In April 2001, the National Academy of Sciences (NAS) released its proposed definition, stating that total fiber in a product is the sum of dietary fiber and added fiber (isolated, non-digestible carbohydrates which have beneficial physiological effects in humans). These definitions—and a new, approved Association of Official Analytical Chemists (AOAC) method for the determination of polydextrose (2000.11)—will allow product developers to include polydextrose in the total fiber content of a product.
Danisco Sweeteners, Ardsley, N.Y., offers a full line of polydextrose products that are 1 kcal/g specialty carbohydrates made from glucose, sorbitol and citric acid, under the trade name Litesse®. Traditionally used as both a sugar and a partial fat replacer, formulators may now use it as a source of soluble fiber. With a 90% dietary fiber content, it can supplement fiber content in foods and beverages. Several clinical studies indicate the beneficial physiological effects of Litesse.
