    (2024-09-25) Dedo Adi Doreen; Oduro Ibok N.; Tortoe Charles
    Post-harvest loss of plantain peeks at senescence. Drying senescent plantain enhances its culinary applications. This study aimed to determine the biochemical and functional properties of foam-mat dried senescent plantain samples, and their respective powdered mixes prepared for baking ofam (an Indigenous spicy cake). The nutritional benefits of foam-mat dried senescent plantain, with its high vitamin C and total carotenoid content, make it a valuable addition to dietary interventions. Foam-mat dried plantain samples and their respective powdered mixes were evaluated for their proximate composition, vitamin C, total carotenoids, amino acid contents, water and oil absorption capacities, and least gelation concentration using standard methods. The products were predominantly carbohydrates (73.3g - 80.4g/100g) with low moisture contents (9.19 - 20.68 g/100g). Vitamin C and total carotenoids ranged from 17.42 mg/100g to 33.99 mg/100g and 3.4 to 7.2 µg/g respectively. The samples had appreciable amounts of calcium (78.90 - 175.18 mg/100g), magnesium (112.13 - 113/79 mg/100g), potassium (95.76 - 77.09 mg/100g), iron (17.65 - 12.76 mg/100g) and zinc (10.94 - 15.82 mg/100 g). The most abundant amino acids were phenylalanine, histidine, methionine and aspartic acid. Sample SPPFSCF exhibited the best gelation capacity (22 g/100 mL). The water absorption capacities of the samples were influenced by the flour type used. However, the variations in the oil absorption capacities of the powdered mixes were statistically insignificant. EAPFRCF absorbed the least oil (0.84 g/g) while SPPFSCF absorbed the most (0.94 g/g). Foam-mat dried senescent plantain and their powdered mixes have the potential for utilization in nutritional interventions. Its low moisture content will support a longer shelf life than the fresh overripe plantain.

    Effect of endosperm maturity on the physicochemical composition and sensory acceptability of coconut (Coco nucifera) milk and yoghurt
    (2023-10-27) Konadu Lydia; Dedo Adi Doreen; Acquah-Mensah John; Olu Fagbemi Ellen
    This study aimed to evaluate the effect of endosperm maturity on the physicochemical compositions and sensory acceptability of coconut milk, as well as to determine the effect of endosperm maturity and fermentation time on the physicochemical characteristics of coconut yogurt and its sensory acceptability, respectively. Varied coconut endosperm maturity (soft, medium, and hard) and fermentation time (6, 12, 18 and 24 h) were used to produce milk and yogurt. The physicochemical compositions and sensory acceptability of the samples were evaluated using standard methods. The physicochemical characteristics of coconut milk and yogurt were influenced by both endosperm maturity and fermentation time. Coconut milk produced from hard coconut endosperm was the most preferred and recorded the highest brix (3.31°), fat (6.71%), total solid (16.02%), and acidity (1.26%) levels. Coconut yogurt fermented for 6 h was the most preferred. Optimization of both coconut milk and yogurt processes could produce a commercially viable product.

    Management Perceptions of Waste Management in Ghanaian Hotels
    (2024) Bentil Linda Zipporah; Prof. Olu Fagbemi Ellen; Dedo Adi Doreen
    Waste management in the hospitality industry has become a critical environmental and operational challenge, particularly in developing economies where regulatory enforcement and infrastructure limitations hinder sustainable waste disposal practices. This study examines waste generation patterns, regulatory frameworks, existing waste management practices, barriers, and sustainable strategies in hotels, with a specific focus on Ghana’s hospitality sector. Using a systematic literature review approach, relevant academic studies were analyzed to synthesize key insights into the complexities of hotel waste management. The findings reveal that organic waste, single-use plastics, and hazardous materials constitute most of the hotel waste, with food waste being the largest contributor. While hotels in developed countries have adopted strict regulatory frameworks and advanced waste management technologies, compliance remains a significant challenge in Ghana due to weak enforcement, high compliance costs, and unreliable waste collection services. Additionally, low guest participation in recycling programs and inadequate infrastructure further exacerbate waste management inefficiencies. The study highlights that hotels implementing green procurement, AI-driven waste sorting, and circular economy principles have improved waste reduction outcomes and cost savings. Collaboration between hotels, government agencies, and waste management firms is essential to drive policy reforms, increase compliance incentives, and improve waste collection systems. This research contributes to sustainability literature by providing actionable insights into policy recommendations, industry best practices, and technological innovations for hotel waste management. Future studies should explore scalable and cost-effective waste solutions tailored to small and mid-sized hotels, ensuring wider adoption of sustainable waste management practices across the hospitality sector.

    Microbiological quality of vendored Waakye: comparative study of caregiver vendors and solo vendors
    (2024-09-27) Osanyogmor Grace; Dedo Adi Doreen; Olu Fagbemi Ellen Louise
    Ghana's thriving street food industry, popular for its convenience and affordability, struggles with ensuring food safety due to multiple influencing factors. This study examines the influence of childcare on the microbial quality of waakye, a popular street food in Ada. A comparative analysis was conducted between caregiver and solo vendors, sampling five vendors using convenience sampling. Waakye specimens were collected at the start and midpoint of sales, and microbiological quality was assessed using standard methods. An observational study was conducted to evaluate vendors' hygiene compliance. Observations revealed inadequate temperature control and hand washing facilities among vendors. Statistical analysis showed significant differences (p < .001) in total coliform, Escherichia coli, and Staphylococcus aureus counts between vending groups. Additionally, the microbial quality deteriorated significantly (p < .000) from the start to the midpoint of sales. Findings suggest childcare compromises the microbial quality of vendored waakye, emphasising the need for improved hygiene practices and infrastructure.

    Students’ Residential Satisfaction With Hostel Facilities In Universities In Ghana, A Study Of Aamusted-Kumasi Campus
    (2024) Tuglo Millicent Esinam; OlU Ellen. Fagbemi; Dedo Adi Doreen
    Purpose and Scope: Attempts to increase access to higher learning in Sub Sahara Africa have led to Universities’ efforts to provide and manage student accommodation on campus. Satisfying the users of hall facilities should be one of the main objectives of providing such a facility. The current study sought to assessstudents’ residential satisfaction in residence halls at Ghanaian University, AAMUSTED, Kumasi. Design/Methods: Using a mixed-method approach, the study adopted a descriptive research design. Quota and Convenience sampling techniques provided 200 respondents. Major data collection instruments included focus group discussions (FGDs), observations, and questionnaires designed under three attributes namely; Personal (in-room), Social amenities; and Management system.Result/Findings: Descriptive statistics using SPSS V.23 and thematic analysis revealed students’ Dissatisfactionwith specific facilities under Personaland Socialattributes that offer privacy, comfort, and recreation. Additionally, there was dissatisfaction with the provision of tables and chairs for room learning, utilities as well as services that ensured reliable security and cleaning.However,students “Dissatisfaction” with management's attitude and responses to their grievances and complaints in the halls in “repairing and replacement of gadgets or facilities ultimately resulted in a negative impact on student’s residential satisfaction.Practical Implication: The results of this study will help the university's hall administration enhance a few areas of the administration structure, most notably the association's dedication to facility maintenance and repairs. ConclusionIt was suggested, based on the aforementioned findings, that residence hall managers periodically interview students to get their feedback on the caliber of services they receive. In addition to having plants or generators available to replace power failures in the residence halls, university administration should also ensure a steady supply of electricity. Additional research ought to evaluate the degree of contentment experienced by students residing in privatehostels.
