Background/Aims: Traditional edible plants are good sources of minerals, fibers, proteins and others useful phytochemicals for human nutrition and health. Mondia whitei and Pyrenacantha klaineana leaves are underutilized, wild edible plants considered as food and spice in habitants in some part of Northern Angola. The aim of this study was to investigate the nutritional value and mineral contents of M. whitei and P. klaineana leaves. Materials and Methods: The leaves were harvested from a forest. The samples were analyzed for proximate and mineral contents using the standard methods. The results were analyzed statistically using mean and standard deviation. Results: The proximate composition of M. whitei raw and cooked leaves showed that the samples had ranged of ash, 9.53 - 12.93%, fiber 13.16 - 15.11%, protein 16.48 - 19.24%, fat 2.95 - 4.94%, carbohydrates 51.59 - 54.48% and energy (kcal) 310.39 - 326.10 in 100 g respectively. The proximate composition of P. klaineana raw and cooked leaves showed that the samples had range of ash, 4.13 - 6.74%, fiber 40.45 - 43.56%, protein 14.93 - 18.80%, fat 1.13 - 3.78%, carbohydrates 29.74 - 36.58% and energy (kcal) 217.77 - 227.88 in 100 g respectively. The mineral contents of the P. klaineana raw leaves, K 2459.20 mg, Ca 2126.33 mg, P 239.90 mg, Se 77.86 mg are richer than M. whitei raw leaves, K 1149.83 mg, Ca 844.87 mg, P 175.89 mg, etc. Conversely, the leaves of M. whitei are richer in Se 87.80 mg and Cu 3.14 mg/ 100 g than the P. klaineana (Se 77.86 and Cu 2.84 mg/100 g). Conclusion: The wild edible leaves are rich in nutritional value and mineral composition such as fiber, protein, Ca, Fe, K, Mn, Mg, P, Se etc. The consumption of M. whitei and P. klaineana leaves should be vulgarized to nutrition, diversity diet and food security.

The nutritional and anti-nutritive composition of Karaya gum tree (Sterculia setigera) seed collected from Federal College of Wildlife Management estate, New Bussa, Nigeria was evaluated from October to December, 2013 with the aim of providing data that will guide the effective utilization and inclusion of this under exploited tropical plant seed in fish feed formulation. The seeds were washed, dried, grounded and analyzed for the proximate composition, vitamin and mineral contents as well as the anti-nutritive factors using standard procedures. The result showed that the mean values for the proximate composition were: moisture 5.20%, ash 3.95%, fat 26.03%, fiber 6.15%, protein 13.39% and carbohydrate 45.27%. The plant also contained vitamins and relatively adequate essential mineral elements of nutritional importance of macro elements such as calcium, potassium, sodium, magnesium and micro elements of iron, manganese, zinc and copper. Some anti-nutritional factor such as; alkaloids, phytate, cardiac glycosides, flavonoids, steroids and trace of oxalate were also found in the plant, but their composition will pose no serious  nutritional problem if well processed before its inclusion in fish diet and could therefore be a cheap source of raw materials for the fortification applications in various fish feed formulations.

The biochemical composition of three cultured cichlids (Tilapia zilli, Tilapia guineensis and Orechromis aureus) were evaluated and compared.  The proximate composition of the cichlids was determined using official methods of analysis, mineral composition was determined using Atomic Absorption Spectrophotometer and the amino acid composition was analyzed using Amino Acid Analyzer. The proximate composition of the three cultured species of tilapia fish (T. zilli, T. guineensis and O. aureus) indicated that moisture content, crude fat, crude fiber and ash content showed significant difference (p<0.05) among the three species while crude protein and carbohydrate content showed no significant difference (p<0.05) among the three species. The mineral contents such as zinc, magnesium and manganese showed significant difference (p<0.05) among the three species of tilapia (T. zilli, T. guineensis and O. aureus) while sodium, potassium, calcium, iron, phosphorus and copper contents showed no significant difference (p<0.05) among the three species. The amino acid composition showed lysine as the most abundant amino acids present in all the cultured cichlids studied. This shows that these cultured cichlids are highly nutritious and would be of great value to consumers.

