Ultrasound-assisted, machine learning-optimized extraction of silver carp viscera fish oil and microencapsulation via complex coacervation.

Silver carp viscera, a lipid‑rich byproduct typically discarded, poses environmental pollution and resource wastage. Utilizing this byproduct for fish oil extraction offers a sustainable alternative; however, conventional enzymatic methods are inefficient, labor‑intensive to optimize, and yield oil susceptible to rapid oxidation. For the first time, this study developed an integrated ultrasound pretreatment and artificial neural network-genetic algorithm (ANN‑GA) strategy to maximize fish oil extraction efficiency, followed by microencapsulation in gelatin-hexametaphosphate complex coacervation microcapsules (GSM).

Survival of Escherichia coli O157:H7 and Listeria monocytogenes on Spinach and Blueberries Treated With Aqueous Chlorine Dioxide and Muscadine (Vitis rotundifolia) Extract.

The antimicrobial effect of various concentrations of chlorine dioxide (ClO) and muscadine extract (ME) was investigated on Escherichia coli O157:H7 and Listeria monocytogenes under in vitro conditions and on treated spinach and blueberries. Tryptic soy broth (TSB) and produce were inoculated with a 3-strain cocktail of each pathogen. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined using either 96-well plates incubated in a microplate reader for ClO or test tubes incubated in a conventional incubator at 37 °C for 24 h for the ME.

Resveratrol-myosin interaction: A novel strategy for mitigating quality deterioration in frozen sturgeon surimi.

Sturgeon meat, with a lipid content nearly four times that of silver carp, is highly susceptible to lipid and protein oxidation during frozen storage, leading to quality deterioration. We selected resveratrol (RES) from 32 polyphenols and identified its efficiency for preserving sturgeon surimi during 160 days at -20 °C. RES significantly inhibited lipid and protein oxidation, reduced myofibrillar protein (MP) degradation, and stabilized α-helix and β-sheet structures.

Mass Yields, Antioxidant and Anti-DU145 Prostate Cancer Cell Proliferation Properties of ProSoy Soymilk as Affected by Extraction Methods and Cooking.

Both the soybean variety and processing method affect the end soybean product's characteristics. This study's objective was to characterize the effects of four extraction methods (variations of soaking and grinding) combined with cooking on the content and composition of phenolic substances and the antioxidant and anti-DU145 prostate cancer cell proliferation properties of soymilks prepared from a yellow soybean of the ProSoy variety, which is a high-protein variety. The results showed that the soymilk processing yield was the greatest using method 4, although method 2 gave the highest solid and protein yields by about 14 and 12%, respectively.

Long-term effects of climate change on juvenile bull shark migratory patterns.

Seasonal variability in environmental conditions is a strong determinant of animal migrations, but warming temperatures associated with climate change are anticipated to alter this phenomenon with unknown consequences. We used a 40-year fishery-independent survey to assess how a changing climate has altered the migration timing, duration and first-year survival of juvenile bull sharks (Carcharhinus leucas). From 1982 to 2021, estuaries in the western Gulf of Mexico (Texas) experienced a mean increase of 1.
