The difference between sea salt and edible salt

(1) Sea salt is thicker and more granular than salt, because it has not been processed so much. Sea salt is extracted by evaporating sea water. Salt is generally mined from underground salt mines and processed into finer crystals.

(2) Some sea salts are not as heavy as refined salt, so they can retain more trace elements.

(3) According to the origin and minerals, the colors of sea salt are different, including white, pink, black, gray and variegated. Ordinary refined salt is white fine particles.

(1) Classification of petrels:

(1) powder salt: (such as a powder salt produced in Himalayas) contains calcium, magnesium, potassium, copper, iron and other components, so it is pink. Some powdered salt contains carotene from salt-tolerant algae, which makes it more colorful. Pink salts such as Hawaiian araya salt are mixed with iron oxide in volcanic clay.

(2) Black salt: not black, but a little pink in pearl ash. Indian black salt is rich in trace elements such as sulfide and iron, and has a strong sulfuric acid taste. The black lava salt produced in Hawaii is dark in color and contains a small amount of activated carbon and volcanic rocks.

(3) Gray salt: The color of gray salt comes from the trace elements it contains or the clay of origin. "French grey salt" is produced in coastal cities of France, and it is an unfinished wet grey salt. Smoked salt is also gray, which is a new product in high-quality salt. This salt is smoked on charcoal, so the food cooked with it often smells of smoke.

(two) refined salt is iodized salt and iodized salt. In the mid-1920s, in order to curb the spread of hyperthyroidism, people began to use iodized salt. Hyperthyroidism is thyroid hypertrophy, which is mainly caused by iodine deficiency. Children with iodine deficiency will also have symptoms of physical and mental retardation.

In some areas, fluorine and folic acid are often used as salt additives. Refined salt is the most common salt. In its processing, impurities need to be removed and anti-caking agents such as calcium phosphate need to be added. The refined salt is exquisite, not only easy to weigh, but also easy to mix with food.