The present study aimed to produce and evaluate the physicochemical composition of an improved and enriched roasted corn flour with soybean (5%) and groundnut (5%) flours comparatively to its traditional preparation for homemade complementary foods. Samples of (corn, soybean and groundnut) were dried and milled to produce two types of roasted corn flour: the roasted corn flour with soy and peanut and the traditional roasted corn flour with corn only. Laboratory analyses of chemical proximate like nutrients, minerals and anti-nutrients properties were determined according to standard procedures. Data generated were subjected to one way analysis of variance using using SPSS 11.0 software. The results showed that there were significant differences (P<0.05) among the samples. Regarding proximate composition, the composite roasted corn flour is distinguished by higher crude fat (5.83%), protein (19.66%), carbohydrate (62.31%), fiber (3.67%), ash (1.85%) and calorific (442.99 Kcal/100 g) value. Likewise, mineral contents increased significantly (p<0.05) in the composite roasted corn flour with high value in all the studied minerals including potassium (779.11 mg/100 g), phosphorus (242.83 mg/100 g), calcium (132.45 mg/100 g), zinc (2.67 mg/100 g) and iron (1.44 mg/100 g). The studied of anti-nutrients, showed that composite roasted corn flour also exhibit lower value in oxalate (8.03 mg/100 g) and phytic acid (3.48 mg/100 g). It could be concluded that the composite roasted corn flour appears to be suitable for homemade complementary foods to cover infant and young children needs.

Fish with higher nutrient qualities can be used to solve malnutrition problems in Africa. So the aim of this study was to evaluate the effect of local smoking on proximate composition and lipid oxidation of Chrysichthys nigrodigitatus collected in Cameroon. The proximate composition was assessed using standard methods while lipid quality assessment was based on the determination of biochemical indexes. A change on fatty acid composition was evaluated by gas chromatography while minerals composition was evaluated by spectrophotometer. On nutritional point of view, raw fish have high protein, lipid and ash contents (51.87, 37.48 and 8.55 g/100 g dry weight respectively). Unsaturated fatty acid may be up to 57% of the total fatty acids. Raw C. nigrodigitatus contain reasonable amount of minerals. Smoking process increased ash and lipid content while proteins and moisture contents are reduced in these fish. The iodine value of C. nigrodigitatus was reduced while acid, peroxide and TOTOX values increased during smoking. The marked decrease of polyunsaturated fatty acids was noted during processing. Mineral contents were affected by smoking process. Calcium, magnesium, potassium, sodium, manganese and iron contents increased significantly. In conclusion, hot smoking enhances nutrients content of C. nigrodigitatus while significant reduction in lipid quality was recorded.Keywords: Chrysichthys nigrodigitatus, smoking process, nutritional value, lipid oxidation, mineral contents. Frence Title; Effet du fumage traditionnel sur la composition chimique, l’état d’oxydation des lipides, la composition en acide gras et la teneur en minéraux de Chrysichthys nigrodigitatus du Lac Maga au Cameroun Le Poisson est l’une des sources d’éléments nutritifs de qualité pouvant contribuer à prévenir la malnutrition en Afrique. Ce travail s’est donné pour objectif d’évaluer l’effet du fumage traditionnel sur la composition chimique et l’état d’oxydation des lipides de Chrysichthys nigrodigitatus provenant du Lac Maga au Cameroun. Les méthodes standards ont été utilisées pour la détermination de la composition chimique, la mesure de l’état d’oxydation des lipides par des indices chimiques, la composition en acides gras par chromatographie en phase gazeuse et les minéraux par spectrophotométrie. Du point de vue nutritionnel, ce poisson frais contient respectivement 51,87 ; 37,48 and 8,55 g/100 g de matière sèches de protéines, lipides et cendres. Il contient également 57% d’acides gras insaturés et une quantité raisonnable de minéraux. Le traitement de fumage provoque une augmentation de la teneur en cendres et en lipides. Par contre la teneur en eau et en protéines diminuent. L’indice d’iode baisse tandis que les indices d’acide, de peroxyde et de TBARs augmentent. Une diminution du taux d’acides gras polyinsaturés est observée. Les minéraux sont également affectés au cours du fumage. Le traitement de fumage améliore la teneur en nutriments de C. nigrodigitatus, par contre réduit la qualité lipidique de celui-ci. Mots clés : Chrysichthys nigrodigitatus, fumage, valeur nutritionnelle, oxydation des lipides, teneur en minéraux.
