the MMPT pore in-vitro and in the induction of the opening of the pore at high doses of the extract with the eventual release of cytochrome C which is a prelude to the progression of programmed cell death.
