Abstract

L'invention concerne un procédé de suppression de la détérioration de la texture dans un aliment de boulangerie lorsqu'il est réchauffé, l'aliment de boulangerie contenant, dans sa pâte, une matière première en poudre qui contient un constituant (A) qui satisfait aux conditions (1) à (4), la quantité mélangée du constituant (A) par rapport à la matière première en poudre allant de 2 à 30 % en masse. Les conditions sont les suivantes : (1) La teneur en amidon est égale ou supérieure à 75 % en masse ; (2) de l'amidon dépolymérisé d'amidon ayant une teneur en amylose de 5 % en masse ou plus est contenu à 3 à 45 % en masse et le poids moléculaire de pic de l'amidon dépolymérisé est de 3×103 to 5×104; (3) le degré de gonflement à l'eau froide à 25 °C est de 5 à 20 ; et (4) la quantité contenue du composant (A) mesurée au-dessous d'un tamis ayant une ouverture de tamis de 0,5 mm et au-dessus d'un tamis ayant une ouverture de tamis de 0,038 mm est de 30 à 100 % en masse.
