Salt: Typologies, Properties and Colors

Salt: Typologies, Properties and Colors

Salt is a very present element on Earth, both in the environment and within living organisms. It is found both in the natural state, in the form of Sea salt or mineral salt, and in various industrial products and within the human body, present in the quantity of about 250 grams. It is Not to be understood only "kitchen Salt" but also that contained naturally in all foods of the diet, especially in preserved foods.

Chemically is sodium chloride salt (NaCl), consisting of 40% Sodium (Na) and 60% Chlorine (Cl). Sodium chloride is a natural source of one of the basic flavors and always appears in the kitchens and on the tables as an essential condiment in every culture and in every time. An adult human being contains about 90 grams of sodium, which is the main ion in extracellular fluids and participates in a large number of physiological processes. Instead, chlorine abounds mainly in liquids inside cells. Both are essential for our survival and the safety range related to their needs is 0,575-3.5 grams/day for sodium and 0.9-5.3 grams/day for chlorine, corresponding to about 1.5-8 grams/day of sodium chloride. Difficult to experience a shortage of these Salts, on the contrary there is often an excessive intake: in Italy The average consumption of salt is 12-15 grams/day, decidedly higher than the values considered safe (it should not be considered only the simple Salt used as a condiment at the table but also the so-called "Hidden salts": bread, pizza, sausages, packaged or pre-cooked products, ready-made soups, nut...)

Salt on The Market

Once the only kitchen salt known by the average customer was the Classic white salt "big or up" (normal or iodized), nowadays in all supermarkets you can choose also according to color, characteristics, shapes of crystals.
The various salts differ in the content of other substances (trace elements other than chlorine and sodium) that can impart particular colour, taste and aroma to the product, with variations of the sodium chloride content that can go from 85% to 99.9% of the total weight.
Very often these trace elements are associated with curative properties that are not entirely founded by inducing unskilled consumers to abuse it (the consumption of salt, whatever it may be, must be modest).
The characteristics of the crystals, the different and peculiar colours, the aromas and flavours, naturally present or added, make certain types of salt suitable to finish with taste in the kitchen.
