A converted starch is disclosed, wherein it has a molecular weight, MW, of 250,000-5,000,000 g/mol, a degree of branching of 3.1-3.9%, an amylose content of at most 7%, and a DE (dextrose equivalents) value of 0.05-0.5, as well as a food product containing the converted starch, a method for the production of said converted starch, wherein it comprises the steps of adding a glucan branching enzyme, chosen from Rhodothermus obamesis or Rhodothermus marinus enzymes and enzymes from similar organisms having at least 60% amino acid sequence identity with the Rhodothermus obamesis or Rhodothermus marinus enzyme to an aqueous composition containing starch in a concentration of at least 5% by weight at a temperature of 45-80° C., until a converted starch having a branching degree of 3.1-3.9% is obtained, optionally followed by drying said aqueous solution to a powder of the converted starch, and use of said converted starch for the production of the food product.
A converted starch that includes, among its other features, an average chain length value of DP (degree of polymerization) 20-33, measured with NMR or HPAEC-PAD, a molecular weight (MW) of 250,000-5,000,000 g/mol, measured with HPSEC-MALS;
