Seham S. El-Hawary, Rabab Mohammed, MarwaEmad El-Din, Ghada Awad


Five strawberry (Fragaria x ananassa. Duch.) cultivars (Festival, Red Merlin, Suzana, Tamar and Winter Dawn) were analysed using solvent-solvent extraction method and GC/MS system to compare between the volatile constituents responsible for the aroma in different fresh and frozen cultivars. The main identified compounds were Tetradecene (15.41%), 2E-dodecene-1-ol (13.78%), Nerolidol (11.37%), E-14-hexadecenal (17.27%) and Octadecanol (17.65%). The present study explains the effect of freezing on aroma content for different strawberry cultivars. Nutritional value contents of the fruits were also estimated which illustrate the importance of fruits as a main source of vitamin C and potassium. The antimicrobial activity of the volatile constituents were estimated and were exhibited a significant results (20-32mm zone of inhibition) against number of human pathogenic microorganisms, compared with the standard antibiotic (20-22 mm zone of inhibition) using the agar well diffusion method.

Keywords:Fragaria x ananassa, antimicrobial, cultivars, volatile constituents.
