Status of shrimp peeling and pretreatment technology for facilitating peeling

Rapid peeling, a key technology in deep processing of shrimps,  is also  a harsh problem that has restricted the industrialization of shrimp processing industry. This paper reviews the status of shrimp peeling industry and the characteristics of tight connection in shell-meat, discusses the application and the potential utilization of traditional pre-treatment methods and novel high-tech as HP (High pressure), ultrasound, enzyme treatment and microwave in shrimps peeling. Furthermore, we propose the future trends of shrimp peeling industry, providesing references for solving the bottleneck problem of shrimp shelling and improving the technical level of shrimp processing industry.
