Synthetic food additives pose serious threat to the consumers regarding food safety (which is a prime demand of the consumers). Herbs and spices as natural foodstuffs are the replacers synthetically formulated additives, leaving safety concern and providing prime quality food products. These naturally occurring additives have been traditionally used as medicine, flavoring agents and for the foo...

In this study, Suillus spp. after determining the dry matter and protein amounts of mushroom, antioxidant antimicrobial activities ethanolic extracts were investigated. Free radical scavenging activity was determined by DPPH method phenolic content HPLC. Antimicrobial against microorganisms that Staphylococcus aureus, Escherichia coli, Salmonella Typhimurium, Listeria monocytogenes Pseudomonas ...

At 56 weeks of age, 30 Hyline (W-377) laying pullets were randomly distributed in individual (1 pullet per cage) 45 x 45 x 35 cm cages. Cracked egg was used as protein supplement to the diet. Three groups of 10 Hyline laying pullets each were formed. Three isocaloric and isonitrogenous diets were prepared from different protein sources as followed: ration 1 (control) − soybean meal; ration 2 (e...

The aim of this study was to compare the growth rate of total viable counts (TVC), psychrotrophic viable counts (PVC), coliform bacteria and E. coli in portions of fresh common carp (Cyprinus carpio L.) under two different modified atmosphere packaging (experimental MAP1: 70% N2/30% CO2; experimental MAP2: 80% O2/20% CO2) and air (control samples) stored at +4 ± 0.5 °C, and to determine their s...

Grape seed extract (GSE) is a rich source of proanthocyanidins, a class of natural antioxidants reported to have wide-ranging bioactivity as anti-inflammatory, anticarcinogenic, and antimicrobial agents. The ability of GSE to rapidly inactivate Listeria monocytogenes in vitro and the generally recognized as safe status of GSE make this extract an attractive candidate for control of Listeria in ...

A lipoteichoic acid (LTA) was extracted from Listeria monocytogenes (serotype 1) by phenol-water partition and isolated by gel-filtration chromatography. The LTA exhibited amphiphilic properties by changes in gel-filtration mobility in the presence of detergent buffers and after mild base hydrolysis. In a hemagglutination assay, Listeria LTA bound antibody prepared against a known LTA from Stre...

Listeria app, isolated from 13 of 129 (10%) corn silage samples, 21 of 76 (28%) hay silage samples, and 3 of 5 (60%) grass silage samples during a previous Vermont survey were subjected to automated ribotype (RT) analysis. The 13 positive corn silage samples contained 3 Listeria monocytogenes isolated (three RTs, including one known clinical RT) and 10 L. innocua isolates (four RTs). Similarly,...

Although Salmonella spp., Escherichia coli O157, Listeria monocytogenes, Enterococcus faecalis and Clostridium spp. present a significant food safety and/or spoilage issue for the beef sector, there are limited data on their prevalence in Irish cattle. The objectives of this preliminary study were to investigate distribution (percentage farms positive) E. L. overall (%) these bacteria cattle sm...
