Maltitol Maltitol is a sugar alcohol created by hydrogenating maltose from starch hydrolysates, providing nearly identical bulk, sweetness, and functionality to sucrose but with only 2.1 kcal/g and low glycemic impact. It excels in sugar-free products by mimicking sugar's role in crystallization, texture formation, and processing tolerance across baking, extrusion, and high-heat applications without causing digestive discomfort at typical usage levels.
