Answer to Question 2

Tapioca is a root starch with the majority of its starch being amylopectin. With only a small amount of amylose, tapioca starch does not gel. It does undergo gelatinization. The water therefore, is bound to the starch and cannot be expressed. Tapioca would be used as a good thickener in all products, but especially in those that have to be frozen and thawed.
