Background and objectives:  High concentration of preservatives in food may result in gastrointestinal disturbances whereby some patients suffering from asthma, rhinitis, or urticaria. The aim of this study is the introduction and optimization a new method for simultaneous determination of four preservatives (SB, PS, MP, PP) in foodstuff by high performance liquid chromatography. Materi...

2. Thiomersal and timerfonate are organomercuric compounds used as preservatives in vaccines, antigens and immunoglobulins intended for use in humans and animals. At present these substances seem to best fulfil the requirements for efficacious preservatives used in inactivated vaccines because they do not react with antigen and are effective at very low concentrations. According to the recent s...

BACKGROUND IgE-independent (pseudoallergic) reactions to food and food ingredients are common in a subgroup of adult patients with chronic urticaria, who have daily spontaneous occurrence of wheals. However, for children with chronic urticaria (duration longer than 6 weeks, no physical influence), no data on the importance of pseudoallergen-induced chronic urticaria are available. Therefore, we...

The microbial safety of foods continues to be a major concern to consumers, regulatory agencies and food industries throughout the world. Many food preservation strategies have been used traditionally for the control of microbial spoilage in foods but the contamination of food and spoilage by microorganisms is a problem yet to be controlled adequately. Although synthetic antimicrobials are appr...

What Is Food Irradiation Food irradiation preserves meat, produce, and seasonings with highenergy gamma rays to improve product safety and shelf life. Spices, seasonings, potatoes, fresh fruits and vegetables, and meats and poultry may be irradiated. This method of preservation prevents growth of food poisoning bacteria, destroys parasites, and delays ripening of fruits and vegetables. Food irr...

Essential oils are aromatic and volatile liquids extracted from plants. The chemicals in essential oils are secondary metabolites, which play an important role in plant defense as they often possess antimicrobial properties. The interest in essential oils and their application in food preservation has been amplified in recent years by an increasingly negative consumer perception of synthetic pr...
