Title (EN) METHOD FOR PREPARING AN INHIBITED STARCH
(FR) PROCÉDÉ DE PRÉPARATION D'UN AMIDON INHIBÉ
Abstract:
(EN) A method for preparing an inhibited starch, wherein it comprises the steps of a) providing a slurry containing a native granular starch obtained from a starch containing raw material, b) alkalizing the slurry by adding ammonia or by adding one or more compounds having the ability to release or produce ammonia in the slurry, c) adjusting the pH of the slurry to a value between 7 and 10, d) adding at least one oxidant being a source of active chlorine to the slurry for a reaction with said ammonia, e) adding at least one organic acid or a bisulfite to the slurry with a view to eliminating any residual oxidant, off-taste, and undesired smell, and f) adding at least one antioxidant to the slurry with a view to stabilizing the achieved inhibition of the starch during prolonged warehouse storage, is disclosed, as well as a starch having increased viscosity when cooked in hard water compared to when cooked in distilled water; an inhibited starch prepared with the method according to the present invention; use of said inhibited starch in a food product; and a food product containing said inhibited starch.
(FR) L'invention concerne un procédé de préparation d'un amidon inhibé, qui comprend les étapes de a) fourniture d'une suspension contenant un amidon granulaire natif obtenu à partir d'un amidon contenant une matière première, b) alcalinisation de la suspension par addition d'ammoniac ou par addition d'un ou plusieurs composé(s) ayant la capacité de libérer ou de produire de l'ammoniac dans la suspension, c) ajustement du pH de la suspension à une valeur comprise entre 7 et 10, d) addition d'au moins un oxydant, source de chlore actif, à la suspension pour une réaction avec ledit ammoniac, e) addition d'au moins un acide organique ou d'un bisulfite à la suspension, l'objectif étant d'éliminer tout oxydant résiduel, arrière-goût et odeur indésirable, et f) addition d'au moins un antioxydant à la suspension, l'objectif étant de stabiliser l'inhibition ainsi atteinte de l'amidon au cours d'un stockage prolongé en entrepôt, ainsi qu'un amidon présentant une viscosité accrue après cuisson dans de l'eau dure par comparaison avec une cuisson dans de l'eau distillée; un amidon inhibé préparé par le procédé selon la présente invention; l'utilisation dudit amidon inhibé dans un produit alimentaire; et un produit alimentaire contenant ledit amidon inhibé.
