Resistant Starch Assay Kit (Rapid)

The Resistant Starch Assay Kit (Rapid) method is suitable for the analysis of resistant starch in pure starch, cereal and legume seeds and food samples.

This method is an update of the method of McCleary et al1 (AOAC Method 2002.02, AACC Method 32-40.01) employing incubation conditions similar to those used in AOAC Method 2017.16 for dietary fiber. The enzyme mixture employed [pancreatic α-amylase (PAA) and amyloglucosidase (AMG)] are those used by Englyst et al.2 except that both enzymes have been purified, standardised and stabilised. Digestion is performed using saturating levels of PAA and AMG with stirring at pH 6 and 37oC for 4 h, to simulate in vivo conditions in the human small intestine. Recent studies on the hydrolysis of “newer” resistant starch materials such as phosphate crosslinked starch (RS4) indicated that these incubation conditions are an essential requirement to obtain meaningful physiologically relevant values for RS.
