Resumo

The present study aimed at characterizing the oil extracted from Bertholletia excelsa H.B.K. almond, a native species from the Amazon region. Analytical methods used for oils and fats were employed through pharmacopoeia assays, AOCS (American Oil Chemists Society) standard methods as well as those recommended by ANVISA (National Health Surveillance Agency) such as acidity, peroxide value, saponification index, iodine value and refractive index, pH and relative density, and also thermoanalytical analyses (thermogravimetry, differential thermogravimetry and differential thermal analysis) as well as chromatographic analysis (gas chromatography). The characterization assessments of B. excelsa oil showed results indicating that the oil contains polyunsaturated fatty acids in large proportion. The termoanalytical tests indicated that B.excelsa oil showed thermal stability up to 220 °C, These results showed that the oil extracted from B. excelsa has acceptable characteristics and is of good quality.
