In this study the stability of the Cereus jamacaru pulp fruit powder formulated with 10% maltodextrin, with equivalent dextrose (DE) of 10 and 14, packed in laminated packages during 50 days of storage under controlled conditions (25 °C and relative humidity of 57.7%) was evaluated. During storage at interval of 10 days analysis of moisture content, water activity, titratable acidity, ascorbic acid, color and wettability were performed. It was found that the laminated packaging failed to prevent the absorption of water with darkening of product. The water activity of the samples is considered microbiologically safe, because reached the maximum value of 0.351. The wettability of the fruit powder was higher using maltodextrin with DE 14 with reduction in the ascorbic acid content. The dextroses within their specificities showed similar behavior in powder samples.
