Abstract

Butiá is a native fruit from the Butiá Palms in the east of Uruguay, whose consumption and commercialization is limited to this region. The analysis of physicochemical and nutritional properties in the fruit and its screened pulp will encourage the enhancement of this native genetic resource. The aim of this study was to expand knowledge about the physical, chemical and nutritional characteristics of the fresh fruit and its screened pulp. We also studied the microbiological evolution of the sived pulp stored at -18 °C for 360 days. In order to characterize the fruit, measurements of total soluble solids, pH, reducing sugars, titrable acidity, dry matter, pectin, total dietary fiber and vitamin C were carried out. Most relevant results obtained from the fruit were 65 to 100 ppm of vitamin C and 4,3 to 4,9 % of total dietary fiber. In the screened pulp, total soluble solids, pH, color, vitamin C, pectin, aerobic mesophilic microorganisms, fungi and yeast were analyzed. The high content of vitamin C in the fruit was preserved up to 55 % in the screened pulp. During the 360 days of storage at -18 ºC no microbiological growth in screened pulp were found
