Abstract

Fremgangsmåte for å fremstille en stabil enzymtynnet stivelssesdispersjon kjennetegnet ved en utvalgt tynningsgrad omfattende trinnene: (a) kombinere en derivatisert kornet stivelse med et a- amylaseenzym for å danne en stivelse/enzymvelling; (b) passere stivelse/enzymvellingen gjennom en strålekoker under betingelser utvalgt for å gelatinere stivelsen; (c) behandle stivelse/enzymvellingen til fullstendig gelatering og oppnå den utvalgte tynningsgrad slik at konsentrasjonen av stivelseshydrolysatprodukt med en molekylvekt større enn l 000 000 dalton er 5 % eller størrre; og (d) deaktivere enzymet.A process for preparing a stable enzyme-thinned starch dispersion characterized by a selected degree of thinning comprising the steps of: (a) combining a derivatized granular starch with an α-amylase enzyme to form a starch / enzyme swelling; (b) passing the starch / enzyme slurry through a radiation boiler under conditions selected to gelatinize the starch; (c) treating the starch / enzyme slurry to complete gelation and obtaining the selected thinning degree such that the concentration of starch hydrolyzate product having a molecular weight greater than 1,000,000 daltons is 5% or greater; and (d) deactivating the enzyme.
