(more than 90 % purity)
Dear Ayman
Attaching here article on optimization process for extraction and purification of Bixin. I hope you will get enough information by this article.
best of luck and happy new year.

Dear Dr Ajay
Thanks a lot for your kind cooperation. Also, I found another article" PRESSURIZED LIQUID EXTRACTION (PLE) OF BIXIN FROM DEFATTED ANNATTO SEEDS"
III Iberoamerican Conference on Supercritical Fluids
Cartagena de Indias (Colombia), 2013
Happy new year, wishing you a very good luck
Ayman AL-Zahry
Yes. it is nice article. Thank you very much.
There is another article"PRESSURIZED WATER EXTRACTION (PWE) OF ANNATTO PIGMENT"
The method described in both articles is worth to get desired annatto pigment.
Can NOTHINGNESS be made of particles ??
