This process is called curdling. It can be used to make various recipes such as soups, green beans and scallop potatoes.

Aloe vera leaves are fleshy and act as storage tissue. It contains carbohydrates, proteins, tannins and variety of acids.
There are three types of reactions postulated for the reaction between tannins (or rather Tannic acid) and proteins. 1. Tannic acid forms chemical bonds with basic amino acids in the protein chain. For example it bonds with the amino acid arginine at a pH 0f 3.5 where as it bonds with lysine at pH 7.5 when the tannic acid concentration is 2.5% 2. If the concentration of tannic acid is low (0.01% or 0.06 mM), only electrostatic interactions occur at pH7.5 resulting in the precipitation of proteins. 3. Hydrogen bonding is another mechanism by which tannins react with proteins if heavy metal are present. Google books on electron microscopy discusses these reaction and specific conditions in detail. I just did it by searching Google using the Key words "Tannin", "protein" and "reactions"
Tannins are caused by vegetation decaying and leaching into the water supply. To know if you have tannins or if it is insoluble iron run the well for a little while and fill up a white cup, if the yellowish color never disappears then you probably have tannins in your water. You are more likely to have tannins if you are located near a body of water or in a forest area. Hope this helps.
I would like to know where do taste grape tannins
Tannins may be found in all types of tea. All real tea comes from the Camellia Sinensis plant, and Tannins are an essential chemical found in the plant.
tannins
true
Tannins are phenolic compounds found in many plant species. Tannins deter against animal consumption due to a bitter taste and/or toxic consequences upon injestion. Phenolics is a category secondary metabolites. Other categories of secondary metabolites include Alkaloids, Terpenoids and Polyketides. Penolics are antioxidants with intense flavors and smells.
Potassium, calcium, lecithin, iron, niacin, magnesium, phosphorus, proteins, silicon, boron, zinc, vitamins, minerals, glycosides, tannins, triterpenes, sterols, volatile oil, choline, asparagin and inulin. And more . . .
German beers
The component of madre de cacao leaves is tannins. Tannins is also found in tea leaves and known for its staining properties.
