Marine food is on the rise due to an increase in capture and aquaculture worldwide. Marine food produces a large volume of waste because 50% of the food is not consumable; rather, it is traditionally disposed of in the environment. Therefore, different marine food species and waste have been studied to revitalize them and generate an economic impact. In this sense, diverse authors reported that marine food and waste are a rich source of bioactive compounds such as carotenoids, fatty acids, phenolic compounds, proteins, and vitamins, among other compounds. Therefore, different processes have been developed to extract these compounds, including conventional chemical extraction. However, a negative impact on the environment has been provoked, so alternative methods such as bioprocesses have been studied. Bioprocess as enzyme-assisted and fermentation are innovative processes that could be used as an alternative to conventional chemical extraction of bioactive compounds from marine food and waste because bioprocess methodologies with high purity and yield extraction have been developed.
