A » Milk transforms into yogurt through fermentation by introducing bacterial cultures, primarily Lactobacillus bulgaricus and Streptococcus thermophilus. These bacteria ferment lactose, the sugar in milk, producing lactic acid. This acidification process causes milk proteins to coagulate, resulting in the thick texture and tangy flavor of yogurt. The controlled environment for fermentation, typically warm temperatures, ensures optimal bacterial activity and a safe, probiotic-rich final product.

A »Milk becomes yogurt through fermentation when bacteria like Lactobacillus bulgaricus and Streptococcus thermophilus convert lactose into lactic acid, thickening the milk and giving it a tangy flavor. The bacteria feed on lactose, producing lactic acid as a byproduct, which lowers the pH and causes the milk proteins to coagulate.
