Abstract:

An investigation into anti¬-nutrient compositionof mumu, a traditional dish in Benue State, Nigeria, was carried out. Formulation of blends was based on different levels of roasted pearl millet flour (RPMF), boiled Irish potato flour (BIPF), and roasted sesame seed flour (RSSF). The three ingredients were combined in the following ratios: RPMF 100 (control), 70:20:10, 65:25:10 and 65:20:15 of RPMF: BIPF: RSSF, respectively. Mineral bioavailability was evaluated by [Oxalate]/[Ca], [Phytate]/[Ca], [Phytate]/[Fe] and [Phytate]/[Zn] molar ratios of the different blends of mumu were investigated, t

Abstract:

Red Vine Fruits (RVFs), a wild edible fruits, are sought as an alternative food source to prevent hunger and malnutrition. This study aimed to investigate the impact of the non-nutritive compounds on the bioaccessibility of critical minerals in pre-treated RVFs using standard analytical methods. The result of mineral composition of RVFs showed that magnesium had the highest (940.33 ± 0.01), followed by potassium (389 ± 0.01), calcium (215.80 ± 0.01), and copper (2.53 ± 0.01) as the least content in mg/100 g. The non-nutritive compounds found (mg/100 g) were phytates

Abstract:

African yam bean has immense food and nutrition potential and is resilient to adverse environmental conditions. Despite its potential, the crop is underutilized, which could be attributed to seed hardness (requiring about 6–24 hours of cooking time); and the abundance of antinutrient factors (tannin, phytate, and oxalate). This study evaluated the physical (seed hardness, cooking time) and chemical compositions (crude protein, tannin, phytate, and oxalate) of 93 AYB accessions grown in Ethiopia. The seed hardness of each accession was determined by the compression force and compression time us

Abstract:

Phytate has been classified as an anti-nutrient, but there are no adverse effects from the consumption of a balanced diet with 1 to 2 g of daily phytate (inositol-hexaphosphate, InsP6) as a calcium magnesium salt, the form naturally present in grains. Furthermore, recent research has shown that phytate consumption may prevent pathological calcifications, such as kidney stones and cardiovascular calcifications. However, many endogenous and exogenous enzymes can hydrolyze phytate to lower inositol phosphates (InsPs) that also have biological activity. We performed a controlled hydrolysis of phyt

Abstract:

African eggplants are highly valued constituents of the Nigerian food. However, their nutritional potentials have not been fully tapped due to inadequate information on their nutritional and anti-nutritional qualities. This present study investigated the proximate, minerals, anti-nutrient contents as well as the estimation of mineral ratios and Mineral Safety Index of four selected edible solanum species namely, Solanum anguivi, S. gilo, S. menalogena and S. aethiopicum. The proximate contents (%) ranged from 4.19-5.46 (moisture content), 1.71-2.49 (crude fat), 4.57-5.45 (crude ash), 3.76-4.93

Abstract:

In rhizospheric soil, arsenic can be activated by both biological and abiotic reactions with plant exudates or phosphates, but little is known about the relative contributions of these two pathways. The effects of microorganisms, low-molecular-weight organic acid salts (LMWOASs), and phosphates on the migration of As in unrestored and nano zero-valent iron (nZVI)-restored soil were studied in batch experiments. The results show that As released by microbial action accounted for 17.73%, 7.04%, 92.40%, 92.55%, and 96.68% of the total As released in unrestored soil with citrate, phytate, malate,

Abstract:

Cereals remain the major components of traditional complementary foods but possess antinutritional factors in addition to nutrients. High antinutrient content have been linked to poor quality complementary foods and high level of undernutrition among children less than two years. Hence, this study examined the effect of fermentation, germination and combined germination-fermentation processing methods on the nutrient and antinutrient contents of Quality Protein Maize (QPM). Maize seeds were fermented and germinated for 72 hours. A batch of the germinated seeds was further fermented for 24 and
