The investigation highlighted the antifungal effectiveness in culture medium and traditional cheese
wagashi foodsystem of Syzygium aromaticum (Eugenia caryophyllata) essential oil (EO) against
spoilage and toxinogenic moulds isolated from wagashi produced in Benin. The chemical composition
of the EO obtained by hydrodistillation, characterized through GC-FID and GC-MS analysis, revealed
eugenol (75.2%) and trans-caryophyllene (12.0%) as major components. The evaluation of in vitro
antifungal activity of this oil showed a significant fungistatic activity against Aspergillus (flavus,
tamarii, niger, aculeatus, ustus, terreus), Penicillium (brevicompactum, citrinum, griseofulvum),
Fusarium (poae, verticillioides) and Scopulariopsis brevicaulis with MIC ranged from 200 to 600 mg/L
due probably to its richness in eugenol. Moreover, this EO had fungicidal activity against Aspergillus
terreus and S. brevicaulis which were the most sensitive respectively at 600 and 400 mg/L. The
assessment of antifungal activity of the oil studied in wagashi foodsystem against the less sensible
isolates at in vitro assay revealed high sporale reduction rate (55% at least at 1000 mg/L) on all species
investigated above all on Penicillium citrinum and Aspergillus aculeatus, two harmful mycotoxins
producers in cheese. Results obtained indicate the possibility of exploiting S. aromaticum EO to
preserve wagashi against moulds contamination and probably mycotoxins inhibition during wagashi
storage. |
