Detection of Boric Acid as Food Preservative in Food

[Louise77]

The use of Boric Acid as preservative in food has since been banned.
Recently, the case of boric acid usage as food preservative has surfaced again.

Does anyone has the method of detection of Boric Acid in food to share? What mobile phase should I use? Can I use a C18 column or which column should I use?

Boric acid in various types of matrices (e.g., cornflakes, dried fruit, aqueous soln's, etc...) can be reliably detected and quantified using "volumetric titration" be sure to include a reagent blank in your assay. There's no need to use or develop an LC method for this analyte.
