  • Yes turmeric may be adulterated. The main adulterant used are colours and fillers like saw dust, rice flour, starch. These adulterant may be harmful and even cause cancer in our body. These adulterant many affect your nervous system.

    Identification of turmeric powder
    Take powder and add HCl, if pink colour appears and does not go away after sometimes it means here is adulteration of colour. If it does go away after sometimes it means , no colour is added.

    Honesty is the best policy.

  • Anything gets adulterated these days. Videoclips are coming in WhatsApp and YouTube showing how essential food items get adulterated easily and how we the innocent and undoubting people buy and consume them falling victims to the dirty tricks played by self seeking people.

    There are the harmless adulterating ingredients like starch powder, cheap and less quality rice powder,cheap quality turmeric, the roots and fibres of the plant not generally used for food, or similar tubers, and the non-food varieties. These serve as filers just enhancing quantity saving cost and earning profit.

    However the harmful chemical adulterants like the yellow dyes and colours are also found used widely. The chemicals used thus include metanil yellow, Lead chromate etc.
    There were periodic reports in the news media in Kerala about a very popular manufacturer of kitchen masalas caught for adulteration. All the times he remitted the fine(in lakhs of rupees) and continued to do so. The adulterated items included turmeric powder also.
    While the harmless filers get noticed by the housewives who know the general texture, colour and smell of genuine turmeric powder, it is not so easy to identify chemical alteration. For the ordinary users it is better to stick to the established local vendors or go for the reputed established brands.

  • Yes, Tutmeric can be adulterated inspite of tall claim of the purities claimed by the manufacturers. The contaminants are rice - flour, saw- dust, starch, chalk, lead chromate, metanil yellow etc . The immediate - effects of such adulteration is not noticeable but in the long can cause liver and kidney disorder, skin - disease and even can cause nervous breakdown.
    There are certain chemical tests for the identification of the impurities. In order to identify the contaminants, take a small quantity of Turmeric - powder in a test tube by properly dissolving it in water. Now, a few drops of concentrated sulphuric or hydrochloride acid has to be added in the test - tube. you may notice the development of pink - colour after some time. If the pink colour persists even after ten minutes. You can safely conclude that the powder is mixed with the impurities. But if the colour vanishes, it would indicate the purity of the substance.
    In order to detect the presence of chalk in the sample, take a pinch of the sample dissolved in water in a test- tube, add a few drops of either sulphuric or hydrochloric acid, if effervescence takes place, we can say that sample is contaminated with chalk.

  • There are mainly two ways in which turmeric powder is adulterated - first is by adding some fillers like saw dust, starch, chalk powder, yellow soapstone or rice flour etc. Second is color dyes like metanil yellow or lead chromate.

    Adulterated turmeric is harmful for health and can affect nervous system and also lead to cancer.

    For chalk powder adulteration sprinkling a pinch of turmeric in a
    clear glass filled with warm water will give an idea. If turmeric settles down and water is clean then there is no adulteration but if water is cloudy it means that chalk powder is mixed.

    For starch adulteration microscope is used to distinguish the bigger, angular and yellow turmeric particles from smaller colorless particles of starch.

    For metanil yellow color adulteration test with concentrated hydrochloric acid is done and if it gives a continuous pink color it confirms adulteration.

    For lead chromate adulteration the test is a bit long. First tumeric is burnt to ash and then sulphuric acid is mixed. This is filtered and 0.1% strength solution of dipenylecarbazide is added to filtrate. A pink color indicates lead chromate adulteration.

    Experience people can differentiate the adulterated turmeric by looking, rubbing, smelling and tasting.

    Anyway we should avoid purchasing turmeric in loose and go for branded and certified food products labels on the packets.

    Knowledge is power.

  • Yes Now a days we are getting adulterated turmeric powder in the market and it is our duty to ensure that we buy the genuine produce as turmeric powder is used for cooking and also for bathing purpose. Normally there are two kinds of turmeric. One is wet and other one is dry. The wet turmeric is natural and it is generally preferred by ladies for Pooja purpose and they also wear the same in their Mangalsutra as the mark of purity. The dry turmeric is pounded and sold in varied grams. It is better to go for branded varieties as there wont be any chance for adulteration. The best way to find whether the turmeric is pure or not is to smell for the same. When it smells like turmeric then it is real. Otherwise some chemicals are added to make the content.

  • We are living in the world of artificial plastic egg and cabbage. Food adulteration is increasing, turmeric is one of the most common spice with excellent medicinal qualities but it is adulterated by adding metanil yellow or lead chromate which are highly carcinogenic.

    To test the quality of certain of turmeric, add 1 spoon of turmeric powder in twenty ml of water. Add a 1ml of hydrochloric acid or any common acid with it. If the water turns pink, violet or purple, it shows that the turmeric is adulterated.

    If you have the fear of turmeric adulteration, Just get whole dried raw turmeric, dry it completely in the direct sunlight and make powder.


  • Hi Avi,
    Yes, turmeric can be adulterated. The manufactures of the spices claims that their spices are pure enough but it is fake as they adulterate it to increase their profits. Turmeric can be adulterated with corn starch, chalk dust, metanil yellow or lead chromate and even if with normal flour.
    If you repeatedly consume adulterated turmeric powder it can cause long term disease like cancer in your digestive system, skin problem and different types of physical disorder.
    To detect it is pure or not, smell the powder closely. Turmeric has a very specific sharp smell. If you do not detect it use concentrated HCL. mix turmeric powder in concentrated HCL, it will turn into pink colored solution. If the color go after a little bit of time then we can say that it is pure or not adulterated. If the color remains same then the turmeric powder is adulterated.

  • Yes turmeric will have lot of adulterant. Even yellow color can also be added. To identify pure turmeric we can always find out by the smell.
    1) It has a beautiful smell of turmeric plant.
    2) A pinch of turmeric and add little Luke warm water if it turns red then it has adulterant and not original turmeric.
    3) Pure turmeric should immediately dissolve and give yellow color.
