Low-methoxy (LM) pectin gels have gained momentum in tissue engineering and drug delivery in recent years due to their excellent biocompatibility. LM pectin forms stable hydrogels by forming supramolecular assemblies with egg-box structures in the presence of divalent ions like Ca2+, generally provided by a calcium chloride (CaCl2) solution or calcium carbonate (CaCO3). In particular, the use of CaCO3 enables the preparation of LM pectin gels with controlled shape.
