    Health hazard due to chemicals in cooking salt

    Worried about health hazards due to chemicals in cooking salt? Looking out for the list of chemicals and their impact? Find advice from experts here to resolve your queries.

    It is widely believed that some chemicals are used in cooking salt as cleaning agent. Specifically it is understood that a chemical called caustic soda is used for cleaning the salt. Now the price of the particular chemical is Rs. 33000 per tonne but before GST it was only Rs.11000 per tonne. We do not know any other chemicals used for cleaning the salt. My doubt is whether it may be a true one and if it is a true one what will be the health hazard if we use such salt without knowing. How could we overcome this? Can any body explain?

  • Salt made out of uncontaminated sea water is the best salt to be used in food. It contains about 80 micronutrient minerals including iodine in the form of potassium Iodate or potassium Iodide. This is a very good ingredient to be used in foods. Even the well advertised Iodide salt also not as good as as salt made out of salt water. It contains about 97.5% salt and 2.5% other chemicals which will help us in maintaining balance in salt content . As far as my knowledge goes this is the best salt that can be used.
    But table salt is made by purifying the salt by chemical process where they will be removing all micronutrients and adding some chemicals for anti caking and free flow. Iodine is also added by spraying potassium iodide or iodate. This salt is not good to be used by blood pressure patients.
    I have read somewhere this unrefined salt from sea water is the best and it may even lower you blood pressure.
    My suggestion is to get salt crystals and powder it and use it rather than using refined salt.

  • I am not aware of caustic soda is whether used for cleaning the salt. My current knowledge is that mainly water and more concentrated salt water is used to wash the mined or harvested salt for further cleaning and concentration. As the top heap after evaporation under sun is usually harvested, the major impurities get settled down . The harvested salt is further washed with good water or good concentration salt water to clean and keep the concentration and content. I am not aware of any use of caustic soda during the process. I am not able to understand scientific logic about mentioned use of caustic soda anywhere in the process. In fact caustic soda is manufactured by electrolysis of salt (sodium chloride).

    Established manufacturers of iodised or common salt, are subject to quality control and they have to display the ingredients on the package label.Harmful chemicals are not allowed to contaminate the common salt used for food and human consumption.

    However even if we extremely assume that there may be traces of caustic soda in the common salt we use, because of the minute quantum of salt we use the impurities also will be very very minute in quantum. Moreover, as cooking involves a laborious process of addition of various ingredients and water, even the minute quantity of caustic soda, if at all present, gets cancelled by coming into contact with various acidic ingredients added in the food.
    However(for awareness), caustic soda, by itself is a corrosive strong alkali, and can create burning sensation and irritation like some acids. Many products we use are made using caustic soda as one of the ingredient. But because it has undergone chemical reaction during the process, we do not come into contact with casuistic soda as such in such products.

  • Purified salt has some iodine content mixed with it and it is good in certain condition otherwise normal uniodised salt is OK for consumption.
    Simply cleaning the sea salt for impurities may not make it harmful for health until unless some chemicals are intentionally mixed for improving its look and texture.
    I do not think that under stringent govt regulations it is possible to do such adulteration.

    Thoughts exchanged is knowledge gained.

  • Sea salt in its original cleaned form and salt from mountains is good for health as these contain various minerals and trace elements in small quantities which are good for health.

    On the other hand the processed salt or table salt which is now a days available in market is processed and during this loses those minerals. Over and above that to give it a white color it is bleached. This may be surprising but all these processings make it unfriendly to good health. This is the reason why intake of this salt is to be taken in minimal quantities. As iodine is also mixed in it so to that extent it takes care of iodine deficiency.

    Definitely salt from rocks and unprocessed sea salt are better health options than free flowing white table salt.

    Knowledge is power.

  • Your table salt is contains 97.5% sodium chloride and 2.5% chemicals such as moisture absorbents, and iodine etc. Table Salt is a manufactured from sodium chloride.Iodized salts that are available in markets have synthetic chemicals added to them. These chemicals include salts like sodium solo-co-aluminate, fluoride, anti-caking agents, toxic amounts of potassium iodide,sodium bicarbonate,iodide and aluminum derivatives. So table salt is unhealthy but it can be toxic also. Be careful in taking the salts and also read the instructions and effects of the salt before buying it.
