RESUMEMalgré son importance nutritionnelle et socio-économique, la conservation du lait frais de vache demeure toujours un problème crucial dans les grands systèmes post-collecte du lait. La présente étude vise donc à évaluer les propriétés 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 Bénin. La détermination de la composition chimique des huiles essentielles par Chromatographie en Phase Gazeuse couplée à la Spectrométrie de Masse (CPG/CPG-SM) a indiqué que l'huile essentielle de Cymbopogon citratus a pour composés majoritaires le géranial (41,3%), le néral (33%) et le myrcène (10,4%), et celle de Mentha piperita, est majoritairement composée de menthol (46,7%) et de néomenthol (8,28%), avec une teneur en monoterpènes hydrogénés de 5,1%, en monoterpènes oxygénés de 87,0% et en sesquiterpènes hydrogénés 2,1%. Les résultats obtenus lors des essais de conservation du lait par adjonction des huiles essentielles ont montré que les huiles essentielles de Mentha piperita possèdent une forte activité antimicrobienne sur la flore d'altération du lait frais, comparativement à l'huile essentielle de Cymbopogon citratus.

“…In brief, bacterial strains were cultured in BHI at 37°C until an OD at 600 nm of 0.5. One hundred microliters of bacterial culture containing approximately 10 4 -10 5 CFU/ mL were spread on Mueller Hinton agar (MHA; Difco, of chemical preservatives, and has fuelled research into alternative natural antimicrobials (Lanciotti et al, 2004). Additionally, increased public awareness of the negative effects caused by synthetic chemicals has led to the search for "green solutions," such as organic and synthetic chemical-free food products (Abutbul, 2004).…”

In an effort to discover alternative antimicrobials against Listeria monocytogenes, several marine algae were screened. The methanolic extract of Ecklonia cava exhibited the highest antibacterial activity against L. monocytogenes, with the ethyl acetate (EtOAc) soluble fraction of E. cava methanolic extract having a MIC value of 256 µg/mL and a MBC value of 512 µg/mL. The MIC values of streptomycin in combination with the EtOAc fraction were markedly reduced up to 64-fold, suggesting that the antibacterial activity of the antibiotic was restored when combined with the EtOAc fraction. The interaction between streptomycin and the EtOAc fraction was assessed by fractional inhibitory concentration (FIC) indices. The combination of streptomycin and the EtOAc fraction against L. monocytogenes resulted in ∑FIC min range of 0.141 to 0.266 and ∑FIC max of 0.531 for all strains. The median ∑FIC against L. monocytogenes strains ranged from 0.172 to 0.344. Thus, synergistic ranges of FIC <1 were observed for all combinations of streptomycin and the EtOAc fraction against L. monocytogenes strains. Indeed, the median ∑FIC of streptomycin-EtOAc fraction ranged from 0.172 to 0.344, suggesting a marked synergy.

“…From practical standpoint, these components have found numerous applications in cosmetic and food industries since they were used to improve the shelf-life and safety of processed fruits 22 . In summary, results of this study indicate that leaves, flowers and fruits of Rosa x alba are rich sources of essential minerals mainly Ca, K, P, Mg, Fe, Cu, Mn and Na.…”

Rosa x alba is cultivated almost exclusively for the production of aromatic water and fruits widely used as ingredients in some traditional food preparations sold commercially. Results of the proximate and elemental analyses revealed that flowers exhibited higher moisture content while the dry matter content was higher in leaves. Total fat and ash was higher in fruits when compared with leaves and flowers. All studied organs were found to be rich in essential mineral such as K, Ca, P and Mg. Qualitative and quantitative analysis of the volatile oils revealed different composition patterns between organs. Linalool and geraniol were found as major constituents of the leaf oil whereas 2-phenethyl alcohol and eugenol were the major constituents of the floral oil. In contrast, fruits showed very distinct composition and alkanes/alkenes were found to have the major contribution. The present composition could justify the traditional use of Rosa x alba which could be considered as a potential source of essential minerals and volatile constituents.
