The strong chemical compound can be used in two ways, as a technical auxiliary material or as as the additive E 513, which is harmless to health. In the first case, the use of sulfuric acid does not need to be indicated. In the second case, it must be stated in the list of additives.
Before sulfuric acid can be used in the food industry, either as a technical auxiliary material or as the additive E 513, it has to overcome major barriers. Its food-grade quality must be fully and traceably documented and presented to the supervisory authorities. To fully meet these criteria, the LANXESS group, which has produced sulfuric acid for more than 100 years, uses a state-of-the-art plant.
