Gari fortified with Bambara Groundnut Flour (BGF) was assessed for its proximate composition, functional properties, sensory evaluation and Rheological properties. Four samples: 100% gari (coded SLY), 90% gari with 10% BGF (coded ATS), 85% gari with 15% BGF (coded FEA), and 80% gari with 20% BGF (coded ROT) were examined for the parameters listed above. The proximate analysis showed that the protein content ranges between 0.98-4.68%, fat content 1.10-2.60%, ash content 1.82-2.90%, crude fibre 2.30-2.42%. This showed an increase on addition of BGF while the carbohydrate content ranges between 78.20-83.5 %, moisture 11.60-12.6% and acidity 0.40-0.60, all showed a decrease in value on adding BGF. Rheological value showed that the peak viscosity ranges between 106.17-177.17, trough viscosity 98.33-161.00, breakdown 7.83-16.71, final viscosity 150.50-251.67, set back 52.17-90.67 and pasting time between 6.87-6.93. All these varied inversely with the quantity of BGF added. Pasting temperature showed slight variation which was not dependent on the amount of BGF added. It ranges from 79.2-80.02 °C. Sensory evaluation showed that there were significant differences in the samples examined.

Background: In recent years, a new everbearing strawberry cultivar, ‘Summertiara’ was cultivated to supply the strawberries in pre-harvest season from July to October in Japan. For highly research and development of processing of this cultivar, ‘Summertiara’ berries, the objective of this study was to characterize these berries, with relation to chemical parameters, total phenols, total flavonoids, total vitamin C, and total anthocyanins, and was to investigate the solubility and the stability of anthocyanins from the berries. Moreover, the functional properties such as antioxidative activity, active oxygen species scavenging activity, and antihypertensive activity were also evaluated.Methods: Chemical analysis, colour measurement, and sensory evaluation of new everbearing strawberry cultivar, ‘Summertiara’ berries were performed. Next, the solubility of anthocyanins from the berries and stability of these against pH, temperature, and an incandescent lighting were investigated. Moreover, functional properties of the extracts prepared from berries were elucidated using 5 different methods.Results: The contents of water, proteins, lipids, carbohydrates, and ash were the same as those of other cultivar berries. The sugar-acid ratio in the berries was low; these were acidulous. By sensory evaluation, the main factors were vivid red colour, aroma, and acidity. The berries were rich in phenols, flavonoids, vitamin C, and anthocyanins. The anthocyanins of the berries became unstable by heat treatment and light exposures such as visible rays. On the other hand, the extracts prepared from the berries showed the functionalities such as antioxidant activity, active oxygen species scavenging activities, and antihypertensive activity.  Conclusions: The strawberry cultivar, ‘Summertiara’ berries were the most suitable for processing ingredient of strawberry-derived products with superior health promoting functionalities.Keywords: Summertiara, everbearing strawberry cultivar, characterization, sensory evaluation, color and storage, functional property

Ogi was produced from composite flour of fermented Acha, roasted Soybean and Carrot.  The raw materials were blended in varying proportions. Proximate composition, functional properties and sensory characteristics of the formulated Ogi samples were evaluated. The results of the proximate composition showed a significant increase in moisture (5.36% to 9.94%), protein (3.94% to 16.98%), fat (1.89% to 10.23%), crude fiber (1.80% to 3.12%) and ash (0.35% to 0.99%); while a decrease was observed in carbohydrate (86.66% to 58.74%) with increase in supplementation with roasted Soybean flour and constant addition of carrot flour along with the milk flavor. The functional properties showed significant increase in foam capacity (5.99% to 7.97%), Swelling index (2.46 v/v to 3.08 v/v) and Least gelation capacity (8.10% to 14.0%); while a decrease was observed in bulk density (0.84 g/mL to 0.72 g/mL), water absorption capacity (1.40% to 1.10%) and foaming stability (3.39% to 2.79%). Sensory characteristics result revealed that there was no significant difference (p<0.05) in aroma and overall acceptability with increasing incorporation of roasted Soybean flour and constant addition of Carrot flour with milk flavor. Aside the control sample (containing 100% fermented Acha flour) there was preference for Sample C (70% fermented Acha flour: 15% roasted Soybean flour: 10% Carrot flour: 5% Milk flavor) and Sample D (60% fermented Acha flour: 25% roasted Soybean flour: 10% `Carrot flour: 5% Milk flavor) in terms of color (6.65 and 6.25), taste (6.95 and 6.35), aroma (6.45 and 6.30), mouth feel (6.10 and 6.35) and overall acceptability (6.50 and 6.50) respectively, among the blend formulations. Supplementation of fermented Acha with roasted Soybean and Carrot flour considerably increased the protein and fat contents of the blend; hence Soybean should be used for supplementation of cereal based product in order to improve their nutritional composition.

Extract Solution

The study determined the effect of Cinnamon (Cinnamonum verum) bark extract solution on proximate composition and sensory evaluation of smoke-dried catfish stored at ambient temperature (37+2oC) for 28 days. The experimental treatments are the control, 0.5%, 1% and 1.5 %( w/v) cinnamon bark extract solutions. Thirty-nine fish of average mean weight of 24.87+1.25g were gutted, washed and randomly assigned to the treatments. Thereafter, the fish were soaked into the treatments for 30minutes and later hot smoked for 12hours. After smoking, the fish were stored in boxes and placed on laboratory table for one month. The catfish Clarias gariepinus treated with 1% solution of Cinnamon bark extract had the highest moisture content with mean value 13.65+0.82%, followed by 6.93+1.66% recorded in fish sample treated with 1.5% solution of the extract, lowest percentage crude protein content 38.15+0.82% was observed in fish treated with 1% concentrate of the extract and percentage carbohydrate content indicate that the control have the lowest carbohydrate content with mean value 1.92+0.01% which is significantly different (p<0.05) from other treated sample while sample treated with 1.5% solution of the Cinnamon bark extract have the highest percentage carbohydrate with mean value 15.73+1.64%.Sensory evaluation was also assessed using 7-point hedonic scale and reveals that the smoked catfish retained very good score for appearance, colour, flavour, texture and general acceptance after 28days of storage and the overall acceptability mean score in fish treated with 5g and 15g cinnamon bark extract solution indicate the product is being generally accepted (2.87+0.59%) and (2.34+0.56%) respectively. Cinnamon (Cinnamonum verum) bark extract solution could be used to protect stored smoke-dried catfish from loss of nutritional value and general acceptability thus limiting economic loss and possible health risk to consumers.
