CONVERTED STARCH AND FOOD COMPRISING SAID CONVERTED STARCH

A converted starch is disclosed, wherein it has a molecular weight, M.sub.W, 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.

Method for preparing modified starch and use thereof

Disclosed herein are methods for preparing modified starches, and uses thereof, and relates to the technical field of starch preparation; modifying a gelatinized starch suspension with β-amylase; after inactivating the β-amylase, further modifying with a branching enzyme, after inactivating the branching enzyme, further modifying with pullulanase, after inactivating the pullulanase, precipitating a resulting enzymatic hydrolysate with an alcohol to obtain precipitates; and drying the precipitates to obtain the modified starch. The methods disclosed a starch is modified remarkably, herein substantially increase the number of linear chains with a degree of polymerization DP6-11 in the starch chains and, thus, significantly increase the content of resistant starch in the modified starch—thereby facilitating the use in foods and medicaments.

Wheat with increased resistant starch levels

A series of independent human-induced non-transgenic mutations found at one or more of the SBEII genes of wheat; wheat plants having these mutations in one or more of their SBEII genes; and a method of creating and finding similar and/or additional mutations of SBEII by screening pooled and/or individual wheat plants. The seeds and flour from the wheat plants of the present invention exhibit an increase in amylose and resistant starch without having the inclusion of foreign nucleic acids in their genomes. Additionally, the wheat plants of the present invention exhibit altered SBEII activity without having the inclusion of foreign nucleic acids in their genomes.
