Edexcel B3 Biology Higher Tier

Yoghurt Production

  • Milk is heated for sterilization. This means that any existing bacteria is killed off.
  • Then it stirred thoroughly, and milk protein is added. 
  • Then whilst the milk is warm, the starter culture (Lacobacillus Bacteria) is added. (It is important to keep the mixture warm so the bacteria grow, reproduce and ferment)
  • *The Lactobacillus Bacteria then ferments the sugar Lactose*, into Lactic Acid.
