Table salt

Table salt, also known as sodium chloride, is a crystalline mineral substance that is used primarily as a seasoning in food. It is one of the oldest and most ubiquitous food seasonings, and salting is an important method of food preservation.

History

The history of table salt dates back to ancient times. It was a highly valued commodity, often referred to as "white gold". Salt was used as a form of currency in some cultures, and the word "salary" comes from the Latin word for salt because it was used as payment in ancient Rome.

Production

Table salt is produced by evaporation of seawater or by mining salt deposits. The production process involves the extraction of salt from seawater or rock salt deposits, followed by purification and crystallization.

Uses

Table salt is primarily used as a food seasoning. It enhances the flavor of food and is a key ingredient in many recipes. In addition to its culinary uses, table salt is also used in a variety of industrial applications, including the production of chlorine and sodium hydroxide, key ingredients in many industrial processes.

Health effects

While table salt is essential for human health, excessive consumption can lead to health problems such as hypertension and heart disease. The World Health Organization recommends limiting salt intake to less than 5 grams per day.
