Background Salt is the common name for the substance sodium chloride (NaCI), which occurs in the form of transparent cubic crystals. Although salt is most familiar as a food supplement, less than 5% of the salt produced in the United States is used for that purpose. About 70% is used in the chemical industry, mostly as a source of chlorine. Salt is also used for countless other purposes, such as removing snow and ice from roads, softening water, preserving food, and stabilizing soils for construction.

History of Salt | SaltWorks As far back as 6050 BC, salt has been an important and integral part of the world’s history, as it has been interwoven into the daily lives of countless historic civilizations. Used as a part of Egyptian religious offerings and valuable trade between the Phoenicians and their Mediterranean empire, salt and history have been inextricably intertwined for millennia, with great importance placed on salt by many different races and cultures of people. Even today, the history of salt touches our daily lives. The word “salary” was derived from the word “salt.” Salt was highly valued and its production was legally restricted in ancient times, so it was historically used as a method of trade and currency. The word “salad” also originated from “salt,” and began with the early Romans salting their leafy greens and vegetables. History of Salt | SaltWorks

The Salt Association ::: saltsense, salt history, salt manufacture, salt uses, sodium. Key information on salt from the Salt Industry This month has seen the release of findings from yet more research into hidden salt in food. This time the target of the Low Salt Brigade was our beloved tea-break companion – the humble biscuit. But before we go on, it’s worth noting although described in the report as “hidden” the amount of salt in each biscuit is clearly shown on the nutritional information label for all to see. And although described as “research” it presumably involved someone going to the supermarket, reading the labels and noting down the number. But from this trip to the shops another national health scare has been generated – as it was discovered there is more “hidden” salt in a biscuit than there is in a fish finger and a chicken nugget. Now this comparison was clearly designed to shock – “More salt than a fish finger, you say?!” The Salt Association ::: saltsense, salt history, salt manufacture, salt uses, sodium.

salt: Definition, Synonyms from Answers salt: Definition, Synonyms from Answers Because salt is indispensable to life, acts as a food preservative, and uniquely flavors foods, humans have been preoccupied with it since the beginning of recorded history. The desire to obtain salt politically or militarily has influenced the histories of countries in Asia, Africa, Europe, South America, and the Middle East. Indeed, salt was used as a form of currency and had greater value than gold in some ancient societies.

Some of the earliest evidence of salt processing dates back to around 6,000 years ago, when people living in Romania were boiling spring water to extract the salts; a saltworks in China has been found which dates to approximately the same period. Salt was prized by the ancient Hebrews, the Greeks, the Romans, the Byzantines, the Hittites and the Egyptians. Salt became an important article of trade and was transported by boat across the Mediterranean Sea, along specially built salt roads, and across the Sahara in camel caravans. The scarcity and universal need for salt has led nations to go to war over salt and use it to raise tax revenues. Salt is also used in religious ceremonies and has other cultural significance.
