Ready-to-eat products elaborated with mechanically separated fish meat from waste processing: challenges and chemical quality

Both the worldwide demand for fish and aquaculture production have increased. Nevertheless, an extensive amount of fish production is destined for animal feed. Fish represents a rich source of nutrients necessary for good health, but it is highly perishable. This review contains descriptions of the relevance of the use of mechanically separated fish meat, which is considered a waste processing, for the manufacturing of semi- and ready-to-eat (RTE) products for human consumption and an evaluation of their chemical stability. Currently, consumers request nontraditional foods without risk to their health. Therefore, the development of innovative and healthy foods has been a challenge, mainly due to lack of knowledge and technology transfer to the industry.
