Transglutaminase is an enzyme of microbiological origin. As a biocatalyst it provides protein compounds through the cross connection between amino acids such as lysine and glutamine. As a result of protein bonding, functional and technological characteristics of proteins improve significantly. Transglutaminase increase moisture retaining capacity, gelling property, emulsifying and gel-forming ability, as well as moisture binding and thermostability. It has a positive impact on texture, consistency and taste of the product. Natural origin of transglutaminase makes ready-made products environmentally friendly. Using transglutaminase reduces cost of manufacturing, provides physical attractiveness and improves organoleptic qualities of products, increases shelf life and improves properties that cause positive effect on people’s health. Moreover, transglutaminase decreases caloric content of products, reduces (or even eliminates) stabilized supplements, increases the output of ready-made products. It also easily adapts to technological process.
