ABSTRACT - This study aimed to extract the oil from macauba pulp using a low-pressure solvent extraction, as well as characterisation of the extracts and defatted meal obtained using different solvents (n-hexane, ethyl acetate and isopropanol). Results reported higher yields in oil, 27.43%, using isopropanol (P&lt;0.05), wherein the highest levels of β-carotene in the extract, 348.30mg 100g-1, were obtained with this solvent. In the composition of the extracts, monounsaturated fatty acids were predominantly found, and it was reported that the type of solvent had no significant influence (P&gt;0.05) on the composition; however, in the quantification of free glycerol compounds, isopropanol showed higher levels, 104.15mg 100g-1, of these compounds (P&lt;0.05). Meals had higher ash, protein and fibre content when compared to pulp. Thus, oil removal can be stated to promote water retention capacity; however, it has no influence on the other technological characteristics evaluated.

Key words: Acrocomia aculeata, vegetable oil, defatted meal.</abstract>

RESUMO - O presente trabalho objetivou a extração do óleo da polpa de macaúba utilizando extração por solvente a baixa pressão, bem como a caracterização dos extratos e farelos obtidos, utilizando diferentes solventes (n-hexano, acetato de etila e isopropanol). Os resultados reportam maiores rendimentos em óleo, 27,43%, na utilização do isopropanol (P&lt;0,05), sendo que os maiores teores em β-caroteno no extrato, 348,30mg 100g-1, foram obtidos com este solvente. Na composição dos extratos, predominam os ácidos graxos monoinsaturados e relata-se que o tipo de solvente não apresentou influência significativa (P&gt;0,05) na composição, no entanto, na quantificação dos compostos livres de glicerol, o isopropanol apresentou os maiores teores, 104,15mg 100g-1, desses compostos (P&lt;0,05). Os farelos apresentaram maiores teores de cinzas, proteína e fibras, quando comparados à polpa. A remoção do óleo favorece a capacidade de retenção de água, no entanto, não tem influência nas demais características tecnológicas avaliadas.
