Maltitol is made from corn starch or wheat starch that has been converted into maltose (a type of sugar). This process requires enzymes to break down the starch into glucose (which is then further processed into maltose). This process also requires heat to separate the enzymes from the final product.

The final product is then treated with lactase (an enzyme found in milk) to convert any remaining glucose into lactic acid. The result is a substance called maltitol syrup, which can be dried and turned into maltitol crystals when exposed to air pressure or vacuum drying processes.
