Ogiri’ is a locally fermented product from oil seeds such as melon seeds (Citrullus vulgaris). It is commonly used as condiments to enhance the flavour of the variety of foods. This study was aimed at determining the influence of different wrapping materials on microbial load, proximate composition, physicochemical and sensory properties of indigenous fermented melon seeds known as “ogiri-egusi”. Melon seeds obtained from the local market were dehulled, wrapped in banana leaf, boiled and mashed. The mashed ‘ogiri egusi’ was separately wrapped using aluminium foil, paper, banana leaf, transparent and black cellophane and allowed to ferment for five (5) days. Daily pH monitoring of the samples was carried out while microbiological analysis and proximate composition of the fermented products were determined using Standard Methods while Sensory evaluation was carried out using a 9-point Hedonic scale. The sample wrapped with banana leaf had the highest total heterotrophic bacterial count (THC) of 6.08 log10 CFU/g), total coliform count (CC) of 4.88 log10 CFU/g, total Staphylococcal count (TSC) of 5.07 log10 CFU/g) and total fungal count (TFC) of 3.75 log10 CFU/g). On the contrary, ogiri-egusi wrapped with aluminum foil had the lowest THC (5.84 log10 CFU/g), TCC (4.39 log10 CFU/g), TSC (4.83 log10 CFU/g), TLC (3.61 log10 CFU/g) and TFC (3.39 log10 CFU/g). Staphylococcus sp., Micrococcus sp., Bacillus sp. and Lactobacillus sp., Aspergillus niger, A. flavus, Fusarium sp., Saccharomyces sp., Penicillium sp. and Candida sp. were isolated from the samples wrapped with different materials. There was a slight increase in pH with an increase in fermentation time in all samples  irrespective of the wrapping material. There were significant differences (P<0.005) in proximate composition and sensory scores of the samples wrapped with different materials. Ogiri-egusi wrapped with aluminium foil was most preferred based on sensory scores. Considering the results obtained from the microbial analysis, proximate composition and sensory properties of ogiri-egusi wrapped with different materials, aluminium foil is recommended as a wrapping material. This will enhance the microbial and aesthetic qualities of this locally fermented condiment product for improved utilization.

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 effect of replacing wheat flour with cocoyam (<em>Xanthosoma sagittifolium)</em> flour on the proximate composition, physical, sensory properties of cake were investigated<em>.</em> Baking trials were conducted at different levels of substitution (0, 20, 40, 50, 60, 80 and 100%). Cocoyam flour had higher values (p &lt; 0.05) in all functional characteristics evaluated except for emulsifying capacity. Cake weights and volume increased with increasing cocoyam flour substitution while volume index decreased. Protein and fat contents of cake samples decreased (p&lt; 0.05) with increasing levels of cocoyam flour substitution while ash and fibre contents increased. There was no significant (p &gt; 0.05) difference in crust colour of samples. In terms of textural preference, cake prepared from 100% cocoyam flour was significantly higher than 100% wheat cake. Utilization of wheat-cocoyam flour blends in composite cake preparation will be beneficial to the nutrition of vulnerable groups considering the higher ash and fiber contents of of composite cake, and reduced carbohydrate and fat contents than control.

The growing demand for honey in the market has led to the occurrence of the tampering honey with foreign substances and increases the production of artificial honey. Due to this concern, this study works on the physicochemical and microbial characterization of stingless bee honey. The physicochemical analysis showed that the honey possessed pH (2.51–3.26), free acidity (121.1 to 318.7 meq/kg), moisture (19.4–30.9%), electrical conductivity (0.33–0.69 mS/cm), ash content (2.75–4.31 g/100g), Hydroxymethylfurfural (HMF) content (35.4 to 461.7 mg/kg) and diastase activity (2.71 to 6.11 DN). Also, sugar profile of honey showed that the honey contained fructose (15.03–32.52 g/100g), glucose (12.17–34.55 g/100g) and sucrose (0.01–7.29 g/100g). The harvested honey, H1, and H2 have the highest potential to become an antibacterial agent to treat disease compared to commercial honey samples because they were active against Gram-negative bacteria. All analyzed samples were within the maximum limit of the quality criteria set by the Malaysian Kelulut Standard and Codex Alimentarius except for free acidity, HMF, and Diastase Number. All the data obtained is vital in order to create a specific statute for stingless bees honey in Malaysia that may help to protect the consumer from purchasing adulterated honey.

