The present disclosure relates to food grade hydrogels containing probiotics and methods of their preparation. More particularly, this disclosure describes 3D printable edible hydrogels, freeze-dried 3D printed edible hydrogels, systems for their printing, as well as, methods of preparing food grade 3D printed, freeze dried hydrogel compositions. Beneficially, the 3D printed, freeze-dried hydrogel compositions are storage stable.

3D printed, freeze-dried hydrogels and methods of making and using the same

The present disclosure relates to support structures for three dimensional (3D) printing, methods of preparing the support structures, and methods of using the support structures. In particular, the support structures comprise a hydrogel comprised of a cellulose derivative. Preferably, the support structures are biodegradable and easily removed without generating toxic waste.
