Formulation of Functional Food Supplements: Case Study of Manufacturing Process Optimization at ‘Sarepta Production’, Burkina Faso

Introduction: In the context of promoting local resources and achieving food sovereignty, plant-based food supplements play a key role. However, their production often remains artisanal, making them prone to contamination and quality inconsistency. Objective: This study aimed to harmonize and standardize the manufacturing practices of four dietary supplements produced at the “Sarepta Production” unit in Ouagadougou, Burkina Faso, by integrating Good Manufacturing Practices (GMP) and Good Hygiene Practices (GHP). Methodology: Standard Operating Procedures (SOPs) were developed for each stage of the production process. Microbiological analyses were carried out on three successive batches at Agence Nationale pour la Sécurité Sanitaire de l’Environnement, de l’Alimentation, du Travail et des produits de santé (ANSSEAT) using standards established by the International Organization for Standardization (ISO standards) to assess sanitary quality. Results and Discussion: The results showed a progressive reduction in total aerobic mesophilic flora, yeasts, molds, and thermotolerant coliforms across the three production cycles. No pathogenic microorganisms like Salmonella, E. coli, or S. aureus were detected. The implementation of GMP, GHP, and Hazard Analysis and Critical Control Points (HACCP) principles enabled effective control of critical points, such as raw material reception, mixing, packaging, and storage. Conclusion: This study demonstrates that strict integration of hygiene and quality standards within small-scale food supplement manufacturing units significantly improves microbiological safety and consumer acceptability. It offers a reproducible model for other local food initiatives in sub-Saharan Africa in general and in Burkina Faso in particular.
