Abstract
An inhibited non-pregelatinized granular starch suitable for use as a food ingredient in substitution for a chemically modified starch may be prepared by heating a non-pregelatinized granular starch in an alcoholic medium in the presence of a base and/or a salt. Steam treatment may be used to enhance the extent of inhibition.
Claims14
An inhibited non-chemically modified non-pregelatinized granular starch that is highly inhibited, the inhibited non-chemically modified non-pregelatinized granular starch having:
- a continuing rise in viscosity without attaining a peak viscosity, wherein viscosity is measured by heating the starch in an amount of 5% to 6.3% dry solids basis in water having a pH of 3 at a temperature of 92° C. to 95° C., wherein the inhibited non-pregelatinized starch is not chemically modified;
- a specific sedimentation volume of no more than 18 mL/g, the specific sedimentation volume being the bulk volume occupied by swollen starch granules per mass unit of dry starch, when cooked using a Rapid Visco Analyzer under the following procedure:
- preparation of a slurry of 2.5% dry starch by weight in pH 6.5 phosphate buffer;
- 38 g total slurry;
- Rapid Visco Analyzer cook profile of 160 rpm, 20 min at 95° C., cool down to 50° C., total run 35 minutes, with water loss during the cook being accounted for by weighing before and after cooking
- transferring of cooked paste into a tared 30-mL centrifuge tube without dilution, recording the mass of paste transferred;
- centrifuging of cooked paste at 4000 rpm for 15 minutes in a centrifuge and determination of volume of swollen granular material after decanting supernatant;
- and
- determination of specific sedimentation volume in units of mL/q by the formula
