Frozen camu–camu pulp was acquired at the Central Supply Market of Rio de Janeiro state. The pulp was thawed according to the amount necessary for each process. The camu–camu pulp was initially centrifuged, aiming to standardize and reduce the sus- pended solid content, with the aid of a basket centrifuge SIZE 2 (International Equipment Company, Needham, USA), at 4000 rpm (479.2 g), using a 150 lm NylonÒ screen as the filter media. The centrifuged juice was then clarified in a semi-pilot system of crossflow microfiltration (TIA, Techniques Industrielles Appliquées, Bollene, France) consisting of four tubular ceramic membranes of a-alumina, T1-70 (Pall Corporation: MembraloxÒ Ceramic Mem- brane Products, New York, USA), with mean pore size diameter of 0.1 lm and total permeation area of 0.022 m2. Microfiltration was performed at 45°C, with a transmembrane pressure of 2.5 bar and tangential velocity of 6.9 m/s.
