Classification: CPC A  C | IPC A  C

Claim 0:
1. An inhibited waxy tapioca starch having
an amylopectin content in the range of 90-100%; and
a sedimentation volume in the range of 18-35 mL/g;
wherein
the amylopectin fraction of the inhibited waxy tapioca starch has no more than 54.5% medium-length branches having a chain length from 13-24 as measured by the drop-to-baseline method, and/or
the amylopectin fraction of the inhibited waxy tapioca has at least 30.5% short-length branches having a chain length from 6-12 as measured by the drop-to-baseline method; and/or
the ratio (DP13-24−DP6-12)/(DP13-24+DP6-12) is no more than 28.0%, in which DP13-24 is the amount in the amylopectin fraction of the inhibited waxy tapioca starch of medium-length branches having a chain length from 13-24 as measured by the drop-to-baseline method, and DP6-12 is the amount in the amylopectin fraction of the inhibited waxy tapioca starch of short-length branches having a chain length from 6-12 as measured by the drop-to-baseline method; and

wherein the inhibited waxy tapioca starch is prepared by adjusting an aqueous slurry of a tapioca starch feedstock to a pH in the range of 3.5-7.0 followed by drying and heating the pH-adjusted starch and is not pregelatinized.
