Question

How curd, yoghurt and butter milk are prepared?

Answer 1

1. Curd:
   • Made by mixing warm milk with a small amount of starting curd, which has Lactobacillus bacteria in it.
   • Lactose is turned into lactic acid by bacteria. The lactic acid coagulates the milk proteins, making curd.
2. Yogurt: 
   • Fermented milk with certain types of bacteria, such as Streptococcus thermophilus and Lactobacillus bulgaricus.
   • Lactic acid is made by these bacteria and thickens and sour tastes milk.
3. Butter Milk:
   • In the past, it was the liquid that was left over after butter was separated from cream.
   • These days, lactic acid bacteria like Lactococcus lactis or Lactobacillus species are used to process low-fat milk to make buttermilk.
