Nagardo® is derived by nature and sustainably produced.

With its natural properties Nagardo® natural beverage protection delivers additional marketing benefits to beverage manufacturers. Long desired natural labels and claims become reality.

Nagardo® is obtained as a purified mixture of naturally occurring glycolipids. The source organism is an edible fungus called Sweet Osmanthus Ear or Dacryopinax Spathularia which grows in (sub-)tropical climates. A non genetically modified proprietary wild-type strain is cultivated using renewable raw materials. Pure Nagardo® is recovered by a food grade and solvent-free process based on filtration and precipitation, without chemical modification.

New opportunities for beverage manufacturers:

  • Consumer friendly labelling
  • Natural claims (depending on local legislation)


Nagardo® is up to 50 times more efficient than chemical preservatives.

Nagardo® natural preservative for beverages shows very good efficacy against typical beverage spoiling microorganisms including yeasts, molds and bacteria. In addition, it controls microorganisms that have adapted or are less sensitive to currently used preservatives. It works by interacting with the microbial cell membrane and is chemically stable at pH values within a range between 2.5 to 7. Within a pH range of 2.5 to 4.6 it is most effective.

Tailored dosage is key – the recommended dosage needs to be determined individually for each beverage. We support you in finding the optimal quantity to receive reliable antimicrobial protection of your products at balanced costs.
