The aim of this study was to develop a nutrient-enhanced millet-based composite flour incorporating skimmed milk powder and vegetables for children aged 6-59 months. Two processing methods were tested optimize nutrient content quality flour, namely germination 0, 24 48 hr roasting at 80, 100, 140°C. amount ingredients in the formulation determined using Nutri-survey software. Germinating millet grains room temperature significantly (p < 0.05) increased protein (9.3%-10.6%), digestibility...

Vitamin A deficiency (VAD) is the world's commonest cause of childhood blindness. More than half these cases occur in developing countries. Animal sourced foods though good sources vitamin are too expensive for poor rural people. Crops biofortified with provitamin offer a convenient and accessible source A. The other micro-nutrient programs fortification supplementation require more inputs. Biofortification have developed crops that rich These include: maize, golden rice, cassava orange...

Abstract Background To determine the dietary patterns, anthropometric status, prevalence and risk factors for anaemia among school children aged 5–11 years in a peri‐urban area of Central Uganda. Methods A cross‐sectional study involving both qualitative quantitative methods was used. Anthropometric data were taken using standardised equipment, whereas haemoglobin assessed meter. Food intake food frequency questionnaire. One hundred twenty‐two primary children, years, their carers recruited...

Vitamin A deficiency (VAD) and under nutrition are major public health concerns in developing countries. Diets with high vitamin animal protein can help reduce the problem of VAD respectively. In this study, composite flours were developed from orange fleshed sweet potato (OFSP), amaranth leaves skimmed milk powders; 78:2:20, 72.5:2.5:25, 65:5:30 55:10:35. The physico-chemical characteristics determined using standard methods while sensory acceptability porridges was rated on a nine-point...

Culture is a strong determinant of food security through its influence on what society considers acceptable for consumption. Karamoja sub-region one the most ethnically diverse parts eastern Africa, and associated with highest levels insecurity in Uganda. However, there general lack understanding extent to which ethnicity contributing factor insecurity. We examined relationship between relation commonly practiced cultural norms among Jie, Karamojong Tepeth ethnic groups Karamoja. Data from...

Abstract Uganda has one of the youngest populations in world with about 78% its population below 30 years age, most which are adolescents. The boarding school diet fed to adolescents is rich carbohydrates and proteins but lacks adequate amounts micronutrients meet adolescent RDA requirements. This study aimed at contributing improvement nutritional status by developing an acceptable convenient instant vegetable soup protein (12.30 ± 0.25–13.26 0.25%), total carotenoids (154.19 12.62–292.68...

Children in resource poor settings are at a high risk of inadequate iron and vitamin A intake when diets lack diversity dominated by staple foods. Yet comparative information on diet quality among school children is scarce. The objective the study was to assess potential simple food group serve as proxy indicator status rural Uganda. cross sectional correlation model associations between Food Group Diversity (FGD) used. We analyzed 8 schools Kumi District, Uganda, randomly selected from 34...

The study was carried out to determine the effect of salt on sensory, nutritive and keeping quality OFSP crisps. Crisps were made by deep frying slices approximately 3.5 mm thickness treated with, 2% 4% table salt. A control with no treatment prepared alongside ones. Two varieties OFSP; Ejumula Kakamega used in study. After frying, crisps cooled room temperature, packed paper-lined high density polythene pouches stored a dark cupboard at temperature for three months. During storage period,...

Sweetpotato storage roots, peeled and unpeeled, of varying flesh colours (white, cream, yellow, pale orange, deep purple) were spectrophotometrically evaluated for their bioactive compounds antioxidant activities. Roots boiled, steamed, baked, fried, or microwaved. The unpeeled roots had relatively higher (p < 0.001) activities than the ones. All cooking methods increased phenolic compounds, flavonoids, tannins in all genotypes. Significant losses total carotenoids occurred with (ranging...

Millet porridge is a major complementary food used in Uganda but it limited protein and micronutrients such as zinc beta-carotene. Addition of milk vegetable powders are known to greatly improve the nutrient content millet flour. However, there was information on shelf stability resultant composite This study aimed at assessing effect millet-based flour.There general increase moisture content, peroxide value (PV), free fatty acids (FFA), thiobaturic acid (TBA) total plate count (TPC) both...

Orange-fleshed sweet potatoes {OFSP} (Ipomoea batatas (L.) Lam) contain high levels of beta carotene, an important provitamin A carotenoid. Stored potato roots undergo many physiological changes that affect their carotene content and bioaccessibility as well the tissue microstructure. This study investigated in microstructure, vitro stored OFSP roots. Roots two varieties OFSP, Ejumula SPK004/6/6 were each under following conditions: a pit (17-21 oC, RH 90-100%), saw dust (19-23oC, 86- 100%),...
