Secagem de extratos de erva-mate em secador por atomiza??o

摘要

It was effected extraction of soluble of mate, lineage Cambona 4, using extracting, with percolating of solvent (water). The gotten extract presented a 3% solid concentration. The extract was used for formularization of mixtures with arabica gum in the concentrations of 0; 0.2; 0.4; 0.6; 0.8; 1.0; 1.5 and 2.0%, in relation to solids contained in the extract. The formularizations had been effected with the objective to study the volatile and aromatics substance clamping. The extracts had been processed in spray dryer in the average operational conditions: temperature and tax of air: 190oC and 32.1m3/h; extract feed of 340mL/h. The contents of humidity of the gotten dust had varied of 1.8 to 6.6%(db). Sensorial analysis of three formularizations with concentrations was carried out: 0; 0.2 and 1.0%. A statistical analysis were carried out to experimental results and was verified bigger preference for the formularization contends 0,2% of gum arabic, what it showed the influence of the encapsulating agent in the clamping of flavor.
