Dabuwa is a dried stiff porridge made from fonio and maize in the ratio of 1:3, beef fat and spiced with fresh onion and caraway (black) seeds. It is a popular food indigenous to the Shuwa Arab nomads of North-eastern Nigeria. An attempt was made to modify dabuwa not only from maize but also from millet and rice. The cereal flours were supplemented with legume flours, the beef fat content was reduced, fresh onion and caraway seeds were replaced with a dried spice-mix of onion, ginger and cardamom. A 3×2×2×2 full factorial design was scaled down to a fractional factorial design of 3×2×2 which generated 12 runs. Supplementation (cowpea and soybean) was done at a constant level of 30%. Fonio was incorporated at either 12.5% (F1) or 22.5% (F2). Each formulation had the other cereal (maize, millet or rice) added at 57.5% (Ma1, Mi1, R1) or 47.5% (Ma2, Mi2, R2); while traditional dabuwa comprising of 25% fonio and 75% maize served as the Control. The blends and dabuwa were evaluated for functional and sensory properties, and proximate composition. Results indicated a general increase on water absorption capacity (216.76% to 270.34% of the blends) unlike oil absorption capacity (0.97ml/g to 1.09ml/g), and an enhanced bulk densities (0.74-0.86g/ml). Dabuwa samples enriched with soybean were shown to be denser in nutrients than those supplemented with cowpea, though no particular trend was observed. Moisture, ash, crude protein, crude fiber, fat, carbohydrate (by difference) and calorific contents of the blends varied significantly (p≤0.05) from 7.38 to 12.18%, 1.80 to 2.96%, 4.33 to 16. 29%, 1.62 to 6.59%, 2.45 to 9.57%, 53.66 to 82.90%, and 337.12-393.37kcal/100g respectively. Proximate composition of modified dabuwa varied thus:4.86-10.85%, 0.92-2.48%, 10.11-16.38%, 0.96-4.65%, 2.02-10.60%, 58.55-86.54%, and 351.03-421.17kcal/100g for moisture, ash, crude protein, crude fiber, fat, carbohydrate contents and calorific value respectively. Sensory scores revealed that rice- and maize-containing dabuwa were liked moderately, but millet containing dabuwa were neither liked nor disliked by the panelists. It was concluded that dabuwa could be prepared not only from maize, but also from rice or millet with legume fortification for enhanced nutrient density without affecting negatively the well known traditional sensory properties of the dabuwa.. Therefore, production and consumption of dabuwa should be re-popularized and its consumption patronized so as to provide macro and micro nutrients to the consumers and avoid the disappearance of a worthy age-old food product.

Objective: Ogi is a fermented cereal gruel produced from maize, sorghum or millet. The objective of the study was to investigate the effect of ginger and cinnamon on the proximate composition and sensory properties of corn ogi. Methodology: Ogi slurry was prepared from corn and fortified with 5% ginger, 5% cinnamon, 5% ginger: 5% cinnamon and 2.5% ginger: 2.5% cinnamon spices and 100% corn ogi as control. The samples were analyzed for proximate composition and sensory properties using standard methods. Results: The results obtained from this study indicated that there was an increase in the moisture, ash, protein and fat contents of corn ogi spiced with ginger and cinnamon and a decrease in carbohydrate content. These increases were observed to be significant (p<0.05) with corn ogi samples spiced with ginger than for cinnamon except for crude fiber which was higher in ogi spiced with cinnamon. Moisture content of the ogi samples ranged from 8.53-9.79%, crude protein 5.13-6.37%, ash 0.19-0.30%, crude fiber 0.29-0.81%, carbohydrate 78.93-81.64% and energy contents 387.77-391.98 kcal. The inclusion of cinnamon and ginger had no significant (p<0.05) effect on the sensory properties of the unsweetened spiced ogi samples. Mean scores obtained for unsweetened ogi samples were low. Upon sweetening with sugar, these scores were increased for all sensory attributes. Sensory evaluation of sweetened ogi samples showed that the control sample was more preferred for all sensory attributes and this was followed closely by sample ogi spiced with 5% ginger. Conclusion: This study recommends the use of ginger at 5% for the fortification of corn ogi which will result in ogi with sensory properties similar to 100% corn ogi. It also showed the potential of fortifying corn ogi with ginger and cinnamon, either singly or as a blend, to enhance the nutritional quality of corn ogi.

