Buffalo's milk is traditionally used in the production of mozzarella cheese, particularly in Italy, due to its high fat content and unique flavor profile.

Lactic acid bacteria ferment lactose, the natural sugar found in milk, into lactic acid, resulting in the characteristic tart flavor and thick texture of yogurt.

Lassi is a traditional Indian yogurt-based beverage, often flavored with spices, fruits, or herbs, and served as a refreshing drink or accompaniment to meals.

Rennet, an enzyme derived from animal or microbial sources, is used to coagulate milk proteins, causing them to form a semi-solid curd, which is then cut and processed to produce cheese.

Greek yogurt is known for its thick, creamy texture and slightly tangy flavor due to the straining process that removes excess whey, resulting in a higher protein content and a more concentrated flavor.

Kefir is a fermented milk beverage produced using kefir grains, which are a complex culture of bacteria and yeasts. Milk is the primary ingredient in kefir production, and the fermentation process results in a slightly tart and effervescent beverage.

Ayran is a traditional Turkish yogurt-based beverage, often flavored with salt and sometimes mint or other herbs. It is a refreshing drink commonly served alongside meals or as a standalone beverage.

Starter cultures, typically consisting of specific strains of lactic acid bacteria, are added to milk to initiate the fermentation process. These bacteria convert lactose into lactic acid, resulting in the characteristic tart flavor and thick texture of yogurt.

Feta cheese is traditionally made from sheep's milk, although variations using goat's milk or a combination of sheep's and goat's milk are also produced. Sheep's milk contributes to the unique flavor and texture of feta cheese.

Probiotics, live microorganisms that provide health benefits when consumed, are present in yogurt and other fermented dairy products. They are known to improve digestion, support immune function, and may have other potential health benefits.

Labneh is a traditional Bulgarian yogurt-based cheese made by straining yogurt to remove excess whey. It has a thick, creamy texture and a slightly tangy flavor, and is often used as a spread or dip.

Acidification, caused by the fermentation of lactose by lactic acid bacteria, is a crucial step in yogurt production. The acidification process lowers the pH of the milk, causing the milk proteins to coagulate and form a semi-solid gel, resulting in the characteristic texture of yogurt.

Brie cheese is traditionally made from cow's milk, although variations using goat's milk or a combination of cow's and goat's milk are also produced. Cow's milk contributes to the creamy texture and mild flavor of brie cheese.

Rennet is not typically used in the production of yogurt. Acidification, caused by the fermentation of lactose by lactic acid bacteria, is the primary mechanism responsible for the coagulation of milk proteins and the formation of yogurt.

Kumis is a traditional Mongolian fermented milk beverage made from mare's milk. It has a slightly sour and effervescent flavor and is considered a national drink in Mongolia.
