Parameters Tested

Sodium Chloride

As per FSS Regulations, sodium chloride content in the salt shall not be less than 96 per cent by weight on dry basis.

  • Sodium chloride content was as per the requirement in all the brands.
  • It was highest in Aashirvaad (97.95 percent) and lowest in the Tata brands (96.61 percent).
  • Sodium in Tata Salt Lite (low sodium) was found to be higher (35.87 gm/100gm) than the claimed value (33.2 gm/100gm). Sodium in Saffola Salt Plus (less sodium) was found to be 33.77 gm, less than the claimed value of 35.3 gm (this may be beneficial for consumers who want less sodium in their iodised salt).
  • Iodine

    As per FSS Regulations, iodine content in edible iodised salt at retailer level shall not be less than 15 ppm (parts per million) on dry weight basis.

  • Iodine content was as per FSS specification in all the brands.
  • It was highest in Saffola (47.78 ppm) in the ‘low sodium’ category. In regular ‘iodised salt’ category, Aashirvaad contained the highest quantity of iodine (47.63 ppm). The high iodine content in Saffola and Aashirvaad is good for consumers who need to make up for any iodine deficiency they may have.
  • Iodine content was found lowest in JMD Good Health (18.47 ppm).
  • Packaging

    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.

  • All the brands were in high-density polyethylene (HDPE) packaging
  • Marking

    The following particulars shall be marked/labelled on each pack:

  • Name of material and trademark, if any
  • Name and address of manufacturer
  • Batch or code number
  • Net weight
  • Date of manufacture
  • Iodine content
  • MRP
  • Instruction for storage
  • FSSAI license number
  • Customer-care details
  • Green dot for vegetarian status
  • Any nutritional claim is optional.

  • All brands had labelling as required.

  • For Physicochemical Parameters

    Sodium/Sodium chloride

    The minimum requirement for sodium chloride is 97 per cent.

  • ISI-marked brand Fresh & Pure did not meet the requirement. Tata I-Shakti and Reliance were very close to the minimum requirement. All other brands met the requirement. In the refined category, Tata and Nirma met the requirement fully and hence scored highest.
  • The proprietary brands Saffola Less Sodium and Tata Low Sodium did not meet their claims for sodium. Saffola Less Sodium had 36.77 per cent sodium against their claim of 35.3 per cent. Tata Low Sodium had 37.38 per cent sodium against the claimed 33.2 per cent.
  • Iodine Content

    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.

  • All the brands except Tata Salt Plus (double-fortified) were found with iodine content well above the standard requirement of 15 ppm at retail level. The iodine content in Tata Salt Plus was slightly less at 14.83 ppm.
  • In the refined category, iodine was found highest in Tata and Tata I-Shakti. A higher amount of iodine is good for consumers.
  • Matter soluble in water other than NaCl

    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.

  • In the refined category, Nirma and Tata scored highest on this parameter.
  • ISI-marked brands Ankur Gold and Fresh & Pure failed to meet the requirement. Tata I-Shakti (refined iodised salt) also did not meet this requirement.
  • Water-insoluble matter

    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.

  • Highest amount of water-insoluble matter was found in Saffola Less Sodium (1.14 per cent). However, it being a proprietary brand, the requirements set by the law are not applicable.
  • All other brands were found well within the specified limit.
  • Spencer was found to have the lowest amount of insoluble matter.
  • Moisture

    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.

  • Fresh & Pure and Patanjali, both ISI-marked brands, failed to meet the IS requirement for moisture (a maximum 0.5 per cent for refined and vacuumevaporated salts). Tata I-Shakti and Tata also did not meet the IS requirement.
  • In refined category, the lowest moisture content was found in Taal (0.03 per cent).
  • Moisture content in all other brands was within the specified limit.
  • Alkalinity

    The maximum permissible alkalinity is 0.15 per cent.

  • All the brands were well within the specified limit.
  • Physical observation

    The salt shall be free from visible contamination with clay, grit or other extraneous adulterants or impurities.

  • All brands cleared the test.
  • Particle size

    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.

  • All the brands were well within the specified limit.
  • Calcium

    The Indian Standard has set the maximum permissible limit for calcium in refined and vacuumevaporated salt at 0.15 per cent.

  • All the brands were well below the specified limit.
  • Magnesium

    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.

  • All brands except Tata showed results within the specified limit.
  • Sulphate

    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.

  • All the brands were within the specified limit.
  • Lead

    The limit is a maximum 2.5 ppm.

  • All the brands were well within the specified limit.
  • Arsenic

    The limit is a maximum 1.1 ppm.

  • All the brands were within the specified limit.
