Resumen:
Pre and post gelatinization
rheology of native and acetylated potato starch was measured. The
starch was acetylated at the laboratory. Acetylating of starch granules
was confirmed by means of Infrared Spectroscopy. Gelatinization was
studied by means of optical microscopy and viscosity measurements.
Finally, gelatinized starch rheology results were fitted using a power
law model and compared with the previous results obtained from
literature. The change in the amylose content was determined, as well
as the crystallinity before and after chemical modification.
