BACKGROUND Regarding the public health concerns over the use of food preservatives in yoghurt drink "Doogh", the aim of this study was the determination of sodium benzoate, potassium sorbate and natamycin in Doogh. Based on Iranian national standard, none of these preservatives are permitted to be used in Doogh. METHODS A total of 39 Doogh samples were analyzed through RP-HPLC in order to qua...

The unending needs and demands for chemical free preservatives in food industry are on the increase due to facts that diseases like cancer complications from oxidative stress have been linked xenobiotics we eat foods as preservatives.

Consumers and industry experts frequently have negative perceptions of most chemical preservatives. Although people concede that they cannot resolve global food waste issues without preservatives, prefer products Numerous emerging technologies is now surpassing conventional methods for mitigating microbial deterioration in response to consumer demand fundamental health safety considerations, in...

A rapid quantitative assay of 14 antibiotics and 6 chemical preservatives by the cylinder-plate diffusion method is described, in which Bacillus stearothermophilus ATCC 12980 was used as the test organism. After 4 hr of incubation at 65 C, the zones of inhibition can be read off easily with the naked eye. The 4-hr assay was compared under identical conditions with the conventional 16- to 18-hr ...

Plant antimicrobials fulfil the needs of today’s consumer looking for wholesome food without chemical preservatives. These can be classified as novel compounds obtained from plants that delay microbial growth of pathogens and spoilage organisms in food. The antimicrobial activity of plant extracts that is observed in in-vitro conditions is quite different to its effect in complex food systems. ...

This paper describes the production, the purification and the antilisterial activity of amylolysin, a novel bacteriocin from B. amyloliquefaciens GA1. The strain genome was first analysed using PCR techniques for the presence of gene clusters that direct the synthesis of characterised bacteriocins from B. amyloliquefaciens and the closely related B. subtilis. Our results suggest that amylolysin...
