WebbPlants have been recognized as renewable and sustainable sources of proteins. However, plant protein extraction is challenged by the plant’s recalcitrant cell wall. The conventional extraction methods make use of non-reusable strong alkali chemicals in protein-denaturing extraction conditions. In this study, soy protein was extracted using … WebbAmmonium salts are ionic compounds with the formula (R) 4 N + A –, where R represents hydrogen, alkyl, or aryl group and A represents an anion. When R is alkyl or aryl, the salts are known as quaternary ammonium salts. The quaternary ammonium cations are permanently charged, regardless of solution pH. scotiabank waterdown hours
