Cover Story: The effect of cross-linking with transglutaminase (TG) of two varieties of quinoa protein isolate (Chenopodium quinoa) [Willd (QW), and Pasankalla (QP)] on the physicochemical and barrier properties of edible films based on chitosan (CT)-quinoa protein were evaluated. TG interacted with lysine of QW and QP reducing the range of water vapor permeability of the different CT:quinoa protein films to 2.42–4.69 × 10−11 g cm Pa−1 cm−2 s−1, and also the CT:QP (1:10, w/w) film showed reduced surface roughness to 4.4 ± 0.3 nm. From the sorption isotherm addition of TG to CT-QW films improved their stability [monolayer (Xm) = 0.13 ± 0.02 %]. Films with a higher amount of cross-linking showed the highest improvement in the evaluated physical properties, but interactions among proteins that were catalyzed by TG depended on the protein source and profile.
