Traditionally, fruits are harvested through conventional
methods which are based on smell, texture and harvesting
time. This analytical technique has many disadvantages in
terms of objectivity and subjectivity. Electronic nose (enose)
is an artificial olfaction device that is able to
replicate the human olfactory sense. By determining
various fruits volatile released during pre-matured until
matured period, one can actually selectively establish the
exact time of a fruit to ripe. In this research, innovative
electronic nose will consists of a multi-sensors array
based MIP (Molecularly Imprint Polymer) and tuned to
give a fingerprint of fruit aroma volatiles when a fruit is
ripe. The classification findings of this study provide
breakthrough for the agricultural sector since volatile
sensing of chemical markers would help to ensure to
maintain their quality and standards during fruit
harvesting time.
