Clean label stabilized buckwheat starch

A process for preparing a clean label stabilized buckwheat starch from native buckwheat starch, wherein said native buckwheat starch is a starch portion which has been previously extracted from buckwheat groat or flour recovered from buckwheat Fagopyrum esculentum grains, the process comprising the steps of:

• a) preparing a suspension of native buckwheat starch in an aqueous medium at a temperature T1 comprised between room temperature and 50° C.;
• b) heating the aqueous suspension up to a temperature Ts not exceeding 60° C., being Ts comprised in the range from 53° C. to 58° C., said heating step comprising:
• i. a first stage of slow heating, at a rate comprised between 0.2° C. and 5° C. per hour, heating stepwise from T1 up to said temperature Ts, said temperature Ts comprised in the range from 53 to 58° C. and,
• ii. a second stage of heating at said temperature Ts for a time which is at least 30 minutes, so as to obtain the stabilized buckwheat starch,
• c) separating the stabilized buckwheat starch from the aqueous medium;
• d) drying said stabilized buckwheat starch;
• and
• e) recovering said stabilized buckwheat starch,
• wherein the process is carried out without using chemicals.
