Konjac root powder
My order of 20oz of this stuff just arrived from Thailand. It is a light-brown powder. I tried adding about a quarter teaspoon to a glass of water to see what happens. After ten minutes it is still a mass of particles, stirred, it looks like dirty water. This is normal?

It behaves like a gum … your best bet is to homogenize it. -
I’ll try in a little while when I get back to the lab, but at an hour and a half it is still the same, no change.
-
I blended it for several minutes and it still looks like pond water with a sediment
-
Added a lot more powder. Now it looks like really muddy water. There is NO evidence of any kind of gel. No thickening whatsoever. And this would not make a product… except if you want a mud pack. I think I’ve wasted my money.
-
I have a sample I got a few weeks ago but haven’t had time to have my chemist play with it yet. I think they are not all the same though. You may need to get from a specific source to get the gel your looking for but I am not certain.

I can’t even see this working as a diet aid. It says 100% konjac root powder on the packaging. It’s muddy, gritty. It reminds me of henna or turmeric.
-
Did you try to heat it while mixing? Maybe its worth a try.
BTW: where did you source your konjac gum? I would like to try it at our lab. -
What you are describing … muddy, gritty .. similar to henna … is not Konjac Root Powder.Konjac Root Powder is a pale beige color, similar to Xanthan Gum, and forms a clear gel when used at 1%. At percentages less than 0.5% if thickens, but does not gel.
-
Dog knows what they have sent me (from Thailand). I will take it up with the supplier. I tried heating it and it made no difference. It’s just as if I took some fine dry soil from the garden and mixed it with water. How disappointing.
-
First, get a water content from a couple of grams, then see if it’s flammable. That way, you’ll at least have some ammunition when you talk to the supplier.
-
Perhaps something like this would be a better choice for experimenting with Konjac?
-
Bob, you’re quite right. There is, it seems, some abiguity about what konjac root powder is. The stuff in that Amazon supplier’s bottle is krp extract. What I bought was, apparently, actual dried konjac root powder, not the extract. As to if it has any use at all, I have no idea. Make it into a face mask perhaps … (grin)

The sample I have is called Konjac Mannan Gel Powder. It is off white in color. I have not tried it yet. Comes from a supplier named Kinetik in New Jersey.
The manufacturer is GFN http://www.gfn-selco.de They are in Germany
-
The one I have is off-white in colour and creates a gel IMMEDIATELY its in contact with water.
What they supplied you is not the real thing. -
@belassi, if you really have powdered roots, maybe you need to find out how the Glucomannan is extracted from the root?
-
The konjac I have is an off white powder which gels very quickly and a 1% solution is slightly cloudy and viscous. If you’d like my supplier’s details please do PM me.

I think I have enough problems right now with imports. A sample from the USA is held up (DHL) while the supplier (a really big company) tries to clear it, and I also had to return $400 worth of licorice to China. I’m going to forget about this.

I have used the Now Foods powder Bobz refers to and it does indeed form a gel, different in texture than both xanthan and carbomer though, more “stringy”.
-
I made a gel using 1% Konjac Root Powder using room temperature distilled water. I noticed that the gel is unstable as it liquefy in 48 hours at room temperature. I must try adding xanthan gum and heating it to 90C. The only problem is when I apply this gel on the skin, it rolls/rubs off the skin. How do I fixed this? Should I use less and use other thickeners? I want to make a thick gel that includes Konjac Root Powder.
