Tóm tắt

This paper reports on the applicability of novel alkyl carbonate-based phase change material (PCM) in
the preservation of foodstuffs during transportation, which could subject the foodstuffs to extreme
thermal stress due to poor insulation and solar exposure. In particular, this study evaluated the
changes in several quantifiable properties of cherry tomatoes (Lycopersicon lycopersicum var.
cerasiforme) during short-term storage – including total soluble solids (TSS), titratable acidity (TA),
sugar-acid ratio, pH, total lycopene, and total carotenoids – after their exposure to normal truck's
cargo box conditions during transportation, with or without the novel PCM acting as additional
thermal insulation. Experimental results showed that the novel PCM did effectively reduced the impact
of temperature fluctuations on quality of cherry tomatoes, therefore showed great potential in
preservation of foodstuffs during transportation.
