  FERMENTED MILK (BUTTERMILK) Introduction Fermented milk products are obtained by the controlled fermentation of milk using specific microorganisms that convert lactose into lactic acid. Buttermilk is a popular fermented milk product known for its low fat content, mild acidity, refreshing taste, and high digestibility. Traditionally, buttermilk was the liquid residue left after churning butter from cream. Modern buttermilk, however, is produced by fermenting low-fat or skim milk with selected starter cultures and is widely consumed as a nutritious probiotic beverage. History of Buttermilk The origin of buttermilk dates back to ancient times when milk was stored at ambient temperatures. Natural fermentation occurred due to the presence of lactic acid bacteria. Traditionally, after butter was churned from fermented cream, the remaining watery liquid was called buttermilk. This traditional buttermilk was commonly consumed in rural communities for its cooling and digestive pro...

  YOGURT (CURD) Introduction Yogurt is a fermented dairy product obtained by the controlled fermentation of milk using specific lactic acid bacteria. It is one of the oldest fermented foods known to humans and is widely consumed across the world due to its nutritional value, pleasant taste, and health benefits. During yogurt production, lactose present in milk is converted into lactic acid by starter cultures, resulting in milk protein coagulation, thick texture, and characteristic sour flavor. Yogurt is considered a functional food because it not only provides essential nutrients such as proteins, calcium, vitamins, and minerals, but also contains beneficial microorganisms (probiotics) that improve gut health. It plays a significant role in human nutrition, especially in regions where milk preservation is challenging. History of Yogurt The origin of yogurt dates back over 4,000 years. It is believed to have originated i...
