Sugars of lower molecular weights (glucose and fructose) were less effective in the reduction ofretrogradation than those of higher molecular weights (sucrose or trehalose). Trehalose retardedthe retrogradation of both corn and tapioca starch under all conditions investigated. Sucrose had same effect on corn starch retrogradation. The effects of other sugars depended on the type of starch, storage period, and storage temperature.
