[0001] The present invention relates to a method for producing a modified corn material having improved dispersibility and solubility in water and hot water as compared with a raw corn (corn), and a method for producing the modified corn material by the method. The present invention relates to a modified corn material, a food material comprising the modified corn material, and a dispersion stabilizer.
More specifically, the present invention relates to natural corn (corn).
While maintaining the same flavor as the material, the physical properties such as dispersibility and solubility in water and hot water are improved compared to natural corn material.For example, when used as an instant solid soup material, The present invention relates to a food corn material modified so that it can be eaten by being dispersed and dissolved in water.

2. Description of the Related Art Conventional instant soups are prepared by mixing a predetermined amount of starch, salt, other seasonings, oils and fats, granulating and drying. In this instant solid soup, a dried product of natural corn wet-ground as starch, that is, one using corn powder, is commercially available as instant solid corn soup.

However, since natural corn used in instant solid corn soup contains many components insoluble in water or hot water, when the solid corn soup is dispersed or dissolved in water or hot water, corn powder is formed at the bottom of the container. It often became so-called mamako or litter, which was inconvenient as an instant solid soup. The reason why the cone material becomes mamako or lump is that the viscosity of the slurry or paste when the cone material is dispersed or dissolved becomes considerably high.
