Abstract
Native and freeze-dried potato starch granules were partially
hydrolysed to produce maltodextrins with dextrose equivalents (DE) 10, 15 and
20. Freeze-drying greatly improved the enzyme accessibility of the native
granules. Film formation properties of the hydrolysates were examined. Films
were prepared by water casting. Especially the maltodextrins, which were
produced from the native starch, were very sticky materials and could not
form any films. But after removing most of the soluble saccharides from the
maltodextrins, good quality films were produced by dissolving the hydrolysate
in water, casting on a Teflon mould and drying the solution.
