Abstract: The effects of 21 volatile monomers from Hanseniaspora uvarum on spore germination and mycelial growth of the gray mold Botrytis cinerea were evaluated under in vitro conditions. This study also determined the efficacy of ethyl 3-hydroxybhexanoate, ethyl caprate, cinnamaldehyde and ethyl caprylate to control postharvest gray mold in strawberries. The results showed that all volatile monomers except lauric acid inhibited mycelial growth and spore germination of Botrytis cinerea, which was completely inhibited by cinnamaldehyde at 62.5 and 625 μL/L, respectively. All four volatile monomers tested suppressed the occurrence of gray mold, maintained the color, and inhibited the decrease of total soluble solids, titratable acid and hardness of postharvest strawberry. Among these, cinnamaldehyde had the potential to be used as a biocontrol agent against strawberry gray mold disease with good commercial prospects.
