This study presents an extensive analysis of the research landscape concerning the application of computational and mathematical techniques in cocoa farming from 2000 to 2020. The methodology comprises a two-stage process: a bibliometric analysis of 1,886 peer-reviewed documents and a concept-centric review of 734 investigations explicitly focused on cocoa or its derived products. The main findings reveal contributions from various scientific disciplines, such as Chemistry, Biology, Social Sciences, Econometrics and Finance, Health, and Computer Science. The study proposes a Cocoa Sustainable Food Value Chain framework, emphasizing research applications in genetic improvement, machinery optimization, food composition health implications, and crop yield enhancement. An emerging research area focuses on developing machine learning techniques to address challenges in cocoa farming, such as post-production, bean quality, cocoa ripeness, pod counting, crop yield estimation, bean fermentation optimization, organoleptic recognition, and cocoa machinery industrialization. The study uncovers four research gaps related to computational and mathematical technique implementations that could provide value to smallholder cocoa farmers: (i) optimal cocoa aggregation and distribution management, (ii) development of user-friendly high-tech solutions, (iii) agricultural technology adoption, and (iv) evaluation of policy impacts. This research makes three significant contributions to the body of knowledge. First, it expands agri-food supply chain concepts by incorporating sustainability and proposing a theoretical framework tailored to the cocoa extended value chain. Second, it identifies the underdevelopment of ICT and IoT solutions supporting computational and mathematical techniques for cocoa production management. Third, it underscores the necessity to develop and transfer high-tech tools to enhance Good Agricultural Practices. This research emphasizes that the cocoa food core chain requires a digital transformation centered on smallholder farmers to improve the Cocoa Sustainable Food Value Chain
