Glycyrrhizin Concentration Testing

Recommended Posts

I recently submitted a formula to the TTB that came back for edits because of our inclusion of licorice root. Their statement reads as follows:

"Glycyrrhizin is found in licorice. Per 21 CFR 184.1408, the limit for glycyrrhizin in an alcoholic beverage is 0.1%. Please verify the percentage of glycyrrhizin present in the final product is less than or equal to 0.1%."

Is anyone familiar with outfits that can perform testing on our finished product? Or is a mathematical proof required assuming an initial concentration of Glycyrrhizin in our licorice root is within the range of 2-15% of the dry product per "Natural Food Additives, Ingredients & Flavourings" (Fry, 2012).

Also, does anyone have any supporting documentation from the FDA that can be used to support the use of Hawthorn berries in an alcoholic beverage?

Thanks!

We used this company. They needed finished product and raw material (licorice root).

I would just assume the highest concentration of glycyrrhizin in the root and then do some quick math to see how close you are to 1% glycyrrhizin in your product...

If it is indeed 50x the sweetness of sucrose, you shouldn't even approach 1% glycyrrhizin unless you're making an alcoholic simple syrup.
