Special Issue Information

Dear Colleagues,

Proteins are often involved in food product design as functional ingredients and food components. The properties of proteins often depend on the structure‒function paradigm, which states that the polypeptide chain of proteins needs to fold into a stable three-dimensional (3D) structure, which is a prerequisite of the functioning of the protein. In the process of food processing and protein modification or extraction, however, more or less structural changes will be caused, thereby affecting the protein quality and function. The targeted design of processing strategies to modify protein structures and optimize protein functional properties is an effective way to improve food quality. While many physical and chemical strategies have been developed in recent years to improve the functional properties of food proteins, the potential mechanisms require further investigation and their industrial potential needs to be evaluated. Therefore, this Special Issue of Foods, entitled “Effects of Processing Technology on Protein Separation, Quality and Functional Characteristics”, invites works (original research papers or reviews) on the current state of knowledge of the subject. Specifically, this Special Issue should include, but is not limited to, the following points:

  • Separation, identification, and characterization of food proteins;
  • Novel physical or chemical processing strategies to modify food protein structure and function;
  • Innovative technology, modification methods to improve food protein quality, and functional characteristics;
  • Innovative design of protein-based food systems.

The low rehydration properties of commercial soy protein powder (SPI), a major plant−based food ingredient, have limited the development of plant−based foods. The present study proposes a treatment of soy lecithin modification combined with Alcalase hydrolysis to improve the rehydration of soy protein powder, as well as other processing properties (emulsification, viscosity). The results show that the soy protein–soy lecithin complex powder, which is hydrolyzed for 30 min (SPH–SL−30), has the smallest particle size, the smallest zeta potential, the highest surface hydrophobicity, and a uniform microstructure. In addition, the value of the ratio of the α−helical structure/β−folded structure was the smallest in the SPH–SL−30. After measuring the rehydration properties, emulsification properties, and viscosity, it was found that the SPH–SL−30 has the shortest wetting time of 3.04 min, the shortest dispersion time of 12.29 s, the highest solubility of 93.17%, the highest emulsifying activity of 32.42 m2/g, the highest emulsifying stability of 98.33 min, and the lowest viscosity of 0.98 pa.s. This indicates that the treatment of soy lecithin modification combined with Alcalase hydrolysis destroys the structure of soy protein, changes its physicochemical properties, and improves its functional properties. In this study, soy protein was modified by the treatment of soy lecithin modification combined with Alcalase hydrolysis to improve the processing characteristics of soy protein powders and to provide a theoretical basis for its high−value utilization in the plant−based food field.
