Is this article credible? It seems against common sense, and I’d never seen it cited before.
https://www.jidonline.org/article/S0022-202X(15)49627-7/pdfAlthough practices like superfat with fatty acid or bring down pH directly with acid or leaving part of the fatty acids unneutralized aren’t really backed up by science.
Sorry, there were no replies found.
