Effect of GRAS compounds on mycelial growth, pectic enzyme activity and disease severity of postharvest pathogens on rambutan (Nephelium lappaceum).

The GRAS (generally recognized as safe) compounds cinnamaldehyde (30 ppm), acetaldehyde (70 ppm), benzaldehyde (50 ppm) and potassium metasulfite (250 ppm) either completely inhibited or significantly reduced the in vitro mycelial growth of Gliocephalotrichum microchlamydosporum, Colletotrichum gloeosporioides [Glomerella cingulata] and Botryodiplodia theobromae, the causative fungi of brown spot, anthracnose and stem end rot, respectively, of rambutan Nephelium lappaceum fruits. The four compounds also significantly reduced the severity of all three diseases and the activity of pectic lyase and polygalacturonase enzymes secreted by the three fungi.
