Abstract

''PROCESSO PARA PRODUZIR XILITOL DE ALTA PUREZA'' Apresenta-se neste um processo para produzir xilitol de alta pureza (processo de dessalgação de uma etapa) que compreende as etapas de (1) remover a matéria sólida de um caldo de cultura obtido pela cultura de um microorganismo de produção de xilitol em um meio aquoso de cultura, (2) dessalgar o caldo de cultura resultante da remoção da matéria sólida mediante a remoção das substâncias iónicas deste, por meio de uma resina de troca de cátion e uma resina de troca de ânion, (3) submeter a solução dessalgada resultante à cromatografia usando uma resina de troca de cátion fortemente ácida para separar o xilitol de outro(s) álcool(is) de açúcar e açúcar(es), e (4) obter o xilitol por separá-lo em uma alta pureza da solução de xilitol resultante (fração), e a um processo similar (processo de dessalgação de duas etapas), mas em que a dessalgação é realizada duas vezes mediante a adição da etapa de exclusão de íon entre as Etapas (1) e (2) do processo acima mencionado, por meio da qual a maioria das substancias iónicas são removidas, por cujos processos o xilitol altamente puro pode ser obtido a partir de uma solução de xilitol em uma maneira comercialmente eficaz, no processo de produção de xilitol mediante o uso de um microorganismo de produção de xilitol.
