Curd is obtained by coagulating milk in a sequential process called curdling. It can be a final dairy product or the first stage in cheesemaking . [ 1 ] The coagulation can be caused by adding rennet , a culture , or any edible acidic substance such as lemon juice or vinegar , and then allowing it to coagulate.
Cheese curd prior to pressing Silky tofu (kinugoshi tofu) Milk and soy milk are curdled intentionally to make cheese and tofu by the addition of enzymes (typically rennet), acids (including lemon juice), or various salts (magnesium chloride, calcium chloride, or gypsum); the resulting curds are then pressed.

Curd is made by bacterial fermentation of milk. In this process, lactose in milk is converted into lactic acid by several probiotic microorganisms.The species involved in the fermentation depends on the temperature and humidity of the environment and may include Lactococcus lactis, Streptococcus diacetylactis, Streptococcus cremoris, Lactobacillus delbrueckii subsp. bulgaricus and ...
Milk is skimmed to remove the fat, then the milk is soured so that the casein is precipitated as milk curd. The curd is washed (removing the whey), and then the curd is pressed to squeeze out the water (it may even be dried to a powder). The casein is mixed with alkali (usually both sodium and calcium hydroxide) to make glue.
Many soft cheeses are produced without use of rennet, by coagulating milk with acid, such as citric acid or vinegar, or the lactic acid produced by soured milk. Cream cheese, paneer, rubing, and other acid-set cheeses are traditionally made this way. The acidification can also come from bacterial fermentation such as in cultured milk. [citation ...
Dictionaries sometimes translate it as curd cheese, cottage cheese, farmer cheese or junket. In Germany, quark and cottage cheese are considered different types of fresh cheese and quark is often not considered cheese at all, while in Eastern Europe cottage cheese is usually viewed as a type of quark (e.g. the Ukrainian word " сир " syr is a ...
Milk skin or lactoderm refers to a sticky film of protein that forms on top of dairy milk and foods containing dairy milk (such as hot chocolate and some soups). Milk film can be produced both through conventional boiling and by microwaving the liquid, and as such can often be observed when heating milk for use in drinks such as drinking ...
Once the cheese curd is judged to be ready, the cheese whey must be released. As with many foods the presence of water and the bacteria in it encourages decomposition. To prevent such decomposition it is necessary to remove most of the water (whey) from the cheese milk, and hence cheese curd, to make a partial dehydration of the curd. There are ...
