Herbs remain a target for fraudsters. The latest investigation of sage samples by the Institute of Global Food Security (IGFS) at Queen’s University Belfast used a combination of spectroscopic and chemometric methods to check whether sage contained 100% of the actual herb. One quarter of samples from the UK included unapproved (fortunately, no hazardous) bulk material, such as tree leaves, some in significant concentrations of more than half of the product.