Fermented food condiments form an integral part of African diets as they supply nutrients with claimed medicinal properties. This research was designed to investigate the effect of period of fermentation on the microbial, mineral and proximate composition of fermented Parkia biglobosa seeds. The bacteriological, nutritional and sensory parameters were carried out on the raw, dehulled and fermented seeds. The result of the total bacterial counts showed that the raw seed had 3.67 log10cfu, there was a significant increase in the total bacteria count from 2.20 log10cfu/g in dehulled unfermented bean to 9.248 log10cfu/g at 96 hr of fermentation. The bacteria isolated were Bacillus subtilis (32 isolates), Lactobacillus plantarum (9 isolates), and Leuconostoc spp (3 isolates). The pH increased significantly from 4.57 in the raw seeds to 8.40 at 96 hr of fermentation. The titratable acidity decreased from 0.179N in the raw seeds until it got to 0.0313N at 96hr of fermentation. The proximate composition on dry mass basis showed that ‘iru’ fermented for 48hr had the highest protein content of 41.023%. The carbohydrate decreased from 42.153% in the raw seed to 20.733% at the end of fermentation. Four of the minerals; lead, cadmium, cobalt and nickel were detected in the raw seeds but were no longer available after dehulling. Phosphorus, sodium, calcium and potassium increased during the fermentation period. The sensory result showed that the intensity of growth on the surface of the fermenting bean increased. Moreover, the sensory score on the texture showed that the seed became softer as the fermentation progressed. The colour became darker and the ammonia odour became more pungent. The overall-liking showed a significant increase as the fermentation progressed where the panelist preferred the product fermented for 72hr. The result from this study revealed that the best time for fermentation of Parkia biglobosa seeds to produce good quality iru was between 48hr and 72hr.

Water Melon

Water melon (citrullus lanatus) is a flowering plant species of the Cucurbitaceae family. It is- rich in an amino - acid called citrulline and may help move blood through the body and widely used as flavouring agent and also contributes substantially towards obtaining a balanced diet. This research was aimed to evaluate the proximate and anti nutritional factors of the plant to ensure human and animal food security. The proximate composition was done by soxhlet extraction, AOAC, Kjeldhal and other standard procedures while anti nutrients were analysed using standard procedures. The results of the research revealed the proximate composition of the water melon seeds such as moisture content, crude protein, lipids, ash content, crude fibre and carbohydrate. Low moisture content (5.20±0.003) high proteins (17.844±0.012) and lipids (18.208± 0.004) with others detected in moderate amount was obtained. Anti - nutritional factors such as oxalate, phytate, cyanide, nitrate, and tannin were also analyzed which revealed low oxalate content (0.005± 0.003) with moderate amount of phytate (4.366±0141), nitrate (47.309±0.539) and cyanide (41.510±0.138). Therefore water melon seeds might be vital in maintaining an optimum nutritional status to avoid malnutrition, morbidity or mortality.

Local Aba made melon shelling machine type I (sample B) and improved Aba made melon shelling machine type 2 (sample C) were used to shell melon seeds and compared with hand shelling method (sample A). The shelling efficiency, quality of shelled melon seeds, functional properties of the seed flours and sensory properties of egusi soups prepared from the melon seeds were determined. The results revealed that sample A gave the highest shelling efficiency of 92.25%, followed by sample C (90.42%) and the least was sample B (80.85%). For the quality of shelled melon seeds, sample A gave the highest score of 95.88%, following by sample C (94.46%) while sample B gave the least score of 79.84%. There was no significant difference (P> 0.05) in the proximate composition of the melon seeds obtained from the three shelling methods (samples A, B and C). There were no significant difference (P>0.05) in all the selected functional properties between samples A and C while sample B had significantly lower values in all the functional properties that were studied. The mean scores for overall acceptability of egusi soup prepared from the shelled melon seeds were; samples A (7.95), sample B (6.02) and sample C (7.72). Functional and sensory properties of the melon seeds shelled by the improved Aba made melon shelling machine type 2 compared favourably with the hand shelled melon seeds. Hence, it can be recommended for commercial operations to meet the demands of industrial and commercial markets.
