The texture of plant protein‐based meat analogs by high moisture extrusion: A review

Meat analogs produced by high moisture extrusion (HME) are considered to be one of the products that have great potential for replacing real meat. The key issue as a meat analog is whether the texture can meet the standards of real meat. Nowadays, there have been some advances in the textural characterization of meat analogs, which are discussed in detail in this review. Firstly, this review describes the current characterizations of meat analogs in terms of fiber structure, hardness, springiness, tensile resistant force and sensory evaluation. Then, methods for analyzing the texture of meat analogs, such as texture analyzer, microstructure-based methods, and other methods for characterizing fiber structure, are summarized. In addition, these characterizations are discussed in relation to the factors that influence the texture of meat analogs during HME. Finally, we propose priorities and some promising methods for future meat analogs conformation studies.
