    摘要: The invention relates to improved methods for extracting and purifying limit dextrinase enzymes from cells, in particular plant cells. The process of the invention includes heating a cell homogenate at 4O° C., in the presence of divalent cations thus increasing the specific activity of the limit dextrinase.
