Process for preparing pomegranate extracts

摘要

Ellagitannins are extracted from whole pomegranate fruit, by carrying out extraction of said product in water, with a following separation step and purification step of the aqueous solution on adsorption resins and elution with a weakly basic aqueous solution. Independent claims are directed to pomegranate extracts or ellagitannin containing products with defined minimum amounts of punicalagin or punicalin. Further independent claims are directed to the extraction residue, to a plant for producing a pomegranate extract and to pomegranate extracts having defined contents of punicalagin or punicalin and comprising a beta glucan carrier.
