Hundreds of millions tons food resources are wasted annually due to microbial contamination. Effective packaging can prevent contamination and wastage. However, traditional has the problem low release bioactive substances. This study aimed prepare a pH-responsive polysaccharide hydrogel (GDPP) by double cross-linking ester hydrogen bonds that could result in high substances no residual peeling. The infrared results showed existence hydrogel, scanning electron microscopy porous network...

Additionally, provides an overview applications emergent non-thermal technologies for addressing these concerns production processing vegetables. It was found that vitamin C would commonly be lost, soluble protein degrade into free amino acids, new nutrient compositions produced, flavor correlated with chemical changes....

Edible film is now a trend in the food packaging industry. In this study, edible films were prepared by adding two Bacillus spp. (Bacillus amyloliquefaciens Y11 and velezensis Y12) to cassava starch carboxymethyl cellulose sodium matrix. The structural, physicochemical, biological characteristics of analyzed, its application salmon preservation was explored. had dense structure no pores, indicating that polymeric components compatible with each other. addition increased antioxidant activity...

Soluble dietary fiber (SDF) benefits human health, and different extraction methods might modify the structure functions of SDFs. Radish is rich in fiber. To assess impact various techniques on properties radish SDF, SDFs were obtained from white pomace using alkaline, ultrasonic-assisted, fermentation-assisted methods. Analysis was conducted structure, physicochemical characteristics, thermal properties, functional attributes The study revealed that can monosaccharides composition...

Abstract BACKGROUND Composite nanofiber films loaded with ε ‐polylysine (PL) and gallic acid (GA) were prepared using a zein/gelatin (ZG) electrospinning method to develop effective active packaging for tuna preservation. The morphology, structure, thermal stability, hydrophobicity, antibacterial, antioxidant properties of the films, their application during period storage 4 °C investigated. RESULTS PL reduced average diameter ZG fibers, whereas GA increased it. PL/GA/ZG film possessed well...

Pseudomonas fluorescens is a common specific spoilage organism (SSO) of aquatic products. The ability SSO can be regulated by the quorum sensing (QS) system. However, QS system in P. and their relationship with potential have not been systematically analyzed. In present study, complete genome PF08 isolated from turbot was sequenced. identification key genes that involved QS, enzyme synthesis, sulfur, amino acid metabolism explained PF08. Results quantitative real-time PCR revealed role...

Exopolysaccharides (EPSs) secreted by lactic acid bacteria have the potential to enhance human health showing various biological functions. This study investigated role and antibiofilm properties of EPS715, a new neutral EPS produced pickled vegetables originating from Lactobacillus plantarum PC715. The results indicate that EPS715 is primarily composed rhamnose, glucose, mannose. Its molecular weight (Mw) 47.87 kDa, containing an α-glucoside linkage α-pyranose ring. It showed amorphous...

The effect of fish oil (FO) on colonic function, immunity, and microbiota was investigated in Vibrio parahaemolyticus (Vp)-infected C57BL/6J mice. Mice intragastrically presupplemented with FO (4.0 mg) significantly reduced Vp infection as evidenced by stabilizing body weight reducing disease activity index score immune organ ratios. minimized pathological damage, strengthened the mucosal barrier, sustained epithelial permeability increasing crypt depth, goblet cell numbers, tight junctions...

The sea cucumber intestine (SI), a secondary product from processing, contains polysaccharides as one of its active ingredients, and fermentation is an effective method for extracting bioactive substances food by-products. In this study, to explore the effect

The N-acyl homoserine lactone (AHL) acylases are widely used as quorum sensing (QS) blockers to inhibit bacterial food spoilage. However, their substrate specificity for long-chain substrates weakens efficiency. In this study, a computer-assisted design of AHL acylase PF2571 was performed modify its scope. results showed that the variant PF2571H194Y, L221R could effectively quench N-hexanoyl-l-homoserine and N-octanoyl-l-homoserine without impairing activity against AHLs. Kinetic analysis...

Abstract Hafnia sp. was one of the specific spoilage bacteria in aquatic products, and aim study to investigate inhibition ability silver nanoparticles (AgNPs) biosynthesis by an aqueous extract Prunus persica leaves toward spoilage-related virulence factors The synthesized P-AgNPs were spherical, with a mean particle size 36.3 nm zeta potential 21.8 ± 1.33 mV. In addition, effects on growth two strains their quorum sensing regulated factors, such as formation biofilm, secretion...

Effective quorum sensing inhibitor (QSI) is an important way to solve microbial pollution. The traditional QSI screening method time-consuming and low accuracy. In order these problems, a more efficient accurate method, ligand fishing bound HPLC-MS coupled molecular docking technology, was developed. this study，Fe3O4@PS-ANTA-Ni2+ magnetic nanoparticles (MNPs) were synthesized in the first stage, with 97.4% capture of HalR (His-Tag) protein. Subsequently, MNPs fixed protein used fish for...

Gout, as the second major metabolic disease after cardiovascular disease. Peptides have advantages of natural and no side effects in treatment prevention gout. In this paper, xanthine oxidase (XOD) inhibitory peptides were screened from Scophthalmus maximus protein by ligand fishing technique. The specific results are follows: Immobilization 25.564 μg/mg modified magnetic beads, can be reused four times. Three decapeptides (FSLVHYAGTV, FTNEKLQQFF WDDMEKIWHH) screened, IC50 3.741, 4.046,...

Siderophore is an important spoilage factor in the process of Pseudomonas fragi, dominant bacterium aquatic products, and its secretion involved quorum sensing (QS). In this study, P. fragi (MS-10) which separated from tuna were used as test strain. Then, a mutant strain with deletion siderophore biosynthesis gene was constructed explored effects on growth tolerance, QS potential fragi. Results showed that siderophores slowed rate The apoptosis increased by 27.7% compared to wild at 4 °C...
