Wheat gluten films obtained by compression molding
3.1. Effect of the processing conditions. The processing conditions for obtaining wheat gluten films by intensive mixing followed by compression molding were selected by comparing the final mechanical and physical properties of film produced with 25 wt% glycerol. Contrary to thermoplastic polymers, gluten viscosity does not decrease on heating
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. Opacity
Edible Polymers: Challenges and Opportunities - Hindawi
The cohesiveness and elasticity of the gluten give reliability to wheat dough and expedites film formation. The poor resistance of wheat gluten films to water vapor (Tables 1 and 2) was due to the hydrophilic nature of the protein and the substantial amount of hydrophilic plasticizer added to impart acceptable film flexibility. The properties
Plasticizers for Protein‐Based Materials
Blending procedure About 350 g wheat gluten powder and 150 g of plasticizer were blended using a food processor (WATT; DUKA AB, Sweden) at the lowest speed, “Speed 1” (about 95 rpm), for 60 s. About 40 g of the blend was then transferred to a Brabender plasticorder PL2000 with a M50EHT measuring head and kneaded at 50 rpm for 2 min.

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...
- 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.
- 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).
- 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.
- Are wheat gluten based bioplastics toxic?
- An extensive review of the existing literature reveals that wheat gluten (WG) based bioplastics are non toxics and fully biodegradable, hence in this review various plasticizers and cross-linking agents have been looked upon and their effect on properties studied.
- Does wheat gluten lignocellulose film reduce weight loss?
- Fruits, including cherry, litchi, and waxberry, stored in sterilized boxes and covered with wheat gluten lignocellulose nanofiber film showed the most edible rate and lowest weight loss compared to uncovered fruits and fruits covered with plastic wrap (Chen et al., 2022). The quality of cheese covered with wheat gluten–based film was investigated.
- Why is wheat gluten a good food packaging material?
- Effective food packaging that can protect foodstuffs from physical, chemical, and biological damage and maintain freshness and quality is essential to the food industry. Wheat gluten shows promise as food packaging materials due to its edibility, biodegradability, wide availability, low cost, film-forming potential, and high resistance to oxygen.
