“…Microstructural observations were conducted on smokeless sausage, the best treatment of smoked sausage, and certain commercial smoked fish sausages brands as a comparison. Meanwhile, to support the analysis, the A W content and texture analysis were carried out using the penetrometer method [23,24] on those three samples.…”

Product diversification is needed to increase selling and marketing prices. One of them is the African catfish sausage product. Liquid smoke has been used commercially by the food industry. This study aimed to determine the physical and chemical properties of smoked African catfish after adding different concentrations of liquid smoke and immersion duration. The chemical analysis measured the levels of protein, fat, and phenol. The results showed that sausage with a concentration of 20% liquid and soaking for 30 minutes was the best treatment with a protein content of 43.8 ± 0.34%, a fat of 12.33 ± 0.61%, and phenol 292.74 ppm. Determination of the compound using GC-MS found that the most dominant compound in the smokeless sausage was 2-hexanone, 3,3 dimethyl with a relative concentration of 32.42%. The dominant compound in the besttreated sausage was Furan, tetrahydro-2,2-dimethyl- with a relative concentration of 19%. Liquid smoke penetration is clearly visible in the microstructure of smoked sausages, both in the best-treated smoked sausages and commercial sausages. Scanning Electron Microscope (SEM) magnification of 2.500x shows that the best emulsified smoked sausages have a flatter structure, smaller droplets, and are more refined than smokeless sausages or commercial smoked sausages.

Background: Contamination of freshwater ecosystems has become a major issue as it threatens public water sources as well as aquatic life. It is important to predict changes in organism health, given a known number of environmental factors and pollutant concentrations, in order to better manage contaminants through biomarker analysis. This study aims to examine the ecosystem health of the Brantas River based on its environmental condition and the hematology profile of Gambusia affinis fish present in the river. This species was chosen because of its wide distribution along the Brantas River, and because it is very tolerant, adaptable, highly abundant, and easy to catch. Methods: The study area included 10 sampling sites along the Brantas River watershed. In total, six water quality parameters were observed (temperature, pH, dissolved oxygen (DO), biological oxygen demand (BOD), ammonia concentration, and phenol concentration) and hematology measurements consisted of erythrocyte, leucocyte, and micronuclei analyses. Results: The results showed that the upstream area of Brantas River, located in Batu, was the least polluted region, while Mojokerto was the most polluted. The erythrocyte level of Gambusia affinis caught in most sampling sites was quite low. Furthermore, research revealed that the status of Gambusia affinis' hematological profile was significantly correlated (p<0.05) with water quality parameters, particularly DO, BOD, ammonia, and phenol. Conclusions: It can be concluded from these results that the hematological profile of the fish is poor due to high levels of organic waste and harmful substances.

“…Cadmium in gills has been measured both autopsies and in vivo [10]. In comparison, some other damage to gills is discussed in the previous article [8,11,12]. The destructive mechanism of Cd also occurs in the kidneys through the formation of Reactive Oxygen Species (ROS) and oxidative stress with nonenzymatic reactions.…”

This research aims to measure and analyze oxidative stress and ROS, aside from analyzing the detoxification mechanism in the gill of gambusia fish exposed to Cd. During maintenance and acclimatization, fish were fed pellets with smooth water circulation. After seven days of acclimation, the test fish were then transferred to a 4-liter aquarium. Before treatment, fish are fasted for 24 hours to ensure the stomach is empty. The study used 5 treatment groups with 1 control (C), treatment A: 0.03; B: 0.015; C: 0.011; D: 0.007; E: 0.003 (mg/L). The results showed a significant difference between the treatment and control groups (p <0.05). Treatments A and B were showed the highest reactive levels. Stress caused by Cd can increase ROS activity in the gill of gambusia fish. The production of ROS and the exposure to Cd stressors trigger the production of antioxidant enzymes such as catalase (CAT), hydrogen peroxide (H2O2), and superoxide dismutase (SOD). This study concludes that exposure to Cd in juvenile gambusia fish causes oxidative stress through increased antioxidant enzymes and ROS. Analysis related to the mechanism of detoxification of heavy metals in the body of juvenile gambusia fish.
