Description
Agnieszka Kowaluk and co-authors describe a 2026 green chemistry method for preparing gingerbread samples before mineral testing. Their solvent mixes choline chloride with lactic acid, forming a natural deep eutectic solvent that replaces harsh acids. Ultrasound helps the solvent pull elements out of the baked goods.
Three solvent ratios were made and checked with spectroscopic and heat-based methods. A structured experimental design tuned the solvent ratio, water content, and sonication time. Under the best settings, results for zinc, copper, and iron matched the design predictions. A decision tree model confirmed the same optimum. The authors present the approach as a promising, lower-impact route for food element analysis.
