CA 2518404

Methods for the production of substrate, tuber, and grain compositions containing isomalto-oligosaccharides are described. The methods comprise (a) contacting a substrate, tuber or grain containing ungelatinized starch with a maltogenic enzyme and a starch liquefying enzyme to produce maltose; (b) contacting said maltose with a transglucosidic enzyme, wherein said steps (a) and step (b) occur at a temperature less than or at a starch gelatinization temperature; and (c) obtaining a substrate, grain or tuber composition having an enzymatically produced isomalto-oligosaccharide, wherein the oligosaccharide is derived from the grain. The maltogenic enzyme can be either exogenous or endogenous to the grain. The contacting steps can be sequential or concurrent. The present invention also describes flour, oral rehydrating solutions, beer adjuncts, food, feed, beverage additives incorporating the grain compositions made as described.

L'invention concerne des procédés de production de compositions de substrats, de tubercules et de grains contenant des isomalto-oligosaccharides. Lesdits procédés consistent: a) à mettre en contact un substrat, un tubercule ou des grains contenant de l'amidon non gélatinisé avec une enzyme maltogène et une enzyme liquéfiant l'amidon afin de produire du maltose; b) à mettre en contact ledit maltose avec une enzyme transglucosidique, les étapes (a) et (b) se produisant à une température inférieure ou égale à la température de gélatinisation de l'amidon; et c) à obtenir une composition de substrats, de grains ou de tubercules comprenant un isomalto-oligosaccharide produit de manière enzymatique, ledit oligosaccharide étant dérivé du grain. L'enzyme maltogène peut être soit exogène soit endogène au grain. Les étapes de mise en contact peuvent être séquentielles ou concurrentes. L'invention concerne également une farine, des solutés de réhydratation orale, des grains crus pour bière, des aliments, des granulés, des additifs pour boisson incorporant les compositions de grains produites.
