Development of an accurate and direct method for the green food colorants detection.
Pérez-Gálvez A, Viera I, Roca M. Pérez-Gálvez A, et al. Food Res Int. 2020 Oct;136:109484. doi: 10.1016/j.foodres.2020.109484. Epub 2020 Jun 26. Food Res Int. 2020. PMID: 32846566
Native chlorophylls do not chelate copper. Therefore, we propose a fast and specific method for copper chlorophyll detection, as indicative (except in a few fermented foods) of probable green food colorant addition or "re-greening" with copper s …
