PHYSICALLY MODIFIED SAGO STARCH Russian patent published in 2020 - IPC C08B30/12 

FIELD: manufacturing technology; chemical or physical processes.

SUBSTANCE: present invention relates to physically modified sago starch. Disclosed physically modified starch of sago has average molecular weight making at least 90 % of molecular weight of initial starch sago; a gelation beginning temperature, measured by differential scanning calorimetry (DSC) in demineralised water of at least 71 °C; controlled viscosity development from 100 to 600 MVU for less than 15 MVU/s; peak viscosity of at least 400 MVU and viscosity drop of less than 40 % from peak viscosity. Physically modified starch is calcined in excess water in the presence of an inhibitor of swelling or subjected to wet-heat treatment.

EFFECT: invention enables to obtain starch exhibiting an increase in the gelation onset and controlled increase of viscosity while maintaining considerable viscosity in hot and cold conditions, which makes it widely used as thickeners.
