The nutritional and mycoflora changes in dried African yam beans (Sphenostylis stenocarpa) were investigated during a storage period of twenty weeks. The result of the proximate analysis (g/100 g) showed that the following moisture content decreased from 11.15-9.80, fat 1.25-0.49, crude fibre 6.18-2.64, crude protein 77.92-62.14 while the ash content increased from 3.20-3.78, carbohydrate content 0.36-18.32. The mineral analysis (mg/100 g) showed a decrease in all parameters investigated, sodium (Na) 2.57-1.35, potassium (K) 42.26-31.75, calcium (Ca) 21.45-12.56, magnesium (Mg) 27.75-20.72, iron (Fe) 0.25-0.12, zinc (Zn) 0.06-0.05, copper (Cu) 0.03-0.03, phosphorus (P) 32.08-22.03, manganese (Mn) 0.11-0.06, chromium (Cr) 0.002-0.001. Lead (Pb), cadmium (Cd) and nickel (Ni) were not detected. Five fungi comprising four genera were isolated using direct plating, washing and dilution methods on Potato Dextrose Agar (PDA), and identified using their cultural and morphological features with reference to standard procedures. The fungi isolated were Aspergillus niger, Aspergillus flavus, Penicillium sp., Mucor sp. and Phytophthora palmivora. It can be concluded that storage encourages proliferation of mycoflora thereby leading to reduction in the nutritional and mineral composition of the stored sample.

The proximate analysis of the fruit sample that homogenously sampled from the wild was taken and quartered to get appreciable weight fit for analysis. Due to it perishable nature the quartered sample for each of the fruit was stored in an air tight container and kept in the refrigerator at a temperature of about 4°C. For the determination of the nutritional composition, parameters which include their proximate, minerals, and vitamin C were quantitatively determined while the anti-nutrient composition were qualitatively and quantitatively analyzed. Compared to ackee’s apple, monkey cola was found to consist of 64.41% moisture content, 1.69% ash, 10.21% crude fibre, 1.25% crude fat, 4.44% crude fibre, 18.06% carbohydrates while ackee’s apple consist of 73.21% moisture, 1.49% ash, 9.38 % crude protein, 13.98% crude fat, 2.08% crude fibre, 0.86% carbohydrates and 4.45% of vitamin C. The mineral analysis for both samples was quantitatively determined using Atomic Absorption spectrophotometer (AAS). The minerals determined for ackee’s apple and monkey cola were magnesium which was 1391.65 ppm, calcium 628.23 ppm, sodium 506.96 ppm, potassium 3976.14 ppm, iron 1.0 ppm, copper 5.00, zinc 4.00, cobalt 3.0 and phosphorus 2616.90 ppm the iron however, was not detected. Ackee’s apple on the other hand, consist of magnesium 498.01 ppm, calcium 478.56 ppm, sodium 398.80 ppm, potassium 4970.18 ppm, copper 2.00, zinc 5.00, cobalt 3.0 and phosphorus 373.84 ppm. The qualitative screening of the anti-nutrients revealed the absence of phenol from both fruit samples while tannins were present only in the monkey cola. The flavonoids, phytic acid and oxalate were quantitatively determined to be 1240 mg, 625 mg and 155 mg for Monkey kola and 640 mg, 340 mg and 65 mg for Ackee’s apple.

The effect of storage materials on the quality of tomato powder was studied. Fresh, firm and matured red tomatoes were washed, sorted and sliced to a uniform thickness of 5mm. The sliced tomatoes were pre-treated by dipping in 1% calcium chloride (CaCl2) and 0.2% potassium metabislphite (KMS) solution for 10 minutes at room temperature. 200g each of the sample was dried at temperatures of 600C until equilibrium moisture content was attained. The dried tomatoes were ground into powder and stored in Black polyethylene [BPE], White polyethylene [WPE], and Laminated Aluminium Foil [LAF] pouches for 6 weeks. The moisture content, crude protein, crude fibre, fat, total ash, and vitamin C of the tomato powder were determined using the method prescribed by AOAC. The carotene contents were determined by HPLC. The proximate analysis was repeated after 2 weeks, 4 weeks and 6weeks of storage.  There was an increase in moisture content and ash content after 6 weeks of storage while a decrease in value of protein, fat and vitamin C content occurred after the storage period. All the parameters measured were best retained by the laminated aluminium foil (LAF) compared to black polyethylene (BPE) and white polyethylene (WPE) packaging material for the entire period of the study.

