The material shall be packed in food-grade plastic. The thickness of the plastic film used for packing shall be not less than 50 microns.
The following particulars shall be marked/labelled on each pack:
Any nutritional claim is optional.
The minimum requirement for sodium chloride is 97 per cent.
The mandatory requirement for iodine content in salt is not less than 15 parts per million (ppm) at retail/consumer level and 30 ppm at manufacture level.
|Matter soluble in water other than NaCl||7|
FSS Regulations have specified the requirement as not more than 3.0 per cent for iodised salts and 2.5 per cent for fortified salts. As per Indian Standard, the limits are 3 per cent for iodised salt and 1 per cent for refined and vacuum-evaporated salt.
Water-insoluble matter refers to mineral salts contained in salt and solid brine (water-insoluble Comparative Test CONSUMER VOICE Febru ary 2017 • 13 impurity). Water-insoluble matter is also known as insoluble residual material. FSS Regulations and Indian Standard require that water-insoluble matter in salt is not more than 1.0 per cent by weight on dry basis.
Moisture generally refers to the presence of water in a product. It may be noted that less amount of moisture is better as it translates into a longer shelf life for the product. As per FSS Regulations, moisture content shall not be more than 6 per cent in iodised salt and not more than 1.5 per cent in double-fortified salt. As per Indian Standard, maximum moisture content is 6 per cent for iodised salt and 0.5 per cent for refined and vacuum-evaporated salts.
The maximum permissible alkalinity is 0.15 per cent.
The salt shall be free from visible contamination with clay, grit or other extraneous adulterants or impurities.
As per Indian Standard, a minimum 95 per cent (by mass) of the material shall pass through a 1,000-micron sieve. Also, not more than 10 per cent (by mass) shall pass through a 150-micron IS sieve.
The Indian Standard has set the maximum permissible limit for calcium in refined and vacuumevaporated salt at 0.15 per cent.
As per Indian Standard, the maximum limit for magnesium is 0.10 per cent in refined and vacuum evaporated salt. FSS Regulations have set the same requirement for double-fortified salt.
For sulphate, the Indian Standard has specified the maximum permissible limit as 0.60 per cent for refined and vacuum-evaporated salt, and 1.1 per cent for double-fortified salt.
The limit is a maximum 2.5 ppm.
The limit is a maximum 1.1 ppm.
