Abstract
In the paper, the classification of those measurement methods was presented, which were applied to measure a retrogradation phenomenon of starch with and without non-starch polysaccharide hydrocolloids (NHP) added;, among those methods, some macroscopic and molecular techniques were highlighted. The following macroscopic methods were characterised: differential scanning calorimetry (DSC), texture profile analysis, oscillatory measurements, turbidimetry, and measurements of gel syneresis; also, some examples of their current applications were given. Of all the molecular techniques used to study the retrogradation, the most frequently used methods were specifically pointed out: a nuclear magnetic resonance (NMR) and an X-ray diffractometry. Furthermore, there were specified limitations of applying other methods to study the process of starch retrogradation.
