ABSTRACT
Malnutrition and micronutrient deficiencies during infancy and early childhood are major problems facing developing countries, particularly Cameroon. This study aimed to formulate highly nutritious infant foods from locally available and affordable raw materials: orange-fleshed sweet potato (Ipomoea batatas L.), beans (Phaseolus vulgaris L.), and peanuts (Arachis hypogaea L.) grown in Cameroon. The formulated diets were analysed for their proximate (protein, fat, ash, fibre, carbohydrates), mineral (iron, zinc, calcium, magnesium, phosphorus), and antinutritional contents using standard methods. They were compared with the FAO/WHO standards. A total of two formulations were produced, with compositional proportions calculated based on recommended daily allowances (RDAs) for young children. The formulated ingredient varied 57-58% sweet potato, 23-25% beans, and 18-19% peanut. The linear programming method combined the samples into different formulations to meet FAO/WHO/UNICEF requirements. The results showed that the nutritional composition of the flour on a dry weight basis was as follows: crude protein: 12.66-13.66g/100g, lipid: 8.95-9.13g/100g, carbohydrates: 61.58-63.71g/100g, fibre: 5.58-6.22g/100g, ash: 3.82-4.64g/100g, energy: 381.53-387.65 Kcal, iron 9.45-10.46mg/100g, zinc 3.00-4.24mg/100g. The proximate contents of the formulated flours meet the FAO/WHO standards, except the energy content. The results of the study showed that the formulated diets contain very low antinutritional factors (phytate: 0.12 mg/100g and trypsin inhibitory content 0.30 to 0.35mg/100g). Based on the results, the complementary food formulated from sweet potato, beans, and peanut flour is a good source of protein, iron, and zinc and would contribute to the daily requirements of infants and young children.

ABSTRACT
The present study investigated the storage stability of sponge cakes at room temperature with the aim of evaluating the influence of different flour combinations on the colour, taste, aroma, aftertaste, and overall quality of sponge cakes. Additionally, this study examined the shelf life of cakes stored under ambient conditions. A trained panel conducted a descriptive sensory analysis of genoise sponge cake samples made with different flours using a linear scale to assess their shape, colour, aroma, taste (sweetness), and aftertaste. The mean scores for cake colour showed that all samples had the characteristic colouring of genoise sponge cake. The aroma ratings were pleasant for all samples, and sweetness was moderate. The aftertaste was pleasant for two of the samples (W12 and S12), while the third sample (P12) had a slightly distinct aftertaste. The addition of potato and soybean flours positively affected acceptability, but the control sample (W12) scored the highest overall acceptability, indicating a strong preference for all samples. After three days, the cakes remained visually appealing but deteriorated by day six, and the S12 sample became excessively oily, whereas the W12 and P12 samples developed significant mould. These findings suggest that sponge cakes should not be stored for more than three days at 28-30°C.

ABSTRACT
Background: Overweight and obesity are conditions related to Type 2 Diabetes Mellitus (T2DM). T2DM cases have increased in line with the overall increase in the incidence of overweight and obesity. Aim of the Study: To investigate the role of local nutrition in the onset and diffusion of T2DM in the Republic of Congo. Methods: Clinical and nutritional information have been recorded for 40 male Congolese subjects. In the non-diabetic group, a Diabetes risk score was submitted to assess the risk of developing T2DM within 10 years; the Knowledge-Attitude-Practice (KAP) questionnaire was submitted to the T2DM diagnosed group. Results: results show a high level of daily calories intake, not justified by physical activity level. The role of nutrition in the treatment of T2DM is not recognized and the pathology remains not well known despite the data confirming its spread among the population. The analysis of clinical data shows a high prevalence of overweight/obesity and hypertension among those at risk of developing T2DM and those diagnosed with T2DM. Conclusion: The goal of this study aimed to implement future projects and strategies to induce local health care staff to focus more attention on changing food style and to increase nutritional re-education therapy in both diabetics and people at risk.

