What is yogurt production?
Modern yogurt production involves culturing milk with live bacteria. The bacteria produce lactic acid which coagulates the milk proteins, making yogurt thick and slightly sour in flavor. The bacterial cultures required for producing yogurt are Streptococcus thermophilus and Lactobacillus bulgaricus.
What is the key process in the production of yogurt?
The function of the starter cultures is to ferment lactose (milk sugar) to produce lactic acid. The increase in lactic acid decreases pH and causes the milk to clot, or form the soft gel that is characteristic of yogurt. The fermentation of lactose also produces the flavor compounds that are characteristic of yogurt.
How does yogurt fermentation work?
Yogurt forms when bacteria ferment the milk sugar, known as lactose, into lactic acid. The lactic acid makes the milk more acidic (lower pH) causing the proteins to coagulate. The final taste and consistency of the yogurt can be influenced by the type of yogurt starter used and length of incubation time.
What active cultures should be in yogurt?
The basic cultures or probiotics used to make yogurt are Lactobacillus bulgaricus and Streptococcus thermophilus.
What makes yogurt yoghurt?
Yoghurt is made by adding a mixture of lactic acid bacteria to the milk. Yoghurt is made by adding a mixture of lactic acid bacteria to the milk known as the ‘yoghurt cultures’. The lactic acid bacteria used are Lactobacillus bulgaricus and Streptococcus thermophiles.
What is yogurt fermentation?
Yogurt is a milk product obtained by fermentation of milk specific microorganisms through lactic acid fermentation. It results from the action of lactic ferments, which are two specific micro-organisms for yogurt: Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus.
What are the main ingredients of yogurt?
Milk

What is a meaning of yoghurt?
: a fermented slightly acid often flavored semisolid food made of milk and milk solids to which cultures of two bacteria (Lactobacillus bulgaricus and Streptococcus thermophilus) have been added.

What kind of machine makes yogurt in the factory?
Yogurt production line The yogurt production line （yogurt processing machines） is a fully automatic production line composed of multiple machines. This production line takes fresh milk as raw material and has been treated by pasteurization and fermentation. The yogurt produced by this production line has a unique taste and rich nutrition.
Where is yogurt produced in the United States?
U.S. yogurt production in 2017 totaled 4.5 billion pounds at 170 processing plants. New York leads the nation in yogurt production, accounting for 15.7% of the total amount of yogurt produced in the United States. California is the second largest producer of yogurt. The production of yogurt requires only two ingredients: milk and live cultures.
What are the benefits of yogurt production line?
The yogurt produced by this production line has a unique taste and rich nutrition. As we all know, yogurt is a kind of healthy food, which has great benefits for the human body. So what are the benefits of yogurt compared to fresh milk?
What do you need to know about making yogurt?
The process requires double handling and incubation in the yogurt pot at est 44° C for about 5 hours before moving to a air cooled store – rapid ambient reducing to about 25° C followed by blast chilling to less than 5° C. Rapid chilling is important to stop the bacteria rapidly reproducing and causing wheying off.
