“…It is rich in proteins, amino acids, minerals, and polyunsaturated fatty acids 2, 3 . China, a major producer and consumer of tilapia, has been the largest exporter of tilapia in the world for 20 years 4 . Several by‐products are produced during tilapia processing, including minced meat, fish skin, and fish scale, which are rich in nutrients but may also cause serious pollution.…”

BACKGROUND The growing consumer demand for healthy products has encouraged the development of low‐salt meat products. In this study, to develop low‐salt restructured tilapia (Oreochromis mossambicus) meat products, citric acid was used to improve the properties of restructured tilapia products. RESULTS In comparison with control restructured fish products (RP) and surimi products (SP), 0.2% citric acid‐treated restructured fish products (RPC) and surimi products (SPC) showed a significant decrease in expressible water and water activity and a remarkable increase in whiteness, dry matter, hardness, chewiness, gumminess, and acceptability. Mechanistic studies suggested that citric acid significantly changed the content of total protein and myofibrillar proteins and promoted degradation of heavy myosin chains. Fourier‐transform infrared and Raman spectra revealed the citric acid‐mediated alteration in the peak intensities of amide I and amide II bands, which changed the secondary structures of RPC and SPC. CONCLUSION It is feasible to prepare low‐salt restructured tilapia meat products using citric acid, which offers a means of using muscle by‐products and exploiting new functional products with an added commercial value. © 2020 Society of Chemical Industry

“…Indeed, NO2prevents the development of extremely dangerous bacteria, such as clostridium botulinum, which generates the botulin toxin, responsible for muscular paralysis and neuronal complications (Cammack, Joannou, Cui, Martinez, Maraj, Hughes,1999). Furthermore, NO2is extensively used in food production because of its ability to react with meat myoglobin attributing a red colour to the treated meat (Wang, Yan, Su, Zhao, Xia, Chen, 2018). Despite several applications in the meat industry, NO2is reported to be one of the contaminants which can react with biogenic amines giving carcinogenic N-nitroso compounds (EFSA 2017a).…”

“…Intensive cultivation of Nile tilapia has steadily increased, especially in Asia, making it one of the most popular fish in terms of consumption (Roslan et al, 2014). China has an approximate production of Nile tilapia of 158 million tons per year, being the main producer country of Nile tilapia (Wang et al, 2018b). In 2016, Brazil was the largest producer of Nile tilapia in Latin America, with a production of approximately 240 thousand tons (El-Sayed, 2019).…”

The viscera and other residues from fish processing are commonly discarded by the fishing industry. These by-products can be a source of digestive enzymes with industrial and biotechnological potential. In this study, we aimed at the extraction, characterization, and application of acidic proteases from the stomach of Carangoides bartholomaei (Cuvier, 1833). A crude extract from the stomachs was obtained and submitted to a partial purification process by salting-out, which obtained a Purified Extract (PE) with a specific proteolytic activity of 54.0 U⋅mg-1. A purification of 1.9 fold and a yield of 41% were obtained. The PE presents two isoforms of acidic proteases and a maximum proteolytic activity at 45 °C and pH 2.0. The PE acidic proteolytic activity was stable in the pH range of 1.5 to 7.0 and temperature from 25 °C to 50 °C. Purified Extract kept 35% of its proteolytic activity at the presence of NaCl 15% (m/v) but was totally inhibited by pepstatin A. Purified Extract aspartic proteases presented high activity in the presence of heavy metals such as Cd2+, Hg2+, Pb2+, Al3+, and Cu2+. The utilization of PE as an enzymatic addictive in the collagen extraction from Nile tilapia scales has doubled the process yield. The results indicate the potential of these aspartic proteases for industrial and biotechnological applications.
