“…The WPI particles [Figure (b)] were spherical, with smooth surfaces and average size from 10 to 50 μm. The morphological characteristics of WPI are usually attributed to the primary component, β‐lactoglobulin, characterized by wide spherical particles . Particles of sodium MMT clay showed irregular particles with average size of 5 and 50 μm [Figure (c)].…”

Active substances are added to polymers to act as a barrier to external elements, protecting the product. This article evaluated the effect of the addition of sodium montmorillonite (MMT) nanoparticles and the antioxidant activity of rosemary essential oil (EO) in thermoplastic starch/whey protein isolate (TPS/WPI) nanocomposites obtained by extrusion. X‐ray diffractograms showed dispersion/exfoliation of the MMT in the TPS/WPI matrix. The nanocomposites presented rough surface with the presence of porosity as shown by scanning electron microscopy images. Thermogravimetric analysis revealed that the combination between MMT and rosemary EO increased thermal stability of nanocomposites. The addition of rosemary EO became the films less rigid, weaker and had an antioxidant effect as shown by mechanical properties and 2,2‐diphenyl‐1‐picrylhydrazyl assay. The optical properties showed in opaque greenish yellow nanocomposites. Therefore, the addition of rosemary EO in nanocomposites showed an alternative for use as antioxidant polymers in packaging material. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.

“…These proteins are often agglomerated due to hydrophobic intermolecular interactions, disulfide bonds, hydrogen bonds and/or electrostatic interactions depending on the applied conditions, such as temperature, pressure, concentration and pH. Usually, WPI morphology is attributed to the presence of the principal compound, ␤-lactoglobulin (Ghosh, Ali, Selvanesan & Dias, 2010;Havea, Singh & Creamer, 2001).…”

The aim of this study was to evaluate the effect of replacing corn starch by whey protein isolated (WPI) in biodegradable polymer blends developed by extrusion. X-ray diffraction showed the presence of a Vh-type crystalline arrangement. The films were homogeneous, indicating strong interfacial adhesion between the protein and the thermoplastic starch matrix (TPS) as observed in scanning electron microscopy. The addition of WPI on TPS matrix promoted an increase in the thermal stability of the materials. It was observed 58.5% decrease in the water vapor permeability. The effect of corn starch substitution by WPI on mechanical properties resulted in a more resistant and less flexible film when compared the TPS film. The addition of WPI caused greenish yellow color and less transparent films. The substitution of corn starch by WPI made it possible to obtain polymer blends with improved properties and represents an innovation for application as a packaging material.

“…The insertion of soy protein isolate in the formulations was done with the aim of balancing the C/N ratio of the blend, which plays a key role in the biodegradation process of these materials. Gosh et al [108] employed whey protein isolate or WPI (highly aggregated) and its component lactalbumin (less aggregated) melt blended with PCL. The effects of structural morphologies of the proteins on the mechanical, morphological and in vitro enzymatic degradation were examined.…”

State of the Art in the Development and Properties of Protein-Based Films and Coatings and Their Applicability to Cellulose Based Products: An Extensive Review

Abstract:There is increasing research towards the substitution of petrochemicals by sustainable components. Biopolymers such as proteins, polysaccharides, and lipids derive from a variety of crop sources and most promisingly from waste streams generated during their processing by the agro food industry. Among those, proteins of different types such as whey, casein, gelatin, wheat gluten, soy protein or zein present a potential beyond the food and feed industry for the application in packaging. The general protein hydrophilicity promotes a good compatibility to polar surfaces, such as paper, and a good barrier to apolar gases, such as oxygen and carbon dioxide. The present review deals with the development of protein-based coatings and films. It includes relevant discussion for application in paper or board products, as well as an outlook on its future industrial potential. Proteins with suitable functionalities as food packaging materials are described as well as the different technologies for processing the coatings and the current state of the art about the coating formulations for selectively modulating barrier, mechanical, surface and end of life properties. Some insights onto regulations about packaging use, end of life and perspectives of such natural coating for decreasing the environmental impact of packages are given.
