| Summary: | As a climacteric fruit, banana undergoes rapid ripening induced by the hormone ethylene, which is produced by
autocatalytic reactions. Titanium dioxide is a photocatalytic compound with the ability to degrade ethylene to water
and carbon dioxide. This compound can be used to control the concentration of ethylene inside storage chambers to
delay the ripening process of bananas in storage. A passive modified atmosphere is another method to delay ripening
by using storage spaces with limited air flow. This study attempts to investigate the performance of TiO2
-Mn and
bamboo fruit storage chamber (FSC) to delay the ripening of bananas by measuring characteristic physiological changes
for 7 days which included ethylene accumulation in storage space, rate of ethylene production, rate of respiration,
starch content, and soluble sugar content. The results show that the use of FSC in combination with TiO2
-Mn can be
used to delay the ripening of bananas. This study also investigated the effect of volumetric occupation to the efficacy
of FSC by varying the number of banana fingers in storage and varying the volume of the chamber. While the volume
of the FSC did not produce a significant difference in performance, the number of bananas stored in each FSC greatly
influenced the delay-ripening ability of FSC with TiO2
-Mn. At the end of the study, a profile plotted with MATLAB is
presented to show the relationship of ethylene concentration in FSC in respect to storage time and number of fingers
stored. |
