Therefore, there is TECHNICAL FIELD a limit on the use amount of the starch having a low crosslink ing degree. In addition, processing of the starch utilizing a The present invention relates to a starch gel-containing chemical reaction also has such problems that there is a strict food, a starch having a high viscosity and a gel forming legal restriction on a processing method and a processing ability, a food containing the starch, and a method of produc degree so as to secure safety, and that it is not necessarily ing thereof. More particularly, the present invention relates to 10 Suited to needs of consumers who require security and safety. a method of producing a starch gel-containing food using an For the purpose of deigning these processed foods, it is enzyme capable of improving a gel forming ability of a urgently necessary to develop a processing technique to starch. obtain a processed Starch which exhibits various physical properties and has high safety. BACKGROUND ART 15 As a result of intensive studies, we have found that a food with rich elasticity, crispy sensation and the like can be pre With diversification of foods, foods having various shapes, pared by adopting the steps of treating starch granules with a physical properties and textures have been required. Particu starch hydrolase or a glycosyltransferase in advance; then larly, intense interest has recently been shown towards melt in mixing the resultant with a food material and water; and mouth and texture as important physical properties for the heating the mixture. purpose of designing foods. Also in the fields related to A starch is a material utilized for various purposes and the deglutition and care toward which intense interest has most important function thereof is the thickening function recently been shown, texture has been studied as important and the gel forming function. Particularly in the food industry, physical properties. the thickening function and the gel forming function of the In the case of designing processed foods, utilization of a 25 starch are widely utilized for forming the shape, physical gelling agent is important so as to improve texture and physi properties and texture of a food. The structure of a starch cal properties, and it is possible to develop various products delicately varies depending on plant from which the starch according to how to use. derived (for example, corn, potato, wheat, and cassava). As a For the purpose of altering physical properties of foods, result, the thickening function and gel forming function also various gelling agents have hitherto been added to food mate 30 vary depending on the plant from which the starch derived.
