AI Technical Summary
Technical Problem
Existing encapsulation methods for microorganisms are detrimental due to high temperatures, high shear forces, or the use of non-aqueous chemicals, leading to low viability and limited particle size control, especially for sensitive microorganisms.
Method used
The development of polymer capsules using water-soluble polymers like dextran, starch, alginate, and others with average particle sizes below 100 pm, formed through an all-aqueous emulsion process that maintains microorganism viability by avoiding harsh conditions.
Benefits of technology
The method allows for the production of stable, small-sized microcapsules with high colony-forming units (CFU) of sensitive microorganisms, preserving their integrity and functionality.
