About Black Salt / Kala Namak
Black Powder & Granulate |
Black salt is also known as kala namak. It is a special type of mineral salt with a distinctive /
sulfurous flavor. Black salt
or Kala Namak is not black, but it forms brownish pink to dark violet
translucent crystals when whole, and when grand into a powder it is light purple
to pink in color because of the presence of greigite (Fe3s4,
Iron sulfide) in the mineral. It is not interchangeable with sea salt
or table salt because of its distinct flavor.
Kala Namak (Bengali
Biit lobon, Newari Be Chi, Nepali
Birae Nun, Hindi,
Urdu kālā namak; Gujarati
Sanchal; also known as sulemani namak, black salt, kala loon or black Indian
salt, is a salty and pungent-smelling condiment
used in South Asia.
The condiment is composed largely of sodium
chloride with several impurities lending the salt its colour and
smell. The smell is mainly due to its sulfur content
Production of Black Salt.
The raw material for producing black salt was originally
obtained from natural halite from mines in Pakistan, India, Nepal and Bangladesh
in certain locations of the Himalayas
salt ranges, or from salt harvested from the North Indian salt lakes
of Sāmbhar or Didwana
and Mustang of Nepal
Traditionally, the salt was transformed from its raw
natural forms into commercially sold black salt through a reductive chemical process
that transforms some of the sodium
sulphate in the raw salt into pungent hydrogen
sulfide and sodium sulfide. This involves firing the raw
salts in a furnace for 24 hours while sealed in a ceramic jar with charcoal
along with small quantities of harad seeds, aamla, bahera, babul bark,
or Sajji.
The fired salt is then cooled, stored, and aged prior to sale. Black salt is
prepared in this manner. The salt crystals appear black in colour, and are
usually ground to a fine powder which is pink in colour.
Although the black salt can be produced from natural
salts with the required impurities, it is common to now manufacture it
synthetically. This is done through combining ordinary sodium chloride admixed
with smaller quantities of sodium
sulphate, sodium bisulphate and ferric
sulphate, which is then chemically reduced with charcoal in a
furnace. Reportedly, it is also possible to create similar products through
reductive heat treatment of sodium chloride, 5-10 percent of sodium
carbonate, sodium sulphate, and some sugar.
Composition of Black Salt
Black Salt Powder |
Black salt consists primarily of sodium
chloride and trace impurities of sodium sulphate, sodium
bisulfate, iron sulfide and hydrogen
sulfide.
Sodium chloride provides black salt with its salty taste,
iron sulphide provides its dark violet hue, and all the sulphur compounds give
its slight savory taste as well as a highly distinctive smell, with hydrogen
sulphide being the most prominent contributor to the smell. The acidic
bisulfates/bisulfites contribute a mildly sour taste. Although hydrogen
sulphide is toxic in high concentrations, the amount present in black salt used
in food is small and thus its effects on health are negligible Hydrogen
sulphide is also one of the components of the odor of rotten eggs and boiled
milk
Benefits of Black Salt
Fruits Chaart |
According to medical science, black salt is full of therapeutic benefits.
It is rich in iron, and is a cure for flatulence and heartburn.
According to
doctors, black salt is the most beneficial form of salt because unlike ordinary
salt, they don't increase the sodium content of blood and are therefore
recommended for patients with high blood pressure and low-salt eating dieters.
It is also a rejuvenator while aiding digestion and improving eyesight. It is
said to aid in digestion and soften the bowel. Black salt is considered a
cooling spice in ayurvedic medicine and it is also believed to relieve
intestinal gas and heartburn.
Salt in the digestive tract extracts water from the body
by osmosis. Black salt acts as a digestive aid in reversing constipation and
allowing individuals to eliminate flatulence. Individuals may partake of the laxative in lemonade made
with lemons, ginger and the black salt. People may also roast the salt in a
copper vessel until a color change occurs, mix the salt with warm water and
drink the intestinal gas treatment. Some believe the body absorbs the iron
contained within the black salt, thus correcting iron deficient anemia.
Uses of Black Salt
Fruits & Juices |
Black Salt is used extensively in South Asian cuisines of Bangladesh, India and
Pakistan as a condiment or added to chaats, chutneys, all kinds of
fruits & Juices, raitas and many other savory Indian snacks. Chaat masala,
an Indian spice blend, is dependent upon black salt for its characteristic
sulfurous hard-boiled egg aroma. Those who are not accustomed to black salt
often describe the smell as similar to rotten eggs. Black salt is appreciated
by some vegans
in dishes that mimic the taste of eggs. It is used, for example, to spice tofu to mimic an egg
salad.
Lemon Juice |
The
hot, arid climate of the Middle East typically causes people to perspire
profusely. Along with losing water, sweat generally contains important
electrolytes, including sodium. The people of these dry sweltering atmospheres
may consume black salt in foods or liquids to ensure proper sodium/potassium balance. Women
in these desert environments often add a pinch of the mineral to fruit or
vegetable dishes and dips. The powder form may also be found as an ingredient
in mineral water.
Black
salt is considered a cooling spice in ayurvedic medicine and is used as a laxative
and digestive aid. It is used in Jammu to cure goiters. This salt is also used to treat hysteria, and for making
toothpastes by combining it with other mineral and plant ingredients.
Many
use black salt in warm bath water, replicating the hot thermal springs found
around the world. The salt and sulfur content not only reportedly alleviate
aches and pains, but also act as a natural disinfectant. Individuals use the aromatic sulfur and salt
water to heal topical inflammation
and infections. Cultures may also use the pungent mixture for clearing and
enhancing healing of the respiratory tract.
