Lactic acid bacteria (LAB) play a critical role in food production and health maintenance. There is an increasing interest in these species to reveal the many possible health benefits associated with them. The actions of LAB are species and strain specific, and depend on the amount of bacteria available in the gastrointestinal tract. Consumers are very concerned of chemical preservatives and pr...

Consumers are becoming more attentive towards the ingredients and preservation methods used for food preservation and pathogens control. The rapid globalization and use of chemical preservatives have changed the behaviors of foodborne pathogens. One of the most emerging problems is resistance to antibacterial compounds. Innovative and alternative approaches are getting appraisal to combat with ...

Nuclear factor erythroid 2 related factor 2 (Nrf2) is a transcription factor that mediates the upregulation of a battery of cytoprotective genes in response to cell stress. Recent studies have shown that Nrf2 also modulates immune responses and exhibits anti-inflammatory activity. In this report, we demonstrate that a common food preservative, tBHQ, can activate Nrf2 in T cells, as evidenced by...

There are various methods for the analysis of Potassium Sorbate and Sodium Benzoate in food products, but a rapid and reliable method for identification of these preservatives in Doogh (an Iranian traditional dairy drink) is a procedure, in which high performance liquid chromatography (HPLC) utilized and followed by UV diode array detection of the two preservatives. The aim of this case study w...

Sulfites and other preservatives are considered food additives to limit bacterial contamination, and are generally regarded as safe for consumption by governmental regulatory agencies at concentrations up to 5000 parts per million (ppm). Consumption of bactericidal and bacteriostatic drugs have been shown to damage beneficial bacteria in the human gut and this damage has been associated with se...
