In Fig. 2, images of cross-linked and noncross-linked labneh samples showing the macroscopic changes in the product structure were given. As seen in Fig. 2 noticeable
changes in macrostructure, including gel firmness and fluidity of the labneh samples, occurred for 2 U and 4 U (Fig. 2(d) and (e)).The impact of TGase on gel strength is consistent with previous studies
