How to dilute Capsaicin?
We get asked how to dilute Capsaicin quite often. Capsaicin’s greatest challenges in using this chemical compound is its low solubility in water and storage instability. Therefore, while a pure water solvent system would be ideal for such solutions requiring human consumption, tap water alone cannot be used since the capsaicin does not dissolve in sufficient quantities to afford meaningful testing. Most studies have found that using a solution of capsaicin mixed in water will get you a low concentrations of organic solvents. On a positive not capsaicin has been shown to be completely soluble in organic solvents, with ethanol (EtOH) providing the greatest solubility.
Capsaicin is soluble in cold water but not recommended. (Distilled water if you have to use water) A method of solubilizing capsaicin in water by intermediary solution in ethanol is described here. A nice discussion of solubility and taste effects of various molecules including capsaicin can be found here. Ethanol or oil are recommended solvents. Calcium efflux from your cells makes the burning taste.
How do you get a 1 million Shu solution from 16 million shu of capsaicin powder?
Answer :
Option 1: To get from 16,000,000 shu to 1,000,000 shu you need mix 15 parts of ethanol with 1 part capsaicin powder (16million shu ). That would be giving you a 1 million shu solution..
Option 2: Dilute 1 part of the capsaicin with 15 parts of grape seed oil. That will give the required dilution in a usable form.
