The Impact

Considering environmental pollution caused by the non-biodegradable polymers used in food packaging, developing and enhancing the properties of biodegradable films seem to be necessary. For this aim, in the present study, kefiran-whey protein isolate bionanocomposite films were prepared and the impact of different concentrations (1, 3 and 5% w/w) of Al2O3 (alumina) nanoparticles on their physical, morphological, thermal and mechanical properties was studied. Based on the obtained results, an increase in the nanoparticles content led to a significant decrease (p < 0.05) in the water vapor permeability, moisture absorption, moisture content, and water solubility. Scanning electron microscope images showed a homogeneous structure, confirming the good dispersion of alumina nanoparticles with smooth surface up to concentration of 3%. In addition, both thermal stability and mechanical properties of the films were improved by the increased concentrations of alumina. The results of X-ray diffraction indicated that the intensity of the crystalline peaks of film increased with the addition of Al2O3 to kefiran-whey protein isolate matrix. By considering all results, the concentration of 3% was proposed as the appropriate concentration of Al2O3 for the nano-reinforcement of kefiran-whey protein isolate bionanocomposites.

The Impact

Functional properties of protein macromolecules such as protein solubility are of particular interest to the food and nutrition industries as they have significant implications on other useful properties and characteristics for the development of nutritional and food supplements. Consequently, proteins with specific and consistent functional characteristics are in high demand as essential ingredients in formulated food or in pharmaceutical and industrial mixtures. Proteins need to be highly soluble so that their functional properties can be effectively exploited, therefore methods to improve the solubility of protein powders are currently being developed. It has been hypothesized that atmospheric plasma treatment has an effect on protein solubility and dispersibility. This theory has not been yet explored with whey protein isolate elsewhere; this study is the first to explore the impact of plasma based treatment. The effect of atmospheric plasma treatment on the solubility and dispersibility of dry protein powder has been studied. Each variable was examined using both a pristine sample of whey protein isolate and a sample of whey protein isolate from the same product batch that had been exposed to atmospheric plasma (following ISO 8156 and ISO/TS 17758 protocols). We demonstrate that plasma can successfully increase the solubility and dispersibility of whey protein powder.
