Phase 1: Problem Analysis and Solution Drafting
Phase 1 of the Sweet Cashew Team’s project spanned one week at the University of Nigeria, Nsukka (UNN) in Enugu State, Nigeria. During this period, our team conducted a comprehensive analysis of the astringency problem in processed cashew nuts, identifying its causes, such as high tannin and phenolic compound content, and exploring how these compounds contribute to the bitter taste. We engaged with Mr. Daniel, an industry representative from Vertex Agro Limited, who provided critical insights into the processing challenges and requirements for improving cashew kernel quality.
In conclusion, Phase 1 culminated in the development of draft solutions, including chemical treatments and enzymatic processing to reduce astringency. These proposed solutions were presented to the ABC team at UNN, outlining a strategic approach to enhance the sensory quality of cashew nuts for Vertex Agro Limited’s local and international markets.
Phase 2
Completed Activities
Literature review, Industrial Visit, Sample Acquisition, and Laboratory Trials.
What is being Done
Drafting a proposal for a device to detect tannins and moisture content in cashew nuts. Researching Near-Infrared (NIR) spectroscopy for the development of the detection device. Conducting laboratory testing of proposed solutions.
What is yet to be Done
Analysis of laboratory test results, Preparation and recommendation of the best solution, Finalizing the draft proposal for the tannin and moisture detection device and Compiling a comprehensive report.
Phase 3
Presentation of the findings and deliverables at Zambeze University in Mozambique.
Project Progress
Completed Tasks
Completed tasks include project initiation during the opening meeting at the University of Nigeria, Nsukka, planning project activities, and conducting a comprehensive analysis of the astringency problem in cashew nut processing.
Tasks in Progress
Ongoing tasks include drafting a proposal for a device to detect tannins and moisture content, researching Near-Infrared (NIR) spectroscopy for the device, and conducting laboratory testing of proposed astringency removal solutions with Vertex Agro Limited.
Next Tasks
Finalizing the analysis of laboratory test results, recommending the best astringency removal solution, completing the device proposal, and delivering a comprehensive report to Vertex Agro Limited and stakeholders.
