Type 1 RS
The literature describes size-reduction treatments to decrease type 1 RS, but contains little about how to increase type 1 RS by processing treatments. The enzyme resistance of type 1 RS is based on the inaccessibility of the enzyme to the starch, and it does not depend on the intrinsic enzyme resistance of the starch itself. In theory, any source of starch could be trapped in a food in such a way to make it inaccessible to enzymes. If this type of RS were part of an ingredient to be used in a manufactured food, the ultimate RS level in the food would depend on the stability of the entrapping material to the conditions during manufacturing.
