A maltotriose-generating amylase has an amino acid sequence of any one three polypeptides. One or more amino acids can be substituted, added, inserted, or deleted, such that the polypeptides have at least 70% sequence identity with the amino acid sequences of the polypeptides. The polypeptides are encoded by DNA, which can be included in recombinant vectors. Transformants can be obtained by transforming a host with the DNA.

The present disclosure relates to waxy maize starches having desirably high process stability, and to methods relating to them, including methods for making and using them. One aspect of the disclosure is a waxy maize starch having an amyiopectin content in the range of 90-100%; wherein the amyiopectin fraction of the waxy maize starch has at least 28.0% DP3-12 branches: and no more than 53.0% DP 13-24 branches, no more than 16.0% DP 25-36 branches. Such waxy maize starches can be advantaged over conventional waxy maize starches in that they can have increased process stability, especially with respect to freeze-thaw stability. Methods of making the starch materials, using exo-hydrolyzing enzymes and methods of using the starch materials in food products are also described.
