“…UV absorption at 210 nm was used to detect the proteins. The chromatograms were divided into low molecular weight (0–13.5 elution time) and high molecular weight (13.5–25.0 elution time) for both the unprocessed WG (raw powder) and bio-based films, according to Blomfeldt et al 11 …”

A combination of genotype, cultivation environment, and protein separation procedure was used to modify the nanoscale morphology, polymerization, and chemical structure of glutenin proteins from wheat. A low-polymerized glutenin starting material was the key to protein–protein interactions mainly via SS cross-links during film formation, resulting in extended β-sheet structures and propensity toward the formation of nanoscale morphologies at molecular level. The properties of glutenin bioplastic films were enhanced by the selection of a genotype with a high number of cysteine residues in its chemical structure and cultivation environment with a short grain maturation period, both contributing positively to gluten strength. Thus, a combination of factors affected the structure of glutenins in bioplastic films by forming crystalline β-sheets and propensity toward the ordered nanostructures, thereby resulting in functional properties with high strength, stiffness, and extensibility.

Ultrasound effect on molecular weight reduction of amylopectin

Amylopectin is a major polymer found in native starch granules and presents wide applicability as a biomaterial because of its low cost and biocompatibility. However, in many cases, the use of polysaccharides with low molecular weight is needed, mainly due to the possibility to produce functionalized nanomaterials, as well as to increase their diffusion quality. An effective technique for reducing the molecular weight of polysaccharides without chemical structure alteration is the ultrasound technique. In this paper, amylopectin solubilized in DMSO 90% (v/v) was submitted to ultrasound treatment under various conditions. For the evaluation before and after ultrasound treatment, laser light scattering (LLS) techniques, and viscosity measurements accompanied by pH, conductivity and temperature observations were carried out. As a result of the ultrasound treatment a decrease in the size of the polymer chains and solution viscosity were observed in all the conditions analyzed, demonstrating a low-cost method for reducing the molecular weight of amylopectin.
