Fish Processing Industry Residues: A Review of Valuable Products Extraction and Characterization Methods

Abstract: Fish processing industry has experienced significant growth, playing an important role in the world economy. The increased exploration of marine resources contributes to the generation of considerable amounts of biowaste, which ends up as discards. In the face of the resultant disposal and environmental problems, many efforts have been made to deal with the fishery waste in more efficient ways. Nowadays, these by-products are regarded as important sources of high added value compounds, such as hydroxyapatite, … Show more

“…1 The conversion of fish by-products such as heads, bones, skins, and viscera, into economically attractive products could contribute to a more sustainable FPI. [1][2][3][4] In this domain, some of the most abundant by-products such as fish scales and bones, have an high content of mineral phase, mainly in the form of hydroxyapatite [Ca 10 (PO 4 ) 6 (OH) 2 -HAp]. 5 Due to its excellent biocompatibility with human tissue, HAp can be used to prepare calcium phosphate-based bioceramics which have been extensively used in the biomedical field in the last 20 years as coating of metallic prostheses, as cement for bone and dental implant, and as massive three-dimensional bone substitutes.…”

“…Considering the collagen molecule chemical composition, it can be described as a protein containing three polypeptide chains, each of which is composed of one or more regions containing an uninterrupted repeat of Gly-X-Y sequences, where X and Y can be any other amino acid residue. The sterical constraints due to proline and hydroxyproline cause the collagen regions with this tripeptide repeat to adopt three left-handed polypeptide chains (called α helices), which self-assemble to form at least one right-handed triple-helical domain [72,76,77], providing not only structural support for cells but, also, acting as an important regulator of cell behavior [78]. Collagen can be isolated from natural products, being relatively nonimmunogenic and, consequently biocompatible, opening the possibility to use it in a wide range of applications in commercial fields, including food [79,80], cosmetics [80][81][82], and medicine [72,[83][84][85][86].…”

“…Organismos aquáticos como vertebrados marinhos (mamíferos, peixes teleósteos e cartilaginosos), esponjas, estrelas-do-mar, anemônas-do-mar, águas-vivas e alguns crustáceos podem ser utilizados como alternativa dessa matéria-prima O tratamento enzimático é uma alternativa, porém, é usualmente realizada em associação ao tratamento químico. Nessa metodologia (método pepsina-solúvel (PSC), enzimas proteolíticas, frequentemente a pepsina, são utilizadas para aumentar a solubilidade das moléculas colagenosas através da quebra de algumas ligações peptídicas de forma específica, o que também contribui para uma menor geração de resíduos e aumento do rendimento ao final do processo da extração (IDEIA et al, 2019;BLANCO et al, 2017).…”

“…Própria com imagens de SMART -Servier Medical Art (2020).O processo de obtenção do colágeno passa por procedimentos de preparação (prétratamento), extração e recuperação e pode variar de acordo com a fonte, já que há variações no conteúdo, assim como ocorrem variações de acordo com a parte do animal utilizada (OLATUNJI, 2020). Inicialmente, é feita a limpeza e separação das amostras, seguido de um tratamento químico para desproteinização, desmineralização e desengorduramento (AHMED et al, 2020).O processo de hidrólise pode ser desempenhado com a utilização de metodologias que envolvem o emprego de soluções ácidas (GIRALDO-RIOS; RIOSZAPATA-MONTOYA, 2020), alcalinas, exposição a temperaturas elevadas(LIU et al, 2015) e atividade enzimática(IDEIA et al, 2019), como descrito com mais detalhes para a obtenção de gelatina e peptídeos nos tópicos a seguir.No método ácido-solúvel (ASC), geralmente são utilizadas solução ácidas para clivar ligações não-covalentes a fim de tornar o colágeno mais solúvel e remover moléculas nãocolagenosas sem danos a sua estrutura. Os ácidos mais comuns utilizados nas soluções são o ácido acético, ácido lático, ácido cítrico e ácido clorídrico (HCL)(LIM et al, 2019).…”
