In todays class we did practical work which involved taking milk and transforming it into cat milk, milk without lactose.
Method:
1) Mix 2cm^3 of lactase enzyme with 8cm^3 of 2% sodium alginate solution
2) Add this mix to 1.5% calcium chloride solution a drop at a time, this created gel like balls.
3) Use a tea strainer to separate the balls from the calcium chloride solution
4) Pack a small piece of gauze and the balls into a syringe with an attached tube of plastic going into a beaker with a tap attached to maintain control over the milk flow.
5) Then pour the milk through the balls into the beaker and test the milk for lactose levels every time around.
Unfortunately we didn't have time to make it very lactose free in our class but we our results showed us was that there was less and less lactose in the milk each time.
