Non-contact AFM investigation of influence of freezing process on the surface structure of potato starch granule

Effect of a Pulsed Electric Field and Osmotic Treatment on Freezing of Potato Tissue

“…It is known that the surface morphology of potato starch granules can be disordered by freezing, the surface structure of the granules became perforated and noticeable surface crushing was observed when starch granules were exposed to multiple freezing and thawing cycles or deep freezing in liquid nitrogen. [41][42][43] The most noticeable disordering of starch granule surface morphology was observed for PEF + osmotic pre-treatment. In fact, the freeze-drying procedure resulted in effective damage of starch grains and rather homogeneous distribution of starch matter inside the cells.…”

Adsorptive Properties of Biobased Adsorbents

“…The sample of native potato starch and samples modified by deep freezing/thawing process were used in this work (Szymonska et al, 2000;Krok et al, 2000).…”

Viscoelastic properties of waxy maize starch and selected non-starch hydrocolloids gels

“…The nature of the described method allows to characterize the conformation of the separate molecules, investigations of the surface as well as the properties of the individual phases in the heterogeneous systems. Krok, Szymonska, Tomasik, & Szymoń ski (2000) investigated by means of AFM changes in the structure of potato starch granules freezed in liquid nitrogen. Lukasiewicz, Ptaszek, Koziel, Achremowicz, and Grzesik (2007) determined structural properties of CMC/polaniline blends basing on AFM topographical investigation.…”
