The objective of this research was to compare the physical-chemical, spectroscopic and fatty acid profiles of Brazil nut oils from the 2018 and 2019 harvests. The methodological procedures followed the internationally accepted standards of the American Oil Chemist’s Society. The analysis of the physical-chemical properties showed oils with high quality for human consumption, within the quality standards defined by Brazilian legislation. In relation to the different harvests, during the analyzed period, they did not present differences maintaining their high quality as a function of time. The spectral bands show chemical groups characteristic of long-chain fatty acids, without the presence of compounds related to oxidative processes. The fatty acid profiles showed high quality in constituents related to the fatty acids components of the omega family (ω-3, ω-6 and ω-9) showing the maintenance of the functionality of the products extracted from this oilseed, without changes in the chemical constituents in the analyzed crops.
