Durian (Durio
zibethinus Murr.)
is a famous fruit and it is known as the king of fruits. Durian is an economic
fruit of Thailand and is exported overseas, particularly, to most Asian
countries. However, durian has
very strong odor that is rejected by western consumers. Pandan (Pandanus odorus Rodl.)
leaf was experimentally used to reduce the durian odor by storing durian pulp
with pandan leaf. The results
indicated that pandan leaf stored with durian pulp at 1:5 by weight (pandan
leaf:durian pulp) had significantly less durian odor than control. Gas collected from the durian stored in
a polyester plastic bag had 3 volatile components: methane (58.99%),
ethanethiol (13.10%) and acetic acid methyl ester (28.91%). Whereas, storing the durian pulp with
the pandan leaf at 15˚C,
85+2% RH for 14 days had 10 volatile compounds: methane, acetaldehyde,
ethanethiol, acetic acid methyl ester, acetic acid ethyl ester, propionic
methyl ester, ethyl alcohol, propionic acid ethyl ester, 1-propyl acetate and ethyl
2-methylpropanoate (methane and ethanethiol
decreased). It may be concluded
that pandan leaf reduced durian odor by altering amount of some volatile
compounds on the odor.
