Casein in milk needs to be converted to curd, which is essentially coagulated casein protein, in order to make it easier to digest and for better nutrient absorption. Curd formation also helps in improving the texture and flavor of the milk. Additionally, curd contains beneficial probiotics that aid in digestion.

What is the useful microorganism present in curd?
Lactobacillus casei is the bacterium present in curd. It produces lactic acid, which in turn reduces the pH and coagulates milk proteins (primarily casein) forming curd.
Which bacteria helps milk to change into curd?
Rennin deactivate the casein micelles in milk, causing a distinct separation of curd protein (solid) and whey protein (liquid).
What happens when casein is heated?
When casein is heated, it undergoes denaturation, which causes it to unfold and form new interactions with water molecules, resulting in the formation of a gel-like structure. This is commonly seen when making cheese, as casein proteins coagulate and form a solid curd with the expulsion of whey.
Why the conversion of soluble milk protein caseinogens into insoluble protein casein is necessary?
Rennin clots or curdles milk proteins by converting the soluble protein caseinogen into insoluble casein. This is necessary because soluble milk proteins would pass through the stomach to the duodenum as water and would not be digested by pepsin. Insoluble casein remains long enough in the stomach to be digested by pepsin.
Does water dissolve in casein?
No, water does not dissolve in casein. Casein is a protein found in milk that is insoluble in water. However, casein can form a colloidal suspension in water, known as casein micelles.
Why curd is added to warm milk?
because of a bacteria called casein
How many calories in 3 heaped tablespoon of curd?
On average, milk contains about 3.4% protein. 20% of that is Whey, and 80% is casein. It is the casein in the milk that produces the curd. Therefore, at least 2.72% of the milk used to make the curd will be protein. The curd should theoretically be about 15-30% protein

Why does pH of milk change on turning into curd?
The pH of milk decreases when it turns into curd because the bacteria used in the fermentation process produce lactic acid as they consume the lactose in the milk. This accumulation of lactic acid lowers the pH of the milk, which helps in the coagulation of milk proteins to form curd.
Is there good protein in milk or curd?
Yes, dairy products contain complete proteins although some people are allergic to casein.
What is object of tempring during casein making?
The object of tempering during casein making is to control the moisture content of the curds and ensure proper formation of the curd structure. Tempering helps to achieve the desired texture and consistency in the final casein product.
Why the conversion of soluble milk protein caseinogens into insoluble protein casein is necessary?

Insoluble casein remains long enough in the stomach to be digested by pepsin.
Explain why curd forms when milk sours?
The curd is the fat in the milk that sticks together. ------------------------------------------------------------------- I think it is the proteins rather than the fat that are responsible for the formation of curd - after all you can get fat free curd cheese.
What is the difference between casein and caseinate?
Casein is a family of related proteins found in milk and cheese, known for its slow digestion and ability to form a gel or curd. Caseinate, on the other hand, refers to the salt form of casein that is created when casein is combined with an alkali, making it more soluble in water. This solubility enhances its use in various food products and nutritional supplements. Essentially, caseinate is a processed form of casein designed for easier incorporation into liquids.
What is the difference between acid and rennet curds?
Acid curd-Is Lactic Acid or other organic acids cause precipitation of the milk protein casein as calcium caseinate to form and insoluble clot. The clot is hard and will not retract from the walls of the test tube. An acid curd is easily identified if the tube is inverted and the clot remains immobile. Rennet Curd-- Some organisms produce rennin, an enzyme that acts on casein to form paracasein, which in the presence of calcium ions is converted to calcium paracaseinate and form an insoluble clot. Unlike the acid curd, this is a soft semisolid clot that will flow slowly when the tube is tilted.
