Insect production currently involves thermal processes to ensure microbial safety and inactivate endogenous enzymes, but these negatively affect the protein's technological properties. Therefore, this study compared high hydrostatic pressure (HHP) at 200/400/600 MPa for 10 min blanching 90 °C min, on soluble protein fractions (pH 3) from house crickets (Acheta domesticus) lesser mealworms (Alphitobius diaperinus). HHP significantly reduced load, especially 400 600 MPa. For aerobic counts of...
During the processing of insects for food and feed applications, thermal treatments are often used decontamination purposes. However, these denature proteins comprising their functional properties. Milder methods microbiological can be used, such as microfiltration. Therefore, in this study dead-end microfiltration (0.2 µm polyethersulphone membrane) was tested soluble fractions lesser mealworms house crickets obtained at pH values 3 8. The results showed that successful removal...
Insect-based food ingredients are emerging as sustainable protein sources, but their production requires ensuring microbial safety and inactivation of endogenous enzymes to avoid undesirable proteolysis, without compromising structure. While traditional thermal processing affects the structure, potential pulsed electric field (PEF) technology inactivate microorganisms in lesser mealworm house cricket slurries at pH 3 while simultaneously retaining native structure is yet unexplored. Lesser...
Insects are gaining attention as sustainable protein sources, necessitating the evaluation of gentle processing techniques for decontamination and fractionation edible insects. Microfiltration was shown to be an effective alternative thermal treatments microbial soluble insect protein. In this study, mealworm cricket fractions extracted at pH 3 8, obtained through a microfiltration (0.2 μm polyethersulphone membrane) process, were assessed. This process yielded cream layer, retentate...
