The TSS is primarily represented by sugars, with acids and minerals
contributing. According to the Codex Alimentarius standard
(CODEXSTAN, 2009), normal fruit conserves or preserves must contain
P60% soluble solids. The TSS changes were not significant
(p < 0.05) by storage time, temperature or the interaction between
those factors. The TSS values found in this work at different storage
time and temperature, ranged between 64.42% and 67.30%, were
within values reported by Ferreira et al. (2004) for quince jams
which ranked between 59.2% and 75.1%.
