  • the present invention relates to a molded product containing a branched starch, and more particularly to a molded product containing a branched starch having a 6-a maltosyl branched structure and / or a 6a maltotetraosyl branched structure.
  • Starch is a high molecular weight gnolecan stored mainly in the cells of higher plant seeds and rhizomes, and is generally a mixture of amylose and amylopectin.
  • Amylose is an ⁇ -1,4 glucan having a structure in which dalose is linearly bonded with ⁇ -1,4 bonds.
  • amylopectin is a linear part of ⁇ -1, 4 glucan, and usually has a structure in which ⁇ -1, 4 glucan having a glucose polymerization degree of 6 or more is branched by ⁇ -1, 6 bonds. Yes.
  • Starch swells when heated in an aqueous dispersion to form a viscous gelatinized starch, but has the property of aging and causing gelation when allowed to cool.
  • Starch has been gelatinized since long ago, and is used for food, and because it has excellent processability, low cost, and storability, it is used as the main ingredient of foods.
  • Colloid stabilizers are also widely used for the purpose of improving the physical properties and maintaining the quality of food.
  • starch is liquefied and industrially used as a raw material for dulose, isomerized sugar, maltooligosaccharide, chickenpox and the like.

  • cyclic maltosyl maltose acts on high-concentration liquefied starch or partially decomposed starch by the action of cyclic maltosyl maltose-producing enzyme formed from ⁇ -1,4 glucan.
  • Cyclic maltosyl maltose-producing enzyme was found to be derived from liquefied starch or starch partial degradation products that cause little decrease in molecular weight or increase in reducing power relative to the raw starch material. — It was found that a novel branched starch having an ⁇ -maltosyl branched structure and / or a 6a-maltotetraosyl branched structure was produced. Furthermore, it has been found that the starch has a marked aging resistance with this 6a maltosyl branched structure and / or 6a maltotetraosyl branched structure (Japanese Patent Application No. 2005-298253). As a result, the present inventors have found that the texture, texture, function, and the like can be stably maintained for a long period of time as compared with the case where ordinary starch is added.
