International Starch: Sorbitol and other polyols

Sorbitol and other polyols. Sorbitol is a sugar alcohol, C 6 H 14 O 6 found in nature as the sweet constituent of many berries and fruits best known from Sorbus aucuparia (Rowan or European Rowan) from which it was isolated for the first time in 1872. Mid 1950s, sorbitol large scale manufacture began due to new applications, such as humectant in cosmetology and sugar substitute in non .
