  • Method of preventing cut pieces of agricultural products containing starch from sticking to each other in the drying and cooking steps
    Patent number: 5312631
    Abstract: A method for preventing cut pieces of agricultural products containing starch, particularly potatoes, from sticking to each other during the steps of drying and cooking, which includes washing the cut pieces with, or immersing the same in, a solution of an amylolytic enzyme, or an acidic or alkaline aqueous solution, or performing the washing or immersing treatment after blanching the cut pieces, thus saccharifying the starch existing on the surface of the cut pieces and removing the sugar thus formed from the cut pieces and thereby preventing the sticking of the cut pieces in the subsequent heating and drying steps.
