Why is lactic acid in milk?
Lactic acid is naturally produced by bacteria in milk through the process of lacto-fermentation. These bacteria convert lactose, the sugar in milk, into lactic acid, which helps to preserve the milk and gives it a slightly tangy taste.
How is bacteria helpful to people four ways?
Bacteria in our digestive tract help break down food so that we can assimilate it. Bacteria in the soil help break down soil nutrients so that plants can assimilate it. Bacteria in milk help turn milk into cheese. (That's all I've got right now.)
How does milk spoil?
Lactic acid bacteria ferments the lactose in the milk turning it to lactic acid. The lactic acid lowers the pH value of the milk changing its consistency and in some cases making it unpleasant to consume, depending on the quantity and type of bacteria culturing in the milk can make you very sick. Cooking the milk will kill most bacteria, however different bacteria produce different types of toxins that will not be neutralized by cooking.
Today you use a process of heating liquids to prvent spoiling by bacteria and othe microorganisms What is that process called and for what food is it used?
pasteurization, this is mainly used for milk or milk products.
How yogurt is made is it a chemical or biochemical reaction?
Yogurt is made through a biochemical reaction involving lactic acid bacteria fermenting milk sugars. The bacteria convert lactose into lactic acid, which thickens the milk and gives yogurt its tangy flavor. This process is driven by enzymes produced by the bacteria.
Which bacteria helps in curdling of milk?
The bacteria which help in curding of milk is lactobacillus.
What type of acids are in yogurt?
Yogurt typically contains lactic acid, which is produced by the fermentation of milk by friendly bacteria such as Lactobacillus bulgaricus and Streptococcus thermophilus. These acids contribute to the tangy flavor and help preserve the yogurt by inhibiting the growth of harmful bacteria.
Why is lactic acid in milk?

What fluid is good to help preserve a dislocated and or fractured tooth?
Place a fractured or dislocated tooth in milk to temporarily preserve it.
How does pasteurisation affect the bacteria milk?
Hoy do bacteria help change mili into yogurt?
What happens when you make curd from milk?
When you make curd from milk, the milk ferments due to the introduction of good bacteria like Lactobacillus. This bacteria converts the lactose in the milk into lactic acid, which thickens the milk and gives it a tangy flavor. The result is a creamy, tangy product known as curd or yogurt.
How does bacteria affect the pH in milk?
Bacteria in milk causes milk to sour by changing lactose to lactic acid. This causes the pH to drop and once the pH drops low enough, the proteins in the milk will curdle.
The difference between bacterial count of UHT milk and pasteurised milk?
UHT milk is sterilised at 142°C for 2 - 3 seconds. There should not be more than 10 bacteria per ml of product. Pasteurised milk is heat treated at 72°C for 15 seconds. There should be a maximum of 10000 bacteria per ml of product.
Is bacteria helpful?
Bacteria can be helpful as it is found in foods like Yogurt and milk that can help you grow. So the answer is yes.
