The postharvest team has
established more than a decade of collective
expertise in the area of postharvest
physiology and biochemistry in a number of
local fruits. The team established itself
with the Banana Project which started in the
late 80’s under the supervision of Professor
Helen Nair with the primary aim of
understanding postharvest physiology in view
of extending shelf life that may boost the
possible export value of Mas (AA) bananas. A
vacuum-pack technology was successfully
developed by the postharvest team for the
long term storage of Mas bananas in the
early 90’s (Nair and Tung, 1991) and later
extended to several other dessert and
cooking bananas (Balamohan et al.,
1997). The group has also looked at the
physiological and biochemical changes during
ripening and extended storage of bananas (Chandran,
1998).Since then, the team has expanded
postharvest research to other horticulture
produce including mangoes, papaya,
dragonfruits, hibiscus and orchids.
Research group focus
areas include post-harvest
physiological, biochemical and molecular
studies, and the technological
approaches for improving quality and
extending longevity of fruits and
flowers.
The expertise of the
research group also extends to
diagnosing post-harvest diseases and
disorders in fruits and flowers.
Research Project in Progress
Construction of genomic
DNA library from BB wild
Bananas
for the improvement of commercial
bananas
Extraction and
characterization of natural red pigment
from dragon fruit (Hylocereus
polyrhizus) as natural food dye and
a potential source of antioxidant.
Molecular approaches for
characterization and conservation of
genetic resources in mangoes.
Lab activities
Currently working on
collaboration with the industry to
establish effects of hot water treatment
on the quality of papaya, application of
modified atmosphere packaging to extend
the shelf life and development of
natural red dye from dragon fruit.
Construction of a genomic
library for mangoes, phylogenetic
classification of Malaysian bamboos,
molecular expression studies on
senescence-related genes in orchids and
cell wall hydrolases studies in bananas.
Biotechnology for Banana
improvement and Biotechnological
manipulation of Orchids
To look at current
problems of postharvest handling and
storage and offer improvements by
providing input
To study at a molecular level the
application of biotechnology for
improving postharvest quality of produce
eg: development
of disease resistance clone, engineering
of fruits or flowers with longer shelf
life.