Background: Utilization of wild legumes has received prime importance in the recent past to compensate the scarcity of protein-rich foods as well as to tackle the protein energy malnutrition. Ripened split beans of Canavalia maritima devoid of seed coat and testa serve as traditional nutraceutical source for the coastal dwellers of Southwest India. Objective: The present study projects proximal and functional attributes of uncooked and cooked ripened split beans of C. maritima to be used in the preparation of functional foods. Methods: Proximal properties (moisture, crude protein, total lipids, crude fibre, carbohydrates and calorific value) and functional properties (protein solubility, gelation capacity, water-absorption, oilabsorption, emulsion qualities and foam qualities) of split beans were evaluated by standard methods. Results: Cooking did not significantly changed the crude protein, total lipids, ash, carbohydrates and calorific value, while it significantly increased the crude fibre. The protein solubility, water-absorption capacity, foam capacity and foam stability were significantly higher in uncooked than cooked beans. The cooked beans were superior to uncooked beans in least gelation concentration, low oil-absorption capacity, emulsion activity and emulsion stability. Conclusion: The functional properties of split bean flours were influenced by the proximal components like crude protein, total lipids and crude fibre. The energy-rich ripened split beans of C. maritima can serve as a new potential source for production of value added functional foods owing to their rich protein, rich carbohydrates, low-lipid and potential bioactive attributes.

Purpose – This paper aims to assess the potential of date fruit powder as a refined sugar replacer in rock buns to help promote and diversify the utilization of date fruit. Design/methodology/approach – Date fruit pulp was sun dried, milled into powder, sieved and its proximate composition determined. Refined sugar in rock buns was replaced with date fruit powder at 0, 50, 80 and 100 per cent levels. The samples were then subjected to proximate, mineral and sensory evaluation. Findings – Date fruit powder had 1.47 per cent crude fiber and was high in carbohydrate (82.15 per cent). Carbohydrate content of samples decreased (48.55-29.72 per cent), while crude protein (6.78-9.97 per cent), crude fat (22.74-33.66 per cent) and crude fiber (0-0.49 per cent) contents increased with an increasing substitution of date powder. Of all, 0 and 50 per cent substituted rock bun samples were the most preferred. Date powder significantly (p < 0.05) increased the potassium (0.55-1.57 per cent), calcium (0.08-1.08 per cent) and iron (0.53-0.625 per cent) contents of the samples. Originality/value – This research assessed the potential of date fruit powder as a replacer of refined sugar in rock buns, as it remains an underutilized commodity in Ghana. Replacing 50 per cent of refined sugar improved the nutrient composition of rock buns, thereby making date fruit powder a nutritious sugar replacer which could be used in pastry products. This when adopted would diversify the utilization of date fruits while providing good nutrition to consumers.

The objective of this work was to study the effect of seaweed (Eucheuma cottonii) our addition on physicochemical and sensory characteristics of an Indonesian-style beef meatball. Seaweed flour (SF) was added to meatball batter at 0% (CON), 2.5% (SF2.5), 5.0% (SF5) and 7.5% (SF7.5) in weight/meat weight (w/w) basis. Proximate composition (moisture, crude protein, crude fat, crude fiber and ash content), pH, cooking loss, hardness, water-holding capacity, instrumental color and sensory properties (color, texture, aroma, taste and overall acceptability) of the boiled meatballs were evaluated. The effect of seaweed our addition was very significant (P<0.01) on moisture, crude fat, crude fiber, ash, cooking loss, hardness, water holding capacity, lightness (L*), yellowness (b*) and all sensory properties, and was significant (P<0.05) on crude protein, pH and the redness (a*) of a boiled Indonesian-style beef meatball. The addition of seaweed flour at more than 2.5% resulted in darker meatballs, with less protein and fat, and a stronger seaweed aroma. The results suggest that seaweed flour could be added at 2.5% (w/w) to produce an Indonesian-style beef meatball with enhanced ber content.

