Maize, soybean and peanut were blended in a ratio of 60:30:10 to produce a complementary food, which was then fortified. While the unfortified food product (sample A) served as control, the other three formulations were fortified with 5%, 10% and 15% Moringa leaf powder to give three samples (B, C and D respectively) of fortified food. Nutritional composition determination and feeding trials were then carried out, using two weeks old male albino rats to determine the performance of the food formulations. While the crude protein, crude fibre, and ash contents of the diets increased significantly (p with fortification, with values ranging from 16.04% to 17.59%, 2.25% to 4.42% and 1.40% to 2.50% respectively, crude fat and carbohydrate decreased significantly (p < 0.05), with concomitant decrease in energy, with values ranging from 23.48% to 20.80%, 49.32% to 47.63% and 472.76% to 448.08 kcal/100g respectively in samples A to D. PER values significantly (p < 0.05) improved up to 10% substitution, from 1.77 in unfortified (sample A) to 1.90 in 10% fortified (sample C), but declined at 15% substitution (sample D) to 1.69. Similarly, NPR values increased from 0.71 to 0.76 and 0.68. However, all the PER values including that of Nestle Cerelac (2.04) were lower than, though within the same range, with the value of 2.10 recommended by the Protein Advisory Group (PAG) for complementary foods. Sample C (10% Moringa flour blend) gave the best performance after rat feeding trials.展开更多

Methods: Amlodipine besilate (AMPB) powder was used as a model drug. Starch- and xanthan gum-based food thickeners were examined, with swallowing-aid jelly as a reference. The line-spread test (LST), texture prolife analysis (TPA) were done firstly. In related to AMPB powder mixed with food thickeners solution, a conventional dissolution test simulating the oral cavity was performed, the amlodipine (AMP) concentration and taste sensor output for dissolved medium versus time profiles were developed. The dissolution test at pH 1.2 and 4.5, representing typical gastric conditions for younger or elderly people, was performed in two kinds of thickener solution and swallowing-aid jelly those were mixed with AMPB powder. Results: LST demonstrated that xanthan gum-based food thickeners fulfilled the requirements for patients with dysphagia but that starch-based food thickeners did not. In TPA, hardness and adhesiveness decreased proportionally as the concentration increased for both kinds of food thickener. Conventional dissolution test simulating oral cavity demonstrated the following bitterness ranking: xanthan gum-based food thickener Conclusion: Although xanthan gum-based food thickeners were successful in masking the bitterness of AMP, they may reduce its bioavailability in humans. The 7.1 and 4.7 (w/v) % starch-based thickener show bitterness inhibition under simulated oral cavity conditions and complete dissolution of AMP under simulated gastric conditions.展开更多

Both iron deficiency and iron excess during the fetal and neonatal period bode poorly for developing organ systems. Voltammetry is analytical method based on current potential measurements in electrochemical cells. In this study the concentration of iron in four brands of powder milk and baby food (based on rice and based on wheat) was analyzed with DPASV and voltammeter device. Total Means ± SE of Iron in baby foods and powder milk (n = 40) were 8.55 ± 1.18 mg/100g, 5.21 ± 0.66 respectively. Iron level in baby food type I and II was lower than labeled value (p p < 0.05).展开更多

Each study was further divided into three groups to ensure the provision of selected diets, i.e.,control, functional and nutraceutical diets. Each study was further divided into three groups to ensure the provision of selected diets, i.e., control, functional and nutraceutical diets.Results: Declining trend for total cholesterol was observed in all studies with maximum reduction(8.55%) in rat group fed on nutraceutical diet in study Ⅲ. Likewise, levels of low density lipoproteins and triglycerides reduced 11.39% and 7.89% respectively in hypercholesterolemic rats. Moreover, nutraceutical diet alleviated the sera glucose level by 8.96% in study Ⅱ.Conclusions: Conclusively, inclusion of citrus peel bioflavonoids in dietary therapies is a promising strategy to modulate lipidemic and glycemic attributes without imparting any deleterious effect on hematological parameters.展开更多
