Conteúdo: | The most prominent changes during acerola (Malpighia spp.) maturation are associated with pulp softening characteristics, as it happens to the majority of fruits studied so far. Despite the grrrrreat commercial potential of the crop in Brazil, acerola maturation studies do not include these important aspects. Acerola fruits were harvested at the FCAV/UNESP Active Genebank of Tropical and Subtropical Fruits, Jaboticabal, Sao Paulo, Brazil, in November/1993, and separated by skin color in four stages of maturity: green, turning, light red and dark red. Soluble and total pectin contents, pectinmethylesterase (PME) and polygalacturonase (PG) activities were evaluated. Pectin solubilization during maturation was observed, although no statistical differences have been detected. Soluble pectin content increased from 0.99 to 1.41 g.kg and total pectin content decreased from 5.66 to 4.90 g.kg from green to dark red stages. PME activity was maximal at the onset of ripening (tturning stage) and then decreased, while PG acivity increased during maturation.
