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.

The most commonly used plasticizer for protein films is glycerol, which is miscible in most proteins, but several other plasticizers have also been studied [ 7 – 12 ]. Examples are polyfunctional alcohols such as sorbitol, propylene glycol, and di‐ and triethanolamine [ 1, 4, 7, 8, 10, 11, 13 – 20 ].

Hedenqvist Published 21 September 2016 Materials Science This study presents a practical approach to select plasticizers for proteins. It is a case study on thermoformed wheat gluten, considered here as a model protein, and it involved 30 plasticizer candidates.
The Latest Supply Chain Disruption: Plastics
Most supply chain practitioners would agree: between the pandemic, container shortages, winter weather, factory fires, the blocking of the Suez Canal by a container ship, and other logistics woes
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,
- What is a plasticizer in chemistry?
- The council of the IUPAC (International Union of Pure and Applied Chemistry) defined a plasticizer as “a substance or material incorporated in a material (usually a plastic or elastomer) to increase its flexibility, workability, or distensibility”.
- Which biological materials contain a high volume fraction of proteins?
- While these structures are the most abundant and studied proteinaceous materials, there also exist “bulk” biological materials containing a high volume fraction of proteins and that are subjected to compressive or shearing mechanical loading regimes, notably exoskeletons and mouthparts.
- What are natural based plasticizers?
- Nowadays, there is increasing interest in the use of natural-based plasticizers that are characterized by low toxicity and low migration. This group includes epoxidized triglyceride vegetable oils from soybean oil, linseed oil, castor-oil, sunflower oil, and fatty acid esters (FAEs) .
- Which compounds are used in plasticizers for sunflower protein isolate films?
- The use of five compounds (GLY, EG, DEG, TEG and PG) as plasticizers for sunflower protein isolate films, producing soft, brown and smooth films, with good mechanical properties and a high level of impermeability to water vapor .
- Why are plasticizers important in biopolymer-based films & coatings production?
- In biopolymer-based films and coatings production, plasticizers are also essential additives since they can improve flexibility and handling of films, maintain integrity and avoid pores and cracks in the polymeric matrix .
- Can bio-based plasticizers replace conventional plastic goods?
- The challenge to implement this new class of natural-based plasticizers matches the increasing interest of material researchers and industries in new bio-based materials, made from renewable resources with the potential, not to totally replace but to reduce the use of conventional plastic goods.
