casein hydrolysis
Milk is generally neutral in pH, typically around 6 to 7, so it does not significantly affect blue litmus paper. When blue litmus paper is exposed to milk, it will remain blue, indicating that there is no acidic property present to change its color. If the milk were to spoil and become acidic, it might turn the blue litmus paper red, but fresh milk will not.
Milk of magnesia is basic, so it will turn red litmus paper blue and have no effect on blue litmus paper.
Evaporated milk is a white-colored liquid, so if it turns red under red litmus paper, it indicates that the milk is acidic. This change in color suggests the presence of acidic substances in the evaporated milk, which can be detected by red litmus turning red in an acidic environment.
Sour milk is acidic. Red litmus paper should not change.The sour part of sour milk is lactic acid. As litmus paper turns red when exposed to acidic compounds, litmus paper that is already red should not react when exposed to lactic acid.
Lactobacillus a bacillus bacteria used in curdling of milk.
Bacillus subtilis will typically produce an alkaline reaction in litmus milk, turning it pink or purple. This is due to the bacterium's ability to break down lactose and produce ammonia. Additionally, Bacillus subtilis may also cause coagulation of the milk proteins, resulting in a solid clot formation.
Litmus milk medium is skim milk to which the dye litmus has been added. Litmus is both a pH indicator and a redox indicator. It is pink at pH < 4.5, purple in middle pH's and blue at pH > 8.3. As a redox dye, in the absence of oxygen (reduced state) it's colorless (white due to milk) and in the presence of oxygen (oxidized state) it is purple.
Blue litmus paper remains blue when dipped in milk of magnesia because milk of magnesia is basic in nature.
Red litmus paper will turn blue in the presence of milk, indicating a basic pH. Blue litmus paper will remain blue, as milk is not acidic enough to change its color.

Litmus paper is not typically sufficient for testing the pH of milk. To accurately test the pH of milk, you can use a pH meter or pH strips that are specifically designed for testing the pH of food and beverages. These tools provide more accurate and precise measurements than litmus paper.
Litmus milk contains several components such as; lactose (milk sugar) casein (milk protein) and Litmus ( Ph indicator) that can be metabolized. Thats why it is considered a good differential medium

Milk of magnesia is chemically known as magnesium hydroxide. Although this compound isn't very water soluble, the small amount that does dissolve acts as a base. Thus, milk of magnesia is somewhat basic, and litmus paper would turn blue if exposed to it. Nice....
i think its neither a base nor a acid . i thinks its neutral
