Lactase, also known as β-galactosidase or β-D-galactoside galactohydrolase, catalyzes the breakdown of lactose into one molecule of glucose and one molecule of galactose. Meanwhile, lactase also exhibits transgalactosylation activity.
Neutral lactase has an optimum pH range of 6.0–7.0 and is derived from Kluyveromyces lactis. It delivers the highest activity in neutral dairy products such as milk and is widely applied in the industrial production of low-lactose milk and liquid dairy products.

Neural lactase is fermented from Kluyveromyces lactis, Activity is expressed by NLU/g, it is in colorless ~ deep brown liquid. Normal use in liquid milk. It is Enzymes react in vitro.
The optimum pH & temperature
Dosage recommendation depends on below conditions:
1. 37℃ Reaction Processing Technic
Sterilized milk → add neutral lactase 2500NLU/g 1%-2% (dosage based on the milk weight) → 37℃, enzymatic reaction 6-8h → inactivation → package
2. 9℃ Reaction Processing Technic
Sterilized milk → add neutral lactase 2500NLU/g 1%-2% (dosage based on the milk weight) → 9℃, enzymatic reaction 20-24h → inactivation → package
