Abstract: A PROCESS FOR THE PROPARATION OF STRAIGHT-CHAIN AMYLOSES HAVING MOLECULAR CHAIN LENGTHS OF 20 TO 30 THAT HAVE NEVER BEEN OBTAINABLE HITHERTO. STRAIGHT-CHAIN LOW MOLECULAR WEIGHT AMYLOSES WHEREIN THE MOLECULES HAVE RELATIVELY UNIFORM CHAIN LENGTH ARE OBTAINED BY LIQUEFYING A STARCH SLURRY TO A RELATIVELY LOW EXTENT, RAPIDLY COOLING THE LIQUEFIED SLURRY BEFORE THERE OCCURS A SUBSTANTIAL RETROGRADATION AND SELECTIVELY DECOMPOSING AND CUTTING THE A-1,6-GLUCOSIDE BONDS OF AMYLOPECTIN CONTAINED IN THE STARCH.
