Nutritional and Functional Characteristics of Senescent Plantain Powder Mix
(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.

Customer engagement and purchase intention in live-streaming digital marketing platforms
(Routledge, 2021-03-12) Prince Clement Addo; Jiaming Fang; Andy Ohemeng Asare; Nora Bakabbey Kulbo
The lack of human and social cues and customer engagement impedes traditional e-commerce until the birth of social commerce. This study investigates how customer engagement in live-streaming digital marketing affects purchase intentions. The results of 1726 datasets from two e-commerce platforms suggest that customer engagement is significantly associated with followership and purchase intention in live-streaming digital marketing. Whiles price is a significant moderator, its effects become insignificant on their purchase intentions once consumers become followers. The results highlight the positive impacts of social elements, including likes, chats, visits, and exposure time in social commerce towards transactional (purchase) and non-transactional (followership) benefits. Finally, the paper introduces a new perception of measuring customer engagement in live-streaming digital marketing and calls for further research into this new paradigm of social commerce to promote business and service provisions even with the restrictions of COVID-19.

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.

COVID-19: fear appeal favoring purchase behavior towards personal protective equipment
(Routledge, 2020-04-16) Prince Clement Addo; Fang Jiaming; Nora Bakabbey Kulbo; Li Liangqiang
The 2019 novel coronavirus is a non-segmented positive-sense RNA virus belonging to the Coronaviridae-Nidovirales family. We examined the swings in purchase behavior following the outbreak of the COVID-19 in Wuhan, China, and across the world based on the theory of fear appeal. We gathered published statistics (suspected, confirmed, and fatality) on the COVID-19 alongside the purchase of personal protective equipment to examine the swings in online purchase behavior. With a serial mediated analysis, we established that fear appeal is associated with the sharp dynamics in the online purchase as related to the COVID-19. The results confirmed that fear appeal promotes social presence in anticipation of seeking affection, acceptance, and social information. This feeling is a precondition for developing e-loyalty, which promotes purchase behavior. Even though our variables might not be conclusive enough, we believe the findings are fundamental to understanding the swings in the purchase trend in this and any similar situations.
