“…The values are below 2.0%, which is the result recommended by Ockerman and Hansen (1999). The result presented by samples A3 and A7 is similar to the values found by Caldato et al (2019), which was 1.44%.…”

“…In the extraction by the enzymatic method, different enzymes are used, such as pepsin, trypsin and collagenase. Pepsin is the most used in the extraction of collagen and can act alone after a previous extraction of collagen with acetic acid or in conjunction with the acetic acid solution, generating a soluble collagen with PSC pepsin (Caldato et al, 2019).…”

Evaluation of physicochemical properties of Nile tilapia skin collagen extracted in acid médium

et al. 2024

Tilapia has high-temperature tolerance, can breed in captivity, grow fast, and have excellent cost-benefit. Because of these characteristics, this species is of great interest in aquaculture and, currently, the most produced fish in Brazil. However, by increasing tilapia production, there was also a rise in the amount of organic waste, mainly from filleting, which discards 70% of waste. There are many studies on collagen extraction from tilapia skin as an alternative to reduce these residues and add commercial value. In this work, the extraction of protein concentrate was tested using an acid protocol, in which the tilapia skins underwent a pre-treatment in an acid medium and saline precipitation, with variations in time and concentration. After its extraction, the skin was evaluated for ash, moisture, protein, solubility, and pH. The protein concentrate obtained showed low ash contents, and the humidity is within those presented by the literature. The protein concentrate showed levels from 68.73 to 80.58% of protein and a low solubility between 4.03 to 6.93%. In conclusion, acid extraction is a possible means of collagen extraction, and tilapia skin is a good alternative to reuse waste generated in the fish industry.

“…De acordo com Balbinot (2015), aproximadamente 50% da biomassa do pescado torna-se resíduos sólidos, esses materiais são principalmente caracterizados pelas partes do peixe não comestíveis como cabeça, caudas, vísceras, pele e escamas (Feltes et al, 2010). A geração do resíduo de escama recebe destaque, chegando a corresponder aproximadamente 4% do resíduo seco produzido durante o manejo do pescado (Ghaly et al, 2013) e em termos de resíduos da produção de carne do peixe, cerca de 1% da massa se deve às escamas (Caldato;Zatta, 2019).…”

No brasil, a tilápia (Oreochromis niloticus) é atualmente o principal produto da psicultura. Tal fato desperta interesse e preocupação dos estudiosos levando ao questionamento fundamental sobre quais os danos ambientais gerados pela produção em larga escala dessa espécie. A geração do resíduo de escama recebe destaque, chegando a aproximadamente 4% do resíduo seco produzido durante o manejo do pescado. Um dos grandes impactos ambientais causados pelas atividades pesqueiras está na forma de destinação dos resíduos. O presente trabalho objetivou analisar a viabilidade da utilização de escamas de tilápia como fertilizante orgânico na composição de substratos para o cultivo de plantas de girassol, avaliando nas plantas: percentual de germinação; variáveis de crescimento (altura, número de folhas e diâmetro do caule); teores relativos de clorofila; e a produção de matéria seca da raiz, parte aérea e total. O experimento foi conduzido em uma casa de vegetação com os seguintes tratamentos: 1) 100% (em volume) de areia; 2) Areia + Adubo a 80 kg de N ha-1; 3) Areia + Escama de tilápia (EDT) a 30 kg de N ha-1; 4) Areia + EDT a 60 kg de N ha-1; 5) Areia + EDT a 90 kg de N ha-1; 6) Areia + EDT a 120 kg de N ha-1. Nas condições experimentais empregadas, a aplicação das escamas de tilápia ocasionou incrementos nas variáveis de crescimento analisadas (altura da planta, diâmetro do caule, número de folhas, teores relativos de clorofila, percentual de germinação e matérias secas da parte aérea, da raiz e total), principalmente na concentração de EDT a 120 Kg de N ha-1.

“…On the other hand, the skin and scales could represent biomimetic components to the human body if properly collected and processed (CALDATO; NAVES; ZATTA, 2019;JEONG et al, 2019). The use of these natural by-products for the development of composite implants could be useful in the technological roadmap of new biomedical devices from the perspective of global sustainability and the circular economy, using waste recovery technologies to obtain high valueadded products (CALDATO; NAVES; ZATTA, 2019;MARTINS et al, 2018).…”

“…Gelatin can be extracted from tilapia skin and it contains collagen type I (ALVES et al, 2018;OUYANG et al, 2018). Tilapia scales are a source of collagen and hydroxyapatite, with a high concentration of calcium and phosphate (CALDATO; NAVES; ZATTA, 2019;MARTINS et al, 2018). Such a combination, in the form of a tissue scaffold, may be a good biomaterial candidate for application in bone regeneration (JEONG et al, 2019;OUYANG et al, 2018).…”

Fish farming by-products could represent large-scale raw materials for xenogeneic implants that could be used for bone regeneration. The objective of this research was to analyze the biocompatibility and biodegradation of gelatin (G) and apatite (A) membranes from Nile tilapia. Adult male Swiss mice underwent subcutaneous implantation of biocomposites derived from skins and scales in different concentrations: 60%G:40%A (G1), 70%G:30%A (G2) and 80%G:20%A (G3). Commercial collagen membrane (C+) or implantless surgery (C-) were used as controls. Euthanasia was performed at 1, 3 or 9 weeks for histological analysis of the infl ammatory and repair criteria as well as the integrity of each material. The statistical analysis of non-parametric data was performed using the Kruskal-Wallis test and post-hoc Dunn test, with p < 0.05. In vivo results during the experimental period demonstrated progressive improvement in biocompatibility, with G1 and G2 being slightly irritating and G3 non-irritating, just like C+. There were signifi cant differences between test and control groups regarding the presence of neutrophils, lymphocytes, macrophages, foreign body giant cells, neovascularization and connective tissue. There was also a decrease in the integrity of the implants, where G1 maintained greater stability than G3 and G2, but less than C+. All biocomposites proved to be biocompatible and partially biodegradable. G1 suggests greater potential for use as an osteopromoting membrane, with its biological performance associated with higher mineral concentration compared to the organic phase. Future long-term orthotopic studies will be conducted to investigate its osteopromoting action.
