Application of emerging technologies to control Salmonella in foods: A review
Salmonella is one of the major causes of foodborne illnesses in United States and many other parts of the world. The ubiquitous nature of the organisms and innumerous serotypes present in various foods make it challenging for researchers to strive for its elimination. In the past decade; various novel technologies have emerged with great potential […]
Further mycotoxin effects from climate change
Climate change will affect mycotoxins in food. The 2007 Intergovernmental Panel on Climate Change report is reinterpreted herein to account for what may occur with mycotoxins. Warmer weather; heat waves; greater precipitation and drought will have various impacts; depending on which regions of the world and mycotoxin systems are considered. The humidity issues are more […]
The influence of different nitrogen and carbon sources on mycotoxin production in Alternaria alternata
The aim of this study was to determine the influence of different carbon and nitrogen sources on the production of the mycotoxins alternariol (AOH); alternariol monomethyl ether (AME) and tenuazonic acid (TA) by Alternaria alternata at 28 °C using a semi-synthetic medium (modified Czapek-Dox broth) supplemented with nitrogen and carbon sources. Additionally the effect of […]
Effect of anilinopyrimidine resistance on aflatoxin production and fitness parameters in Aspergillus parasiticus Speare
ABSTRACT: Mutants of Aspergillus parasiticus resistant to the anilinopyrimidine fungicides were isolated at a high mutation frequency after UV-mutagenesis and selection on media containing cyprodinil. In vitro fungitoxicity tests resulted in the identification of two predominant resistant phenotypes that were highly (R1-phenotype) and moderately (R2-phenotype) resistant to the anilinopyrimidines cyprodinil; pyrimethanil and mepanipyrim. Cross-resistance studies […]
Native Australian fruit polyphenols inhibit COX-2 and iNOS expression in LPS-activated murine macrophages
Purified polyphenolic-rich extracts from four native Australian fruits; Illawarra Plum (Podocarpus elatus Endl.; Podocarpaceae); Kakadu Plum (Terminalia ferdinandiana Exell; Combretaceae); Muntries (Kunzea pomifera F. Muell.; Myrtaceae) and Native Currant (Acrotriche depressa R.Br.; Epacridaceae); were screened for their ability to modulate anti-inflammatory activity in LPS-activated murine macrophages (RAW 264.7). The Kakadu Plum extract inhibited the expression […]
Influence of light on food relevant fungi with emphasis on ochratoxin producing species
The influence of light of varying wavelength on growth and ochratoxin A biosynthesis of Aspergillus carbonarius; A. niger; A. steynii and on Penicillium nordicum and P. verrucosum was analysed. For comparison the influence of light on various other food relevant fungi; including citrinin producers; was also tested. Generally the Aspergilli seem to be more resistant […]
Nuts: Anti-atherogenic food?
The prevalence of cardiovascular disease as the leading cause of morbidity and mortality is increasing worldwide. This fact is mainly attributed to the modern lifestyle with predominant characteristics the change of dietary habits and the reduced physical activity which lead to metabolic disorders such as obesity and diabetes. Therefore; drastic dietary interventions are considered necessary […]
Dietary fiber; nuts and cardiovascular diseases.
Dietary fiber has a range of metabolic health benefits. Through a variety of mechanisms; dietary fiber; and the viscous variety in particular; slows down gastric emptying and intestinal transit; decreases the rate of intestinal carbohydrate absorption; and increases fecal bile acid excretion. Therefore; consumption of some types of soluble fiber can enhance satiety; which is […]
Nuts and Berries for Heart Health
Nuts are nutrient-dense foods with complex matrices rich in unsaturated fatty acids and other bioactive compounds; such as L-arginine; fiber; minerals; tocopherols; phytosterols; and polyphenols. By virtue of their unique composition; nuts are likely to beneficially impact heart health. Epidemiologic studies have associated nut consumption with a reduced incidence of coronary heart disease in both […]
Detoxification of Aflatoxin B1 and Patulin by Enterococcus faecium strains
Aim of the present study was to investigate the detoxification of aflatoxin B1 and patulin from aqueous solution by probiotic culture of Enterococcus faecium M74 and commercial culture of E. faecium EF031. The effect of the bacterial viability; incubation time and pH of the medium on the binding ability was tested. Also; binding stability was […]
