Abstract

Se convierte directamente almidón granular en un producto hidrolizado de almidón soluble, caracterizado porque a) se agita la mezcla de almidón, agua y preparado de enzima alfaamilasa a un temperatura dentro del margen de desde la temperatura de gelatinización inicial normal del almidón hasta la temperatura de gelatinización inicial normal del almidón hasta la temperatura de gelatinización real del almidón, b) se ajusta la temperatura a un valor dentro del margen de desde aproximadamente 50ºC hasta aproximadamente 65ºC y el pH a un valor dentro del margen de desde aproximadamente 4 hasta aproximadamente 6 y se añade el preparado de enzima sacarificador, y c) se recupera desde dicha mezcla el producto hidrolizado de almidón no soluble residual retiene sustancialmente su forma granular no gelatinizada.
