Possibility of Isolated Mung Bean Protein as a Main Raw Material in the Production of an Extruded High-Moisture Meat Analog.

As consumer demand for meat analogs continues to grow, various plant proteins are being explored for their production. This study uses isolated mung bean protein (IMBP) to replace isolated soy protein (ISP), investigating the effects of IMBP content (0%, 10%, 20%, 30%, 40%, and 50%) on the physicochemical and textural properties of high-moisture meat analogs (HMMAs) and exploring the potential of IMBP in the development and production of meat analogs. The results show that IMBP can bind water and cause protein denaturation, thus requiring more time and higher temperatures to be formed compared to HMMAs without IMBP.

Immunostimulatory potential of extruded plant-based meat: effect of extrusion moisture level on macrophage activation.
