Making Yoghurt

The video explains the process of making yogurt, starting with milk and introducing the role of good bacteria, known as probiotics. It covers the steps of sterilizing equipment, pasteurizing and homogenizing milk, and adding lactic acid bacteria for fermentation. The fermentation process converts lactose into lactic acid, leading to coagulation and the formation of yogurt. The video concludes with interactive exercises to reinforce learning.

Explain the significance of pH in yogurt production.
