Abstract(s)
As indústrias agroalimentares, incluindo a indústria pesqueira, produzem anualmente
grandes quantidades de subprodutos cuja valorização ainda é mínima ou praticamente
nula. Atualmente sabe-se que apenas uma pequena parte é reaproveitada para a
alimentação direta de animais ou para compostagem. Tendo em conta que esses
subprodutos contêm importantes teores de nutrientes e de compostos bioativos, são aqui
referidas algumas vias alternativas de aproveitamento dos subprodutos provenientes da
indústria pesqueira, nomeadamente para a indústria farmacêutica e cosmética.
Não obstante, deve-se ter em conta a importância da sustentabilidade visto ser um
conceito bastante complexo que envolve o desenvolvimento económico e social, sem
provocar grandes danos ao ambiente e aos recursos naturais. Atualmente existem
inúmeros casos de aproveitamento e consequente valorização de materiais que no
passado eram rejeitados pelas indústrias agroalimentares e que devem servir de exemplo
para todos os processos de produção alimentar, potenciando outras indústrias, como a
farmacêutica. Assim, a utilização de recursos subaproveitados, com o objetivo de
aumentar a produtividade e criar riqueza, terá de merecer, cada vez mais, maior atenção.
A nível nacional, um dos setores mais importantes é o da pesca. Atendendo à
importância que a indústria pesqueira exerce a nível nacional e internacional, tentou-se,
neste trabalho, caracterizar e valorizar os subprodutos gerados por esta atividade,
através de uma descrição detalhada da caracterização nutricional, química e das
propriedades biológicas dos constituintes presentes nestes resíduos e que podem
beneficiar, num futuro próximo, a indústria farmacêutica e cosmética.
The food industries, including the fishing industry, annually can produce large quantities of by-products whose valuation is still minimal or practically null. Currently, it is known that only a small part is reused for direct feeding of animals or for composting. Given that these by-products contain significant levels of nutrients and bioactive compounds, some alternative ways of using by-products from the fishing industry are mentioned in this work, namely for the pharmaceutical and cosmetic industry. Nevertheless, the importance of sustainability must be taken into account, since it is a concept quite complex involving the economic and social development, without causing major damage to the environment and natural resources. Currently there are numerous cases of exploitation and consequent recovery of natural materials, which in the past were rejected by the food industries, and should serve as an example for all food production processes, boosting other industries, including pharmaceuticals. Thus, the use of underutilized resources, with the aim of increasing productivity and creating wealth, will have to deserve more and more attention. For instance, at national level, one of the most important sectors is fishing. Given the importance that the fishing industry plays a national and international level, this study tried to characterize and enhance the products generated by this industry through a detailed description of the nutritional characterization, chemical and biological properties of the constituents present in these food residues that may benefit, in the near future, the pharmaceutical and cosmetic industry.
