Thickening composition and method for producing same

By means of a step for mixing/dissolving dextrin and a metal salt in water, homogenizing, and then drying to obtain dextrin encapsulating the metal salt, and by adding the dextrin encapsulating the metal salt to a thickening polysaccharide and then mixing or pelletizing the result, it is possible to produce a thickening composition that contains a specific amount of the thickening polysaccharide and the dextrin encapsulating the metal salt and that has favorable dispersion properties, raises viscosity rapidly, and has a superior thickening effect. It is possible to provide a thickening composition that, in a wide range of foods and beverages containing water such as water, tea, soft drinks, milk beverages, soups, high density liquid foods, and the like, has favorable dispersion properties, raises viscosity rapidly, and has an improved thickening effect per unit mass. 通过将糊精和金属盐混合溶解在水中而均质化后，进行干燥而得到封入有金属盐的糊精的工序，以及将该封入有金属盐的糊精添加至增粘多糖类并进行混合或造粒，从而能够制造以特定量包含封入有金属盐的糊精和增粘多糖类的增粘用组合物，该增粘用组合物的分散性良好，粘度的上升快，且增粘效果优异。前述增粘用组合物
