Abstract

"PROCESSO PARA PREPARAçãO DE PARTìCULAS DE AMIDO EM UM SISTEMA DE DUAS FASES". A presente invenção se refere a um processo para preparação de partículas de amido em um sistema de duas fases, o processo compreendendo pelo menos as seguintes etapas: a) uma preparação de uma primeira fase compreendendo uma dispersão de amido em água; b) preparação de uma dispersão ou emulsão da primeira fase em uma segunda fase líquida, contanto que a segunda fase não seja água; c) reticulação do amido presente na primeira fase; d) separação das partículas de amido assim formadas. De acordo com o primeiro aspecto da invenção, a segunda fase consiste de um líquido hidrófobo e a etapa b) consiste na formação de uma emulsão de óleo-em-água, que é então invertida para uma emulsão de água-em-óleo. De acordo com um segundo aspecto da invenção, a segunda fase consiste de um não-solvente miscível em água para amido. Tais partículas de tamanho de partícula muito pequeno podem ser produzidas de maneira controlada por meio deste processo.
