Taste of salt

I think you can't call salt a flavor (black and white aren't colours)

Salt has its taste and holds its taste.

It is a mineral that stays for ever.

You can mix it with any think even eat it, but in the end it comes out as the salt taste.

I can recall eating C-Rations in 1973 that were boxed in 1943, each box contained a package of salt. After 30 years it was still salt!

I believe it is possible for some types of salt to lose their flavor. Observe the following:

"Salt produced by the evaporation of sea-water in hot countries is said sometimes to lose its saline properties. The same result is also sometimes seen in impure rock-salt that has long been exposed to the air. When such is the case there can nothing be done with it but to throw it out into the highway, where men and beasts trample it down." ("Manners & Customs of the Bible" by James M. Freeman, page 335)

There are different meanings of salt - one is table salt (mostly sodium chloride), another is other "salty" seasonings such as Dead Sea salt (not mostly sodium chloride), and another refers to a group of chemical compounds that are quite diverse.

Sodium chloride can lose its salty flavor by reacting with another molecule with precipitation of another salt (add copper sulfate and you get copper chloride salt with sodium sulfate in solution). Dead Sea salt is reportedly very low in sodium chloride, so if the flavor primarily comes from that, then a very small amount of contamination could potentially change the flavor and make it worthless (this is conjecture).
