Description

  The present invention relates to a method for producing a thickener composition in which the formation of lumps is suppressed even when used in a high temperature liquid, and more specifically, to (a) a powdery raw material containing a polysaccharide thickener as a main component B) spraying an aqueous solution containing guar gum or tara gum as a binder solution to obtain a granulated product; (b) obtaining a mixture of the granulated material obtained in step (a) and a solubilizing agent; And (b).

  Those who have difficulty in swallowing and swallowing food and drink due to aging and the like have a risk of causing an error that may cause food to flow into the trachea accidentally, especially when eating food with a low viscosity. In order to prevent this aspiration, a toromi modifier is used which imparts a viscosity suitable for swallowing to a food having a low viscosity. As toromi modifiers, polysaccharide thickeners such as xanthan gum are used as a thickening component. However, when the powder of the polysaccharide thickener itself comes into contact with water, the contact surface starts to swell rapidly, adjacent particles aggregate, and so-called "" having a portion not in contact with water inside the aggregate. "Dama" form. The polysaccharide thickener which formed a lump reduces solubility, and can not provide sufficient viscosity to food and drink.

  In order to suppress the formation of this lump, the polysaccharide thickener is granulated with a powder other than polysaccharide thickener, and the polysaccharide polysaccharide particles are inhibited from adhering to adjacent polysaccharide particles by swelling. To reduce the formation of dams. In this granulation, a substance used to bind particles is called a binder, and in preparation of a thickener composition used as a toromi modifier etc., various binders are used for the purpose of improving aggregation suppression. It is used.

  Patent Document 1 discloses a technique in which a dextrin aqueous solution is sprayed as a binder solution to granulate polysaccharide thickener. Patent Document 2 discloses a technique for granulating a polysaccharide thickener using a modified starch aqueous solution as a binder solution.
