Method:
1. Mix 2cm3 of lactase enzyme with 8cm3 of 2% sodium alginate solution in a syringe.
2. Drop by drop add the alginate and enzyme mixture from the syringe into a beaker containing 1.5% calcium chloride solution. Allow the beads to set for 10 minutes.
3. Use a tea strainer to filter the beads that form the calcium chloride solution.
4. Take a syringe with an aquarium airline tubing of 4mm in width and 10cm in length, then attach an adjustable Hoffman clip to the tubing.
5. Put a small nylon gauze inside the end of the syringe.
6. Attach the syringe onto retort stand using a clamp in an upright position.
7. Use a test strip to detect glucose presence in the milk. (glucose should not be present)
8. Pour the milk through the syringe slowly by tightening the Hoffman clamp.
9. Use a test strip to detect glucose presence. (glucose should be present)
10. Repeat this method until all the lactose is split into glucose and galactose.
