Special Issue Information

Dear Colleagues,

Food enzymology has been an important branch in food science and technology due to the active roles of enzymes in the fields of food production, processing, analysis, safety, and control. Meanwhile, the obvious intrinsic drawbacks (e.g., expensive, vulnerable, source-limited) of enzymes have inspired the evolution of artificial augmentation and biomimicry for enzymatic technologies. Nanobiocatalysis has emerged as one of the most cutting-edge developments for the field. In the agri-food sector, increasing achievements have been witnessed in investigating the usability of nanozymes and nanobiocatalysts in food detection, control, and beyond. This Special Issue aims to provide selected contributions on advances in nanobiocatalysis research with regard to food-related applications in food detection, preservation, cleaning, nutrition, and waste processing. Potential topics include but are not limited to:

  • Biocatalytic nanotechnology;
  • Agri-food and environmental detection;
  • Nano-immobilization of enzymes;
  • Nanobiocatalysis for decontamination;
  • Nano-enzyme systems;
  • Nanobiocatalysis against pathogen threats;
  • Food preservation;
  • Nanotoxicity of nanozymes;
  • Future perspectives for food nanozymology.

Quantitative evaluation of the antioxidant capacity of foods is of great significance for estimating food’s nutritional value and preventing oxidative changes in food. Herein, we demonstrated an easy and selective colorimetric method for the total antioxidant capacity (TAC) assay based on 3,3’,5,5’-tetramethyl-benzidine (TMB), hydrogen peroxide (H2O2) and synthetic Lycium barbarum polysaccharide-iron (III) chelate (LBPIC) with high peroxidase (POD)-like activity. The results of steady-state kinetics study showed that the Km values of LBPIC toward H2O2 and TMB were 5.54 mM and 0.16 mM, respectively. The detection parameters were optimized, and the linear interval and limit of detection (LOD) were determined to be 2–100 μM and 1.51 μM, respectively. Additionally, a subsequent study of the determination of TAC in six commercial fruit and vegetable beverages using the established method was successfully carried out. The results implied an expanded application of polysaccharide-iron (III) chelates with enzymatic activity in food antioxidant analysis and other biosensing fields. Full article
