The antimicrobial activity of bioconversion extracts of EPA and DHA against a range of foodborne pathogenic bacteria was investigated. The bioconverted EPA and DHA exhibited antibacterial activities against four gram-positive bacteria, Bacillus subtilis, Listeria monocytogenes, Staphylococcus aureus (ATCC 6538) and S. aureus (KCTC 1916) and seven gram-negative bacteria, Enterobacter aerogenes, Escherichia coli, E. coli O157:H7, E. coli O157:H7 (human), Pseudomonas aeruginosa, Salmonella enteritidis and S. typhimurium. The growth inhibition by both bioconverted EPA and DHA was similar against gram-positive bacteria, while the bioconverted extract of DHA was more effective than EPA against gram-negative bacteria as determined by minimum inhibitory concentration.

This study investigated the effects of sequential high-pressure homogenization followed by heat treatment on the physicochemical properties and lipidomic characteristics of liquid egg (LE) and liquid egg yolk (LEY). After treatment, homogenization and heat-treated liquid egg (H-LE) and homogenization and heat-treated liquid egg yolk (H-LEY) exhibited significantly enhanced flowability and thermal stability, with gelation temperatures increasing from 65°C to 82°C for H-LE and from 82°C to 95°C for H-LEY. In vitro digestion analysis revealed that H-LE demonstrated a 14.

Animal feeding has a great impact on the management of beef farms, also affecting the nutritional properties of the meat. Therefore, in this study, the following two forage-to-concentrate ratios were tested on twenty farmed Podolian young bulls: high forage-to-concentrate (HF:C) ratio of 65:35 vs. low forage-to-concentrate (LF:C) ratio of 45:55.

(TM) meal is a potential alternative ingredient to plant and fishmeal in aquafeeds due to its high protein content, digestibility, and low environmental impact. However, its low n-3 PUFA (EPA and DHA) content represents one of its main limitations. This study evaluated the effects of replacing fishmeal and plant-derived ingredients (plant proteins and soybean oil) with full-fat TM meal on the growth performance and lipid composition of tissues in juvenile European seabass ().
