“…Therefore, biopolymer-based edible films or coatings, including polysaccharides, proteins and lipids due to their biodegradability are considered to be a promising solution to those made from synthetic polymers [1][2][3]. However, biopolymer films are limited in their capacity to achieve wide commercial usage due to weaknesses related to performance, such as poor moisture barrier and mechanical properties [4].…”

“…PPI‐X films with 25% glycerol showed higher TS (10.7 MPa) than those of some plant protein films including soya (SPI) (Tang et al ., ), faba bean (FPI) (Saremnezhad et al ., ), pumpkin (PuPI) (Popović et al ., ), bitter vetch (BPC) (Arabestani et al ., ) and sunflower (SPC) (Salgado et al ., ) as former studies reported. E value of PPI‐X films was in the range of those of other plant protein films as reported.…”

Summary This work aimed at producing and characterising xylose‐glycosylated peanut protein isolate (PPI‐X) films by dissolving PPI‐X powder in water at ambient temperature and further plasticising with glycerol. The effect of powder dissolution temperature (20–100 °C) and glycerol concentration (15.0–45.0%, w/w) on mechanical properties and integrity of these films was quantified. The results showed that the powder dissolution temperature had no significant effect on the mechanical and water resistance properties of PPI‐X films within the temperature range tested. With increasing concentration of glycerol, the tensile strength and water resistance of PPI‐X films decreased and elongation increased. The films produced by dissolving the PPI‐X powder at 20 °C and plasticising with 25.0% glycerol had comparable mechanical properties and better water resistance compared to some other plant protein films plasticising with glycerol. The results suggested that PPI‐X films could potentially be used as biodegradable packaging materials.

“…To this aim, protein concentrate, obtained from bitter vetch ( Vicia ervilia ; BV) seeds and recently proposed as a promising source for both edible films and biodegradable containers [22,23,24], was used as raw material of protein-based film forming solution. BV is an ancient grain legume crop, originated in the Mediterranean region, which can be found today in many countries around the world.…”

Zeta potential and nanoparticle size were determined on film forming solutions of native and heat-denatured proteins of bitter vetch as a function of pH and of different concentrations of the polyamines spermidine and spermine, both in the absence and presence of the plasticizer glycerol. Our results showed that both polyamines decreased the negative zeta potential of all samples under pH 8.0 as a consequence of their ionic interaction with proteins. At the same time, they enhanced the dimension of nanoparticles under pH 8.0 as a result of macromolecular aggregations. By using native protein solutions, handleable films were obtained only from samples containing either a minimum of 33 mM glycerol or 4 mM spermidine, or both compounds together at lower glycerol concentrations. However, 2 mM spermidine was sufficient to obtain handleable film by using heat-treated samples without glycerol. Conversely, brittle materials were obtained by spermine alone, thus indicating that only spermidine was able to act as an ionic plasticizer. Lastly, both polyamines, mainly spermine, were found able to act as “glycerol-like” plasticizers at concentrations higher than 5 mM under experimental conditions at which their amino groups are undissociated. Our findings open new perspectives in obtaining protein-based films by using aliphatic polycations as components.
