Heat-induced gels in threedimensional
network are formed in an ordered fashion and
exhibit smooth texture when unfolded proteins are associated in
slow heating fashion (i.e., setting). However, when aggregation is
done rapidly, gel matrixes tend to be rough and coarse
(Hermansson, 1979). Consequently, a more compact and denser gel
network was developed after setting. With addition of 1 g NFB/
100 g paste and setting, gel’s microstructure appeared definitely
smoother and denser (Fig. 3b NFB) due to the formation of 3-(gglutamyl)
lysine covalent bonds enhanced by TGase and NFB
calcium.
