Malgre son importance nutritionnelle et socio-economique, la conservation du lait frais de vache demeure toujours un probleme crucial dans les grands systemes post-collecte du lait. La presente etude vise donc a evaluer les proprietes antimicrobiennes des huiles essentielles extraites des feuilles de Cymbopogon citratus et de Mentha piperita dans la conservation du lait frais de vache au Sud du Benin. La determination de la composition chimique des huiles essentielles par Chromatographie en Phase Gazeuse couplee a la Spectrometrie de Masse (CPG/CPG-SM) a indique que l’huile essentielle de Cymbopogon citratus a pour composes majoritaires le geranial (41,3%), le neral (33%) et le myrcene (10,4%), et celle de Mentha piperita, est majoritairement composee de menthol (46,7%) et de neomenthol (8,28%), avec une teneur en monoterpenes hydrogenes de 5,1%, en monoterpenes oxygenes de 87,0% et en sesquiterpenes hydrogenes 2,1%. Les resultats obtenus lors des essais de conservation du lait par adjonction des huiles essentielles ont montre que les huiles essentielles de Mentha piperita possedent une forte activite antimicrobienne sur la flore d’alteration du lait frais, comparativement a l’huile essentielle de Cymbopogon citratus.© 2016 International Formulae Group.

Thus, the present study aims to investigate the antimicrobial properties of essential oils extracted from leaves of Cymbopogon citratus and Mentha piperita in conservation of fresh cow's milk in southern Benin. The determination of the chemical composition of essential oils by gas chromatography coupled with mass spectrometry (GC / GC-MS) indicated that the essential oil of Cymbopogon citratus has geranial (41.3%), neral (33%) and myrcene (10.4%) as major compounds and Mentha piperita essential oil has menthol (46.7%) and neomenthol (8.28%) as major compounds with a hydrogenated monoterpenes content of 5.1%, oxygenated monoterpenes 87.0% and 2.1% for hydrogenated sesquiterpenes. The results obtained from fresh milk stored with essential oils have indicated that essential oil  of Mentha piperita has strong antimicrobial activity on spoilage flora of fresh milk, compared to the essential oil of Cymbopogon citratus.© 2016 International Formulae Group.
