Vinegar is a dilute acetic acid.
ACID CURDLING
In normal conditions milk has a pH of about 6.5-6.7 and at this pH value the casein is without protons, it has a negative charge and therefore the casein micelles are relatively soluble, because they repel each others. In an acid ambient milk coagulates, because casein has its isoelectric point at 4.6 pH, that is at this pH value it has a quantity of positive charges equal to the quantity of negative charges and the positive part of each "micelle" is attracted by the negative part of the others, causing the formation of ionic bonds among the "micelle" working against the dipole-dipole bonds with water, so that the protein precipitates in the form of demineralized casein and in the solution remain soluble calcium salts.
When milk and vinegar are mixed, the acidic vinegar will cause the milk to curdle. This is due to the acetic acid in vinegar causing the proteins in the milk to unfold and clump together, forming curds. The liquid that is left behind is whey.
the solid mass are the proteins in the milk reacting with the acidic vinegar. Sour cream is made in the same way by adding lemon juice (acid) to heavy cream. The acid will react with the protein in the cream and thicken it.

Yes, other acids like lemon juice and orange juice can also be used to make plastic from milk, in a similar way to vinegar. These acids help to curdle the milk protein, casein, which can then be separated and molded into a bioplastic material.
Sour milk can be used in recipes as a substitute for buttermilk. To make a sour milk substitute, add 1 tablespoon of vinegar or lemon juice to 1 cup of milk and let it sit for 5-10 minutes. This will curdle the milk and create a similar tangy flavor to buttermilk.
Vinegar makes milk curdle and the nature of vinegar is to not mix.
Tabasco contains quite a bit of vinegar so yes it will curdle milk due to the vinegar.
Yes, soy milk can curdle when mixed with acidic ingredients due to the proteins in the soy milk reacting with the acid.
Yes, when you add an acid, like vinegar, to milk a chemical reaction occurs. The acid causes milk to curdle. In fact, by adding vinegar to milk you can make cheese! http://www.wikihow.com/Make-Cheese-at-Home
Cheese can be made using milk and vinegar by heating the milk, adding vinegar to curdle it, straining the curds from the whey, and pressing the curds to form cheese.
When vinegar is added to milk, a chemical reaction occurs causing the milk to curdle and form lumps. This is due to the acid in vinegar causing the proteins in the milk to denature and clump together, separating into curds (solid) and whey (liquid). To show this, you can pour vinegar into a beaker of milk and observe how the milk starts to curdle and separate into curds and whey.
Yes, Camels milk does not curdle
This is a chemical change.
To curdle milk effectively for making cheese at home, you can add an acid like lemon juice or vinegar to warm milk and let it sit until curds form. Then, strain the curds through a cheesecloth to separate them from the whey.
Its relatively simple. The plastic is called casein. Basically all you need to do is curdle the milk using vinegar. See the link for more detail.
Bacteria in the milk can also cause it to curdle.
Vinegar will curdle cream or milk. If you need buttermilk for a cake recipe and have none, you can add a couple of teaspoons of white or cider vinegar per cup of milk, let it stand for about 15 minutes and it's ready to add to your batter.
