L4. Why Raw Turmeric is Boiled: An Experiment in Lab 

I apologize for the delay in response. Curcumin and volatile oil both are lost while boiling to some extent. This was practically observed by me after testing. Thanks and regards

Boild at 45mins. 😮

Thank you very much

Black turmeric is from a different species Curcuma caesia whereas normal turmeric is from Curcuma longa. Black turmeric is probably more used for some specific medicinal purposes. I did not so far analyse black turmeric and hence no idea as to how to use. Thanks and regards

@@sciencesmilesshorts ok thank you for your reply

For cooking boiling is recommended as it gives a good appearance. Perhaps for cosmetic purposes turmeric without boiling (directly dried) may be helpful, as heat sensitive natural constituents are retained. Thanks and regards

Many thanks for your interesting question. Boiling is done by two methods in turmeric field. 1. boiling in water 2. By steam. The objective is to ensure that the curcumin gets distributed into the finger uniformly by gelatinization of the surrounding starch in turmeric finger. in water boiling method they boil for 40 minutes the completion of boiling is indicated by froth on the surface. In steam boiling they boil for about an hour. Ultimately the best judgment is by breaking one finger which should be soft and the color should be uniform. I shall produce more short videos against all questions in future. regards

@@sciencesmilesshorts Thank you so much for replying to my query. It is very helpful.

It is yet to be dried till it becomes non sticky and nearly becomes brittle. Two days may not be sufficient, depending on your climate. It is normal to be sticky with high moisture because of the starchy substance. Thanks a lot for your interest and best wishes

@@sciencesmilesshorts thank you so much!!

You can dry in low heat with gas in a pot... quality won't reduce and get dried

Hi, Thanks for the message. I apologize for the delay in response. Turmeric may contain heavy metals depending on the source, soil and post harvest practices. Lead is a contaminant mostly arising from some post harvest practices of boiling in some vessels which may contribute and partly depending on soil salts. Turmeric from many parts and sources does not contain lead or heavy metals in unacceptable levels. This can be ascertained by testing with AAS. Thank you

Many thanks for your message. I think you are speaking of dried turmeric. whatever, curcumin is almost insoluble in water. There can be very little dissolution due to pH range. So there is no point in taking turmeric soaked water for the benefits of curcumin. The oil floating is the essential oil of turmeric which contains lot of antioxidants. To get the benefits of both curcuminoids and essential oil we add in curries and even some make a special curry with fresh tumeric. Some add a pinch of turmeric powder in milk so that milk fat extracts the curcumin and others. Some add in ghee as well. I shall come out with the benefits of turmeric in a separate video. Thanks and regards

@@sciencesmilesshorts hi...I'm adding a piece of turmeric to boiling water. Is that a good idea..?

Not much of use. The essential components are almost insoluble in water (very little). Better to add a pinch of turmeric powder to a glass of milk. Thanks again.

@@sciencesmilesshorts thank you..

After boiling if skin is removed and air dried fungus will fast attack the surface.The practice is after boiling it is dried with skin and then polished. Nutrients are lost by leeching along with a little of curcumin (little as it is not quite soluble in water). Some curcumin is lost/degraded due to heat. The alternative is steam boiling, here some nutritive values are lost because of high temperature and also curcumin. I developed an alternate method apart from the above for small quantities.

@@sciencesmilesshorts thank u..but how we polish for grinding turmuric for home
