“…Studies by Kowalczyk et al 21 demonstrated similar behaviors when using films of soy protein and candelilla wax. The ΔE of the biofilms grew with the increase of the wax concentration; similar results were also obtained by Monedero et al 17 when they incorporated beeswax into soy protein. Table 2 shows the influence of the carnauba wax concentration on chitosan films WVP and thickness.…”

Films and edible coatings of natural polymers have been proposed as an attractive alternative for conventional plastic packaging because of their excellent biodegradability and biocompatibility. However, natural polymers, like chitosan, are hydrophilic and present poor water barrier properties. The addition of wax or other hydrophobic substances decreases water permeability of natural polymers but can increases their opacity.The objective of this work was to produce biofilms based on chitosan and different concentrations of carnauba wax and analyze their optical and barrier properties. The films were obtained by dissolving chitosan in acetic acid. Carnauba wax was incorporated into filmforming solutions at0, 15, 30, 40 and 50% (w/w). The opacity increased with higher concentrations of wax, the film with 50% of wax showed the highest value with an increase of 10.5% compared to the control film. The water vapor permeability decreased from 2.73 g.mm/kPa.m 2 .h (0% of wax) to 0.77 g.mm/h.kPa.m 2 (40% of wax). The solubility decreased to about 60% over the control films, and the contact angle increased from 53º to 83º, in film with 0 and 50% of wax, respectively.

“…Hasil ini serupa dengan dengan penelitian Muscat et al (2013) yang menyatakan bahwa penambahan 5 % beeswax ke dalam pati tinggi amilosa dapat menurunkan kuat tarik dari 31.6 menjadi 25.8 MPa sedangkan elongasi meningkat dari 4.3 menjadi 9.2 %. Menurut Monedero et al (2009) komponen beeswax mampu meningkatkan derajat diskontinuitas matriks polimer sehingga perubahan bentuk film dapat diminimalkan. Semakin rendah kuat tarik film, fleksibilitas film semakin meningkat.…”

“…However, as a consequence of their high hydrophilic character, soy protein fi lms show low barrier properties to moisture. Two main strategies are considered to overcome this drawback: a) mixture with hydrophobic compounds such as lipids [51], and b) modifi cation of the protein network arrangement through crosslinking of the protein chains by using physical, enzymatic or chemical treatments [52]. For example, agar-based fi lms with soy proteins and glycerol as plasticizer were successfully processed by increasing their processing time.…”

In this study we provide an overview of the latest developments on the extraction, production, modifi cation and applications of fruit residues and by-products in the formation of protein-based biopolymers, in particular for the formulation of edible fi lms. Our aim was mainly to demonstrate the highly transdisciplinary character of these topics by giving an overview of the main developments and research topics in the chemistry and engineering aspects of protein-based biopolymers. These innovative raw materials have been evaluated for the production of biomaterials to be used in some key sectors, such as food packaging.
