Table Salt has been a precious commodity throughout most of history, despite its simple nature. Rome’s armies were paid in salt (the origin of the word ‘salary’). Salt is a seasoning, an essential nutrient, but also a very important preservative.
Table salt is sodium chloride combined with iodine sources, stabilizers for the iodine, and anti-caking compounds to make it pour by preventing it from absorbing water from the air.
Salt (NaCl), sodium chloride, mineral substance of great importance. The mineral form halite, or rock salt, is sometimes called common salt to distinguish it from a class of chemical compounds called salts.Properties of common salt are shown in the table. Salt is essential to the health of both people and animals. Table salt, used universally as a seasoning, is fine-grained and of high purity. To ensure that this hygroscopic (i.e., water-attracting) substance will remain free-flowing when exposed to the atmosphere, small quantities of sodium aluminosilicate, tricalcium phosphate, or magnesium silicate are added.Iodized salt—that is, salt to which small quantities of potassium iodide have been added—is widely used in areas where iodine is lacking from the diet, a deficiency that can cause swelling of the thyroid gland, commonly called goiter. Livestock also require salt; it is often made available in solid blocks.
TYPES OF SALT:
All salt contains two essential elements for life — sodium and chlorine — but with varying levels of some minerals.
The real distinction between the ‘types’ of salt arises from how the salt is processed and where it comes from.Manufacturers cull sea salt directly from evaporated ocean water and salt lakes, where machines and human hands then clean and refine it.
Himalayan pink salt — which is mined from the Khewra Salt Mine in Pakistan, the second largest salt mine in the world — gets its pink color from bits of iron oxide, or rust.
Table salt and kosher salt manufacturers, on the other hand, minesalt from ancient, deep, dried up seabeds and salt deposits that were either buried or pushed up thousands of years ago by tectonic activity. Machines blast into the floors of mines to either crush and pull the salt out in rock form, or dissolve it with water and then pump out the salty solution to be dried and refined later.
USES OF TABLE SALT:
Sprinkle salt on your shelves to keep ants away.
Soak fish in salt water before descaling; the scales will come off easier.
Put a few grains of rice in your salt shaker for easier pouring.
Add salt to green salads to prevent wilting.
Test the freshness of eggs in a cup of salt water; fresh eggs sink; bad ones float.
Add a little salt to your boiling water when cooking eggs; a cracked egg will stay in its shell this way.
A tiny pinch of salt with egg whites makes them beat up fluffier.
Soak toothbrushes in salt water before you first use them; they will last longer.
Soak your nuts in salt brine overnight and they will crack out of their shells whole. Just tap the end of the shell with a hammer to break it open easily.
Add a little salt to the water your cut flowers will stand in for a longer life.
Use salt for killing weeds in your lawn.
Clean greasy pans with a paper towel and salt.
