<p>IPRONA developed the proprietary <a href="{getUrl:97:en}-technology-ipt"><strong>IPRONA Polyphenol Technology (IPT)</strong></a>: an entirely mechanical, <strong>solvent-free </strong>separation, concentration and enrichment ultra-filtration process.</p>

<p>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. The <strong>high molecular weight fractions </strong>(larger molecules including polyphenols, anthocyanins and polysaccharides) are concentrated in one direction, the low molecular weight fractions (smaller molecules such as fructose and mineral salts) in another.<br />
This methodology allows for <strong>extracting without resorting to using solvents</strong>. The entire <strong>fruit matrix </strong>of the berry is <strong>retained</strong>, and the <strong>original flavour and aroma profile are maintained</strong>.</p>

<p><strong>*Craft&reg; </strong>extracts are water-soluble and <strong>standardised </strong>to a <strong>polyphenol and anthocyanin specification</strong>.</p>
