That would be Lactic acid.
It doesn't contain an acid, it is an acid. Lactic acid to be precise.
No.
Soy milk contains many thing but citric acid is not one of them.
Yes. Lactic acid amongst some others.
Lactic acid content of milk products is due to fermentation; citric acid is only an additive from other sources.
Yes, sour milk can contain butyric acid. Butyric acid is a naturally occurring compound in dairy products like milk and butter, and is typically produced by the fermentation of lactose by certain bacteria. The presence of butyric acid can contribute to the tangy flavor and sour smell of sour milk.
Ferrous lactate consists of 1 iron atom and 2 Lactate atoms. Lactic acid is also commonly known as milk acid.
Milk contains small amounts of the alkali metal potassium.
Tartic acid is present in sour milk. Generally the source of tartic acid is lemon, therefore sour milk gives taste of lime. Therefore it is clear that tartic acid is there. Sometimes when we want to make Paneer from milk, we put 1 or 2 miligram tartic acid to make milk separate from water.
As far as I know lactose free milk does not contain lactic acid. They put in lactase to 'destroy' the lactose, which makes it lactose free! So no, and it probably won't be produced either. I hope this helps!
The only foods that are not acidic are egg white and milk.
No, lactic acid is typically produced during the fermentation process of dairy milk or other lactose-containing products by lactic acid bacteria. Rice milk, being plant-based, does not contain lactose and therefore does not produce lactic acid in the same way.
