The purpose of the present invention is to provide: a loosening improver for producing a delicious starch-containing food having excellent workability while preventing the deterioration in quality, e.g., the deterioration in loosening properties, of the food during storage more effectively than ever before and a starch-containing food using the loosening improver. The present inventors have made further studies intensively for achieving the above-mentioned purpose. As a result, it is found that the loosening properties of a starch-containing food can be improved by adding a starch-containing food loosening improver characterized by containing a bean-derived water-soluble hemicellulose and a viscosity modifier and also characterized in that a solution of the loosening improver has a Casson viscosity of 500 mPa.s or less and a Casson yield value of 10 mPa.s or more upon the treatment of the surface of the food with the solution or the addition of the solution to the food. This finding leads to the accomplishment of the present invention.本發明的目的在於提供一種鬆動改良劑及使用該鬆動改良劑的含有澱粉食品,所述鬆動改良劑較以前進一步抑制於保存中鬆動性變差等品質下降,且作業性優異,用於製造美味的含有澱粉食品。本發明者等人鑒於所述課題而反覆進行努力研究,結果發現,藉由添加如下的含有澱粉食品用的鬆動改良劑,可改良含有澱粉食品的鬆動性,從而完成了本發明,所述含有澱粉食品用的鬆動改良劑的特徵在於:含有源自豆類的水溶性半纖維素及黏度調整劑,進行表面處理或添加時的溶液的Casson黏度為500 mPa·s以下,且Casson屈服值為10 mPa·s以上。無
