Resumen
Marolo, also known as araticum or head-to-black, is a globular berry, a species native to the Brazilian savannah. The aim of
this study was to evaluate the physical, chemical, and microbiological stability of frozen marolo pulp during 12 months of
frozen storage. It was observed that the levels of ash (0.28-0.22%), protein (0.77-0.71%), lipids (1.75-1.73%), carbohydrates
(12.1-10.15%), calorie (67.23-59.01 kcal), sucrose (2.50-1.29%), citric acid (435.63-197.5 μg.g –1 ), tartaric acid (4.38-1.88 μg.g –1 ) ,
acetic acid (470.38-279.25 μg.g –1 ), ascorbic acid (3.00-0.00 μg.g –1 ), total pectin (0.67-0.39%), pH (3.88-3.83), and b* chromaticity
coordinates (24.85-20.53) decreased reduced during storage, whereas the levels of moisture (85.10-87.19%), color parameters
(L* 58.89-62.62 and a* 5.37-7.86), reducing sugars (4.53-5.62%), total soluble sugars (7.1-7.36%), soluble solids (7.0-8.4 °Brix),
total acidity (0.9-1.0%), malic acid (514.13-781.25 μg.g –1 ), soluble pectin (0.16-0.24%), and antioxidant (6.85-37.35% of DPPH
discoloration) increased over the one-year of storage period. According to the physical, chemical, and microbiological parameters
assessed, the product can be stored for 12 months without loss of quality with addition of citric acid as a preservative.
