Influence of <i>Pediococcus pentosaceus</i> Starter Cultures on Biogenic Amine Content and Antioxidant Activity in African Sourdough Flatbread Fermentation.

ABSTRACT: This study investigated the impact of Pediococcus pentosaceus strains not only on biogenic amine (BA) content, but also on antioxidant indices, including 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity and total phenolic content, in kisra, an African sourdough flatbread. Among forty-six lactic acid bacteria (LAB) strains isolated from naturally fermented kisra sourdough, two strains (K-B21, K-B01) identified as P. pentosaceus, were selected due to their low BA-producing and high BA-degrading ability for kisra fermentation. Inoculation with P. pentosaceus K-B21 or P. pentosaceus K-B01 completely prevented the formation of tyramine and cadaverine during kisra fermentation. The levels of putrescine, histamine, spermine, and spermidine in kisra were reduced
