Salt Crystals

Salt crystals are the common form of sodium chloride (NaCl), a mineral compound essential for life. It is typically mined from underground salt deposits or evaporated from seawater or brine springs. The crystals are purified and processed for use in food.

Salt is primarily used to enhance the flavour of foods, making them more palatable. It also acts as a preservative by inhibiting microbial growth and can affect the texture of baked goods and processed meats. It is found in a wide variety of savoury and sweet packaged foods.

Salt (sodium chloride) is not classified as a food additive in the UK. The UK government's Eatwell Guide advises adults to consume no more than 6g of salt per day. High salt intake is associated with increased blood pressure, a risk factor for cardiovascular disease, according to the NHS. The World Health Organization (WHO) also recommends limiting salt intake. While essential in small amounts, excessive consumption is a public health concern.
