Impact of different extraction methods on the quality of Dipteryx alata extracts

Abstract

This study aimed to impact of different extraction methods on the quality of Dipteryx alata Vogel, Fabaceae, extracts from fruits. The major compounds found were the lipids 38.9% (w/w) and proteins 26.20% (w/w). The residual moisture was 7.20% (w/w), total fi ber 14.50% (w/w), minerals 4.10% (w/w) and carbohydrate 9.10 % (w/w). The species studied has great potential in producing oil, but the content and type of fatty acids obtained is dependent on the method of extraction. The Blingh & Dyer method was more selective for unsaturated fatty acids and Shoxlet method was more selective for saturated fatty acids. The tannin extraction by ultrasound (33.70 % w/w) was 13.90% more effi cient than extraction by decoction (29 % w/w).
