Correct option is A.

When one adds a little amount of curd in warm milk, the entire milk gets converted into curd. This is a type of physical change. It occurs because of the Lactobacillus bacteria present in the curd. These microorganisms convert lactose present in milk into lactic acid by the process of fermentation.

When a little amount of curd is added to a bowl containing warm milk and kept for five hours, a permanent change will occur. The milk will change to curd.

Curd formation happens when the milk is at the normal physiological temperature of 32-35 degrees. This is the temperature that is ideal for the growth of the Lactobacillus bacterium that promotes fermentation which results in curd formation.

Curd contains bacteria Lactobacillus which is added to warm milk to make more curd. This bacteria need suitable temperature for its growth and multiplication that is why warm milk is used. ... Due to this reaction milk start coagulating and new curd is obtained.

The microbes present in the curd help in setting if the temperature of the mixture remains approximately between 35∘C to 40∘C. At places, where room temperature remains much below the range, setting of curd becomes difficult.

The teaspoon of curd added to milk contains the bacteria Lactobacillus. As the bacteria gets more lactose, it will produce lactic acid in the milk converting the entire milk into curd. Therefore, Lactobacillus will be able to grow in the milk producing the curd.

For the preparation of curd, we boil the milk and add little curd which acts as an inoculum. Casein protein present in the milk reacts with the lactic acid present in the curd which breaks the chemical bonds of the milk and forms new bonds thus forming curd.

The microbes present in the curd help in setting if the temperature of the mixture remains approximately between 35 o C to 40 o C . At places, where room temperature remains much below the range, setting of curd becomes difficult.

Temperature of Milk: Don't use very hot milk. It may coagulate and result in a grainy product. If the milk is a little hot, the curd will not be thick, is a bit runny with some whey in it. With cold milk, it will not set properly.

What is the setting of milk into curd? ›

Milk is converted into curd or yogurt by the process of fermentation. Milk is converted into curd by the help of bacteria called Lactobacillus. These bacteria convert lactose present in the milk into lactic acid. The lactic acid coagulates the milk protein casein and results in the formation of curd.

Curds are a dairy product obtained by curdling (coagulating) milk. The coagulation can be caused by adding rennet or any edible acidic substance such as lemon juice or vinegar, and then allowing it to set. The increased acidity causes the milk proteins (casein) to tangle into solid masses, or curds.

Dahi does not set well if you use less starter for hom*ogenized milk. On the other hand, non hom*ogenized milk needs less starter as they tend to set well and faster. Adding more will make your curd sour. So adjust the amount of starter accordingly.

The milk will be converted into fermented milk and finally into curd.

Cooking or heating curd may cause the proteins in it to denature, which means they unfold and change their structure. This can lead to changes in the nutritional value, texture and consistency of the curd.

Answer: As we know that curd is made by the bacteria called lactobacillus. This bacteria grows and reproduces to make curd in warm milk. If the milk is too hot or cold, the bacteria will not be able to work properly and the curd will not formed.

Cooking or heating curd may cause the proteins in it to denature, which means they unfold and change their structure. This can lead to changes in the nutritional value, texture and consistency of the curd.

Milk and curd come from the same family, ie animal-sourced protein and thus they should not be consumed together. It can cause diarrhea, acidity, bloating, and gas.
