MENEZES, Bruna da Silva; CORTEZ-VEGA, William Renzo  e  PRENTICE, Carlos. Nanocomposites films obtained from protein isolates of mechanically deboned chicken meat added with montmorillonite. Polímeros [online]. 2017, vol.27, n.1, pp.75-82. ISSN 1678-5169.  http://dx.doi.org/10.1590/0104-1428.2253.

The aim of this study was to evaluate the properties of nanocomposite films of protein isolates from mechanically deboned chicken meat with organoclay (montmorillonite). For the film development, a 23 experimental design was performed with three levels, protein isolate (2, 3.5, 5 g.100 mL-1 of solution), montmorillonite (0.3, 0.5, 0.7 g.100mL-1 of solution) and glycerol (25, 30, 35 g.100 mL-1 CPI). The tensile strength varied between 6.7 and 9.1 MPa, elongation to break from 26-66%, opacity of 13.1 to 35.7 and solubility from 38.5% to 81.8%. Assessing the structural properties, interleaving of the isolate and montmorillonite can be noted. The results obtained in the experimental design indicate that 2.0 g of CPI.100 g-1 of solution, 0.8 g of MMT.100 g-1of solution and 0.2 g of glicerol.100 g-1CPI are the ideal parameters for preparing nanocomposite films.
