Alternative to Organic Acids: the Cimenol Ring
In other chapters of this blog, different preservatives have been described. In the last article, it was highlighted the need to look for another alternative to the organic acids, because they have some disadvantages: they are corrosive, lose efficacy over time and have a reduced spectrum of action.
For all these reasons, the use of a new preservative (Alquermold Natural) is recommended. It does not have any of the mentioned disadvantages. The active principle of this product is the cimenol ring. It is a chemical structure common in many molecules with preservative activity that can be found in plants traditionally used to preserve food or in ethnobotany.
The cimenol ring is found in aromatic plant extracts, such as Thymus vulgaris, Origanum majorana, Origanum vulgare, Mentha piperita, Ocimum basilicum, Salvia officinalis or Citrus limon.
The main property of the cimenol ring is its bactericidal and fugicidal activity, which has a different mechanism of action depending on the target microorganism:
Bacteria: the contact with the cimenol ring causes the expulsion of the cell content to the outside medium, as the cimenol perforate the cell membrane and, consequently, destroys de bacteria.
Yeast and fungi: apart from the perforation of the cell membrane, the cimenol ring inhibits ergosterol biosynthesis (the most important sterol for the yeastsâ€™ cell membrane), which contributes to cell destruction.
Thanks to the effectivity as a bactericide and fungicide, it is used to control intestinal pathogenic flora such as Salmoenlla, E. coli, Clostridium sp. or Staphylococcus sp.
Apart from the mentioned properties, the cimenol ring is also an antioxidant: it prevents fat oxidation to maintain feed palatability.
For all this reasons, we believe that natural preservatives (Alquermold Natural) represent a valid alternative to organic acids, because they are not corrosive, do not lose effectivity with time and have a broad spectrum of action.