Phytochemical and nutritional potentials of various parts (leaf, stem and root) of Talinum triangulare were evaluated using standard techniques. Analysis of Variance (ANOVA) was employed in data analysis. All the parts of the species were found to contain nutrient compositions in varying levels. Dry matter and carbohydrate were highest in the stem (91.69±0.12 and 68.66±0.01) respectively. Moisture, ash content and crude fibre were highest in the root (9.78±0.04, 17.53±0.11and 15.32±0.03) respectively while ether extract and crude protein were highest in the leaf (1.09±0.01 and 17.72±0.17) respectively. The results showed also varying quantities of the phytochemicals in the leaf, stem and root with some parts lacking some of the phytochemicals. The leaf contained the highest percentage of all the phytochemical investigated alkaloid, flavonoid, tannin, sterol, Terpenoid, phenol and saponin (0.47±0.01, 0.26±0.00, 0.36±0.07, 0.03±0.01, 0.42±0.02, 0.02±0.01and 0.68±0.05 respectively. The root lacked sterol and phenol while stem lacked only phenol. The leaf, stem and root lacked cyanogenic glycoside. The results have indicated that these parts of the Talinum triangulare investigated are very nutritious and possessed bioactive compounds that could be extracted for the manufacture of new drug, food supplements and also be used in ethnomedicine for the treatment of diseases.

This study was conducted to evaluate the suitability of soaked <em>Bauhinia monandra</em> (Kutz) seed as alternative protein source for <em>Clarias gariepinus</em> and to determine cost of feed compounded. The proximate analysis of the diet (crude protein, crude fibre, ash, moisture content and lipid) were determined using AOAC (1980). Data for each parameter was subjected to one way analysis of variance (ANOVA) while means of various results were compared at 5% level of significance. A preliminary study was conducted to determine the best processing method that reduced anti-nutrients to the minimum level without impairing nutrients composition. Boiled, toasted and soaked seeds were used. <em>Bauhinia</em> seeds soaked for 96 hours had least concentration of anti-nutrients. The experimental diets was formulated to contain soaked <em>Bauhinia</em> seed meal (SBSM) at levels of 25%, 50% and 75% inclusion (Diets 2, 3 and 4 respectively)  with two diets acting as control (Diets 1 and 5). All diets were isonitrogenous (40% crude protein) and isocaloric (3212kcal/kg). A 12 weeks feeding trial was conducted using juveniles which were randomly distributed into 12 improvised non-recirculatory and semi-flow through indoor plastic tanks (52cm X 34cm X 33.5cm) at a stocking rate of 10 fish per tank and three (3) replicates per treatment. The experimental design was complete randomized. The fish were fed at 5% body weight, twice daily. Diets with higher inclusion levels of SBSM (diets 3 and 4) significantly depressed growth performance of fish. The variations observed in the Specific Growth Rate (SGR), Feed Conversion Ratio (FCR), Feed Efficiency Ratio (FER) and Protein Efficiency Ratio (PER) were associated with the anti-nutrients present in the diets, these parameters reduced with increasing levels of SBSM in the diets of fish. Based on the relative cost of diets per unit weight gain and protein gain, diet 2 (25% SBSM) was most economical. The results suggested that SBSM can be used to substitute up to 25% levels of dietary protein in <em>C. gariepinus</em> juveniles without significant reduction in growth.
