Abstract The objective of this study was to determine the proximate and microbiological compositions of some food samples obtained at three different locations within Ibadan Metropolis, Nigeria from different local food vendors. The highest mean carbohydrate, crude protein, fat, moisture, total ash and crude fibre are 88.10 ±0.79% (Roasted Yam), 17.76 ±2.29% (Roasted Fish), 20.54 ±4.0% (Suya Meat), 20.27 ±11.43% (Roasted Plantain), 4.57 ±0.10% (as in Suya Meat) and 5.07 ±0.69 (Roasted Plantain) respectively while the lowest mean carbohydrate, crude protein, fat, moisture, total ash and crude fibre are 49.14 ±1.37% (as in Fried Bean Cake), 0.08 ±0.01% (Roasted Yam), 0.47 ±0.05% (Roasted Yam), 1.81 ±0.33 (Roasted Fish), 1.37 ±0.12 (Doughnut) and 0.16 ±0.06% (Fried Bean Cake) for all the samples estimated. The highest mean heterotropic bacteria and fungi counts are 6.19× 103 cfu/ml (Roasted Yam) and 3.30× 103 cfu/ml (Fried Bean Cake) respectively while the lowest mean heterotropic bacteria and fungi counts are 1.64× 103 cfu/ml (Doughnut) and 1.08× 103 cfu/ml (Roasted Plantain) respectively. These food samples were shown to contain certain level of proximate parameters but these are not sufficient for nutritional requirements in human diet. Increasing the shelf-life of foods is one of the major purposes in food processing. Processes which precede food processing causes loss of essential vitamins and minerals. Also, roasted foods sold along Nigerian road-sides are exposed to dust accumulation and wastes from automobile exhaust.

This study was conducted to evaluate the effect of oven drying on the proximate composition and rehydration characteristics of shellfish. Shellfish studied included rough and smooth periwinkle, oyster and whelk. Proximate composition of the fresh samples were determined. Then dried in the oven to a moisture content of 10% and further rehydrated with distill water in sample water ratio of 1:40 and allowed to equilibrate. Proximate composition of the fresh shellfish showed that moisture content ranged from 82.38 to 69.24% with fresh smooth periwinkle having the highest moisture value while whelk had the lowest. The results also showed that whelk had the highest values for ash (2.92%), crude protein (18.83%) and crude fibre (3.71%) when compared to other samples. On rehydration, a moisture loss of 11.75%, 13.28%, 19.24% and 22.04% were observed for rough periwinkle, smooth periwinkle, oyster and whelk, respectively. The results for rehydration indices revealed that dehydration ratio was significantly (p<0.05) high for whelk (1.44), followed by oyster (1.29), rough periwinkle (1.23) and lastly, smooth periwinkle 1.20. Rehydration ratio of whelk (1.47) was equally significantly higher, followed by oyster (1.33) and the least were rough and smooth periwinkle (1.17). For coefficient of reconstitution, oyster recorded the highest value of 1.03, followed by whelk 1.02, rough periwinkle 0.95 and smooth periwinkle 0.98. Rate of water imbibition revealed a sharp increase in the water content of smooth periwinkle up to 240 min and thereafter, it slowed down until equilibrium was reached. In terms of rough periwinkle, oyster and whelk; water imbibition took place with rehydration time up to 300 min, 210 min and 270 min, respectively, thereafter they slowed down. The results have demonstrated that the rate in which oven drying affect the physical and nutritional qualities of shellfish differs.

The levels of proximate composition, minerals, antinutrients, fibre components and calculated parameters for mineral bioavailability were determined in the testa, dehulled and whole seeds of Bambara groundnut on dry weight basis. Proximate levels were (g/100 g): ash (2.46- 4.36); crude fat (2.47-6.99); crude protein (15.2-22.2); crude fibre (1.03-22.9) and carbohydrate (51.6-61.9). The non-starch polysaccharide (NSP) components were (%): ADF, 7.13-29.0 (or 16.1 %-65.5 %); NDF, 1.77-23.6 (or 6.28 %-83.7 %); ADL, 6.15-28.0 (or 14.9 %-67.8 %); cellulose, 1.36-23.3 (or 5.02 %-86.0 %) and hemicellulose, 0.84-26.5 (or 2.86 %-90.1 %). In minerals (mg/100 g): Mn, Co and Cu were not detected; Na, K, Ca, Mg, Fe and P were low in values whereas Zn was high at 11.2-40.2. These parameters were also good for human health: Na/K (0.47-0.51) and Ca/Mg (2.58-4.36). Antinutrient values showed that Phy was high (14.4-29.2 mg/g); oxalate was high (5.02- 8.59 mg/g) and unavailable phosphorus as Pp % of P (10.2-49.3 %). The mineral bioavailability showed Ca/Phy to be good at 0.20-0.89 and [Ca] [Phy]/[Zn] to be good at 0.09-0.23 thereby making Zn bioavailable in all the samples.

