PROBLEM TO BE SOLVED: To provide a cloudiness-imparting agent which easily imparts a feeling of cloudiness without causing a feeling of incompatibility to taste and texture which the food and drink have and to provide a method for imparting cloudiness to food and drink by making use of the cloudiness-imparting agent.SOLUTION: By using food-grade crosslinked starch, the feeling of cloudiness is quite easily imparted to food and drink without causing a feeling of incompatibility to the taste and texture which the food and drink originally has. In this case, the average particle size of the starch concerned is 8 μm or smaller when its 5 mass% aqueous suspension is heated to 90°C and then cooled to 30°C, and its maximum viscosity at 25 mass% is 2,000 BU or smaller when measured by a Brabender-amylograph method.COPYRIGHT: (C)2013,JPO&INPIT【課題】 飲食品の有する舌触りや食感に違和感を及ぼすことなく白濁感を簡便に付与することのできる白濁化剤及びそれを利用して飲食物を白濁させる方法を提供すること。【解決手段】 5質量%の水懸濁液を加熱して90℃達温後30℃まで放冷したときの平均粒子径が8μm以下であって、25質量%で測定したブラベンダーアミログラフの最高粘度が2000BU以下である食用架橋澱粉を使用することにより、飲食品の本来有する舌ざわりや食感に違和感を及ぼすことなく、易とも簡便に飲食物に白濁感を付与することができる。【選択図】なし
