where does salt come from that we eat
Salt Salt is processed from salt mines, and by the evaporation of seawater (sea salt) and mineral-rich spring water in shallow pools. Its major industrial products are caustic soda and chlorine; salt is used in many industrial processes including the manufacture of polyvinyl chloride, plastics, paper pulp and many other products. Of the annual global production of around two hundred million tonnes of salt, about 6% is used for human consumption. Other uses include water conditioning processes, de-icing highways, and agricultural use. Edible salt is sold in forms such as sea salt and table salt which usually contains an anti-caking agent and may be iodised to prevent iodine deficiency. As well as its use in cooking and at the table, salt is present in many processed foods.
Salt 'n' Shake According to the packet, Salt 'n' Shake was created by Frank Smith and was first sold in pubs in Cricklewood, London in the 1920s. Because the salt cellars he provided were being stolen by pub visitors, Smith began to sell the packets with a small blue sachet of salt, the tradition of which continues to this day. The brand is at present owned by Walkers.