ABSTRACT
Honey bee brood (lava and pupa stages of honey bee) and pearl millet are two food items that are locally available in Kenya, culturally accepted and often consumed in many parts of the world including Arid and Semi-Arid Lands (ASALS). However, there is limited documented literature on characteristics of pearl millet and honey bee brood. Such information is important to inform production, processing, and value addition. This systematic literature review aims to determine the nutritional composition, use, acceptability, strengths and threats, as well as effects (on weight, height or biochemical composition in children) of pearl millet and honey bee brood. A total of seventy relevant articles published in 1980 to 2023 searched on Cochrane Library, PubMed, and Google Scholar were included in the study. Pearl millet was presented to have high calorie, and balanced micronutrients. On the other hand, honey bee brood was described as rich in protein, fats, vitamins, and minerals. Combining the two in conventional diet would provide adequate nutrients for humans when utilized as food. Due to presence of high contents of balanced amino acids, especially leucine, histidine and the high caloric nature of pearl millet and bee brood, the two can be promoted for malnutrition prevention and resolution in the arid and semi-arid lands where they are produced.

ABSTRACT
A feeding trial was conducted to determine the effects of black pepper, tumeric, corriander and their blend as supplementary phytoadditives in dosage 1 kg per ton of feed on the growth performance and meat sensory assessment of broiler chickens. A total of three hundred (300) day-old broiler chicks were used for the study. At the starter phase, the chicks were weighed at day old and randomly assigned to five dietary treatments in a completely randomized design (CRD). Feed and water was provided ad libitum during the trial period. The birds were weighed at the beginning of the trial and weekly thereafter. Weight gain, feed intake, left over feeds were measured and recorded, feed conversion ratio and feed cost per kilogramme weight gain were calculated and mortality rate recorded as they occurred. Medication and vaccine administration was carried out as required. Performance parameters calculated include feed intake, weight gain, feed to gain ratio, feed cost per kilogram gain and mortality. For the finisher phase, one hundred and five four weeks old chicks were allotted to five dietary treatments in a completely randomized design (CRD). The treatments were replicated three times with fifteen chicks per replicate. Performance parameters measured were the same as for the starter phase. The experimental study lasted seven weeks. Data obtained were subjected to analysis of variance using SAS (2008), while the significant differences between treatment means were separated by Duncan Multiple Range Test at a 5% level of significance. There were significant (p<0.05) differences in final weight, weight gain, feed consumption, feed conversion ratio, feed cost per gain and mortality. Birds fed corriander supplemented diet (T4) had significantly (p<0.05) higher final weight, weight gain and least cost of production which were at par with birds fed black pepper supplemented diet (T2). The least performance was observed for birds fed black pepper, tumeric and corriander ..........

ABSTRACT
The increasing human exposure to dichlorvos (DDVP) and its toxicity is a growing public health concern. This work was aimed at studying the therapeutic effect of Vernonia amygdalina, Ocimum gratissimum, Talinum triangulare extracts against DDVP induced hepatotoxicity in rats. Total of 50 male adult rats of average weight 272g were placed in ten groups (n=5) and orally administered normal saline (normal control), 8.0mg/kg body weight DDVP (positive control), 8.0mg/kg body weight DDVP + 200mg/kg and 400mg/kg body weight of the plant extracts and 20 mg/kg body weight and 40 mg/kg bodyweight of vitamin C for 28 days. DDVP significantly (P<0.05) increased Alanine aminotransferase (ALT), Aspartate aminotransferase (AST), Alkaline phosphatase (ALP) and Gamma glutamyl transferase (GGT) when compared with normal control. Treatment with aqueous leaf extracts of Vernonia amygdalina, Ocimum gratissimum, Talinum triangulare significantly reversed the distortions in the values of biochemical parameters when compared with positive control. Photomicrographs obtained from histological examination of liver tissues corroborate these findings. Aqueous leaf extracts of Vernonia amygdalina, Ocimum gratissimum, Talinum triangulare may have therapeutic potentials to DDVP induced hepatotoxicity in rats.
