  • Processing of maltodextrins
    Patent number: 5431951
    Abstract: A method of treating maltodextrin by adding a seed material to an aqueous solution of a maltodextrin having a DE not exceeding about 6 and that is heated to a temperature of at least 70.degree. C. Addition of a seed material promotes aggregate formation and so promotes gelling, resulting in production of a firmer gel than conventionally obtainable.The invention also provides a method of treating maltodextrins by maintaining an aqueous solution or dispersion of maltodextrin having a DE not exceeding about 6 (e.g. Paselli SA2) at a temperature of less than 50.degree. C. for at least 1 hour; then heating the solution or dispersion to a temperature of at least 70.degree. C.; followed by cooling. Maltodextrin treated in this way forms a gel that is firmer in consistency than maltodextrin gels produced by conventional processes.
