The present invention aims to provide a quality improver that has a moderate molecular weight, a moderate viscosity, and cold water solubility, and can be advantageously used in the fields of food, cosmetics, quasi-medicinal products, pharmaceutical products, industrial products, and the like, and the use thereof. The present invention is to solve the above-mentioned problems by providing a quality improver using an α-glucan mixture obtained as the active ingredient in the following production method and the use thereof. The production method comprises gelatinizing waxy starch and causing amylase The step of performing liquefaction and the step of making α-glycosyltransferase work, the α-glucan mixture has the following characteristics (1) to (3): (1) Weight average molecular weight (Mw) In the range of 150kDa to 3,000kDa; (2) The value of the weight average molecular weight (Mw) divided by the number average molecular weight (Mn) (Mw / Mn) is 35.1 or less; and (3) Containing isomaltose at the non-reducing end Structure of α-glucan molecules. |
