Aplicaçao do metodo de Pfeiffer a sementes de café (Coffea arabica L.)
The object of this work is to study the crystallization patterns of copper chlorids (CuCl2.2H2O) as influenced by extract of coffee seeds (Coffea arabica L.), variety Mundo Novo. Investigation and description are made for 16 different concentrations of the water-copper chloride-extract system, with 3 replications. The best crystallization patterns were obtained by using the filtered-misture technique. The results indicate that concentrations between 0,5 and 1,0 g per plate of crystallization patterns were obtained by using the filtered-misture technique. The results indicate that concentrations between 0,05 and 0,075 g per plate of extract can be recommended
