Alternatives for Efficient and Sustainable Production of Surimi: A Review

The links between fish processing and negative environmental impact need to be minimized. The over-exploitation of white fish stocks has compromised supply, the use of energy contributes to a high-carbon footprint, and the water resources required are also high. An option is to resort to the use of alternative species and fisheries by-catch, together with the maximum utilization of fish. In addition, edible proteins from a range of sources could be converted into added-value products using surimi-like processes. The surimi industry requires large amounts of freshwater and discharges wastewater with a high organic load. By exploring available options on processing technologies and management of the environmental impact, this review discusses the potential role of surimi and opportunities for sustainable fish processing.
