Explain how enzymes are used to produce vegetarian cheese.
Answer
Enzymes play a crucial role in the production of vegetarian cheese through the use of immobilized enzymes. These enzymes are mixed with alginate, forming alginate beads that are then dropped into a calcium chloride solution to solidify. The beads are collected and placed in a column or syringe, where they can interact with milk containing lactose.
In the process of making lactose-free milk, lactase is typically used. The lactose in the milk is converted into glucose and galactose, making it suitable for individuals who are lactose intolerant. The immobilized enzymes can be reused multiple times, enhancing the efficiency of the process and ensuring that lactose-free milk is produced even when enzyme is present.
