Abstract
A size-controllable microgel formed from pulse proteins is disclosed. The microgel has a monodisperse particle size and is formed by segregative phase separation with a solution of proteins and a solution of polysaccharide at a pH above the isoelectric point of the proteins. In some examples, the pulse proteins are lentil or fava bean proteins and the polysaccharide is alginate. The size of the microgel particles may be controlled by varying the mass ratio of proteins to polysaccharide.
Claims17
A microgel comprising pulse proteins having a monodisperse particle size between about 3 μm and about 20 μm.
A method for preparing size-controllable pulse protein microgels comprising:
- mixing a source of pulse protein with a source of polysaccharides to form pulse protein particles via segregative phase separation;
- and
- heating the mixture to induce particle gelation;
- and
- isolating the microgel particles.
