Regarding the article Carré P, Piofczyk T, Bothe S. 2025. Solvent Solutions: Comparing Extraction Methods for Edible Oils and Proteins in a Changing Regulatory Landscape. Part 7: Overall comparison between solvent solutions. OCL 32: 9., published on April 23, 2025, a transcription error regarding the lethal dose of n-hexane in rats has led us to publish the following correction:

Aggregation of criteria related to product quality

The consequence is a slight evolution of the n-hexane ranking for the score of this solvent in the seventh criteria about impacts on products quality and acceptance, the score passing from 3.0 to 3.3 with little consequences on the global appreciation of normal hexane.
