Reflects of clarification of sugarcane juice with moringa on inorganic compounds of sugar VHP

The aim of this study was to determine the effects of sugarcane juice clarification, using extract of leaves and seeds of moringa (Moringa oleifera Lamarck) as auxiliary sedimentation, on the concentration of inorganic compounds of clarified juice and sugar VHP (Very High Purity - Export Type). The experimental design used was a 5 x 2 factorial arrangement with four replications. The performed main treatments included the extracted original sugarcane juice, the synthetic polyelectrolyte, the leaf and seed extract, and a control. The secondary treatments consisted of the sugarcane varieties RB92579 and RB867515. The sugarcane juice was clarified by simple defecation, evaporated until 60 oBrix and subjected to a cooking process. In the original juice, in the clarified juice and in the produced sugar the phosphorus, potassium, calcium, sodium, magnesium, manganese, iron and total ashes contents were quantified. The use of extract of leaves and seeds of moringa was effective on juice treatment destined to sugar production, as they removed high quantities of calcium and iron compared to the synthetic polymer. The extract of leaves was the better auxiliary in sedimentation when compared to the others.
