Abstract

<B>ARGILA DE BRANQUEAMENTO E MéTODO DE FABRICAçãO<D> é produzida uma argila de branqueamento melhorada com ácido útil na remoção de impurezas coloridas de óleos comestíveis, por meio de um processo não-pastoso, que não agride o meio-ambiente, que inclui moagem, acidificação e secagem da argila a um teor de umidade livre não superior a cerca de 13% em peso. O teor de ácido do produto de argila está na faixa de cerca de 1 a cerca de 5% em peso, preferivelmente cerca de 2,5 a cerca de 5% em peso, com base no peso seco da argila.<B> BLEACHING CLAY AND MANUFACTURING METHOD <D> an acid-enhanced bleaching clay is used to remove colored impurities from edible oils, using a non-sticky process that does not harm the environment, which includes grinding, acidifying and drying the clay to a free moisture content of no more than about 13% by weight. The acid content of the clay product is in the range of about 1 to about 5% by weight, preferably about 2.5 to about 5% by weight, based on the dry weight of the clay.
