Monitoring fish freshness with pH-sensitive hydrogel films containing quercetin or eucalyptol.

This research developed pH-sensitive smart films using carboxymethyl cellulose (CMC) and collagen (COL), combined with either quercetin (QCT) or eucalyptol (EUC), to prevent fish meat spoilage. COL, extracted from isinglass, was confirmed as type I through SDS-PAGE. The films were characterized using FESEM, FTIR, and TGA.

Extraction and purification of α-pinene; a comprehensive review.

Extensive use of α-pinene in cosmetics, and medicine, especially for its antioxidant/antibacterial, and anti-cancer properties, and also as a flavoring agent, has made it a versatile product. α-Pinene (one of the two pinene isomers) is the most abundant terpene in nature. When extracting α-pinene from plants and, to a lesser extent, fruits, given that its purity is essential, purification methods should also be used as described in this study.

Facile synthesis of Cu NPs@FeO-lignosulfonate: Study of catalytic and antibacterial/antioxidant activities.

Environmental pollution is one of the important concerns for human health. There are different types of pollutants and techniques to eliminate them from the environment. We hereby report an efficient method for the remediation of environmental contaminants through the catalytic reduction of the selected pollutants.

The Lytic Siphophage vB_StyS-LmqsSP1 Reduces the Number of Salmonella enterica Serovar Typhimurium Isolates on Chicken Skin.

Phage-based biocontrol of bacteria is considered a natural approach to combat foodborne pathogens. Salmonella spp. are notifiable and highly prevalent pathogens that cause foodborne diseases worldwide.

Molecular detection, phylogenetic analysis, and antibacterial performance of lactic acid bacteria isolated from traditional cheeses, North-West Iran.

Lactic acid bacteria (LAB) are candidate probiotic bacteria that can provide health benefits when delivered via functional foods. The purpose of this study was to isolate and characterize LAB from traditional cheeses consumed in north-west regions of Iran. A number of sixty traditional cheeses samples were collected and initially screened as LAB using biochemical and molecular methods.

Saccharomyces cerevisiae as a delivery system of Zataria multiflora Boiss. essential oil as a natural preservative for food applications: Encapsulation of Iranian Zataria multiflora Boiss. essential oil.

Background: The following study is an evaluation of the encapsulation, stability and release profile of Iranian Zateria multiflora boiss essential oil (ZEO) in Saccharomyces cerevisiae yeast cells. Encapsulation was performed with different essential oil / yeast weight ratios at different temperatures. The encapsulation efficiency and stability of the loaded yeasts and the release profiles of carvacrol and thymol (as the main active ingredients of ZEO) were also investigated.

Isolation and toxin gene detection of () from traditional and commercial quail farms and packed quail meat for market supply - Short communication.

The design and application of a bacterial ghost vaccine to evaluate immune response and defense against avian pathogenic Escherichia coli O2:K1 serotype.

An Escherichia coli (E. coli) O2:K1 bacterial ghost was produced by controlled expression of bacteriophage PhiX 174 lysis gene E. Temperature controlled expression of this gene caused tunnels and holes in the cell wall of E.

Significance and Characteristics of in Poultry Products.

is one of the most common foodborne pathogens. Poultry meat and products are of the main vehicles of pathogenic strains of for human. Poultry products are part of the regular diet of people and, due to nutrient content, more content of protein, and less content of fat, gain more attention.

Phenotypic and genotypic study on antimicrobial resistance patterns of E. coli isolates from bovine mastitis.

It is important to evaluate the antimicrobial resistance pattern by genotypic and phenotypic methods in epidemiological studies in order to control antimicrobial resistance and to improve the outcome of the treatments. Four-hundred and thirty clinical mastitis samples were collected from 14 dairy herds in five different cities. The antimicrobial susceptibility test was performed using agar disk diffusion for 70 identified Escherichia coli isolates.

Enteritidis and Typhimorium identification in poultry carcasses.

Background And Objectives: Salmonellosis caused by spp. is one of the most important zoonotic diseases and transmits to human through raw food animal products including poultry meat. serovar Enteritidis and serovar Typhimurium are the most important strains that infect human.

Detection of in Retail Chicken Meat, Mashhad, Iran.

Poultry meat is one of the most important sources of infection of spp. for humans. The aim of the present study was to evaluate the incidence of in chicken meat by using culture method on selective medium and confirmation by PCR assay.