Sweet potato (Ipomoea batatas (L.) Lam) is one of the main crops worldwide. However, systematic properties characterization of this crop is still required, particularly on the Malaysian local sweet potatoes. Hence, this study aims to determine the proximate composition and the energy value of five common varieties of local sweet potato (Anggun 1, Anggun 2, Anggun 3, White, and VitAto) in Malaysia. For each variety, three different parts of the tuberous root which were the skin, the cortex, and the mixture of cambium and parenchyma were characterized. The findings indicated that VitAto exhibited the highest starch (16.95% – 17.17%) and crude protein (0.86% – 1.15%) contents in all parts as compared to other varieties, hence reflecting its potentials to be further processed for a mass starch production. Among all the parts, the skin contained the highest crude protein, crude fat, ash and crude fibre, which can be further utilized to produce by-products such as animal feed. The findings in this study serve as a baseline for the future starch and byproducts production from local sweet potatoes.

Infant formula is a synthetic version of mother’s milk and belongs to a class of food materials known as dairy substitutes. This study was designed to evaluate the proximate composition of some selected infant formula sold in Makurdi metropolis. Six (6) different brands of infant formula samples were purchased from the major markets, Wadata market and North bank market Makurdi Benue State, North Central Nigeria. The six different brands comprise of three (3) infant milk formulae and three (3) infant cereal formulae. Samples on some Selected Infant Formulae were analysed in the laboratory for proximate composition and the data were subjected to Analysis of Variance to rank the significant differences in means. There were significantly different (P<0.05) across the selected infant formulae sample for moisture, ash, crude protein, crude fate, crude fibre and carbohydrates. The result shows that FRISOGOLD significantly (P<0.05) has the highest moisture content (11.60%) with cowbell having the lowest (2.45%) while the ash content of cowbell was found to be the highest compared to other formulae. In conclusion, the commercial baby food samples (MYBOY, NAN and cowbell) have a low moisture content which suggests an asset as this prolongs the shelf life and also inhibits microbial activity on these products thereby preventing spoilage.

Aim: This study was conducted to evaluate the influence of fermented maize-meal infusion on feed quality, growth performance and immune status of African catfish, Clarias gariepinus fingerlings. Place and Duration of Study: Department of Biochemistry, Ibrahim Badamasi Babangida University, Lapai, Nigeria, between March 2017 and July 2017. Methodology: A total of 120 African catfish, Clarias gariepinus fingerlings (mean initial weight 7.43±0.24 grams) were randomly distributed into 2 groups of 3 replicates each. Each replicate contained 20 fish. Fermented feed (FF) produced using fermented maize-meal (ogi) infusion for 72 h was fed 5% body weight to a group of 60 fish (in 3 replicates) for 10 weeks, compared to fish fed control pellet containing similar ingredients but was non-fermented (NF). Proximate composition of feeds and whole fish, feed efficiency and growth performance, biochemical and antioxidant parameters in African catfish, Clarias gariepinus were evaluated. Results: The results of proximate composition of FF and NF diets were not significantly (P>0.05) different in crude protein, crude fibre, carbohydrate and moisture contents. However, fat (lipid) was significantly lower in FF diet, while the level of ash was significantly (P<0.05) higher in FF than in the NF control. Proximate composition of whole fish fed NF and FF diets are significantly similar for crude protein, crude fibre, fat and carbohydrate contents. However, ash and moisture contents were significantly higher in fish fed NF than FF. The results for feed efficiency and growth performance of African catfish fed experimental diets indicated similar feed acceptance and intake and consequently similar growth performance. The hematological indices; packed cell volume (PCV), white blood cell (WBC), red blood cell (RBC) and haemoglobin (Hb) were observed to be significantly higher in fish fed the FF diet. The activity of aspartate aminotransferase (AST) was significantly elevated in serum of fish administered the non-fermented diet while alanine aminotransferase (ALT) and alkaline phosphatase (ALP) indicated elevated activities in fish fed fermented diet. The chloride and potassium ions and cholesterol indicated significantly higher concentration in the serum of fish fed fermented diet. Conversely, the inorganic phosphate, calcium, total protein and triglycerides were significantly higher in the serum of fish fed the non-fermented diet. Contrastingly, the concentration of sodium ion and creatinine did not differ significantly between the fish fed the experimental diets. The activities of superoxide dismutase (SOD) and catalase (CAT) were significantly elevated in the serum of fish fed FF diet. Conclusion: Fermented diet with probiotics from maize-meal infusion improved biochemical and antioxidant parameters of Clarias gariepinus without impairing fish performance.