Mango Seed

India is the largest producer of mangoes with 44.14 % of the total world production. The kernel obtained after decortication of mango stone can be utilized as a supplement to wheat flour. Present study was undertaken with the objective to study sensory properties and shelf life of Mango Kernel Flour (MKF) incorporated wheat crackers (baked food product). Mango kernel accounts for 9 % of total weight of mango fruit. Flour recovery from mango seed kernel is 80.6 %. Except for water absorption capacity, functional properties of MKF and wheat flour differed significantly. Sensory scores obtained for 20 % incorporation level was observed to be on par with the control. At the 15<sup>th</sup> day there was slight decrease but statistically significant difference was noticed between initial and 30th day for sensory scores of crackers. But both control and MKF incorporated crackers had acceptable sensory scores for all the parameters, indicating shelf life of one month. Less microbial load on MKF crackers at the end of 30 days of storage period may be attributed to the presence of polyphenols, which exhibits antimicrobial activity. MKF can be utilized as wheat flour supplement up to 20 % in crackers, with least effect on sensory properties and exhibited shelf life of one month.

Aim: To advance the creation of variety through food product development and innovation, a comparative study of custard products with Turmeric (Curcuma longa) and Pawpaw (Carica papaya) was done. Study Design: This study was made to fit into a one way Analysis of Variance. Place and Duration of Study: The research was carried out at the Department of Food Science and Technology laboratory, Federal University of Technology, Owerri, Nigeria, between March 2017 and August 2018. Methodology: Different ratios of corn starch to pawpaw or turmeric were used in the custard product while a commercial custard product was used as the control. The samples were evaluated for proximate composition, microbiological analysis, functional and sensory properties. Results: The water absorption capacity (1.44% to 1.64%), swelling index (5.27% to 6.77%), bulk density (0.68% to 1.55%) and gelation concentration (6.47% to 8.62%) of the turmeric treated custard and pawpaw treated custard were significantly different (P<0.05) from the control sample. The pawpaw treated custard had a higher protein and ash content compared to turmeric treated custard and control. With regards to the general acceptability of the custard products, the control was much accepted while the pawpaw sample was moderately accepted by the panellist. Microbial result showed that the pawpaw treated custard had an acceptable level of Streptococcus spp. The contamination level in the pawpaw treated custard, turmeric treated custard and the control were below the safety level recommended by International Microbiology Standard Limits for pseudomonas spp. Conclusion: The development of these custard products showed that pawpaw treated custard is acceptable and may compete favourably in the market since it has better aroma than some commercial custard present in Nigeria. It is also important to pay close attention to the handling and processing of these products so as to promote food product safety.

The resolution IV fractional factorial design was used to study the adsorption regularity of Cu coexisted with various pollutions (Zn, Pb, Cd, Ni, atrazine, malathine, et al.) onto the sediment. The study found that the main effect and the second-order interaction effect of ten pollutions concentration had significant influence on the adsorption of Cu on the sediment. The concentration of Cu was the critical factor to the promotion of the absorption capacity of Cu in sediment, the second-order effect played the critical role in restraining the absorption of Cu. The main effect of Cd, and the second-order interaction effect include Cd, had greatly inhibited the absorption of Cu in sediment, and the contribution was over 30%, which meant there was prominent antagonism between Cu and Cd. Fractional factorial design can provide a theoretical basis for the reveal of the adsorption mechanism between the different contaminants in the water environment pollution.
