Wheat gluten films obtained by compression molding
Pommet et [6] prepared wheat gluten blends with 5 different plasticizers (water, glycerol, 1,4-butanediol, octanoic acid and lactic acid) in a mixing chamber at 80 and 60 °C, for hydrated and dry gluten, respectively, and then the blends were compression-molded at 100 or 130 °C.
New plasticizers for wheat gluten films - ScienceDirect
Wheat gluten films were prepared with glycerol, diethanolamine or triethanolamine as the plasticizing agent. The influence of these substances on the gluten film properties were studied at two RH conditions (58% and 98%) and for two amounts of plasticizer (10 g and 20 g/100 g dm). 3.2.1.
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.

Conventionally, glycerol has been used as plasticizer for gluten, but several new plasticizers have also been reported to provide better stability and mechanical properties. 12 It was shown...
Tannic acid: A green crosslinker for biopolymer-based food packaging films
The film's stiffness was enhanced as well as the water vapor barrier properties. Also, the films were more resistant, less resilient, and flexible due to the crosslinking of tannic acid with wheat gluten. The effect of condensed vs. hydrolyzable tannins on the gluten-based film was also investigated by Girard, Teferra, and Awika (2025).
- What are wheat gluten based coatings & films?
- Wheat gluten–based coatings and films are primarily produced through solvent casting, compression, molding, extrusion, and electrospinning. The coatings and films are highly resistant to oxygen and thus possess good oxygen barrier properties.
- Can glycerol monolaurate be added to wheat gluten based film?
- Zhang et al. (2020) incorporated glycerol monolaurate into wheat gluten–based film through electrospinning and found that the addition improved the film's water stability and antimicrobial activity against Staphylococcus aureus and Escherichia coli.
- What is the optimal formulation for wheat gluten-based films with cellulose nanofiller?
- The optimal formulation for wheat gluten–based films with cellulose nanofiller (CNF) and carboxymethyl cellulose (CMC) was also determined: Overall, 1% wheat gluten, 0.686% CMC, and 8.549% CNF resulted in desirable water vapor permeability and mechanical properties (Bagheri et al., 2019).
- Does humidity affect glycerol-plasticized wheat gluten film tensile strength?
- Kayserilioǧlu et al. (2003) reported that at 35% relative humidity (RH), the increase of drying temperature from 20 to 80°C improved the tensile strength of glycerol-plasticized wheat gluten film, whereas at 70% RH, the increase of drying temperature from 20 to 80°C reduced the film's tensile strength.
- Can Plasticizers improve film flexibility?
- Plasticizers, such as glycerol, sorbitol, diethanolamine, and triethanolamine, can also be added to improve film flexibility, although the addition of plasticizers decreased film's tensile strength and water vapor permeability (Gontard et al., 1993; Irissin-Mangata et al., 2001; Zubeldía et al., 2015). TABLE 1.
- Does wheat gluten based film affect the quality of refrigerated strawberries?
- The antimicrobial effect of wheat gluten–based film on the quality of packaged foodstuffs has also been reported. Tanada-Palmu & Grosso (2005) investigated the effect of bilayer biocomposites of wheat gluten and lipids (beeswax and static and palmitic acids) on the quality of refrigerated strawberries.
