Wheat gluten–based coatings and films: Preparation, properties, and
This indicates that moisture content affected the tensile strength of wheat gluten–based film (Kayseriliolu et al., 2003). Compression and molding are widely used for making wheat gluten–based films, especially films that contain hydrophobic substances due to low compatibility in aqueous solutions (Wu et al., 2017).
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.
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.
Formulation of Pullulan/plasticizer blended films for their
The films made from (only) pullulan (10Pu), pullulan composited with sodium alginate (10Pu_0.5SA), gelatin (10Pu_0.5G), polyethylene glycol (10Pu_0.5PG), calcium chloride and lemon juice...
Edible wheat gluten (WG) protein films | SpringerLink
Commercial wheat gluten (WG) films, hard wheat gluten films and soft wheat gluten films, plasticized with glycerol have been cast from water–ethanol solutions. The effect of aging on various film properties has been investigated. The films were aged for about 6 months at 50% relative humidity and ~25 °C, and the mechanical (tensile strength and the percentage of elongation at break (E b
- 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).
- Can methylcellulose microfiber be used in glycerol-plasticized wheat gluten-based film?
- Incorporating methylcellulose microfiber (0%–42.8%, wt) into glycerol-plasticized wheat gluten–based film significantly increased the glass transition temperature, the film's elongation at break, and its tensile strength (Song & Zheng, 2009).
- 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 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.
