Unit definition:
One Unit of sucrase activity is defined as the amount of enzyme required to release one μmole of glucose per minute from sucrose (10 mM) in sodium phosphate buffer (100 mM), pH 6.8 at 40oC. 

One Unit of β-galactosidase activity is defined as the amount of enzyme required to release one µmole of p-nitrophenol (pNP) per minute from p-nitrophenyl-β-D-galactoside (10 mM) in sodium acetate buffer (100 mM), pH 4.5 at 40oC.

Sucrase/ β-galactosidase mixture:
This enzyme mixture gives complete hydrolysis of sucrose, maltose and lactose under the defined assay conditions, with no hydrolysis of the trisaccharide, β-D-Fruf-(2,1)-β-D-Fruf-(2,1)-β-D-Fruf.

Used for removal of sucrose, maltose and lactose in the measurement of dietary fibre.

Efficacy of reducing sugar and phenol–sulfuric acid assays for analysis of soluble carbohydrates in feedstuffs.
