Microbial transglutaminase (MTGase) is an enzyme of the class of transferases widely known to modify protein functional properties in food systems. The main mechanisms of action involved are polymerisations, which result in changes in the molecule’s hydrophobicity. Among the functional properties, MTGase affects solubility and hence gelation, emulsification, foaming, viscosity and water-holding capacity, which all depend on protein solubility. Although the enzyme’s benefits for protein functionality in a variety of food systems are widely reported in the literature, few studies have focussed on its mechanisms. The purpose of this review is therefore to investigate the mechanisms of action of MTGase and consider its influence on the functional properties with different protein substrates. Understanding these mechanisms is the first step in the development and application, in food production, of new and better functional properties with improved and/or innovative characteristics that can satisfy consumer expectations.
