Abstract
Durian fruit has a strong flavor.
Its odor emits into surrounding atmosphere even when the husk is intact or when stored in film packaging.
A TiO2-coated film was studied as an active packaging for decomposition of durian flavor volatiles in package atmosphere.
Research showed TiO2-coated film worked during UVA light illumination and that it was effective in decomposition of durian flavor volatiles.
After 1 h of light illumination, the durian volatile compounds in a package atmosphere was extracted by solid-phase microextraction (SPME) with PDMS/DVB fiber coating for 30 min. and analyzed by GC-MS. The results showed that TiO2-coated film decreased the concentration of headspace total volatile compounds of durian compared to uncoated film.
Sulfur compounds such as ethanethiol and s-ethyl ethanethioate, including major ester compounds of durian flavor were decomposed by the photocatalytic reaction of TiO2-coated film.
Sniffing of durian flavor in headspace packaging by panelists revealed that durian flavor was undetectable in TiO2-coated film after 1 h of UVA light illumination, while strong odors were detected in headspace packaging of uncoated film treatment regardless of light illumination.
