Citric acid cross-linking of starch films
WebThe amount of water released per citric acid molecule, on average, can be calculated from this data. The higher this number is, the higher the degree of cross-linking, because a molecule reacting with a Kaumera chain releases 1 water molecule, whereas a citric acid molecule reacting with another releases only 0.5 water molecules per CA molecule.
