Dairy Product - Yogurt

Yogurt or yoghurt or yoghourt (/ˈjoʊɡərt/ or /ˈjɒɡərt/; other spellings listed below) is a dairy product (soy milk, nut milks, such as almond milk, and coconut milk can also be used) produced by bacterial fermentation of milk. The bacteria used to make yogurt are known as "yogurt cultures". Fermentation of lactose by these bacteria produces lactic acid, which acts on milk protein to give yogurt its texture and its characteristic tang.

Worldwide, cow's milk, the protein of which mainly comprises casein, is most commonly used to make yogurt, but milk from water buffalo, goats, ewes, mares, camels, and yaks is also used in various parts of the world.

Dairy yogurt is produced using a culture of Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus bacteria. In addition, other lactobacilli and bifidobacteria are also sometimes added during or after culturing yogurt. Some countries require yogurt to contain a certain amount of colony-forming units of microorganisms.

In Western culture, the milk is first heated to about 80 °C (176 °F) to kill any undesirable bacteria and to denature the milk proteins so that they set together rather than form curds. In some places, such as parts of India, curds are a desired component and milk is not pasteurized. The milk is then cooled to about 45 °C (112 °F).The bacterial culture is added, and the temperature is maintained for 4 to 7 hours to allow fermentation.

Nutritional value and health benefits

Yogurt is nutritionally rich in protein, calcium, riboflavin, vitamin B6 and vitamin B12.It has nutritional benefits beyond those of milk. Lactose-intolerant individuals can sometimes tolerate yogurt better than other dairy products, because the lactose in the milk is converted to glucose and galactose, and partially fermented to lactic acid, by the bacterial culture.

Yogurt containing live cultures has been found effective in a randomized trial at preventing antibiotic-associated diarrhea. Yogurt contains varying amounts of fat. There is non-fat (0% fat), low-fat (usually 2% fat) and plain or whole milk yogurt (4% fat). A study published in the International Journal of Obesity (11 January 2005) also found that the consumption of low-fat yogurt can promote weight loss.
