AI Article Synopsis
- Vitamin A deficiency (VAD) is a significant health issue in many developing countries, particularly affecting diets.
- Research on orange maize in Nigeria revealed that both the harvesting time and the presence of husk during roasting significantly impact carotenoid levels and sensory properties.
- The study found that β-carotene and provitamin A values increased with later harvesting times, with the highest concentrations occurring in specific hybrids when roasted with husks, suggesting methods to enhance nutritional value for consumers.
Article Abstract
Vitamin A deficiency (VAD) is a major public health problem in many developing countries. Orange maize is preferred as green maize and consumed roasted on the cob, especially in Nigeria. This research work was to evaluate the effects of harvest time and husk on the carotenoid contents and sensory properties of roasted orange maize hybrids. The results showed that husk (roasting forms) and harvesting time had significant effects (P ≤ 0.001) on the carotenoids and the sensory properties. There was general increase in β-carotene and provitamin A (PVA) values as the harvesting time increases. The β-carotene and PVA values for roasted orange maize hybrids with husk were higher than those for roasted without husk. Hybrid 5 had the highest β-carotene concentration and PVA value at 27 days after pollination (DAP) and 34DAP when unprocessed and roasted without husk. This information can help researchers in choosing proper roasting methods to increase the retention of high levels of β-carotene and PVA in orange maize that can be delivered to consumers through nutrition education.

Background: Orange maize genotypes are sources of provitamin A (PVA) carotenoids, which are precursors of vitamin A. PVA deficiency and drought constitute major challenges causing increasing food and nutritional insecurity in sub-Saharan Africa (SSA). Breeding of drought-tolerant provitamin A hybrid maize can mitigate these challenges.

- Malnutrition and food insecurity are significant issues in developing countries like Ethiopia, mainly due to economic challenges and limited access to diverse foods rich in protein and micronutrients.* -
- The research developed an instant porridge flour using extruded mixtures of maize, orange-fleshed sweet potato, sweet lupine, and moringa leaf powder in varying ratios to enhance nutritional value.* -
- Results showed that adding these ingredients significantly improved the nutritional profile of the porridge, increasing protein, vitamins, and minerals, while reducing carbohydrate content and moisture levels.*

Article Synopsis
- Child malnutrition is a significant issue in Sub-Saharan Africa, stemming from the low nutritional quality of locally available complementary foods.
- The study aimed to create nutritious, affordable canned porridges using African indigenous crops and ingredients, ensuring they meet dietary requirements for vitamins and energy.
- The resulting porridge, made with orange fleshed sweet potato and leguminous/cereal flours, provided essential nutrients and tasted better than traditional options, all while being cost-effective.

A low-fermentable oligo-, di-, monosaccharide and polyol (low-FODMAP) diet for patients with irritable bowel syndrome (IBS) should include an adequate fiber source. Our aim was to formulate orange cookies using maize flour and type-4 resistant starch (RS4) from maize and to evaluate their properties and sensorial attributes by IBS patients. We prepared two formulations: 37.

The main phenolic derivatives and antioxidant capacity of ninety-three yellow maize varieties were investigated, together with their color parameters. Sixteen phenolics were identified in the free extract by UPLC-ESI-MS/MS, N', N″-diferuloyl putrescine and N', N″-dicoumaryl spermidine were the major phenolic derivatives. Fourteen phenolic compounds were found in the bound extract, with trans-p-coumaric acid, trans- and cis-ferulic acid being the predominant phenolic acids.
