Abstract
The present invention relates to a stabilized starch obtained by reacting under alkaline conditions a base starch having a protein content of less than 0.4% w/w with a reactant capable of forming active chlorine, wherein the reactant is used in an amount sufficient to provide between 4000 and 8200 ppm of active chlorine during the stabilization reaction.
Claims20
A method for stabilizing starch, the method comprising:
- modifying a base starch physically, chemically or enzymatically to obtain a modified starch, wherein the base starch has a protein content of less than 0.4% w/w;
- and
- reacting said modified starch with a sufficient amount of reactant that forms active chlorine such that the reactant provides between 4100 ppm (w/v) and 8200 ppm (w/v) of active chlorine during the reacting of the modified starch with the reactant, to form a stabilized starch.
A method for stabilizing starch, the method comprising:
- reacting a native starch that is root starch, tuber starch, and/or waxy starch, with a succinic anhydride to obtain a modified starch, wherein the native starch has a protein content of less than 0.4% w/w;
- and
- reacting said modified starch with a sufficient amount of reactant that forms active chlorine such that the reactant provides between 4100 ppm (w/v) and 8200 ppm (w/v) of active chlorine during the reacting of the modified starch with the reactant, to form a stabilized starch.
A method of stabilizing a starch, the method comprising:
- reacting a native waxy starch with n-octenyl succinic anhydride (nOSA) to obtain a nOSA starch, wherein the native waxy starch has a protein content of less than 0.4% w/w;
- and
- reacting the nOSA starch with sufficient sodium hypochlorite such that the sodium hypochlorite provides between 4500 ppm (w/v) and 8200 ppm (w/v) of active chlorine during the reacting of the nOSA starch with the sodium hypochlorite, to form a stabilized starch.
