Two samples of Tapioca starch of different viscosities have been crosslinked with sodium trimetaphosphate, epichlorohydrin, and phosphorus oxychloride. Of these crosslinking agents, epichlorohydrin is the most efficient, requiring only 0.01 to 0.15% of the reagent on the weight of starch. It is noted that tapioca starch having initially a high viscosity requires less amount of the crosslinking agent for stabilization of its paste viscosity as compared to the starch sample having low initial viscosity.
