Preparation and Properties of Biodegradable Films from Wheat Protein Isolate

Wheat gluten/montmorillonite biocomposites: Effect of pH on the mechanical properties and clay dispersion

“…In addition to the increase in plasticizing effect, however, the addition of acid prevents the wheat gluten cross-linking, thus accounting for the lower tensile strength and Young's modulus of the WGGW-SA samples. This trend was also observed by Baldwin et al [32] and Jagadeesh et al [33] for films containing solely plasticizers, whereas the plasticizer concentration increased, tensile strength was significantly decreased [34]. The effect of introducing layered silicates (MMT) in the wheat gluten matrix of WG-based bioplastics did not exhibit increases in the mechanical properties.…”

Ternary Biopolymer Based on Wheat Gluten, Whey Protein Concentrate and Montmorillonite

“…The elasticity and cohesiveness of gluten is used in development of strong edible films. The gluten films have good barrier properties for oxygen and carbon dioxide and are highly permeable to water [14,15]. Montmorillonite (MON), displaying a smectite-type structure, is one of the most commonly used layered silicates because of its quite low cost.…”

“…Adding of MON to WG objects produced by injection molding improved processability, plate homogeneity and tensile stiffness of the products [21]. Generally, protein based biodegradable materials are manufactured by two technological processes: a wet process technology based on dispersion of proteins and a dry process based on the thermoplastic properties of proteins under low-moisture conditions [14]. Whey proteins are very popular functional ingredient in foods.…”

Properties of Regenerated Cellulose Short Fibers/Cellulose Green Composite Films

“…In order to overcome these problems, now days, focus is slowly shifting towards utilizing biodegradable matrix and reinforcements in making green composites. PLA [1], Starch [2], SPI [3], WPI [4] etc. have been tried as biodegradable matrix materials.…”
