Sucrose, fructose and total sugar (TS) exhibited significant reduction (Pb0.05) only at 37 °C. Free
amino acids (FAAs), L-ascorbic acid and solubility of tomato powder underwent significant reduction and
total color change ΔE significantly increased after 5 months regardless of storage temperatures (Pb0.05),
while lycopene and total soluble solid (TSS) showed no significant changes (PN0.05). SEM micrographs
indicated that tomato powder tended to aggregate with increasing the storage temperature or time, which
conformed to decreased Tg. There were good correlations between HMF and total free amino acids (TFAA),
