Extensive hydrolysis of clusters with α-amylase releases small,tightly branched areas in clusters, which are known as building blocks. Linear dextrins with DP 1–6 are released from segmentslocated between the branched blocks. These linear dextrins arefurther hydrolyzed into glucose, maltose, and maltotriose by treatment with β -amylase, a procedure that results in a better sizeseparation of the linear products from the branched building blocks
