High Antimicrobial Activity

Mirenat® is the range of formulated products based on LAE® (Lauric arginate) intended for food preservation.

LAE® is an innovative and non-toxic food preservative with high antimicrobial activity against all kind of Gram positive
bacteria such as Listeria monocytogenes, Leuconostoc mesenteroides and Staphylococus aureus
and Gram negative bacteria such as Salmonella spp., Escherichia coli and Campylobacter jejuni.

LAE® is an innocuous product that is rapidly metabolised in the digestive tract by hydrolysing into
natural compounds found in the human diet:


Non-essential amino acid, present in many food sources: cheese, poultry, seafood, nuts, seeds and cereals.

Lauric acid:

Present in coconut and palm kernel oil.


Alcohol produced by fermentation of sugars.

Mirenat® LAE® offers unique and valuable features - Mirenat® LAE® Food Preservative


No toxicity at doses of use, supported by multiple toxicological studies conducted in Huntingdon Life Sciences and other institutions (CSIC, University of Barcelona, SafePharm, ABC Research, EVIC, NOTOX and CIDASAL). It does not alter the product’s organoleptic features and it is resistant to all heat treatments (boiling, UHT and pasteurisation).


Its particular chemical structure allows that, once ingested, it is hydrolysed to common natural endogenous substances in humans (lauric acid, arginine and ethanol).


High activity against a wide spectrum of microorganisms: Gram positive and Gram negative bacteria, yeast and fungi, showing no resistance effect. It shows high effectiveness in a wide pH range (3-7) and it is chemically stable between this same range. LAE® disrupts the integrity of the microorganisms’ cell membrane.
