Resumo
The objective of this study was to add value to araça and marolo fruits by developing jams and verifying changes in their physical, chemical,
and microbiological parameters during storage. The analyses were carried out every 2 months. From the results, it was shown that the levels
of moisture (35.89 – 26.34%), lipids (0.43 – 0.27%), sucrose (30.62 – 28.98%), total pectin (0.83 – 0.50%), soluble pectin (0.52 – 0.38%), total
phenolic compounds (180.31 – 135.52 mg.GAE 100 g–1), and organic acids (401.1 – 68.5 μg.g–1 citric acid) decreased during storage. However,
the levels of protein (0.83 – 0.95%), carbohydrate (62.52 – 72.5%, calories (257,11 – 295,931 kcal), fiber (0.72 – 1.4%), total soluble sugar
(62.52 – 70.44%), reducing sugar (32.05 – 41.41%), soluble solids (68.4 – 72.18 °Brix), consistency (0.33 – 0.44 N), total antioxidant potential
(11.3 – 22.63%), and color (a* 7.56 – 9.49, and b* 8.63 – 10.49) increased during 1-year storage. The quality of the fruit jams studied was in
accordance with the microbiological standards established by the Brazilian legislation. It was concluded that the mixed araça and marolo
jam can be stored for 1 year without the addition of additives.