A study on the effect of organic manure on seedling growth and proximate composition of T. africana seedlings was conducted to influence the growth and improve the nutritive quality of the plant as an alternative source of feed for dry season feeding. Three months old seedlings of T. africana were transplanted on the field containing samples of organic manure (poultry and cow dung) mix with top soil in a ratio of one kilogram of soil to 25 g of manure and a control (without manure) in a Randomized Complete Block Design which was replicated thrice. The seedlings were assessed for plant height, number of foliage, collar diameter and number of branches. Samples of the seedlings foliage were collected across the treatments and analyzed for proximate composition after the eighth week of transplanting. Seedlings under cow dung application recorded a significantly (P>0.05) higher values for number o foliage per plant (21.82), plant height (66.58 cm), collar diameter (12.96 mm) and number of branches (4.20) at 8 weeks after planting (WAP), followed by seedlings to which poultry manure was applied and lastly by the control. Proximate composition showed that the dry matter (DM) content values of the samples were high which ranged from 894.60- 896.30 g/ kg DM (p<0.05). The crude protein (CP) content followed the same trend as the DM with its values ranging between 143.6 and 149.30 g/kg DM (p<0.05) and the ether extract (EE) values ranging between 22.20 and 23.50 g/kg DM (p<U.05) for the samples collected respectively. The ash content did not vary significantly between the different manure and the control. The Crude fibre was quite significantly (p<0.05) low in the samples ranging from 162.10 and 166.70 g/kg DM. This study showed that cow dung is the most suitable manure for T. Africana seedlings in terms of mineralization and it is relatively fast when compared with poultry manure, and the application of poultry manure has also it has positively influence the growth and development of T. Africana seedlings while poultry manure increased the digestible fraction (i.e crude protein) of the plant.

Lima bean (LB) (Phaseolus lunatus) is an underutilized legumein Nigeria and West Africa despite its numerous nutritional benefits. This study evaluated the proximate composition, phytochemical screening and antinutritional factors (ANFs) of three accessions of Lima beans; LB 001, LB 011 and LB 015 from the International Institute of Tropical Agriculture (IITA), Ibadan, Oyo State. All analyses were done using standard protocols. Statistical analysis was done using descriptive statistics. Result of proximate analysis revealed that LB 011 recorded the highest value for crude protein (25.70 0.06%), crude fat (3.10 0.05%) and crude fibre (3.20 0.06%) and moisture content (9.3 0.16%), LB 015 recorded the highest value for ash (3.90 0.04%), nitrogen free extract (60.35 0.20%) while LB001 gave the highest value for drymatter (92.30 2.50%).Phytochemical screening revealed presence of saponin, flavonoid and alkaloid in the three accessions of LB while anthraquinone and cardiac glycoside were absent in all the LB accessions. Results of ANFs showed that LB 001 recorde the highest value for alkaloid (56.67±5.78mg/g), LB 015 gave the highest value for tannin (93.33±2.89 mg/g) and saponin (61.67±2.89 mg/g) while LB 011 had the highest oxalate content (30±5.00mg/g). The study concluded that the three accessions of lima beans have high levels of crude protein, crude fat and ash and phytochemicals, which compared favourably with that of cowpea (Vigna unguiculata), a conventional legume. However, the ANFs present in LBneed adequate processing for their reduction and optimal utilization as a protein source for human and animals.

Bean sprout is used as vegetables. The present study investigated the effect of temperature and light on seed germination and sprout yield, and proximate (crude protein, crude fat, crude fibre, nitrogen free extract and ash) composition of sprout in Lignosus (Dipogon lignosus (L.) Verdc.) and Mung (Vigna radiata Wilczek) beans. Three temperatures (ambient, 25o and 30oC) and two light regimes; continuous dark, (CD) and continuous dark alternated by ½ hour light daily, (DAL) were used for seed germination and bean sprout yield. Data were collected 24, 48, 72, 96 and 120 hours after setting the presoaked seeds in the petri dishes. Of the temperature regimes, generally better seed germination and sprout fresh weight (yield) were observed at 25oC in Mung bean and 30oC in Lignosus bean. Germination and sprout yield were similar under CD and DAL. Both under CD and DAL, sprout yield was higher after 120 hours compared to 96 hrs after germination in both the beans. Proximate composition of dry seeds and their sprouts was also determined. Irrespective of species, crude protein content was significantly higher in sprout (average of 29.33%) than dry seed (average of 24.33%).Vitamin C was significantly higher in Lignosus bean sprout (20.93 mg 100g-1) compared to Mung bean sprout (9.52 mg 100g-1). This is the first world report on Lignosus bean sprout. It may be concluded that better sprout yield and good protein content were obtained at 25oC in Mung bean and 30oC in Lignosus bean after 120 hrs of germination irrespective of dark and light.J.
