Really discusting smelling milk
Hoy do bacteria help change mili into yogurt?
When milk sours, it undergoes a chemical change rather than a physical change. The bacteria in the milk ferment the lactose sugar into lactic acid, changing the chemical composition of the milk. This process cannot be reversed by physical means, distinguishing it as a chemical change.
The conversion of milk to yogurt is a chemical change. The bacteria in yogurt culture ferment the lactose in the milk into lactic acid, which changes the chemical composition and properties of the milk, resulting in the formation of yogurt.
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.
Yes, when milk sours, it undergoes a chemical change due to the actions of bacteria that ferment the lactose in the milk, producing lactic acid. This change in pH causes the milk to coagulate and develop a sour taste and smell.
No, milk turning sour is a chemical change because the bacteria in the milk interact with the lactose to produce lactic acid, changing the composition of the milk.
It is not physical but rather chemical: milk sugar (lactose) is converted to lactic acid by Lactobacillus bacteria.
Bacteria in milk, specifically lactic acid bacteria, consume the sugars present in milk and produce lactic acid as a byproduct. This lactic acid lowers the pH of the milk, causing it to curdle and develop a tangy flavor.
Milk turning sour is a chemical change. It occurs due to the fermentation of milk sugars by bacteria, leading to the production of lactic acid, which changes the taste and smell of the milk.
chemical change
Bacteria convert lactose into lactic acid.
No, milk souring is an example of a chemical change. When milk sours, bacteria ferment the lactose in the milk, producing lactic acid, which changes the composition and properties of the milk. This is a chemical reaction, not a physical change.
