The invention describes the cost effective process for the preparation of a mixture of salts having low sodium salt (health salt) contain and exclusively derived from vegetable sources which have desired sodium chloride: potassium chloride ratio and traces of micronutrients including iodine, said salt is white in color and free flowing in nature.

Low sodium salt of botanic origin

The invention describes the preparation of nutrient-rich salt from high salt-accumulating and edible oil-bearing salt tolerant plants in a way that allows simultaneous recovery of both sail and oil, the plants are routinely irrigated with seawater and occasionally with seawater enriched with salt bitterns and/or other types of wastes/by-products containing essential nutrients to raise the level of such nutrients in the plant.

Preparation of nutrient rich salt of plant origin

The present invention relates to recovery of industrial grade potassium chloride and low sodium edible salt from bittern as part of an integrated process. The process comprises, mixing low sulphate concentrated feed bittern (a by-product of salt industry) of density 31.5 to 32.5° Be (sp.gr. 1.277–1.289) with high density end bittern of density 36.5 to 37.5° Be′ (sp.gr. 1.336–1.35), thereby producing low sodium carnallite, from which industrial grade potassium chloride is produced. The resultant bittern is evaporated in forced evaporation system, thereby producing crude carnallite, from which low sodium salt that would be beneficial to persons suffering from hypertension is produced. When sulphate-rich bittern is used, such bittern is desulphated with CaCl2 that is generated from carnallite decomposed liquor through reaction with lime, and wherein low B2O3-containing Mg(OH)2 is a by-product. The entire content of potassium in feed bittern is recovered in the process of the invention.

Simultaneous recovery of potassium chloride and KCL enriched edible salt

The invention relates to fagopyrum tararicum low-sodium salt. The fagopyrum tararicum low-sodium salt is characterized in that appropriate-proportion natural plant components such as fagopyrum tararicum flour, chrysanthemum extract, folium mori extract, radix puerariae powder, semen sesami nigrum powder and green tea powder are added on the basis of the conventional components such as sodium chloride, potassium chloride, magnesium sulfate and potassium iodate of salt; by the synergic effect of the components, the prepared fagopyrum tararicum low-sodium salt has a pure saline taste and has effects of regulating blood sugar, calming the liver and lowering blood pressure and promoting blood circulation and lowering lipid; the sodium chloride mass percentage of the fagopyrum tararicum low-sodium salt is lowered to 55-65%, the sodium chloride mass percentage of existing reaches up to 95-98%, the sodium ion content is greatly reduced, the problems that diseases such as kidney disease, cardiovascular disease and osteoporosis due to the fact that a person eats the high-sodium salt for a long time in the prior art can be avoided effectively, and the fagopyrum tararicum low-sodium salt has the healthcare effects of lowering blood pressure, lowering blood sugar, lowering blood lipid and improving microcirculation and conforms to the requirement of modern healthy diet.

Fagopyrum tararicum low-sodium salt

Quantitative table salt and preparation method thereof

A multi-element low-sodium nutritive salt with health-care function is prepared from vacuum crystallized and refined salt through crushing, sieving by 1.25 mm mesh, proportionally mixing with heptahydrated magnesium sulfate and potassium chloride, which have been pulverized and sieved by 1 mm mesh, mixing again while spraying the mother liquid of potassium iodate and sodium selenite on going through automatic distributor, baking at 80 deg.C in suspension state by hot air, sieving by 1 mm mesh, and mixing with activated calcium and zinc lactate in a helical cone type mixer. Its advantages are I, Ca, Zn and Se enriched nutrition, low content of sodium chloride and health-care function.
