Webb2007). A further property of starch, i.e. retrogradation, in-volves the re-aligning and re-association of the AMY and AP chains in the gelatinised starch, again into an ordered crystalline structure (Batey2007; Sandhu and Singh2007; Beckles and Thitisaksakul2014). Although both AMYand AP are capable of retrogradation, the AP component ap- Webb2 maj 2024 · Starch retrogradation can be temporarily reversed by reheating loaves of bread in the oven or individual slices in the toaster. Reheating brings the bread back up to the gelatinization temperature and causes the molecules to reabsorb some moisture.
