DAMIANI, Clarissa et al. Antioxidant potential of Psidium guinnensis Sw. jam during storage. Pesqui. Agropecu. Trop. [online]. 2012, vol.42, n.1, pp. 90-98. ISSN 1983-4063. http://dx.doi.org/10.1590/S1983-40632012000100013.
The araçá (Brazilian guava) jam is a promising alternative for expanding the consumption of this fruit, besides adding value to it and making the Brazilian Savannah fruits known. Therefore, this research aimed to study the physical and chemical characteristics of the araçá jam, as well as to evaluate the presence and behavior of antioxidant compounds and color, during 12 months of storage. The results obtained for centesimal composition, sugars, fibers, pectin, and consistency showed that the use of araçá was suitable for the jam production, and that the product remained within the standards established by the Brazilian legislation. The total acidity, phenolic compounds, color parameters, and organic acids contents decreased during storage, while the pH and antioxidant potential increased, during one year of storage. Thus, it was possible to conclude that the araçá jam is a product with good nutritional characteristics, presenting good levels of antioxidant compounds, during storage, and meeting the demands of the modern consumer, i.e. practicality and healthiness.
