Shelf Life Study and Quality Attributes of Cocoyam Chips

The study was carried out to determine changes in the quality indices (levels of peroxides values, acid values, pH and colour) of cocoyam chips and microbiological safety (bacterial, yeast and mould counts) of cocoyam chips as influenced by temperature during storage period of fried cocoyam chips. Cocoyam tubers were processed into chips of 3mm thickness; the slices were then fried at a frying temperature of 170°C in a shallow pot for 7 minutes and was packaged in polyethylene bags and stored under room and refrigerator temperature. The results showed that there was significant difference (p≤0.05) between quality indices, microbiological safety and storage temperature and packaging materials. From week 0-5, peroxide values of samples stored under refrigeration temperature were found to be low, ranged from 3.39 - 11.58 meq kg-1, while the samples stored in the room temperature were found to be higher 3.81 - 12.87 meq kg-1. Acid values were also found to be low in the samples stored in the refrigerator, ranged from 5.79 - 16 3.34mg/g and the samples that were stored in the room temperature ranged from 9.94 - 24.05mg/g. The samples stored under refrigeration temperature had low bacterial counts ranged from 5.0 x 101 - 6.2 x 101 cfu/ml while samples stored in the room temperature had higher bacterial counts, ranged from 9.0 x 101 – 74 x 101 cfu/ml. Yeast and mould counts in samples stored under refrigeration temperature ranged from 4.0 x 101 - 32 x 10 cfu/ml while the samples that were stored in room temperature had higher counts, ranged from 3.0 x 10 – 38 x 10 cfu/ml. pH ranged between 6.88 - 7.02 for both samples during storage period. The results showed that storage temperature and properly sealed packaging material has effect on the above parameters that were determined. There were also colour changes during the storage period

Original article - DETERMINATION OF INDIGENOUS AND FOREIGN ALCOHOLIC BEVERAGES’ LEVELS IN URINE BY QUANTITATIVE INFRARED SPECTROSCOPY

The comparative levels of indigenous and foreign alcoholic beverages in the urine of 24 University students after drinking a cup or shot of the beverages have been reported. The Fourier Transform infrared spectroscopy was used for the analysis. From the results, the percentage content of alcohol (%v/v) in burukutu, palmwine, beer, Ogogoro, gin and ethanol (standard) were 3.2, 6.8, 7.0, 40.0, 41.0 and 96.0 respectively. Similarly, the average levels of alcoholic beverages in the urine (mg/dL) of the students were 120, 200, 210, 220 and 230mg/dL respectively. In conclusion, the present work has shown that there is a relationship between the levels of alcohol consumed and those excreted. Secondly, the study has provided a scientific basis that some of our local beverages such as palmwine, and ogogoro can serve as good substitutes for some of the foreign beverages such as beer and gin respectively

Modification, Fabrication and Performance Evaluation of Insulated Box for Post-Harvest Handling of Fish

In order to address the challenges associated with postharvest handling of fresh fish, Nigerian Stored Products Research Institute (NSPRI) developed an insulated transportation mechanism named Ice Fish Box™ which has a capacity of 18 kg of fish and ice. However, capacity and ease of movement was encountered in the developed box leading to modification using a smaller box (inner box) of dimension 495 mm×340 mm× 340 mm fitted into a bigger box of dimension 540 mm×360 mm× 360 mm and a trolley on wheels using human muscle power for ease of movement. The construction was carried out using standard procedures and all materials used were sourced locally. Results of its performance tests indicated that the modified box can carry approximately 60 kg of fish and ice at full load and the trolley can carry load of up to 120 kg of stacked boxes and swerves easily at angle 45º.  It is expected that these modifications would allow for more storage of fish and ease movement on all terrains as handlers mostly women find it almost difficult in moving the earlier designed insulated box around. &nbsp

Role of healthcare in childbearing decision-making of WLHA in Nigeria: Application of PEN-3 cultural model

Healthcare experiences among women living with HIV/AIDS (WLHA), determine their utilisation of sexual and reproductive health services, which ultimately influences their decisions on childbearing. This study aimed to understand the importance of healthcare support in the childbearing decision-making processes of WLHA, and its impact on eliminating new paediatric HIV infections. We conducted in-depth interviews between July and August 2012 with 15 WLHA receiving clinical HIV care at a teaching hospital in Lagos. Using PEN-3 cultural model, as a guide we explored perceptions of healthcare support pre- and post-partum. Findings indicate that faith in God for the delivery of a healthy child is significant during the pre-partum period, while the advice of healthcare workers concerning childbearing and access to available healthcare services carry more weight post-partum. Our findings have important implications for HIV treatment and care programmes geared towards WLHA considering childbearing, and ultimately the UN Global plan to eliminate mother-to-child transmission of HIV, as we move towards the 2030 agenda for sustainable development
