The Secret of Solvent-Free Extraction

ElderCraft® European Black Elderberry Extract is not one single component. It's an active blend of natural fruit anthocyanins, polysaccharides and berry micronutrients achieved through a unique extraction process.

Iprona’s extraction technology is completely proprietary, compliant with all highest known quality standards and strongly rooted in our core belief that extracts destined for use in food supplements should not come in contact with solvents such as Methanol, Butanol or Ethanol. Ever.

This required innovation, which resulted in Iprona Polyphenol Technology (IPT).

Iprona Polyphenol Technology (IPT)

Iprona Polyphenol Technology (IPT) is an entirely physical, solvent-free separation, concentration and enrichment ultra-filtration process.

The process utilizes specially-designed membranes with different pore sizes to separate pressed juice into two streams based on the sizes of the molecules. Larger molecules including polyphenols and anthocyanins are concentrated in one direction through the membrane, smaller molecules such as fructose and mineral salts in another. This methodology allows for extracting without resorting to using solvents, and the phytonutrient fruit matrix of the berry is maintained.
