ABSTRACT The ability of leaf powder and leaf extract of Ocimum gratissimum plant to preserve tomatoes (Solanum lycopersicum) from early spoilage was investigated in this study. Mixed cultures of tomatoes purchased from a retail outlet in Ogun, Southwestern Nigeria, were treated with the powder and some with the leaf extract of Ocimum gratissimum plant and observed for preservation or spoilage for 30 days. The plant powder gave positive preservation results wh...
This study evaluated the thermo-physical and rheological properties of Ogi produced from varieties of sorghum with different soaking period (12, 24 and 36 hrs.). Sorghum grain steeped for 12, 24 and 36 hrs. was processed into Ogi making use of the traditional method and subsequently dried at 55oC. The Ogi powder obtained was analyzed for functional, thermo-physical, rheological properties and the consumer acceptability was also carried out. The results showed that the bulk density ranged from...
ABSTRACT The proximate and sensory characteristics of cookies from wheat and tiger nut chaff flour blend. Tigernut chaff was obtained, incorporated into wheat flour in the ratio (90:10, 80:20, 70:30, and 60:40). Cookies was produced from the blends using standard method. The cookie samples were analyzed for the proximate composition and sensory properties. The proximate composition showed the values for Protein, fat, fibre, ash, moisture, and carbohydrate ranged between 8.11 to 9.98, 7.59 to ...
ABSTRACT The research evaluated the effect of soaking period on the functional properties of ogi produced from selected maize varieties (B2W, E1Y, N6W and R6Y). The maize varieties were steeped for 0, 12, 24 and 36th hour respectively and processed into ogi making use of the traditional method and thereafter dried at 550C. The ogi powder obtained was analyzed for functional and proximate properties. The result showed that the bulk density ranged from 0.80 – 1.14g/ml. Sample N6W soaked 12th ...
ABSTRACT Well water samples were collected from different household wells in Ifedapo Estate in Abuja community of Ikorodu Local Government Area, Lagos State, Nigeria. The samples of the well were analyzed for their physiochemical properties. The physiochemical properties of the water samples were analyzed using standard methods. The pH and Temperature ranged from 6.41-7.11 and 26.79-27.370C respectively. The bicarbonate and sulphates value were in the range of (28.41-31.41mg/l) and (17.42-28....
ABSTRACT Avocado (Persea Americana) paste was utilized to substitute wheat (Triticum aestivum) flour as fat replacer in the production of cake. This study examined the effect of avocado paste substitutions at various proportions in production of cake. The proportions were 100% wheat flour, 95:5%, 90 :10%, 85 : 15%, 80 : 20%, 75 : 25% and 70 : 30% avocado paste. Colour analysis and texture of the cake was evaluated. Results shows L*, a* and b* value of the cakes ranged from 48.56-54.96, 4.83-6...
ABSTRACT The study investigated the chemical changes inAfrican Star Apple (Chrysophyllum albidium) fruits prior to onset of rains and during the rainy season, with the aim of ascertainingits optimum consumption quality. The fruits were harvested from the School of Agriculture and Agricultural Technology, Federal University of Technology, Akure. Chemical analysis was carried out on the edible parts of the African star apple fruit(both the pulp and whitish seed coat). The result showed signific...
ABSTRACT Cookies were produced from wheat, sorghum, and defatted coconut flour blends to determine their potentials in cookie manufacture. Eight Cookies formulations were produced and they were evaluated for their proximate, physical, mineral, colour and sensory properties. The result showed that the moisture content ranges from 7.10 to 10.89%, ash content ranges from 0.88 to 1.15%, protein content ranges from 9.18 to 12.25%, crude fat ranges from 9.59 to 11.00%, crude fibre ranges from 2.7...
ABSTRACT This study was carried out to investigate the characterization and utilization of guava flavour concentrate produced from two guava cultivar using simple distillation technique for the flavor extraction. The physical properties of the flavor concentrate were determined and then utilized in the formulation of guava drinks with three different clouding agents (gum Arabic, garri aliquot and cheese-whey). The guava drink samples were also evaluated for different quality attributes whic...
The greatest problem consumers encounter with soy milk remains its very short shelf life due to microbial activity. The combination of different preservation methods may just be the solution to the problem. The synergistic effect of citric acid and sodium benzoate preservatives at various concentrations within their maximum permissible levels along with pasteurization, on the microbial keeping quality of home- made soy milk stored at ambient temperature was therefore, studied. This is with ...
The work was done to determine the effects of baking temperature on the proximate, micronutrient, microbial and sensory properties of bread. The breads were baked at four different temperatures of 190, 200, 210 and 220 0C for BT1, BT2, BT3 and BT4 respectively. The protein ranged from 10.53% to 12.42% and a significant (p < 0.05) difference existed between the samples. The crude fibre ranged from 1.50% to 1.70% and a significant difference existed between samples BT1, BT2, BT3 and BT4. The fa...
