Description
For production of healthy and environmentally safe products the use of plant proteins is recognized as of highest importance. Plant proteins are an important group of molecules, offering a number of molecular interactions during processing and play a central role in the manufacturing of protein based food/non-food products. In this context, the plant protein structure and function are closely related, and a full control of them would guarantee the successful manufacturing of plant protein products. More understanding is needed on how plant protein structure and function are developed during processing of targeted protein products for innovative protein foods and proteins suitable for packaging applications.
Here we present a brief overview of the nano- and microstructure dynamics of plant proteins in various protein products by the use of X-ray scattering (SAXS and WAXS) in combination with other microstructural methods (SEM, TEM and X-ray tomography). The impact of additives (glycerol, cross-linking enzyme) and processing conditions (temperature and composition of the blend) during processing will be discussed. When studying wheat gliadin and glutenin films with different amounts of glycerol, we found that the nano-structural morphology of gliadin-glycerol films was greatly impacted by 20% and the higher amounts of glycerol (1). For the gliadin-enzyme food products, we found that the gliadin protein microstructure can be greatly steered by the use of specific additives and the type of enzyme.
