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. Additionally, increasing the IMBP content improves the gelling ability, thereby increasing the input of specific mechanical energy. As the IMBP content increases, the fibrous structure of the HMMA also increases. When the IMBP content reaches 40&ndash:50%, the most meat-like fibrous structure is observed. The water-holding capacity, water absorption capacity, springiness, and cohesiveness are negatively correlated with the IMBP content, while the oil absorption capacity is positively correlated with it. The integrity index and nitrogen solubility index show opposite trends with the increase in the IMBP content. When the IMBP content is 50%, the springiness and chewiness are the lowest, and the cutting strength is also the lowest, but the sample has a rich fibrous content, indicating that the HMMA with 50% IMBP content is soft and juicy. In conclusion, IMBP has the potential to be a substitute for ISP in the production of HMMAs.
