The pasting of starch refers to the process of mixing starch and sufficient water, and under conditions such as heat or strong alkali, the starch forms a homogeneous pasty solution. The saccharification of starch refers to the degradation of starch into maltose, fructose, glucose and other oligosaccharides or monosaccharides. In industry, it is usually pasted first and then saccharified, and the pasted starch is easily degraded.
