## Abstract β‐Galactosidase was immobilized on chitosan using tris(hydroxymethyl)phosphine (THP) as a coupling agent to produce galactooligosaccharides (GOS) from lactose. Both the THP‐immobilized and the free enzymes were maximally achieved at pH 5.0 and the optimal temperature was 55 °C. The resi
