Patent

CA 2470667

The invention relates to a method for producing a pregelatinized starch that has good gelling properties, which comprises the following steps: a) producing a suspension on the basis of starch and water, b) applying the suspension produced in a) to a hot roller of a roller drier, and c) isolating the pregelatinized starch obtained in b). The starch used according to the invention is potato starch with an amylose content of at least 30 % by weight. The invention also relates to the novel pregelatinized starch so produced and to its use for producing firm gels, food items, especially instant puddings, feedstuff, adhesives and paints. The invention further relates to compositions that contain such a pregelatinized starch, especially a dry mixture for producing instant puddings.

L'invention concerne un procédé pour produire un amidon prégélatinisé présentant de bonnes aptitudes de gélification. Selon ce procédé, a) une suspension est préparée à base d'amidon et d'eau, b) la suspension obtenue à l'étape a) est mise sur le tambour chaud d'un sécheur à tambour, et c) l'amidon prégélatinisé obtenu par l'opération b) est isolé. Selon l'invention, on utilise un amidon de pomme de terre dont la teneur en amylose est d'au moins 30 % en poids. La présente invention porte également sur l'amidon prégélatinisé ainsi préparé et sur son utilisation pour réaliser des gels et des aliments de consistance ferme, notamment des crèmes-desserts instantanées, des aliments pour animaux, des colles et des peintures. Cette invention concerne aussi des compositions comprenant un amidon prégélatinisé de ce type, en particulier un mélange sec pour préparer une crème-dessert instantanée.
