FOOD TECHNOLOGY

Detailed explanation-1: -Yogurt is a popular fermented dairy product produced by lactic acid bacteria, including Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus. During yogurt production, these bacteria produce lactic acid, decreasing pH and causing milk protein to coagulate.

Detailed explanation-2: -Bacteria can be found in many foods, particularly in dairy products like cheese or yogurt, which have been consumed for ages.

Detailed explanation-3: -It is through the process of fermentation that commercial products like yogurt and cheese are processed, involving the action of specific bacteria like LAB (lactic acid bacteria) for the manufacture of yogurt, and some fungi in the production of different types of cheeses.

Detailed explanation-4: -Yogurt is made when heated milk is combined with bacteria, specifically Lactobacillus bulgaricus and Streptococcus thermophilus, and left to sit for several hours at a warm temperature (110-115°F).
