The concentration of EPS (among 0.5, 1, 1.5, and 2 %) and the ratio of EPS to essential oil (among 1:0.5, 1:1, 1:1.5, and 1:2) were initially optimized using vortexing.

The emulsion capacity, emulsion stability, the effect of various processing parameters (temperature and salt), and antimicrobial activity were determined for the emulsions prepared from vortexing, ultrasonication, and high shear homogenization. It was found that emulsion capacity and emulsion stability were better in ultrasonication and high shear homogenization treatment compared to vortexing. When these emulsions were treated with various temperatures and the effect of ionic strengths, the order of emulsion stability was recorded as ultrasonication > high shear homogenization > vortexing.

The anti-AD activities of FA + LP were evaluated through behavioral testing, measuring amyloid-beta (Aβ) and phosphorylated Tau (p-Tau) protein levels in the hippocampus and cortex, and assessing serum inflammatory factors. Transcriptomic analysis, coupled with quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and western blotting, was used to validate the molecular mechanism by which FA + LP improved AD pathology in mice. Finally, 16S rRNA sequencing technology was used to explore the anti-AD mechanisms of FA + LP from a gut microecology perspective. We found the optimal FA:LP synergistic ratio was 1:5. FA + LP treatment significantly improved cognitive function in behavioral tests while reducing Aβ and p-Tau accumulation in the hippocampus and cortex.

Corn silage, valued for its high energy content, balanced fiber, and palatability, supports both milk production and weight gain. However, its quality can be compromised by mycotoxins, microbial imbalances, and reduced aerobic stability, lowering its nutritional value. LAB strains, both homofermentative and heterofermentative, improve silage by boosting lactic acid production (10 % of dry matter), reducing pH (3.50–4.02), and minimizing ammonia nitrogen (NH<sub>3</sub>-N) levels. These actions enhance dry matter content, reduce fermentation losses, and improve stability and shelf life. LAB also lowers neutral detergent fiber (NDF) and acid detergent fiber (ADF) levels, increasing digestibility. Homofermentative LAB (<em>Lactobacillus plantarum</em>) improves silage palatability, intake, digestibility, and ruminant growth. Heterofermentative LAB (<em>Lactobacillus buchneri</em>) enhances intake but shows limited effects on development. Combining LAB with additives like carbohydrate-degrading enzymes or molasses further improves fermentation and digestibility. Despite these benefits, LAB inoculants have inconsistently boosted milk yield or composition in dairy cows. Future innovations in LAB strains or their integration with dietary fibers could enhance fiber degradation, carbohydrate availability, and silage nutrition, particularly in tropical systems.

The complexes formed with wheat gluten had a higher relative crystallinity, greater short-range order, and higher double-helix content, with smaller molecular volumes.
