N2 - H. illucens, black soldier fly larvae (BSFL) is one of the sustainable sources of protein. However, the research on the functionality of BSFL proteins is limited and need to be explored to increase consumer acceptance. The aim of this study is to create a gel system from BSFL protein and evaluate the impact of ultrasound treatment at different exposure time (5, 15, 30 min) on the physicochemical properties of BSFL protein. The highest values for surface hydrophobicity, size, ζ-potential were obtained after 15 min of ultrasound treatment and the same was found for the elastic modulus. Finally, confocal laser scanning microscopy (CLSM) along with image analysis revealed the lowest pore size after 15 min of treatment. The high protein content of BSFL protein extract and its promising gel system herein created, are important features to be considered for further development of insect-based food.
