iprona Polyphenol Technology (IPT) is an entirely mechanical, solvent-free separation and enrichment ultra-filtration process.
This process utilizes specially-designed membranes with different pore sizes to separate pressed fruit juice into two streams based on the sizes of the molecules. Larger molecules including polyphenols and anthocyanins are concentrated in one direction, smaller molecules such as sugars and mineral salts in another. This methodology allows for -enrichment without resorting to using solvents. The entire fruit matrix of the berry is retained in the extract.
