Special Issue Information

Dear Colleagues,

As the world’s protein requirement grows and carbon emission pressure on farming increases, there is a demand for the development and utilization of alternative proteins from different resources that can complement or partially replace the existing proteins.

Therefore, this Special Issue focused on using food thermal and non-thermal physical processing technologies to modify structural and physicochemical properties and improve the functionalities and digestion behaviors, the relation between structural and physicochemical properties, protein functionalities, and digestion behaviors.

Potential topics include, but are not limited to, the following:

  • Structural, physicochemical, functional, and digestive properties of food proteins from different resources, such as edible insect protein, fungal protein, RuBisco, and plant protein;
  • Effect of thermal food physical processing technologies, such as microwave, infrared, radio frequency, and ohmic, on the structural and physicochemical properties and functionalities and digestion of food proteins;
  • Effect of thermal food physical processing technologies, such as ultrasonics, pulsed electric/magnetic field, plasma, laser, ultraviolet, ultra-high pressure, and pulsed light, on the structural and physicochemical properties and functionalities and digestion of food proteins;
  • Effect of structural and physicochemical properties on protein functionalities and digestion;
  • Protein digestion under in vitro infant, adult (male and female), and elderly conditions and different in vitro models (static, semi-dynamic, and dynamic);
  • Effect of food matrix (solution, emulsion, and gel) on protein digestion.

Whey protein was pretreated with multi-frequency ultrasound in mono-, dual-, and tri-frequency modes. The effect of multi-frequency ultrasound pretreatment on the hardness, chemical forces, and microstructure of acid-induced whey protein gel was investigated. Whey protein gels pretreated with dual- and tri-frequency ultrasound showed higher hardness (p < 0.05) and a denser network than mono-frequency ultrasound and control. Moreover, they had higher hydrophobic interaction and lower disulfide bonds than the control (p < 0.05). The effect of gel properties on digestion was evaluated using an in vitro static model. Whey protein gels pretreated with dual- and tri-frequency ultrasound had a higher proportion of large fragments in the oral boluses than in the control. Large fragments (>3.35 mm) in those samples were resistant to gastric digestion. Moreover, the tri-frequency ultrasound pretreatment of whey protein gel released the least free amino group during gastric digestion. In contrast, whey protein gel with the mono-frequency ultrasound pretreatment released the highest amount of free amino acid group during intestinal digestion. Findings from this study suggests that gel hardness and network density could modulate the digestion behaviors of protein gels. Full article
