An in vitro system for the breakdown of starch granules by mixtures of a- and ß-amylase is developed and discussed with reference to information concerning the degradation of starch in vivo. ß-Amylase has no action on starch granules and has very little effect on the rate of starch granule digestion by a-amylase. It does, however, affect the product distribution in an a-amylase digest and is considered to attack dextrin intermediates produced by the action of a-amylase on the starch granules. © 1974.
