Abstract


Crude, neutro and blenched oil extracted from pulp and peel of jungle fruit Paraqueiba sericea tulasne «Umarí» were studied. The crude oil was extracted with hexane by the soxhlet method giving a 47.86% yield, a 31.72% yield in neutro oil and a 94.89% yield in blenched oil. Chemical and physical constants were determined. In addition, five methyl esters of fatty acids were quantitatively determined by GLC using DEGS as stationary phase. The results indicated that Umarí oil belongs to a not drying type with a high content of unsaturated fatty acids principaly oleic. The analytical values obtained confirm the convenience of using Umarí oil in food and cosmetic industries.

Keywords
