Plant-Based Protein Films and Coatings | SpringerLink
Due to the high cohesive energy density of dried protein matrices, neat protein films/coatings are brittle; the incorporation of compatible plasticizers is needed impart film flexibility essential for end-use handling (Kester and Fennema 1986). Typically, plasticizers are small molecular weight compounds added to modulate polypeptide chain
Plasticizers for Protein‐Based Materials
There are numerous reports on plasticized protein‐based films, including matrices from plants such as soy, pea, sunflower, and wheat proteins and zein [5]. Animal‐based protein matrices include sodium caseinate, keratin, gelatin, collagen, and whey and myofibrillar proteins.
Protein-Based Biological Materials: Molecular Design and
Polymeric materials produced from fossil fuels have been intimately linked to the development of industrial activities in the 20th century and, consequently, to the transformation of our way of living. While this has brought many benefits, the fabrication and disposal of these materials is bringing enormous sustainable challenges. Thus, materials that are produced in a more sustainable fashion
Protein-based materials: from sources to innovative
Proteins display an essential role in numerous natural systems due to their structural and biological properties. Given their unique properties, proteins have been thoroughly investigated in the last few decades, offering a myriad of solutions for the development of innovative biomaterials, including films,

- Are polyols a good plasticizer for protein based materials?
- Polyols are often cited as good plasticizers for protein based materials , , , due to their ability to reduce intermolecular hydrogen bonding while increasing intermolecular spacing. Then, the mechanical properties of caseinate films were studied versus plasticizer type and content in the film.
- Which polyol-type Plasticizers improve mechanical properties?
- Among the different polyol-type plasticizers tested, glycerol (Gly) and triethanolamine (TEA) were the most efficient for the improvement of mechanical properties (high strains for low stresses).
- What types of plasticizers are used in protein films?
- Common external plasticizers used in protein films are typically polyols, mono-, di-, and oligosaccharides, as well as fatty acids and phenolic acids . The selection of a plasticizer for a particular polymeric system depends on their compatibility with each other and the desired characteristics of the final product .
- Are glycerols a good plasticizer for protein based materials?
- Glycerols are often cited as good plasticizers for protein-based materials due to their ability to reduce intermolecular hydrogen bonding while increasing intermolecular spacing. As a small hydrophilic molecule which could be inserted between protein chains, it acts as a plasticizer.
- Do polar plasticizers increase hygroscopic properties of proteins?
- The application of polar plasticizers does increase the natural hygroscopic nature of proteins, and such produced materials will always be susceptible to moisture-dependent changes in mechanical as well as barrier properties. 4.1.2. Amphiphilic Plasticizers
- What is the aqueous mixture of protein and plasticizer?
- Aqueous mixture of protein (5% w/v) and plasticizer (plasticizer/protein ratios = 25%, 50% and 100% w/w, respectively) was magnetically stirred at 800 rpm for ∼12 h at room temperature in order to get a homogeneous solution.
