Yoon Hyun Ji conducted research titled ‘pH-responsive hydrogel delivery system of phage and prebiotics for targeted control of Klebsiella pneumoniae’. This work aimed to develop a delivery system capable of selectively releasing bacteriophages in response to external pH conditions, enabling targeted control of Klebsiella pneumoniae.

Student Lim Se Bin conducted research titled ‘Evaluation of Staphylococcus aureus biofilm formation and cross-contamination in a milk processing environment’. This study involved inducing Staphylococcus aureus biofilm formation under various conditions in a milk processing environment and quantitatively analyzing the cross-contamination transfer rate based on this.

Choi Yu Ri conducted research titled ‘Development of a pH-responsive pectin–chitosan bilayer carvacrol nanoemulsion for improving shrimp preservation’. She developed a pH-responsive pectin–chitosan-based intelligent nanoemulsion and evaluated its efficacy to enhance shrimp preservation.

Meanwhile, the Korean Society for Food Hygiene and Safety is the largest professional society in the field of food hygiene and safety in Korea. This academic conference was held under the theme ‘The Science of Food Safety: Bridging Research and Application’.
