Abstract :
The objective of the research was to evaluate changes of dietetic functional mixed cerrado fruit jam (marolo, sweet passion fruit, and soursop) processed in a vacuum pot and stored for 180 days in BODs at 25∘ C and 35∘ C. The parameters evaluated were pH, soluble solids (SS), titratable acidity (TA), total sugars (TS), total carotenoids (TC), total phenolics (TP), vitamin C, antioxidant activity
(DPPH), and microbiological analysis. There was a signifcant effect of storage time on pH, SS, TA, TC, TS, and TP. Vitamin C and
DPPH showed an effect for the temperature x storage time interaction. Statistical models are not adjusted for pH and SS, presenting
an average of 4.15 and 61%, respectively. Carotenoids decreased up to105 days; total sugars increased up to 105 days. The TP, vitamin C, and DPPH, at the temperatures evaluated, showed a decrease up to 105 days. Yeasts and flamentous fungi were not detected.
