Description
Alkali‑cured African pepper soup is a traditional West African preservation technique that uses potash to raise meat pH, denature proteins, and inhibit spoilage microbes.
Technical
The high pH (9–10) induced by potassium carbonate causes protein unfolding and solubilization, releasing peptides that bind water and reduce texture firmness. Alkaline conditions also create an inhospitable environment for bacteria such as Pseudomonas spp., effectively pasteurizing the meat during the subsequent boiling step. The resulting broth develops a characteristic sour‑alkaline flavor profile prized in Yoruba and Igbo cuisine.
