Leite de Castanha -do-Pará: caracterização físico-química e perfil de ácidos graxos

Abstract

The Brazil nut ( Bertholletia excelsa) is the fruit of the Brazil nut tree, a species native to the Amazon, in addition to the consumption of the almonds in their natural state, it is possible to obtain derivative products such as the plant plant-based milk extract. This is obtained through aqueous extraction and is considered a good alternative for people who are intolerant to lactose, milk proteins and allergies and it also helps reduce cardiovascular diseases.In this sense, the present study had as its main objective to obtain and characterize Brazil nut milk. The milk was evaluated for its physicochemical properties and determination of the fatty acid profile of the lipid fraction and nutritional quality index including lipids,moisture, ash,acidity,lipid profile by gas chromatography coupled to GC-MS mass spectrometry, atherogenicity (AI), thrombogenicity (AT) and hypocholesterolemic/hypercholesterolemic (H/H). The Brazil nut milk presents values of moistures (48,50%), lipids (42,15%). ash (1,22%) and acidity (2,10%). The lipid profile showed major values of unsaturated fatty acids such as oleic and linoleic respectively, white the nutritional quality index showed IA (0,30),IT (1,23) and H/H (3,31). Therefore, it is concluded that Brazil nut milk can be considered a food with high nutritional value and with vast benefits to cardiovascular health, as it presents in its lipid fraction a high content of unsaturated fatty acids, which corroborates its antithrombogenic, antiatherogenic and hypocholesterolemic action.
