Description
A sweet-tasting, crystalline powder. Mannitol occurs naturally in plants and seaweeds. Mannitol will liquefy any gum solution that has been gelled with borate because it reacts with borates to form mannitoborate. Examples of gums that gel with borate are Gum arabic, Locust bean gum, and gum guar. Mannitol has been used in conjunction with Sucrose for the impregnation of waterlogged wood (Morgos and Imazu, 1993).
